    Is MotorCraft GL-5 Gear oil THAT expensive ?

    I am not from the US, and I saw some ads for Motorcraft 75W-140 in my country for a very cheap price. I checked R.A and it is so expensive ! The Lucas is only like 11 bucks. Which leads me to think the Motorcraft sold in my country must be fakes. So for you Americans, is this a normal price for...

    Diff oil to quiet diff whining

    Ok I know what some of you will say, rebuild the diff properly. I did, 7 times, and changed Ring and pinion twice, brand new OEM gearsets. The diff is a IRS mk3 Supra 4.556 ratio , 9 pinion , 41 tooth ring gear. To cut a long story short, I experimented with various pinion depths and pinion...

    New Old Cars TV a channel that deserves more views.

    I stumbled on these guy's videos. A novel idea, review 80s and 90s cars as if we were back in those years, seeing it from a perspective of that year . So far he has reviewed 3 cars only. I think what is holding him back is he needs to buy those cars then review them. I think many owners might...

    Here is a translated article from Motor Fan Japan on an experimental 2 stroke engine using the 7M block and a 4 cyl diesel block. The diesel version was installed in a Z20 Toyota Soarer, which is related to a Mk3 Supra. It was displayed at the 1989 Tokyo Motor Show.

    Could brake cleaner be absorbed through the skin

    I was doing some work on my differential, spraying brake cleaner on the diff cover, while holding it. It was a continious 1 minute plus spraying. This morning I woke up feeling a little weak with a general feeling of malaise. I just wonder if it was the brake cleaner absorbed through my skin.

    Breaking in new Ring Pinion, GL-4 or GL-5 ?

    So this got me thinking, why not use GL-4 oil in the break in period, since it has less EP additives, to generate a bit more initial wear ? Anything wrong with this ?

    Greasing prop shaft u joints that have no zerks

    A shop here botched swapping the u joints out of my propeller shaft. Its a toyota prop shaft with a center bearing, with staked on joints. So the shop removed the stakes and replaced the u joints with zerk type. Unfortunately since this is a stake on type, the inner surface of the yokes are not...

    Toyota 85W-90 LSD oil in open diff

    This GL-5 oil is sold here and I like the viscosity spread, but I am concerned about using a LSD oil in an open diff. Is there any disadvantage using this in an open diff ?

    Noise on decel, some kind of rattle.

    The whole story is, my diff (RWD) had a mild clunk when shifting from N to D and from N to R, or P to R. It also had a whine when engine braking long downslopes. Since Mk3 Supra/Gen2 Soarers are notorious for crush sleeve issues after decades of use, I decide to rebuild the diff with a "pro". He...

    SVL by Dana. What does it all mean.

    Here is an excerpt from their website : English isn't my first language, but don't some of these terms seem contradictory or mutually exclusive ? What is your experience with SVL parts ? I am considering buying a Ring and Pinion set.

    I was wondering if given a same diff housing size , same ring and pinion size, lets say 8" Ring, 41 Tooth with a 9 tooth pinion, will there be any differences in the helical gear cut and angles? Is the gears for the car version quieter ? or are they all the same ?

    Going to wider rims on same tires- effect on sidewall

    Something I thought about, see illustration below. So the tires in question is 205/65 R15. The stock rims are 6jj. I was thinking of going to a BBS RS with 7jj, as it has bit of a lip so it pushes the edge out by nearly an inch. Also since its wider, the sidewall should bulge less like in...

    Anti Aircraft "wires"

    I remembered watching the pilot episode of Airwolf, the assistant said the "passive defence mechanism might force him out", then the pilot is shown exclaiming "wires" then he pulls airwolf up and over the canyons. Do militaries actually put up such wires in canyons to deter low level aircraft...
