Rhoads Lifters On Solid Lifter Cam - Setting Valve Lash

Well said yr
Just the opposite of the comment above I rebuilt a VW waterboxer (never again) and it was burning oil- so much in a 1000 miles-switched to Mobil 1 and it quit- go figure
a couple of new oils are fantastic]\
The new Corvette dexos II (Not dexos I version 2) and the VW 508
Actually Mobil 1 ESP works for both 0-40 for the vette and 0-20 for the VW (there are other weights)
the vw spec works for both gas and the 507 diesel spec
pricy stuff but worth it if you are pushing the envelope
