Mark Humble Posted October 21, 2005 Share Posted October 21, 2005 Are all EA82 heads cracked? Every head I have looked at has been cracked between the seats. They don't leak into the water jacket. Ok to run? Mark Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted October 21, 2005 Share Posted October 21, 2005 9 times out of 10 the crack won't affect the head, all the ones i've pulled were cracked and still worked great. Quote Link to comment Share on other sites More sharing options...
Snowman Posted October 21, 2005 Share Posted October 21, 2005 There was a TSB released saying that bridge cracks are normal and don't affect the running of the engine. If it's been severely overheated, or you can see that the cracks obviously extend into either port, that's a problem. Otherwise, use a small punch to tap the cracked portion down a bit (prevents detonation) and run them. Quote Link to comment Share on other sites More sharing options...
soobscript Posted October 21, 2005 Share Posted October 21, 2005 Just had mine professionally checked, pressure test. No leaking from the crack between valves. There was a TSB too. No problem unless the crack is 1.2mm wide IIRC (which is HUGE). Just pulled some Gen3 heads from the yard with only one tiny crack on the #3 cylinder (closest to turbo).
