    Red line 75W-90 already has the friction modifier in it's formulation...it does not need any additional. If you use Red Line 75W-90NS, you will need the modifier and can "custom add" to suit your LSD. A note on using Red Line...on some high mileage, worn LSD's it *can* induce clatter. It's...

    Charcoal Canister?

    http://www.cygnusx1.net/supra/Library/TSRM/MK3/manual.aspx?Section=EC&P=6 A better way to put it is the gas cap is not vented to the atmosphere. If you look at the above link, there is a check valve in the cap that allows air into the tank under vacuum. Fuel vapor is flowed into the...

    Charcoal Canister?

    Giter - there is zero reason not to have a charcoal canister installed. Red - it is irrelevant what other vehicles do or what happens at the pump as far as emissions goes. What you're saying is "everyone else pisses in the street, then I should too". And, BTW...the Mk III does not have a...

    Trying to Solve Fuel cut - at wits end - this one will stump you

    Under the ISCV there is a disk with "spokes" on it...looks like a little mag wheel. It's a check valve, the "spoke" side should be seen when the ISCV is removed. Make sure the ISCV gaskets are good. These can get blocked open with carbon or just get old. This too is a bit of a...

    Trying to Solve Fuel cut - at wits end - this one will stump you

    Nick is correct. Fuel cut is a direct function of the AFM and the volume of air it senses being flowed to the motor. The FPR, J tube, injector size, etc has nothing to do when the motor hits it, and a code 34 will be set when it does...however, fuel can determine a rich AFR condition. Hitting...

    Changing oil every 3k miles. Are people wasting money?

    Matt - This SAE paper explains it: It's really simple...the oil change places out there make $$$ by you coming in every 2 months. Any decent dino oil will go 5000 miles. A PAO or ester based synthetic, 8000 miles easy (just change the filter at 4K). If you do analysis, you can go even longer...

    transmission fluid recommendation

    The same applies to a high mileage LSD...Red Line can induce "clatter". That's why I'll tell guys to give the Ford 75W-90 a try...you can use it in the tranny too, just don't use the friction modifier. In either case you are running on borrowed time. Using a conventional gear oil may make a...

    Car starts, but rough idle and white smoke

    Not if you understand how it works ;) In this case, setting the initial timing is going to get you close.

    Charcoal Canister?

    Wait...what?!?! That will turn the catch can into a bomb...the charcoal canister has charcoal in it for a reason! Geez...just do as IJ suggested and put a JDM canister in the fender well. This getto rigging is going to get you into a lot of trouble!

    Vent the cap and you lose the positive pressure the tank was designed for ;)
