I've heard a little bit about O-ring on the engine to contain higher pressures with more boost and all. how much does a job like that cost, and is that something I could do myself? How much for just the parts and how much to have someone else do it?<br><br>-SFB

 

$2-300 not including the head R&amp;R. You wouldn't be able to do it yourself uless you could find a tool to rent or borrow. <br><br>Try here to buy the tool.<br>http://www.performancediesel.net/Hea...ad_o-ring.html
