TheSubaruJunkie Posted March 5, 2004 Share Posted March 5, 2004 Probably just casting marks. I remember seeing the same thing on my EA81, and thought they were cracks. Turns out they werent. -Brian Link to comment Share on other sites More sharing options...
GLCraig Posted March 6, 2004 Share Posted March 6, 2004 cracks between the valves are common on ea82s. The vast majority of the time they are nothing to worrie about. here's a copy of a SOA service bulletin about those cracks. http://home.comcast.net/~c.moe/heads.pdf Link to comment Share on other sites More sharing options...
old sub freak Posted March 6, 2004 Share Posted March 6, 2004 iv'e seen many of those,the ones that are cracked bad will be really clean {preasure wasned w/coolant} iv'e also seen the cracks peened w/ a center punch, to try and fix them??? and the old school test.lay head out side and fill cyinder"head w/gas and time how long it takes to drain out. or not. as i recall if 1/2the gas is still there in 10 min.your good to go. or something like that, the more gas retained the better. good luck todd Link to comment Share on other sites More sharing options...
