idosubaru Posted January 28, 2009 Share Posted January 28, 2009 yours might still be good? if you see a crack between the valves seats, that's not a call to get a new head. that's common, more often than not all EA82's and ER27's have those cracks between the valves. more info on the forum here if that's the case for you. good luck.

silo118 Posted January 28, 2009 Author Share Posted January 28, 2009 thanx, thats were they are cracked i have 4 pairs but they are all cracked i didn't think that it is a problem but it is nice to have some reasuance. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 28, 2009 Share Posted January 28, 2009 if that's all that's wrong with them, then they are fine to use. just have a machine shop pressure test them to be sure. (all machine shops do that if you're not familiar with it). don't let them tell you "this head is scrap".....if they're not familiar with these subaru heads they probably won't know any better. the shop i deal with freaks out when i bring them in to get milled. i just ignore them. it's no surprise these things are old and outta the minds of most folks by now.

bigo1966 Posted January 28, 2009 Share Posted January 28, 2009 I have a pair that are still on a good running motor. Im parting it out in the for sale section. Quote Link to comment Share on other sites More sharing options...
Svengouli7 Posted January 29, 2009 Share Posted January 29, 2009 Hi there. I have a pair here in the tri cities but like the 4 you've got they have the small crack between valves. I would just get them resurfaced and think about a valve grind if you can afford it.. or just clean the valves up and lap them in.. Quote Link to comment Share on other sites More sharing options...
88RxTuner Posted January 29, 2009 Share Posted January 29, 2009 +1 on having them pressure checked... you never do know... I had 2 SPFI engines like this, both ran perfectly after assembled. The MPFI cyl heads do the same thing. I never used a machine shop... We always used to block the heads and sand them with a flatboard using 120 then 200 grit sandpaper. Never had a single problem, and I still know some of my customers that I did the engines 5, 6 years ago... Quote Link to comment Share on other sites More sharing options...
silo118 Posted January 30, 2009 Author Share Posted January 30, 2009 yeah i deal with local machine shop everyday, its nice i can get quite a discount. Subarus are kinda a new thing to me ive only built 4 ea82s and 2ea81 turbos, its just that most customers don't want cracked heads no matter what i said about they will be fine they want not cracked ones the i explain the price of having them welded and they ************ there pants lol its a loose, loose situation Quote Link to comment Share on other sites More sharing options...
88RxTuner Posted January 30, 2009 Share Posted January 30, 2009 Subaru themselves actually released a TSB.. Technical Service Bulletin.. relating to this precise problem. Subaru states that so long as the cracks are limited to the area between the valves (web material) and do not show evidence of coolant leakage indicated by white buildup or abnormally clean areas around said cracks, that the heads are in perfectly functional shape and should not be replaced...
