Is there anything you can do If you strip out a head bolt in an EA82T. Me and my buddy Jordan went to replace the head gaskets on His EA82T and 3 of the head bolts just spin, 2 on one side and 1 on the other. I think that this is what made the HG blow in the first place. It looks like someone has replaced the HG's possibly before, and the water pump, but while tightening the head bolts they stipped them causing them just to blow again. I would like to know if any one else has found a way to fix this issue, let me know if you have!!!

Well... I Didn`t Understand clearly your Question... but I Hope this can Help You:

Good Luck!

HeliCoil is the best way I know of. You can get them at most any parts store. It's similar to the posting using the bolt but easier. You'll get a drill, tap and helicoils in the kit. I'd use hi-temp loctie on the helicoils just to make sure they're stable.

While I agree with the use of helicoil, i would have a tendency to take the engine out and dump it at a machine shop, letting them take care of it. They've fixed many more of these sorts of things than any of us have. The price of them doing the work will be less than the price of you doing it wrong and having to replace the engine.

 

I feel pretty confident about my abilities, and I've installed helicoil dozens of times, and I'd still rather have a machine shop do this on such a critical fastener. Just sayin'.

are you having a problem getting the bolt out too? if so try and get something underneath of the bolt head...like a screwdriver, chisel or pry bar. of course taking care not to damage the head. pry upward on the bolt while simultaneously loosening the bolt, this should get it to come out. helps to have help doing this.

 

once it's out there's not too many options. i'm a fan of having a machine shop do something like this as well and i've done that before, have them fix a block.

 

but other than an insert the only other option i can imagine is to use a slightly larger diameter bolt...maybe a standard threaded bolt would probably work. use a bolt or locktite a stud into the block for the head if this is a last ditch effort.

 

i'd probably just tap the holes with a different and slightly larger thread, like a standard thread. that will slightly change the clamping force characteristics but considering the standard usmb practice of using Fel-Pro permatorque gaskets and adding extra pounds to the final torque i wouldn't worry about it.

Timesert is better than heli-coil for this application. Either one would most likely work, but the timesert is a much higher quality device.

Better off finding a new block. A good old Carbed block can be got for next to nothing. Probably less likely to have been abused.

 

Swap you're pistons and you're set with what will likely be a better bottom end.

All the bolts came out just fine, they didn't feel like they was anything wrong with the threads but......

Jordan and I have decided to start from scrach so we bought audio files EA82T. I just think that would be the best for right now it needs to be running by monday or tuesday Afternoon, so This is just quicker. I'll need all this info for later. We will be rebuilding it sooner or later. Thank you for all the help. I'm sure you'll see this thread come up again sooner or later.

HEY!! this gives us a great excuse to re-tap the block to take a size stud that the aftermarket world actually builds!!! then we can run up the boooost to like 20psi (for a minute bfore it goes booooom )

 

lesss doooeeeeet!

Sounds good to me but We'll have to talk Jordan into it.

i think im gonna have this problem when i put my heads back on. my dad has used heli coil on his subi and no know ill effects so i'll prolly do the same

I agree those look much more rugged than helicoils. Must be good for other heavy duty uses also. Once the head is bolted down there's no where for the inserts to go anyway, but knowing that the bolt is held in by those would make me feel better.

Either timeserts or helicoil. I would personally never consider simply tapping for a different sized fastener on such a critical application.
