    Vacuum help needed

    A common question. Somebody really needs to fix that diagram. It goes up past the head and connects to the compressor bypass valve via the metal line that runs across the 3000 pipe. There should be a short piece of tubing mounted to the head that it connects to.

    What type of gasket is this??

    Ah, I see. The hole. Well, been a long time since I've seen that one even though I have a full set of turbo gaskets around here someplace. Perhaps as Mike suggested, an aftermarket one for the same application. If not I stand corrected. And it's been like 13 years. Cut me some slack eh? I did...

    What's the little hole in the bottom of the water pump?

    ^ This. Most pumps have what's called a face seal. It's a spring loaded bit that forces one critically machined surface (typically made from ceramic or carbon) against another. When that interface wears to the point of leakage the fluid will weep out the hole. A face seal can be replaced but...

    most commonly used tools on supra

    In 22 years the car never failed me. Not once. Only things I carried were a good flashlight and a halon extinguisher. It's all about maintenance. Now if you're asking about tools for that it's a totally different story...

    blown mhg? need to fix? how to:

    :shrug: Mine never blew it's HG and those that do don't seem to have anything to do with gasket brand. I'm not disputing what you've seen but your sample rate is tiny. The collective experience of the community indicates you're wrong.

    blown mhg? need to fix? how to:

    Crack me up. I remember when there were no MHGs. We'd use stainless steel wire to seal the cylinders. Now we're arguing about what works...

    Controlling large Injectors (720cc)

    As long as the system is balanced the stock ECU will run those injectors just fine. That doesn't make sense...

    Oil Light

    That's what happens when I break my rule about dealing with swaps and unknown wiring. I should have asked if the flashing was rhythmic, rpm dependent, or just....flashing. Who knows what the light was connecting to. It may have been simply an intermittent short to ground as IJ suggested. If...

    Oil Light

    You're confused. He transplanted a GTE into a Cressida which may only have an oil light that ended up connected to the GTE sending unit. Or maybe I'm the one confused...

    Oil Light

    The stock oil pressure gage is a bimetallic servo type. Picture a circuit where 12 volts comes from the ignition switch then goes through a little heater coil that's wrapped around a bimetal strip in the gage. As you may know bimetal is a sandwich of two metals with differing coefficients of...

    Oil Light

    Well, it's normal in this case. Not very useful though. A stock GTE sender outputs a pulsing ground with a frequency based on pressure. It's designed like that to communicate with the ECU. It's not a pressure switch in the typical sense. If you want a warning light for low oil pressure you'll...

    1) How do you know the charging system is working? State your test method. 2) If you have a flooded cell battery what is the electrolyte specific gravity before cranking? 3) What is battery voltage before cranking? 4) What is battery voltage during cranking attempts? 5) What is the...
