Looking at an 05 with manual transmission. It has 169000 miles on it and some blow by . How big of a deal breaker is that? Also I would like to have the cylinder compression checked . What is the range I should be looking for in as far as compression goes and what amount of compression would be not adequate?

 

Put the oil cap on the hole if it blows off walk away it needs a rebuild. Compression I think is around 500 but you'll have to look that one up!
