X35 Performance Posted May 29, 2004 Share Posted May 29, 2004 I just pulled the heads off of an EA82T recently and snapped one head bolt on each bank. The other bolts came out very corroded, but the threads are ok/cleanable. I retapped the 2 offending holes in the block, as there was no way the remainder of the headbolts would come out. I'm wondering if this is a common problem? I'm heading out to near Seattle in about 2 weeks to pick up another XT turbo with a bad head gasket (thanks to whoever posted the link to it in the marketplace ) I'm planning to pull the head and put it back together so I can drive it home, but I'm a little worried about either snapping a bolt, or stripping out the thread in the block, as if that happens then I'm totally screwed and will have to pull the whole motor to repair the threads. So....just how likely is it that I'll be able to pull the head successfully. It's the RH head on a 86 XT turbo. Not sure if it has ever been pulled before. Also, is there any chance to repair the thread with the engine in the car? Doesn't look like too much room to work... Thanks for the continuing wisdom.

rallyruss Posted May 29, 2004 Share Posted May 29, 2004 never saw one snap yet but any thing is possible. pulling the motor is usually a better option than an in car job. Link to comment Share on other sites More sharing options...
JWX Posted May 29, 2004 Share Posted May 29, 2004 ya I wouldn't try in in car. I would either tow it home or get it transported Link to comment Share on other sites More sharing options...
subarubrat Posted May 29, 2004 Share Posted May 29, 2004 It happens on ER27 engines and they are a close relative of the EA82. They also like to suddenly strip and spin free just as they reach the specified tourqe. Link to comment Share on other sites More sharing options...
rallyruss Posted May 29, 2004 Share Posted May 29, 2004 ok so let me just do a little related hi jack. I recently tried to order cyl. head studs from ARP. and due to my own stupidity I ordered them in 10 by 1.25 when they are actually 11 by 1.25. Doh. of course they dont make both the long and short sizes to fit 11 by 1.25. I think they did have the short ones. so if any one has a source for head studs or we get enough interest to get ARP to make some up special. (they do that too) It would be a great alternative to head bolts in an aluminum block.(there see its kinda related) Link to comment Share on other sites More sharing options...
Marck Posted May 29, 2004 Share Posted May 29, 2004 I am interested to get some ARP studs. What do they cost? Link to comment Share on other sites More sharing options...
rallyruss Posted May 29, 2004 Share Posted May 29, 2004 well the 10x1.25 studs, nuts, and washers ran almost 200 with shiping. not cheap at all. but they are far superior in quality. my only other thought is to find em in 7/16 fine thread and helicoil the case. not the best idea as its easy to go wrong in the instalation of 18 helicoils.
