Although I doubt this is related to your oil leak, but you still should be running 10W30 as per Toyota's specifications. The correct, permanent fix to the PCV-oil problem is the installation of a catch-can.

Generally speaking, they suck. They usually don't come with piping, mounting brackets, couplers, clamps or a warranty.

It's a very simple system. There are two breathers - one with a PCV valve on the left side valve cover (attached to the intake plenum), and another on the right side valve cover. There are also two hoses going between the two valve covers. That's it. What kind of diagram were you looking for?

Afaik, there is no haynes manual for the Mkiv Supra Turbo. You can see either the left (intake) or right (exhaust) pcv breather port in a few of the diagrams of the Toyota Supra Repair Manual.

Put it in-line with the only hose coming off the outside of the right hand (exhaust) side valve cover.

Are all of the cylinders EXACTLY 150psi? That's very unusual...are you sure you did the compression test properly?

If the plugs are oily, you need to replace the valve/cam cover gaskets and the grommets on all of the bolts and studs that hold the valve/cam covers down, according to the steps in the TSRM. This problem has nothing to do with oil in the intercooler.

the psi varied from 149 to 152 i ordered the gaskets and the pcv valve, thought id replace it while i have covers off i'll let you know how it goes. i got a new blitz intercooler dont know weather to put it on yet or not last thing i want is to mess it up with excess oil running into it . dont mean to annoy you i know this is mickey mouse stuff to you thanks again

Ime, those numbers are a bit low (depending on exactly how you did the compression test, and the calibration of your gauge)...which could mean a slightly elevated amount of blowby. How many miles are on your engine? Has it always had regular oil changes with full synthetic motor oil?

Again, I'd suggest you install a catch-can and see if that reduces the oil in the intercooler pipes.

No problem at all. I'm happy to help if I can.
