advice needed 05 cummins
 

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?

youl be looking at a rebuild soon...blowby is lost compresion ..it will only get worse from here...:td:

A little is normal on these, how much are we talking about? This is not a chevy these motors are known to go a million miles and more.
