<VV> MOTOR WOES

[N2VZD at aol.com]

I shudder every time I build a motor (especially for someone else) that  
something like that might bite me. So far , I am doing OK. That issue sounds a 
 lot like valve seals not installed , or on  the wrong valves?
This is assuming a lot of other things have been checked , compression ,  
maybe a leakdown test?  (airing up each cylinder , one at a time)  Any  signs 
of oil on the plugs?    only oil issue I had a few years  ago was 
apparently caused by a  local machine shop HONING cylinders out to  .020 , instead of 
boring them. I fixed it with a set of Clarks cylinders to  match the 
pistons . Even though I could not "see" the problem.
My worst funny one was noises caused by pistons marked .030 in new  
cylinders (from out west somewhere) that were really .020. I now measure  
everything I buy , after all the fun I had because I trusted the markings on the  
parts.  ALL 6 were wrong.
