I have a couple questions, and yes, I did search the forum first
My compression tested at 275psi and was consistant across all cylinders. My mechanic said this wasn't bad, but not great. Said the rings are probably worn.
First of all, is 275 a fairly average compression for a 300TD with 175k miles? If I was to correct this in the future, would it require a complete rebuild, or could I just have the cylinders bored and new rings installed? Has anybody had this done, and if so, what was the ballpark cost?
Thanks, this forum has been a lifesaver.
