gravelRX Posted January 26, 2004 Author Share Posted January 26, 2004 I just took the heads off tonight. Haven't cleaned them or anything. the cylinder bores on all the pistons looks good. I'm concerned about the cracks though. Jay Quote Link to comment Share on other sites More sharing options...
GLCraig Posted January 26, 2004 Share Posted January 26, 2004 Don’t worrie about those cracks; it's real common to see those on an EA82. There's also a service bulletin that addresses the crack between the valves. Here’s a pdf copy. http://home.comcast.net/~c.moe/heads.pdf Quote Link to comment Share on other sites More sharing options...

electryc_monk Posted January 26, 2004 Share Posted January 26, 2004 clean it up and prep it for return to service dude! Quote Link to comment Share on other sites More sharing options...
toybuilder Posted January 26, 2004 Share Posted January 26, 2004 Those cracks look fine, I've used worse. Gen 3 heads really only addressed the issue of cracking where the exhaust runners come together. If you are putting new rings in, make sure you give it a fresh hone. Even though you can still see the original cross hatch, it won't have enough bite to properly seat the rings. Good luck. Quote Link to comment Share on other sites More sharing options...
RedLance Posted March 20, 2004 Share Posted March 20, 2004 Out of curiosity, how many miles were on this block? My EA82T had 167,000 on it, and still had those cross hatching marks... Quote Link to comment Share on other sites More sharing options...

gravelRX Posted March 21, 2004 Author Share Posted March 21, 2004 or around about that. I didn't know what to expect, but the cylinders walls being what they are, I was pleasantly surprised. Makes me feel better about rebuilding the top end. Jay Quote Link to comment Share on other sites More sharing options...
