  • Another question I had.. What do you use to seal the case & cylinders, bolts, washers etc?
    I'm using Yamabond on the case halves, thought about using it on the case/jug flange too.
    I see people using RTV, Permatex #3, Gascacinch, Hylomar, Locktite 518, Yamabond, Hondabond...
    Some folks say 'NO' RTV on a VW motor, some say use sparingly.

      • Nah, just healthy banter. She reads most of my stuff sooner or later, so I leave a trail of breadcrumbs. I find that getting myself in trouble is far better than simply wondering what I did wrong. I have a great wife, she can't help it she has no Y chromosome......actually I'm glad she doesn't! That would get weird quickly now wouldn't it!?

        I use Permatex #3 on the case halves only. RTV under the cylinders. And on the bolts studs, I've left them bare and also RTV'd them. On a stock engine with no shuffle pins on the main studs, I think the stock o-rings do the job with no RTV needed. With a shuffle pinned case....well, those pins fit so snug I'm not sure RTV is needed on them either. But I have added it there with no ill effects. Either way, I'm definitely on the "use sparingly" side of the crowd, just enough on the surface to know its there, not a bead at all. Skim coat on both surfaces, slap them together after they barely start to dry.

        The biggest thing I find on leaky VW's is the oil-drain plate. Everyone torques the heck out of those little studs, and when they leak because the plate is warped, they tighten them some more, further warping the plate. I've cured a bunch of those by simply taking the plate off and smashing it back flat with a hammer, even going beyond flat a touch to create a slight "dish" where the bolt holes are, then reinstalling with new dry gaskets and new little copper o-rings on the studs. Tighten just barely in a cross pattern, and stop while you still think its not tight enough. Those are spec'd to INCH-POUNDS, not FOOT-POUNDS, and there isn't much tightness to an inch-pound.....

        That said, I actually own 1 VW that doesn't drip oil. And no, it isn't empty....

          no motor in it? it's like a Harley, it marks its territory (although I've yet to see a harley with a flower pot... that'd almost be as weird as a wife with a Y chromosome - not that there's anything wrong with that).

          • Ha! It actually runs and drives

            Come to think of it, it must be a confused VW....it leaks brake fluid from the front instead of oil from the rear. Must have been scarred as a youth, and is conflicted now.

                • Nice! I need to build one of these for my favorite neighbor harley guy who lights up the straight piped cold natured turd at 4:30a. I don't mind his bagger, but the one with the drag pipes I want to do bad things to. I figure midnight or so with an open headered 302 should do what I'm looking for. I have to be able to make it directional so it points straight at his bedroom like his garage does mine. Needs to be mobile... yeah, that's the ticket. : )

                  • Necessity is the mother of invention. The reground camshaft I got is throwing off the rocker geometry really bad & can't use it. Sooo, I'm selling it & buying a good used or new cam, but I need a set of lifters to go with it.

                    I got these gems out of a really shitty AS-21 German case. They still had plenty of margin on them so I figured wtf, I'll try regrinding them... BY HAND! I used a crappy run of the mill Harbor Freight 6" bench grinder & some heavy grit sandpaper for the final lapped finish. I managed to retain the concentricity on ALL of the lifter faces & they turned out beautiful!

                    I even managed to get a really nice crown on the top of the lifter surfaces, as per suggested by VW. These lifters are 'almost' better than the 'machined' ones I got with the reground cam!

                    I still have to polish the inside & outside of the lifters but other than that they are done. No ones gonna tell me you can't regrind a solid lifter by hand!

                    All of those years working in the machine shop paid off right here. I can pretty much do anything with metal parts because of it.

                    All I need now is a good used or new stock cam, & I'll be slamming the VW motor back together, FINALLY!!!

                    • Very nice work. I'll have to try that someday. I just had a set of lifters "reground" and when I got them back - flat with no crown. Grrrrr.....

                      I just got a pair of "junk" engines the other day. I can see if the cam is useable if you need me to? Its got a rod cap half way thru the top of the case so no guarentees...

                        I kinda surprised myself with those lifters STINEY. I noticed that as long as the lifters have not already been reground, & are all worn fairly evenly you can get away with hand grinding them back to spec. It's time consuming but it pays off big time when you're finished. I'd do a set for you if you wanted.

                        And yes, please check the cams (if they are 3 rivet) in your core motors too, I need a cam!!!

                        • So I said fuggit & spent $120 for a "NEW" cam & lifter set, that is supposed to "WORK" like it should!
                          I figure as long as the rocker geometry is good I don't care, I just want to get this damn thing running.
                          This project has been a money pit, but now I know just about everything there is to know about VW engines.

                          • I wonder if the new lifters will be any better than those you reground yourself?

                            This project reminds me a bit of my F350 - full of expensive surprises!
                            There's always something new to learn.

                              I showed the lifters to a few people & no one could believe I reground them by hand.

                              I asked the sales rep at CB Performance what the country of origin is on the cam/lifters.
                              They said they are OEM Brazilian, which is way better then the China made EMPI crap.
                              I sure as hell don't need this cam to go flat right out of the box!!!

                              • I'm about to break-in the cam on a 2275. Used some special paste on the lifter/cam faces, and more zddp additive in the oil. I'm worried, but there is not much else I can do except cross my fingers. Hopefully we both have good luck!
