oil in intercooler
 

i have a 95 twin turbo recently i noticed oil dripping from intercooler would anybody be able to give me any info on this thanks

Most likely it's not an issue (depending on the quantity) and the oil is coming from your PCV system. Worst case you've either got excessive blow-by in one or more of your cylinders or your turbo seal(s) are leaking. I'd suggest starting with a compression test, and also consider routing your PCV hose(s) through a catch-can.

thanks a lot for the reply .I striped front of car today to get a good look at it looks like intercooler got a good bang underneath it at some stage ,i priced a new one from blitz 1400 euro was told i would need a boost controler 800euro if i upgrade intercooler ,thanks again for your help

You don't need a boost controller if you only upgrade the intercooler. Those two modifications are not directly related to each other at all.

in relation to turbo seals are the seals pressed in or can they be removed and refitted easily or do i have to get turbos reconditioned any advise please

You'll need to remove the wheels in order to get to the seals, and you (in theory) could probably replace them yourself. The problem is after you put the wheels back on, if they're not absolutely 100%++++ perfectly back in the same spot, it's possible (even likely) that they'll be out of balance. Since the turbo wheels spin over 100,000 rpm, balance is ultra-critical. It's the balancing step that there's really no way to do at home (afaik)...so in general it's best to send it to a turbo repair shop to have the seals replaced.

i took off and cleaned out intercooler and all pipes definatly need new intercooler but after two days i had a steady leak again iwas talking to turbo dynamics uk and they reckon i have a crank case breather problem i had motul 5w 30 oil in car they think this could hav sumthing to do with it. what you think about intercoolers on ebay? and do you know where i can get diagram on crank case breather. I hav a car graphics and window tint company in Dublin a lot of guys that come into my garage think this oil was start of my trouble .I have full service history with this car it was 100% before i used this oil

I'm glad to hear they agreed. ;)
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?

first of all thanks for all your help ,im not the most mechanicly minded person i was just wondering were to look for breather maybe copy from haynes manual ,but you already answered that question .Igot a cusco catch can just wondering were to put it ,im goin to go ahead and get blitz intercooler on monday

Again, which one?
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.

i done a compresion test on my car all cylinders are 150 psi is this ok ?plugs were a bit oily the cylinder closest to bulkhead was worst

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.

Hi Phil i was just listen to the infamous death whine on mkiv.com that noise has been steadily growing in my car past few weaks ,thats all i need.
still waiting on my gaskets,grommets and catch tank to arrive .
Ive been on mvpmotorsports a bit and i like the look of the PHR stage 1 turbo kit i could just about come up with that sort of cash if need be ,if i did would i get away with just upgrading the fuel pump and fuel pressure reg.?they also mentioned removing mass air flow?
Iwas thinking of changing my rims ,not any more.

You won't need to remove your maf, imo. As long as you keep it below 600rwhp (6spd) you can get by with (only) a fuel pressure regulator upgrade. It's critical that you keep it below this point, even including boost spikes and boost creep (i.e. don't set it for 600rwhp max/average, with peaks up to 625rwhp, for example). Of course, be sure to run a sufficient octane of fuel for the boost level you run it at.

With the aftermarket (adjustable) fpr in place, set base fuel pressure to about 55psi or 60psi, and then reduce fueling 0-3500rpms accordingly (using an AFC, emanage, or map ecu)...and then dyno-tune with care.
