Thanks a ton! This series of videos helped me visualize everything that the books talk about.

We used to use a small piece of 2 X 4 wood and a Hammer.And cover it with a rag in between the seal and the wood.Then hit it with a hammer.It will sit flush with the case.I don't remember having to recess the seal.Brings back memories from back in the day in So-Cal .Thanks for taking the time to post.

Cool thanks for your educational video there very helpful for me being a hobbyist

[@dwightgeorgecarlson]

Other than the convention of Front versus Rear designation, you videos are Excellent. Thanks for going to the work of producing and up loading them.

[@DragRacingTV]

+DG Carlson thx for the feedback, appreciate it.

I been doing VW aircool for some 45 years. Still after all those years everytime I build an engine. I enjoy it like it was my first time rebuild a VW engine. Sealer is good on every signal oil leak point. Must use the correct sealer and the correct way. One more thing you didn't line up the flywheel correct for better balance as well as clutch assembly sometimes it makes a big difference.

[@MrGarcon98]

wow i am curious how ? do you line up a flywheel that is stock ?

[@shaneorndorff452]

Great video

[@larrykeesee1442]

GREAT JOB.

[@dwightgeorgecarlson]

I bought the 'cheap' tool. Gland you pointed out about the dowel interference. I will see if I can drill clearance holes in the tool so I can leave the dowels in place.

Nobody ever mentions that the teeth on the flywheel are machined in as opposed to being a shrunken on starter ring-gear, the flywheel being of hi-quality stee!l

Hello Mike, which is the diameter of the washer that you used to install the oil sealer of flywheel? Thank you!

[@johnmalmeida3668]

THANKS, for good video ,EXCELLENT THANKS

[@DragRacingTV]

+john m almeida thanks for watching, glad to hear that it helped!

[@AWcinema]

Hi Drag racing I love your video, but can I add 2 cents to this video " be careful " adding gasket sealer to the flywheel seal. as you know their is an OIL galley hole just behind the flywheel shims to alow oil to lubricate the shims. and you don't want to take the chance of pushing sealer in to that hole when you drive home the flywheel seal. I hope that helps any one new to building VW motors

[@DragRacingTV]

good tip aw, thx for pointing that out!

[@dwightgeorgecarlson]

John Muir puts the oil pump into it's 'cavity' prior to cinching down any of the case bolts other than hand tight. Do you do it that way or do you just leave the small case bolts/nuts near the oil pump out/untightened until you install the pump? i.e. Tighten the large case nuts fully and then install the pump? Can one do a dry assembly including torquing the large case nuts to check for freedom of movement of the crank and cam and then take apart and apply the sealant and reassemble? i.e. would torquing twice cause any problems such as distorting the bearings?

[@DragRacingTV]

+DG Carlson That sounds similar to what Mike does, you don't want to torque those small nuts around the oil pump all the way down until after you have the pump in there: kzbin.info/www/bejne/gpWwfXlqm9JjlaMm38s Partial short block test assembly and torque down could be helpful in certain circumstances, for instance you did an align-bore on the case, or maybe you weren't able to check for a bent crank because you didn't have access to a test jig, or perhaps it's a performance stroker motor, maybe you are checking main bearing clearance with plastigage, etc... i could see it putting crush on the bearings, but if it all goes back together the same exact way, i'm not seeing a problem? maybe get some other opinions on that. It helps to re-torque all of the case nuts down before the initial teardown of a used short block, and check for free rotation also then, but that won't apply to you because you've got it all torn down already.

Please help, Rebuild 1600 engine. Having problems with oil cooling. I have one split. Replace it and the 2nd one split . It splits on the 2nd day I start the engine. What could the problem be?

[@DragRacingTV]

The oil coolers are splitting? Sounds like a possible oil pressure problem, so maybe pull the oil pressure relief valve out, see if the plunger is binding or sticking in the bore. Also check that the correct spring length is in the bore that it was designed for. Long shot might also be that the oil pressure relief springs are not factory VW, so is the spring tension correct?

[@gregorytimmons4777]

Sounds like oil pressure relief piston stuck in bore. I had this happen on a Peugeot 504 engine i rebuilt at home in the garage. Varnish from oil residue froze the relief piston in the bore. In my case it just blew the oil filter up like a balloon and then shot it off the mount and across the garage floor.

I’m trying to freshen up my 1966cc engine. I recently broke and developed cracks in my cylinder heads and decided to split the case and freshen the bearings , mains,rod and cam. The engine has 92 pistons/cylinders, Rev True Stroker Crank with small block Chevy rods, Racer Brown cam and 1.4 AutoCraft rockers. Mike my concern is the end play which is excessive .085 no shims no seal. The engine has performed flawlessly since it was built by me since mid seventies and always seem to have a lot of play. Prior to damaging the guide bosses the engine never made any noise, my hearing has deteriorated over the years, but I heard nothing abnormal. I was thinking today that this is a 12 volt eng and I run a 6 volt flywheel , it is the eng in my 57 Oval. I’m at whits end and any advise would be greatly appreciated Look forward to hearing from you Thanx Richard

[@richardciviello3817]

Did you take a look at question on crankshaft endplay and 6 volt starter

[@DragRacingTV]

hi richard, mike is unavailable right now, and with that unusual selection of parts the only thing that i can suggest is to first do a case inspection per the videos, don't try to correct that bad end play on a case with a hammered-out center main bearing saddle, for instance... if by some miracle the case is not cracked/worn out, look at the basics, like making sure you are measuring the end play correctly, aka not rocking the flywheel around, is the flywheel nut fully torqued down, etc... i've never run a 6v flywheel, so if it was me i'd be researching what if any the differences are, do you need to mount a 12v flywheel to see if it affects the endplay, etc.

[@richardciviello3817]

@@DragRacingTV thanks for the comeback the flywheel does hop a little when moving back and forth I have measured numerous times with dial indicator, feeler gauge and all the same, no shims seal out flywheel tightened but not torqued to final amount.what should I be looking at with the center main. I do not have a 12 volt flywheel I would have to locate a used one or buy a new one and clutch assembly unless the 12 volt was first introduced in 66/67 it still used a180 clutch. Which video looks at the case and center bearing, again thanks for your reply

QUESTION PLEASE i just damaged a case by removing the fly wheel and reinstalling it without ! seting the end play ! i did not know you had to do that everytime you remove the flywheel ,,,,,,my question is WHY NOT USE THE GROOVED PISTON ON A dual relief case ? and if you do will it cause some change in the oil pressure ? or what ? ,,,,,monday octorber 2020 ,,,,,thank you in advance

[@DragRacingTV]

That's a good question, I wonder if adding the 2nd pressure relief to the dual o/p relief case made it unnecessary? Good luck with that case damage, I hope that you can still use the case.

[@MrGarcon98]

@@DragRacingTV thank you so your not sure as to why ? not to use a GROOVED OIL PISTON ? if you do use a grooved piston will it cause oil pressure drop or anything related to that ? can you refer me to where i can answer that guestion ? please ,,,,

[@DragRacingTV]

@@MrGarcon98 Sorry I don't know why the VW engineers changed the piston design for the dual o.p. case. Maybe try posting that question on a forum? Like this one: www.thesamba.com/vw/forum/viewforum.php?f=12

[@DragRacingTV]

@@MrGarcon98 Used cases are always a gamble! It's a good way to get experience tho, lets hope the next case works out better.

[@dwightgeorgecarlson]

I wish that you would have used the 'John Muir' 'convention' of Front is Front and Rear is Rear. What you call the rear is the fly wheel end and I guess you have carried this over from cars in which the fly wheel is at the rear of the vehicle which is opposite of what is used on the air cooled VW engines.

[@DragRacingTV]

+DG Carlson my opinion is that the flywheel is always at the rear of an engine, because you can't apply the muir convention to a fwd car, that has a transversely-mounted engine... read page 3 of the orange bentley, where it says, quote, the vw 1600 engine, which is installed in the cars covered by this manual, is a four-cycle powerplant, rear-mounted, and air cooled... rear-mounted as in, rear of the engine. but then again, page 39 of the manual might conflict with that, where it talks about the location of the oil pressure valves.

[@gregorytimmons4777]

Makes me wonder how an experienced VW engine builder makes a mistake like that on the oil pressure relief piston.

[@DragRacingTV]

O.k., I see your point there, it's a good thing that we caught it later. It's a pretty common mistake, and I think that showing it makes the video better.
