Your absolutely right. Good quality filter and plug that bypass. Been doing this for 30 years

[@jacobnorth8642]

If you are attempting the new car 10000 mile BS oil change an expensive filter might help but just like the sealed for life transmissions, no maintenance ruins components. I have 200000 to over 300000 on my vehicles and i use cheap Walmart filters, change my oil every 3333 or 5000 miles depending on vehicle. The only ones i pony up extra cash for wix fliters is on my diesels.

[@miketee2444]

I always laughed at the cut away of a fram filter at parts stores. They use the bypass as a reason to discredit the brand. I'm definitely on board with bypassing oil as opposed to restricting it. If you've got much metal circulating then a filter isn't the issue anyway.

[@PeggyParrow]

Also use a 51061 wix oil filter , which has a very strong bypass, try it by using a long strong screw driver, set the filter up right on a bench put the driver down into the filter and push down as hard as you can. Good way to test one filter against the other . Hope this helps.

[@prestonrieger8410]

Roller cams and lifters are failing far too often nowadays too. It’s not just flat tappets. At least with a flat tappet cam you can measure lifter crown, and lobe taper to ensure the best chance of success. Joe Gibbs driven BR30 break in oil is a lifesaver as well.

[@sc358.]

Haven't built anything for a few years, unfamiliar with changes to part quality related to supply chain changes. But yes we used Driven. Also had infrequent failure of Jessel roller lifters. Went to bushed Morel.

probably from the removal of zinc because of emmissions...try Mobil one 15-50W.....

[@plumcrazy588]

We have seen a lot of these issues pop up on youtube and some engine builders actually started testing lifters and cams. From what I have seen the lifter tapers are machined wrong. About a week or so ago Muscle Car Solutions makes a video saying its critical to use the right combination of parts, use the correct break in oil, and to follow the procedure correctly. I just had to leave a comment bc it seems as though he might have a connection with Comp Cams. My point is this...there are engine builders who have been doing this out there for decades well before they changed the oil content back in the 90s and they switched to roller. My point was if you dont have the time or money to do it the first time will you have more time and money to fix it when it wipes a cam? I agree on your comment if you have the money go roller bc I'm sure the cam company isnt going to help you out any. If you go roller you should show the viewers how to install a retro cam and also which lifters.

[@cuttersperformance]

Thats the thing, I believe most of the issues are 1) Crap lifters *bad crown and surface hardness 2) Lifter bores on 40+ year old blocks are egg shaped (lifters not spinning) 3) Not using the proper oil and break in procedures. I dont feel right telling guys not to bother with flat tappets because not everyone can afford a roller cam setup but risks for flat tappets are real and guys need to educate themselves before deciding

[@frotobaggins7169]

Uncle Tony's Garage did a few videos on this topic. He concluded that the taper on the lobes of the cam needed to spin the lifter is not ground in to the cam correctly, thus not spinning the lifter and causing the damage. This seems to be a very common problem today no matter the cam manufacturer.

[@cuttersperformance]

Or not enough crown on the lifter face mixed with poor surface hardness. I checked both the lifters and cam crown and still didnt win o this one haha 😅

[@frotobaggins7169]

@@cuttersperformance Check out tony's video. Maybe he's right, maybe he's wrong, the bevel on the cam must be difficult to measure as well as the hardness. IT makes sense that the cam isn't spinning the lifter since the lifter has a groove worn in one place rather than being just worn down like a mushroom from lack of surface hardness. IDK It's definitely a problem industry wide. I hear many saying that Morel lifters and one other brand are the only good lifters left. As for the cam, it's all hit and miss I guess.

[@cuttersperformance]

@froto baggins no he's certainly right on that, thats why I check every flat tappet cam and lifters. Alot of guys dont realize the lifters have to spin if they dont spin right away the cam is screwed. Another major issue is that these old blocks have lifter bores and aren't so round anymore, preventing the lifter from spinning freely

[@frotobaggins7169]

@@cuttersperformance Yeah, I just think it's odd that it's never been a problem until recently. Many guys have used all the assembly lube, heavy duty oil and ZDDP additives and still have the problem. Even people who meticulously watched break in. It seems like it's tied to just total lack of quality control. It seems to effect just one or two lobes which makes me wonder if they have a bad grinding wheel or something. IDK

[@rustybritches6747]

You either worded that wrong or I interpreted it wrong or you weren't paying attention to what he was saying! the problem we're all having with lifters is surface hardness and the lifters not being ground with a dome on them, that's what's eating up the cams and lifters! The lobes on the camera also taper but it's usually the lifters fault unless you're buying a white box made in China can then you can pretty much guarantee failure with the hardening process being the least problematic! It's not just comp cams either there's literally a hundred different suppliers with different brand names when it comes to lifters but in reality there's only a handful of people that actually manufacture lifters, they just get rebranded.

[@yurimodin7333]

This is why I am only playing with factory roller blocks. Also my dad worked for one of the major oil filter manufacturers. The engineers told him that most filters usually plug up in the first 500 miles or so and the internal bypass in the filter opens anyway.

[@cuttersperformance]

Theres alot of fine metal particles in the first 20 mins of running from the cross hatch on the cylinders. Filters should be changed after the initial break with a flat tappet or roller if you want to be safe

[@ChrisMcCutcheon-wj2pp]

Crower and isky both make excellent parts, only thing I run from comp is push rods and rockers, I stopped using comp in the 90s, alot of these problems stem from oil ingredients being changed, I use moly grease on lobes and I run delo diesel oil for break in, right after break in, change the ac or fix filter on sbc

[@kennethcohagen3539]

TRW and probably other companies make oil pump drive shafts for SBCs that are solid steel instead of a shaft with a nylon bushing holding the pump and shaft together. That together with always using a new oil pump pick up tube and not putting tons of silicone on any seal will prevent most rebuilt engine failures.

[@jeremyhuston1]

Sorry to hear about your engine break-in failure. It's a lot of time and effort to have a failure at that point. I watch a lot of other motorsport channels on youtube and there are big problems with lifters failing. Brand-new ones are sketchy. It's gotten to the point of switching to rollers or reusing old lifters. Just an FYI. Keep up the great content.

Thanks for Sharing... All Tips Help

[@mikef-gi2dg]

According to Chevrolet service tip...a hydraulic lifter should rotate minimum 45 degrees for every two crank revolutions. It's the non rotation because of taper problem, and improper surface finish on mostly lifters that kills them.. Look at a new gm lifter to see what is proper. If you look at older lifters which survived with no problems...you will see normal wear, not gouging, in a circular pattern on the face of the lifter. The offset wear pattern ( not dead center of the face)shows why the lifter rotates. It took some digging to find this, plus looking at dozens of still functioning old lifters.

[@cuttersperformance]

Thats correct, some guys will even run them with no valve covers with a white line on the push rod to watch rotation

Always wondered why you needed that bypass with a good filter. I work with many other performance and stock engine builds that leave any bypass if at all to the filter internally. I have several engine builds in the near future, I'm going to have to rethink flat tappet use. I'm even hearing hydraulic roller sets that don't bleed down properly. Why do the street level solid roller cams have to be so expensive? What about street solid roller cams running factory hyd roller lifters with the internal plungers shimmed solid?

[@cuttersperformance]

Yeah, they are more, and dang lifters are just so expensive for retro fit. I've never shinmed a stock lifter solid other than for a checker lifter. The thought has certainly crossed my mind, maybe I will have to try it 🤔

Always check the crown on the lifters and the taper on the cam lobes before installing....there should be several thou on each....

I learned that the hard way 18 years ago when the oil filter bypass got stuck on my freshly built 383 wrecked the bearing in 3000 miles .

[@jchavins]

what's the difference ? Your cartridge oil filter has a spring in it that allows the oil to bypass the filter cartridge element above 25-30 psi anyway.....

[@ronniecox109]

not all a PH 30 does not have bypass, a PH 5 does ,but both fit a SBC.

[@edwardmalle210]

All filters are bypass filters......they all have springs in the top....so this feature is redundant anyway .... There's also a plug inside the block on SBCs between the oil pressure port on the rear China wall and under the rear main cap....most machine shops remove this when cleaning but they don't put them back in unless they're assembling the engine. The net result is that oil never gets filtered no matter what you do....

Like I said in the video, I would tell anyone to run no bypass during break-in, but if they want to swap out after the first oil change, that's their choice.

[@reason2gether]

Very good information. I am currently rebuilding my 327 because the cam went flat and debris made it into the bearings through the by-pass. If I am correct, it appears that the lobe of concern in your video is the same lobe that failed on mine, the # 6 cylinder exhaust lobe. I wonder if the location of the lobe in the engine has the least splash oiling or if the cam manufacturers hardening treatment somehow is inadequate in that area. I had two cams by the same manufacturer go bad on that same lobe. This is the first time I am going to use a non-bypass oil filter adapter (billet unit, not modified OEM) and an aftermarket Roller Cam. Your experience with them is a great reassurance that they work safely. Do you also use a hi-pressure, hi-volume pump as well? I am trying the new "shark-tooth" oil pump on this rebuild as well.

[@reason2gether]

I agree with the concept of plugging the by-pass. I also think it should stay plugged beyond the break-in process because a component failure can happen well after break-in and even with the roller cam, if a roller goes bad and the wheel comes apart, all the debris will do the same if allowed to go through the by-pass. Yes, block off the oil filter housing by-pass, AND use a filter that does not have an internal by-pass, otherwise you will defeat the purpose.

[@cuttersperformance]

Sorry to hear about your engine man. Im wondering if you have a egg shaped lifter bore? Two cams same lobe wouldn't be suprised. I run std pressure HV pumps on most builds I run a blocked bypass, with a non bapass fillter all the time, works perfectly 👍

[@reason2gether]

@@cuttersperformance That is good to hear, Thank you! As for the lifter bores, they are fine. I had initially run the hydraulic "151" cam in this engine for a few thousand miles with no issue. Only the later installed solid-lifter cams (both Ultradyne, same part #) failed starting at the # 6 exhaust lobe. I reviewed everything from spring height, spring pressure, lash settings (spec for those cams was .026" and set accordingly). The first cam failed within hours of break-in so I wrote it off as my mistake. The second cam though ran well for approximately 4,000 miles before failing. I believe metallurgy of either the cam or lifters were to blame. I intend to run a hydraulic roller this time and from now on. It is too expensive to trust in what you cannot see or verify. Such as surface hardness depth. I always run full synthetic after break-in, which flows better than conventional oil when cold. I also store this car during winter months, so chances of bursting an oil filter should be nearly 0 even without the by-pass. Thank you again for the reassurance and I look forward to more of your excellent videos my friend. God Bless.

OK so if the oil is 100 % filtered does it save all the rest of the engine from having to be taken apart and rebuilt after a cam failure like that .?

[@cuttersperformance]

@glennmanchester5696 yes exactly, you'll save the bearings

[@Just1Spark]

What about the filters with built in bypass?

[@johnwilleford7715]

So,how do you do this? Do you just screw this plug in a hole? Do you have to drill and tap the hole for the plug? What needs to happen?

[@will7its]

Tap it or get a stiffer bypass spring.

[@michaeledge8905]

No other manufacturer uses bypasses so should not be a problem eliminating it.

[@cuttersperformance]

Alot of modern deisgns puts a bypass in the filter rather than in the block or adapter

[@fbbc6495]

All my sbc chevy. But now I'm scared shitless of a flat tappit, and don't want to shit my motor, and don't have the cash for roller

[@joe-hp4nk]

All filters have their own a by-pass built into them.

[@cuttersperformance]

Not all filters do

[@will7its]

You can also put a washer under the spring to tighten it up or they make stiffer springs. Those chinese lifters suck, the guys over revved it or it was defective. Go roller......

[@cuttersperformance]

Never a bad idea to go roller. But we even run a plugged bypass on our 900hp super stock engine that runs upward of 10k rpm

[@DAT240Z72]

That’s NOT at all what the bypass is for!

[@cuttersperformance]

What do you think it's for?

[@larryw5429]

I take it the bypass wasn't plugged on the motor with wiped out lifter?

[@cuttersperformance]

It was plugged and thats what saved the bottom end. Often times a wiped lifter will causes major bearing damage as bypass opens allows the metal to go right past the filter into the bearings.

[@kimmorrison9169]

does this apply to my BBC as well?

[@cuttersperformance]

Yes

[@9ijnht5rdx]

And the bypass in the filter?

[@cuttersperformance]

@9ijnht5rdx Most sbc filters don't have an internal bypass in them (PH6, PH13, 51069, B6 ect) No internal bypass

[@born2wrench]

so how do you install the pipe plug

[@cameracamera1319]

Where does the plug go? In the block or in the filter adapter? What size and thread? Maybe i missed all that . Sorry

[@cuttersperformance]

All in the video my man. In the filter adapter 1/4 npt plug

[@wims58ej]

He said he made a video of it.

[@philipmazzuca2269]

Drill and tap the adapter for 1/4 and install a 1/4 pipe plug

[@cameracamera1319]

Thank you everybody.

[@olivierfaucher3426]

Shmomp shcams 🤣🤣

[@donm9951]

you should pay extra for hardend flat tappd lobes

[@cuttersperformance]

Never a bad idea

[@benharper1682]

your oil needed zinc! Gibbs racing makes good breakin oil! Flat Tappet cams need zinc to break in.

[@cuttersperformance]

They need ZDDP all the time

[@johnj2496]

And I may be mistaken but Don't most filters themselves have a filter bypass in them as well If they get clogged

[@cuttersperformance]

Most modern engine filters do but alot of older model ones do not

[@parjohansson5598]

❤❤❤❤❤❤

[@ravenrock541]

There is a nation wide issue with all lifters.

[@jims2286]

That is the dumbest thing to do you a small and big block chevys you have to bypass the filter after about 2000 rpm, and the stock oil pump has too much volume. The filter can't handle the volume of oil, so you are starving the engine !!!

[@cuttersperformance]

We do this on all our engines including a 10 000 RPM super stock motor. We haven't had a starvation issue

[@242bleek]

It doesn't bypass at all unless the filter is clogged. You really think oil only gets filtered under 2k rpm?

[@rickyfulks889]

Go roller
