Turbo Feed Oil Leak

[architechnik]

I've had an oil leak for some time, but it's not where I expected it from. I thought it was from a small gap in the oil return passage along the head gasket, as the oil appeared on the gasket overlap by the front passenger side of the head.

It turns out that it was from the oil feed line, so I added a little torque to make sure it was tight, but it just seemed to keep turning. I figured the head was stripped, so today I was prepared to retap the threads and try again.

When I removed the bolt I found this:

Does anyone have an idea of how this would happen? I have another 1g that I stole the bolt from for now, but that bolt has a tapered end. I'll have another one on order, but I think I'll order one for the other to make sure it's the same bolt as the one I stole.

Simple....it's a hollow bolt. You can't over-torque it or it will stretch and eventually break.

Well, it ended up costing $22 from the dealership. I'll go ahead and post the part number later on for anyone doing a search and needing that number.

That sucks. I just bought (5) of them from Extreme PSi just to have on stock at the shop....$8.13 a piece.

Aw, that sucks. I'm not even trying to go the the mitsu dealer here anymore. They're such a ripoff on so many levels.

is this a common problem for our model years? or for 4g63's in particular?

It's a problem that will pop up any time you over-torque a hollow bolt no matter what car it's on.
