New mk3 trying to learn a bit

Its normal psi till it gets warm and then it'll drop pressure and shut off.

El Supracabras · 07-30-2011, 01:48 PM

So the car wont idle when warm? The oil pressure drops when it is stalling from an idle? Your oil pressure is not causing your car to shut off, your car shutting off is causing your oil pressure drop. Sounds like when it goes into closed loop its not idling.
Time to check for codes. Welcome to the "what the kcuf is wrong with my car now??" game. Round one.

Lol... how do I go about checking my codes? If I put breathers where the holes are, do you think that it'd work or do you think it'd be best to get the vacuum lines that go to the intake? Also I'm getting white smoke on the turbo where the oil line meets. Almost like there's a leak but I'm not seeing a leak unless its on the motor side. Also, my intercooler boot came off. Idk how long its been like that. Today is my first day to really inspect the car for myself.

I'm getting oil in my intercooling pipe.

The way the ct26 is put together, the bearings and seals, even when brand new, tend to leak oil into the intercooler piping, eventually letting the oil rest in the intercooler. Use gasoline and clean it all out. rince the piping and intercooler off afterwards and reattach to the car. Good luck.

Ps. I almost painted my intake manifold black... Now that i see the end result, im happy i did'nt!!!

Thanks. Will do? How do I tell if I have a CT26? It says a/r .70.

El Supracabras · 07-30-2011, 05:33 PM

That's no ct26.
Checking codes is in the faq section.
Breathers would be better than nothing but a nice functional catch can setup would be ideal.
Oil leaking from that line on top of your turbo will burn off quickly so it may not look like it's leaking. Make sure that fitting is tight. While you're at it make sure ALL the fittings and hoses are tight.
A leaking intercoler pipe will cause the car to run like crap, fix it.
Oil in the intercooler is not uncommon but excessive oil in the intercooler might mean the turbo is about to check out.
Keep at it, it gets worse before it gets better but after some time, research and money it will get better.

man I see mods and relocates galore.. Your best bet is to park it. strip it and put it back together piece by piece, going over it with a fine tooth comb, fixing, cleaning and sorting inch by inch. looks like some ebay parts made their way into your engine bay. While there's nothing wrong with that, looks as tho he got in a hurry and didn't really care what it looked like in there.
oh a word of advice, before you go unhooking wires...mark them, for the love of god. put tape on the wires and write it down on a piece of paper or something so you know were that guy had them.

El Supracabras · 08-02-2011, 12:09 PM

You still haven't posted the actual oil pressure you are getting. I would highly recommend sorting out the wiring and vacuum line disaster and performing a few basic engine health tests before doing anything drastic. As Green said, it looks like someone was in a hurry and just didn't care about the outcome. It may be well worth it to take some time, learn what everything is and start cleaning it up. Start on one side of the engine and work your way around.
Check you're actual oil pressure before tearing into the engine.

Looking at your pictures and reading that an IC pipe boot came off, you have numerous entry points for dirt, into your engine.
You may very well have a dusted engine which will account for the loss of engine oil pressure.
A turbo in good condition will not leak oil past the seals. The stock PCV system for the 7MGTE, routes the vented gas into the intake, which carries oil vapor and will coat the IC and pipes with oil.
Since your PCV plumbing has been removed, oil currently is not being dumped into your IC by the PCV.
Your turdo seals could be shot and allowing engine oil into the compressor section of the turbo and being pushed into the IC system.
