  1. Re: How not to grease the rear slip yoke on a Previa Alltrac

    To add to this, if you add that much grease it's far from the end of the world but it's not good drive with the shaft extended like that. The good news is even if you do, it'll expel the surplus...

    Re: RPM-gauge wiring? 1995 liteace, 4yec

    The gauge should include directions on where to wire it to the coil. OBD1 Toyotas are handy that they have an ignition signal at the diagnostics connector (Ig-) I've used that with success in the...

    Re: differential questions

    Usually coil springs and control arms vs leaf springs requires different mounts on the axles. that means grinding and welding. that means complete disassembly not plug n play.
  4. Re: Little to no rear brakes; proportioner valve delete?

    I did delete the LSPV on my Toyota Pickup due to rust. Ran a manual prop valve and new lines from the master to every wheel. You can't delete just the valve, you have to rerun all the lines. Even...

  7. Re: early (1991-93) vs. later (1994-95) JDM engines

    Use your old fuel injectors and ECM. the SC engine itself (block, head, internals) are close enough to run in place of your FE. the cams are slightly different (no overlap), rotating assembly is...

    Re: No Spark

    If the CEL came on, the first step is to pull the code. I suspect you'll have a distributor-pickup related code. no pickup signal = no signal to the igniter to spark. if you have a scope you can...

  14. Re: Load Sensing Proportioning Valve and Bypass Valve ???

  19. Re: How concerned should I be about the radiator cracking (pic included)

    OAT, HOAT, and the others offer longer service intervals as the biggest benefit (life-of-the-warranty fill) and the additive packages are better for Fe/Al and all-Al engines.
