HELP!! sparknock on 82 buick 3.8 v6
November 28th, 2009
I have a 82 cutlass with a 3.8 and it has bad sparknock.I was using 87 octane fuel,i have added octane booster it helped but it still has a slight knock.I have also tried 89 and higher octane fuel but it runs the same.I have moved the distributor,to try to solve the prob but it didnt help any.So i have set it were it runs the best.It knocks the worst when its warmed up.Do you have any ideas on what else i can try.THANK YOU….
Your EGR valve is not opening or the ports are clogged.
Happens (Happened???) a lot on the 3.8A carbed Buick engine
Left alone, I’ve seen holes in pistons and much head damage
