[s-cars] When good Dads go bad (and blow your motor)

Tue Jul 8 05:40:07 PDT 2008

Thanks for the words guys. I should have been more specific.. I have another
head in my garage to work with and can hopefully do a weekend swap. I will
definitely replace valve guides,seals, have it decked, likely port&polish,
etc.. Unless I find a great deal on a whole motor I can just transplant,
then have mine to work over top to bottom over a year or so.

What I meant to specifically ask is options for valve springs and maybe
larger valves. Does anybody know what Dahlback uses? Are you guys with over
4/500 HP still on the OE lifters? I already have the rs2 exh. cam.

Ive dealt with dozens of cooked VW/Audi motors in the past and this scenario
typically requires only a reworked head, and though I recognize the
possibility of Toms pessimism :-) I will have to side with Dave for now,
maybe for my own mental sanity..

Are there any good ways of diagnosing the piston rings? Ive only had to
rebuild a handful of bottom ends due to obvious failures.
