Wolfsburg West Oil Vapor Baffle - any thoughts?

[72alpinewhitebus]

Hi Folks,
I'm trying to reconcile copious amounts of oil in the engine bay coming from the tower/filler neck area. I've got a new tower seal and filler seal, but also got one of these "oil vapor baffle" things from Wolfsburg West. Is it only for restricting vapor or will it also limit oil blow-by as well?

If not I guess I'll be a guinea pig.

It's designed to collect the oil vapour particles in the engines blow by and direct it back to the sump. If you're seeing that much oil at the top of the generator tower then it's worth doing a leak down test to see if your rings aren't worn out

It's a repro of an actual VW accessory to address mild blow by problems. It's not meant to compensate for massive blow by.

I’ve installed few of these on preA two piece engines with good results. Required a bit of trimming and bending to fit correctly.

There is a gasket under the generator. Cant remember if it is open into the case below.

I have a sheet of cork gasket a couple of millimetres thick I use for this. I cut it to fit and coat the underside with aviation form-a-gasket. It is a good deal thicker than stock but the engines I build never leak from under the generator. Mostly they leak from the fuel pump and oil pump. Someday I hope to build an engine that doesn't leak.

Thank you sealant or no sealant was gonna be another question...

Seems to fit nicely. No instructions though so I'm just winging it.

When I bought mine from WW, it came with a template to bend it properly.

The exact shape isn’t critical. It should help, but a good gasket with aviation sealant will fix the leak. I use yellow 3M, but both will work.

If you have worked on this engine before (and stand a chance of not pulling a head stud) you should re-ring the pistons. Dirt cheap, will fix your excessive blow by problem, and will give you more ponies to play with. It is definitely a band aid until the next rebuild.

[72alpinewhitebus]

This is something I'm pondering, and a worthwhile recommendation I totally acknowledge. This all started with just replacing the muffler, so I'm still processing how far its gone. My compression is 95/90/105/95, so I know she's on her last days before a total rebuild. I may be naïve but she runs really well and I'm hoping to roll around for awhile as is. The evidence I've found is that all my oil leaks can be accounted for and reconciled without cracking the case or pulling the heads. If nothing else I'll by process of elimination have everything else done before going internal on the engine.

I used to re-ring engines...but I found that an older engine with a lot of miles on them, install new rings and increased compression took a quick toll on the main bearings and wiped them out pretty quick. Best to do it all at once in my opinion.

Agree with the above from both logic and experience. True even more so, with a 36 hp engine.

I'm doing a refresh on a 36er right now. As prescribed, new mains and rod bearings and reground camshaft to go with new piston rings. Right now I'm wondering how to measure the valve guides to see if any need replacing. When I took it apart, it was quite a bit down in power and a mechanic friend suggested intake valve guides might be worn.

After taking a short course on the University of Youtube I now know what I will do.
