[@quirinonavarro1857]

15:12 I was thinking, and is my humble opinion: the design of the lifter’s grooves have the simple porpoise of deliver pressurized oil to the rocker arms in a timed fashion, when the cam elevates the lifter, the groove in the lifter match the oil supply in the lifter bore, at the same time, the pushrod pushes the rocker arm and all the gaps turn to zero and the pressurized oil reaches the fulcrum of the rocker arm. And, when the cam release the lifter down, the groove in the lifter aligns with the oil gallery letting the free pass of the oil to the next lifter bore… that is my opinion. Saludos and keep up whit your great job!!

[@redshirt-scotty]

you are correct. there are errors of fact in hoovers blog that are being repeated in this vid. start with the 8% oil supply. it's pretty easy to show that that's a complete steaming pile from the back end of a horse. don't forget that since the pushrod is in motion that the oil in the pushrod will try run out the back of the rod during initial valve lift off the seat and upon returning to the seat. at these times the oil tries to run backwards through the tube and the vw engineers knew this and purposely built the lifter with the 2 rings or bands. cut channels in the lifter and you break a carefully engineered oiling system because some hack in the 50's decided this was the thing to do. hoover has some good info in his blog but this mod isn't worth the time it took me to read about it. you should sub to my channel as i'm putting together a scathing review of this mod. i should have it posted sometime in the next few days to a week.

Excellent video friend, I send you greetings from Paraguay, could you guide me what types of bits to use the long, how many CM does it have and what size would it be?

[@eugenesellors7207]

Hi , great report, followed your spec perfectly on two cases, no dramas, however on a Mexico as41 case went through the case, noted the oil galley descended from first cam follower to the next and so forth, about 4mm from front to back. And as such drilled through outer case. Worth checking this first, if the galley is not straight, it cannot be drilled successfully! Great video btw

[@VintageVolks]

Yeah, that is exactly what happens. It can go the other way too, where the drilling rises and you drill out on the inside of the case. That way is easier to fix since you can reach it with a TIG torch. It is easy to measure with a milling machine to see if you will drill through the side of the case, but not everyone has access to one. I have not figured out an easy way for a home gamer to verify before drilling. BTW - If you want to save the Mexi case, let me know and we can get you a price.

Hello. I would like to know if you could authorize me to use your video on my channel to explain in more detail how the VW aircooled engine works. I'm from Brazil and unfortunately most people who are interested in the topic don't know how to speak English.

[@arfelmcfarfel]

How much of a drop in cylinder head temperature do you see? (stock 1500SP) Thx

[@plastite]

Thanks a lot. Just scrapped a case doing this. Mexico cases are thinner and can not be drilled.

[@VintageVolks]

Which side of the case did you drill through? Both sides can be fixed, but the inside is much easier than the outside.

[@Charliealso]

Watched this a couple times: how does the oil get in to lubricate the lifters?

[@allenbrian72]

Ok how do you seal the hole in the bell housing where you inserted the drill bit

[@fabriciorcosta]

Hello my friend.....I am following hour vídeos from Brazil.....nice vídeos. Thanks.

[@billvolley]

I have a Brazilian VW case that I converted to full flow. First engine start blew up the oil cooler. Second engine start blew out the oil filter gasket. In trying to diagnose the high oil pressure, I took out the rear pressure relief valve and still had over 100 psi. I finally found a Berg pressure relief pump cover that fixed the problem. My question is, why are the oil pressures so high to begin with. My engine is not making metal.

[@VintageVolks]

I've not see an engine produce that much pressure. But with no details, it would be really hard to say what might be wrong. Make sure you are not running oil that is too thick. Many guys will run 20/50, but I personally run SAE 30 in my VW motors. Make sure the pump is not too large. There is absolutely no reason to run anything larger than a 26mm pump on the street if you blueprint the pump.

[@vwsandvettes3253]

Who or what is the "Kirk's VW" mentioned at 5:33 or so?

[@VintageVolks]

"Crook's VW". It is a joke. It's your local VW mechanic that does a shitty job and charges you way too much for it. It is not any one particular shop, but every town has one.

[@DonziGT230]

Have you ever looked at a running engine with the valve cover off to see if oil actually sprays the springs from that slot in the rocker?

[@thestove2407]

I ran with no valve covers this week. Almost no oil drips off the rocker assembly ! Hot engine, fresh oil, various revs for 5 minutes, up to 3000rpm. And you are lucky to see a drip every 15 seconds ! And that makes sense, as there just isn't enough gap for oil to flow. What bearings run on is a thing called static pressure. Lots of oil pressure and little flow. Thats exactly what bearing need ! You'd need at least a .004" bearing gap for any kind of oil flow. We don't have that around the rocker arms. We have about .001" gap = almost zero oil flow. One thing the vw engine has .. is the lifters and pushrods. Between the shaking actions of the hollow push-rods, and trapping of the oil .. you get breif spikes oil pressure ... up into the thousands of psi in the pushrods. That ton of psi is exactly what protects your lifter bores, exactly when they need it. Oh, and grinding that groove between the two oil rings ... destroys that high oil pressure, leaving you with worn lifter bores, and compromised rocker lubrication.

[@DonziGT230]

@@thestove2407 Did you do all the mods he showed?

[@thestove2407]

@DonziGT230 Hoover was a dolt who knew nothing about engines or lubrication. Hoover did absolutely zero documentation before or after his mods. Or he would have realized he was chasing the wrong theory. All linear bearing rely on static pressure ... not increased flow ! Hoover mistakenly thought linear bearings, like our crank, cam, lifters, and rockers .. needed more oil flow. They don't ! Increased flow does nothing .. as linear bearings are designed for static pressure because of the bearing's .001" gap .. Those style of bearings .. rey rely on a tight oil restriction as it's basis for lubrication. Hoover mods are a joke, and people are still laughing ... Every hoov-mod destroys pressure, and more flow is never ever going to happen. Well ... it will happen, as his mods will ruin your engine, as every hoov-mod decreases pressure. BTW.. vw oil pressure is governed by the front oil pressure relief valve. Vw engine oil psi ... is dependent upon that Spring. P.S. .... larger oil pumps .. only cause more oil pressure, and more oil pressure, depresses the oil by-pass valve... and that diverts oil from your oil cooler ... creating .. an even more hotter engine. Hoover was a fool who chased the wrong oil bearing theory. The vw oil pump is a static pressure pump ..not a high flow volumetric impeller style pump ... All these hoover mods .. will ruin your vw engine ! All Hoov-mods .. are a fools errand ! 🎉

HI. I see such a mess modification necessary on the type 4 case?

[@bobtomica9614]

Which engine bearing is better? KS, GLYCO or SILVER (Mexico)?

[@triariicat8448]

what happens if that burr slips and gouges that machined surface where the cam goes?

[@fixitallpaul4847]

For those that dont know. Do not put synthetic oil in your air cooled motor. Synthetic does not pick up heat and release it like conventional oil. It does not suffer from thermal breakdown. So even though you may have a good oil temp your heads could be over heating. Gene Berg wrote a paper about this.

[@desert4seat]

Great tip. I was told that it’s a good idea to use synthetic oil during engine assembly though…. For lubing internals and valve train, etc

[@Albertosalat]

Finally a video explaining how to do hoover mods properly!! Nice video, I'm waiting to see which are the stock rocker mods. I will do every mod on my next engine build (1968cc) Does the stock oil cooler work well with this mods or a external oil cooler is needed? Thanks a lot and keep posting this kind of videos!!

[@VintageVolks]

Thanks Alberto! We'll see what we can do about posting a video withe the modifications to the stock rockers. It's much more involved, so it really warrants its own video just on the rockers. Make sure to subscribe and click the notification bell so you know when we get it posted. The stock oil cooler is plenty. As long as your cooling tin is all installed correctly and you have a properly functioning thermostat, there is usually no need for an external cooler, at least for a naturally aspirated street motor.

[@VintageVolks]

That is a very good idea. We'll put it on the list and do before and after with head temps as well.

[@figitt88]

Am i to understand that we dont modify the center cam bearing ? just the case behind the bearing..? And i wonder if this will cause an increased oil quantity in the valve cover and possibly oil up the valve cover breather hose. ?

[@VintageVolks]

That is correct, you only modify the web and not the bearing. It will absolutely cause more oil in the valve covers, that is the whole point. That oil will flow through the pushrod tubes back to the sump carrying a bunch of heat with it. As long as the breather hoses in the valve covers are in the top corners, you will not see any issues with oil getting in the tubes.

[@edsoncorreia4235]

hello good afternoon... wouldn't it be ideal to increase the holes in the oil passage of the tappet housing by 2 millimeters?

[@VintageVolks]

The galleries in the lifter bores are already large enough to carry all the oil that can be delivered to them by the feeder passages. I've never had the need to make them bigger. Might be an interesting test though. I'll have to put together a junk motor just to try that out.

[@edsoncorreia4235]

@@VintageVolks Well, I ended up increasing it here on the motor on the side of the frame where the work is done for the oil circulation of the command in my vw1600. I will use a 30mm oil pump the original was 26mm.. let's see what happens

[@michaeltye5785]

probably a daft question but what do you do with the hole at the back of the fly wheel now you have drills the oil gallery cheers

[@VintageVolks]

You tap it to accept a 1/16" NPT plug. I like to use steel plugs with red Loctite so you can get them out. I find that the heads on the aluminum plugs strip to easily. Some people don't like the steel plugs because of the lack of thermal expansion and in theory they could leak. I have not seen that issue myself.

[@michaeltye5785]

do you do this processes on both halfs of the case or just one case I'm going to have a go

[@vincel6340]

Great video. I've heard the blocks made in Germany were stronger than the Mexican-made ones. If true, that means there are practically none of the German cases left.

[@HiTechDiver]

When you line bore a case, is it also wise to mill the mating surfaces of the two halves of the case the same amount of material as the line boring removed?

[@VintageVolks]

No, leave the case parting line alone. You should have the cylinder deck trimmed though, so you know it is parallel to the crank center line.

[@ooheasy01]

I have a aluminum case. Are these mods already dun on the aluminum cases??

[@VintageVolks]

Yes, the aluminum super cases have the same issues. We do these mods on them all the time.

[@jonathanfarmer3653]

When setting up the lifter, is there a reason you don’t just drill another hole in the second groove like the one has. If fear of oil pressure drop would be the issue, maybe half the diameter or so. Thoughts?

[@VintageVolks]

If you look at the grooves on the side of the lifter compared to the cup inside the lifter that accepts the push rod, you will see that the second groove is in the wrong location and you cannot drill a hole. It will simply create an internal oil leak and not send oil out the push rod to the head.

[@crissd8283]

Can you run an external line from the output of to cooler directly to the oil galley on the pad side of the engine?

[@VintageVolks]

What do you mean by "the pad side of the engine?" Are you asking if you could split your return line and have a direct line into the 1/2 side of the case? If so, the answer is no. There is no gallery end in the pully side of the case and no way to get a line between the flywheel and the case to inject oil in that end of the gallery. Going around the cam and enlarging those galleries is the best way we have found.

[@crissd8283]

Wow, that is too funny. We just did that last night and the plan was to film it but we ran out of time. We have another motor that is ready to be mocked up though, so we will film it in the next couple weeks. Fair warning though, it does take some specialized tools.

[@billkratzer9040]

any thoughts on building up the drilling areas with the new low temperature aluminium rods , before drilling ?

[@VintageVolks]

We have found that most cases have enough material to drill them out. But if I don't warn people and someone drills through the side of the case, they come screaming mad at us. When we do drill through, we have mag filer rod, so we TIG weld it back up, no big deal. For the home gamer, Alumaweld may work but I really have no idea. It would have to seal at some pretty good pressures.

[@randyyoung2135]

my oil pressure is great when the engine is cold but when it heats up the oil pressure goes down to less than 10lbs . What could be causing this ? how do I check the pressure relief valve for proper operation ?

[@VintageVolks]

There are a lot of things that could cause that issue. From the wrong oil, to warn main bearings. There are specifications for the pressure relief and oil control springs. I believe they can be found in the Without Guesswork books. You have to measure the spring pressure at a particular height and then compare it against the spec.

[@alumicomp]

Nice to see guy's putting some thought into solving a problem..! I can see where moving more oil through the heads can be a plus. Just curious as to whether you had documented the difference in oil flow from one side vs the other and did the modification bring them closer to being equal. Two things I did pay particular attention too, and that was the cylinder bore and the align bore. That appears to be bored for 94's and if I'm wrong it's a moot point, but have you ever considered step boring the holes to leave more material for at least the lower portion of the hole.? The other question is concerning the align boring; know that that case being a used case and knowing that after repeated run/heat cycles, there will be a certain amount of molecular movement. This is where the question come in..! Let me first say that it appears to be an excellent job of machine work, and I'm sure the bore of the housing is correct but how do you address the thrust. I have set an indicator to the inside of the case where the lip of the thrust bearing saddles over and I have always found that to have runout. I have a Truline Bar that I machined an eccentric with a carbide tool ( installed on my .020 ) bar and after I cut the housing I have a setup to clean a few thousands on the inside of the case to make it perpendicular to the centerline. I have another tool I made to then to cut the thrust to allow for a .001 press fit for the thrust and that I have found brings the case back to new spec. Have you found a better way to do this operation. Without the cleanup on the inside, there is no way to get a uniform press on the thrust around the entire circumference.

[@michaelibey6700]

I liked your comments and I do the same. I have a Mainliner and when I do the thrust cut I also clean up the thrust shoulder on the inside of the case. It only takes about .003/.005 and then I cut the rest from the front side. Best Wishes.

[@tubergenmotorsports4193]

Didn't quite understand tapping and plugging oil pump housing? So oil can't leak past? Plug what?

[@VintageVolks]

Plug the outlet side of the oil pump so oil is forced out the pump cover and to the filter. But, you also need to plug the matching gallery in the case so when oil returns to the case it cannot leak between the pump body and the case causing a drop in oil pressure at idle. Motors that do not have both passages plugged can, but do not always, have a dim or flickering oil pressure warning light at a hot idle.

[@TheAkstewie]

Would I benefit from this on my turbo motor?

[@michaelctanner]

NIce Vid! Is there any information comparing temps and oil volumes on 1&2? Does the trajectory of the rockerarm groove have to point directly towards the pad and why not do both sides of the arm? Any precautions necessary on aluminum cases with regards to drilling the galleys? Could you show the mods near the oil pump on a prepped case please? Thanks a lot!

[@VintageVolks]

Bob did a bunch of research on temps and volumes. That information is available on his blog still. Yes, you want that grove to point at or just below the pad, to spray the spring and valve stem. If you look at the way the rocker fits, putting a groove on the other side will not spray anything but the casting itself. The Super Cases can be drilled in exactly the same way. I'm not sure what you mean when you want to see the mods near the pump. Are you talking about tapping the galleries for full flow? That is nothing more then running a tap in the pump body and in the case itself. It really has nothing to do with the Hover Mods.

[@michaelctanner]

@@VintageVolks Thanks a lot!

[@wyomikey65]

Great video! I'm guessing because of the displacement for this engine, full blown mods like this are almost a must. What about for a seasonal daily driver. I have the original HO case from my 67 1500. I want to just build it up to maybe 1641. What oil cooling mods would you suggest...if any. I live in Wyoming so she's not driven during Winter and our climate rarely gets too 100 in Summer. Thanks!

[@VintageVolks]

We do these mods on all engines we build from stock to 2332cc. You can not have too much oil to the heads. The lack of oil in the factory design causes extra ware on the rockers in particular. It also allows more heat to build up in the springs which causes them to soften or fail earlier as well.

[@w124mercedes7]

Why would you use a mag case instead of a new purpose built aluminum performance case. Has anyone ever cut windows into valve cover and a case and spun the motor to see if it works or how much difference it makes in the lubrication system.

[@robertreents9238]

Your description of the lifter oil supply mod is misleading. You see (using your numbers), 8% of the time the lifter / pushrod is in motion and 92% it is stationary. So why would you need to supply oil to the lifter pushrod that isn't moving 92% of the time? That does not appear to be a needed mod.

Did Hoover ever mention that worn out lifter bores are responsible for low oil pressure? The factory didn't leave out the Hoover mods for cost. The biggest problem today are people who use old worn out and tweaked cases

[@VintageVolks]

That is very true, your engine must be within spec to maintain oil pressure. That does not change the fact that the oil system on a type-1 based case has some limitations that are very easy to overcome. Doing these modifications will not lower your oil pressure, as long as your pump will deliver enough oil after the modifications are made.

[@TheAkstewie]

SO. You cant do this unless you have a full flow set up?

[@VintageVolks]

You can do this without doing full flow but I would never do that. An oil filter will extend the life of your engine greatly. It will way offset the cost of doing the modification.

[@ednerin]

Does this apply to aluminum cases too? or are these mods incorporated in their design?

[@VintageVolks]

No, the aluminum cases do not have these modifications made to them. We do them on both the factory style aluminum cases as well as the bubble top/super cases.

[@yjmsrv]

I'm surprised the factory never figured this out and just had the blocks cast with the Hoover mods- or that these are not stock mods on aftermarket blocks by now. They're such simple and obvious solutions to a problem.

[@VintageVolks]

They did figure it out and Incorporated these changes into the Type-IV motor. VW also never put a filter on the Type-1 motor, at least not the German made ones, despite the fact that most cars had oil filters starting in the 60s. That is another modification that is easy to make and solves a real problem.

[@thestove2407]

I disagree .. hoover, for the most part ... was just solutions looking for problems. Hoover did absolutely zero tests to confirm that his mids worked ... of which, in fact, none actually did ! But original vw engines, with regular oil changes .. often lasted 500, 000 miles, and dealerships handed out watches and pins for such occasions. Sooo ... where were these "problems" to begin with ?

[@vintage76vipergreenBeetle]

Which oil pump do you guys use with the Hoover Mods engine cases? 26mm or 30mm?

[@VintageVolks]

We use the 26mm pump for street motors. 30mm is over kill and if your pressure relief and bypass valves are not setup correctly, you can have a situation where your oil bypasses the cooler even when it's hot. That is not a good place to be. It does not happen all the time, but the risk is there.

i have a german case i would like to send to ypu to have some machine work done ,

[@VintageVolks]

Sounds good. I got your number from a friend a while back. I'll give you a call later today.

[@slammenwagen]

Great video! Thanks guys!

[@whydahell3816]

Thats bad ass! Thank you man!

[@jp6940]

Duuuude! Absolutely amazingly to the point and well done video. One word.....SUBSCRIBED!

[@VintageVolks]

Thanks! We have plans for many more.

[@gorporpio]

Extra oil for cam thrust bearing if you don't do this.

[@1silvervespa]

Wonder if people using VW engines in Aircraft know these mods.

[@VintageVolks]

They do. Bob Hoover, the guy that came up with this, was big into flying VWs.

[@kw2519]

Those clamps on the rod cap surface is killing me lmfao hope there’s some brass between them

[@bondovwvw]

Are those AA performance rockers? Have you had good luck with them?

[@VintageVolks]

They are AA rockers and yes we have had good luck with them. The only issue we have ever seen is one adjuster screw broke on a customer, but he is VERY hard on his stuff so I can't say it was a manufacturing defect.

[@Uswesi1527]

Undoubtedly, but, definitely, experience pays.

[@sofianeadventure6755]

great job

[@erisgh0sted961]

Some know-it-all somewhere is watching this, thinking "yup that's fkd". 🤣😂

[@jaratt85]

You'd think someone would've figured out how to make roller lifters and rockers and hemi heads and stuff for VW's by now.

[@randombuilds8336]

They do have hemi heads and roller rockers available. Atleast they did a decade ago when I still messed with them.

[@jaratt85]

@Robie Billy I'm currently trying to figure out how to adapt a VW air cooled to a Porsche auto.. without spending 6k I don't have. It'd be great to have an automatic bug because my hip and back just can't stand a clutch in traffic anymore.

[@jb8086]

Find an autostick, get the joys of shifting gears without mashing a clutch. Neat little piece of engineering

[@jaratt85]

@@jb8086 again price and fitting it to a VW engine

[@jb8086]

Price varies according to car, there were bugs and ghias made from factory with autostick. I had a ‘69 bug with one, currently own a ‘70 bug autostick. They’re getting a little harder to find due to many being converted to 4 speed. Check the classifieds on TheSamba website look under 1968 and up type 1 cars and search “autostick” and “automatic stick shift”

[@alejandrocasas1455]

I did this to my case and now don't reach working temperature even with 8:1 compression ratio on a 2275cc engine 😜 I live in Mexico city Cheers!

[@termike55]

need to see the rocker squirters-squirt da springs

Oil "gallery"? Shouldn't it be oil galley?

[@VintageVolks]

No, it is called an oil gallery. www.automotivedictionary.org/Oil_gallery

[@seanpettit6410]

thanks guys...

[@sharonburns4788]

Oh the joy of German engineering, looks like an old Messerschmidt part.

[@vwdarrin]

I am going to need some serious help trying to build a super Street motor want to come out to California and race I do not have a car so I figure I will start with the motor. Also have a German case. ItWas the motor my old boss built had a Berg crank and jet rods slipper skirt 88’s and FK 89 had some of jeans heads on it also I prepped the car for 15 years when I worked for a scooter every time we raced it he got a new girlfriend and we stop racing together anyway he called me out of the blue we went and raced the car turns out he forgot to put oil in it it did not go very far lol OK still looks good but the lifter Boars or sloppy and need to be bushed. I will have to tell you the sharpie story one day lol when I worked for Brad Anderson my first day we had a serious thrash in the pits and Randy asked me to hand him the marks a lot did Know what he was talking about. I didn’t know some guys in California called the magic markers also lol

[@cocodog85]

perfect for an ultra light plane application.

[@VintageVolks]

Absolutely. Bob was very big in that community. Many of the engines he built were for "flying VWs" as he put it.

[@brettfoster6786]

1 AM. Your wife wakes up and seeing you drawing in your little.black book . she murders , hopeless gear head .

[@oddcarsandbaddecisions]

Magnesium fires get exciting! Better have a bucket of sand on hand, you don’t put them out with with water.
