Denis:  One, I am suprised that you haven't talk to your brother-in-law; you 
know the one, the VW engine guru who you sold the blue bus to at an exorbinant 
price to.  Two;  that said, the 90.4s should be fine.  Walls are not too thin.  
That should bring you up to something right around 2000cc.  I assume from what 
you said about the 88s that your case is already machined for the larger jugs.  
If you have that many miles on that engine it is probably time for a freshening 
anyway.  Do a valve job, put in new jugs and pistons and replace the rod 
bearings while you are at it.  You can do all of that without splitting the 
case.

Thanks! It told me I actually have a 1906, although there is some wiggle with 
deck height. 
 
This all came up because, while I have controlled most of it, my engine is 
still blowing oil. My local Porsche/Farrari type mechanic that owns the local 
parts house, says that I need rings because I have excessive case pressure. I 
can vent the valve covers and put in a breather box, but the guy says that I am 
not solving the problem. Derrick at Wayout (also an excellent repair shop) 
tells me he has 90.4 MM cylinder set that will fit right in where my 88s go 
with no machining. The 90.4s have thin walls, problem? My 88s have thick walls.
 
Do I do the rings on the 88s? Put in new 90.4s? Vent the valve covers?

Do a google search for vw engine displacement chart.

There's a good chart that comes from a dune buggy place.

I cannot remember how to figure engine size. I supposedly have a 1904. When I 
had it built 9 or 10 years ago I was told it was a 1914. It is  74.8 x 88. If I 
just multiply that I get 6582.4 which would mean I have a 6 ½ liter engine and 
I am pretty sure that is wrong. How do I get to 1914?
