    New Heater Valve Replacement Options???

    Maybe where your from. But when it’s 80-100f out even new Toyota’s it can be hard to reach that unless you run it for a long time. Although you can run into evaporator freezing. Usually I would see 45-50 more common.

    Leak down tester

    you want like 5-10% leakage max. a healthy engine is usually 2-5%. if air comes out the radiator cap then hg is blown. I have a snap on one so not sure about the others, but like a otc one should be fine. any really should be ok.

    JZX90 cluster help

    Ya so the location of the plugs are not relevant to what there going to. You might be able to get lucky and go to junk yard and other Toyota’s would fit. Which is usually the case for similar generation Toyota’s. As there is not only the gauges but all the lights and dummy lights. The tach...

    so water temp will be the single wire temp sensor on the water neck, oil pressure comes from the sensor, rpm will come from the ecu, and fuel level will normally be on the body harness. regarding the cluster wiring you can easily take apart the cluster and read the circuit board and trace the...

    If staying stock egr isn’t really a bad thing to have. It’s only active during cruise. For stock ecu the cold start injector would prolly have better start up drive ability if the ecu your using is looking for it. The trac stuff you can delete. The throttle if you use a non actuated...

    Oil squirters... Keep or Delete???

    New engine smokes on decel

    that shouldnt damage the turbo. but if you siliconed the oil drain flanges on its likely that its blocking the flow pushing oil out of the turbo. also you can pull the valve cover breather tube off and idle the car and see if smoke comes out the valve covers. if a lot does its blow by.
