Thanks for the advice. The person who gave me the car drove it for almost 2 hours at highway speed after valve seats dropped so head and motor are toast. The motor i'm looking at is coming out of a 2002 write off. It has a 126000 kms on it and the cylinder commpressions on all four are between 181 and 188. Should i look at taking the head off it and get the vlaves redone before i run the engine. I also was unsure if these were good compression readings. Any advice is welcomed.
