Project Thread Seal on the back of left side of motor?

[ihiryu]

So I boosted my MKIII Supra, with a Holset HX35 running five psi currently, and I popped out the rear cap deal on the valve cover.

I went ahead and used Honda Ultra Flange II (what they use for valve cover, really strong stuff) and it seems like it's holding fine. However I know this is going to be an issue later on down the road.

Has anyone else had this problem?

Yes,

Your setup is wrong and too much crank pressure. Check your routings.

Yep your possibly boosting / pressurising your crankcase..
Check crankcase ventilation hoses??
Especially from throttle body to cam covers...
It needs to be separated and attached to turbo inlet side via oil separator..
Check PCV is holding boost pressure as well ?

Yup, I put in a Supra TT PCV valve in place of the stock one with an oil catch can. I didn't realize it until after the first maiden voyage (actually the fact that it's been sitting for a year and I couldn't help but be giddy like a little girl on her first date).

So I went ahead and bought a supra TT PCV, and installed the catch can, I'm going to do some driving tonight and see if it fixes the problem.

I had an idea that I was pressurizing the crank case cause I got a good amount of blow by, but the compression came out good.

Like XR said, check your outlet under the TB. Is should be close off.
