twhb Posted May 7, 2011 Share Posted May 7, 2011 (edited) I had a valve grind on .the right (cylinder 1 and 3) on my 86 xt turbo (EA82). The #1 intake valve was not seating properly. After reinstalling and puttting in the coolant water, it leaked out of a hole on the rear (head is on right). The hole is manufactured as I have another one that has the same holes, but this now leaks water. I guess, I will have to remove this head again and send it back to the machine shop. But I would like to know what is happening. Edited May 7, 2011 by twhb Quote Link to comment Share on other sites More sharing options...
nipper Posted May 7, 2011 Share Posted May 7, 2011 is it a hole or a plug? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted May 7, 2011 Share Posted May 7, 2011 you probably just need to install a bolt in the hole. it's right at the corner/edge of the head right? i think i know which one you're talking about. if i was home i'd walk out to my garage and check but from memory there are holes that are plugged with a bolt on top of the heads. maybe it was removed and just needs reinstalled? if it's a threaded hole then plug it up with a bolt. can you post a picture of it?

MilesFox Posted May 7, 2011 Share Posted May 7, 2011 There is a drain plug on the driver side head. Perhaps it was removed for machining. This is the same hole on the driver side head that the turbo water pipe goes to. Quote Link to comment Share on other sites More sharing options...

scorpiankill Posted April 9, 2019 Share Posted April 9, 2019 I know this is an old post but I think I have the same leak. Is it two threaded holes that are 90 degrees from each other? In the back upper corner of the head? Quote Link to comment Share on other sites More sharing options...
