W58 leaking from rear main seal even after replacing

[Cuzzo]

My seal leaks too in the w55 i got.

I have tried 3 new seals.

Two different tailshaft yoke.

I raged alot and still havent fixed the problem. I have no idea what it is. Maybe the tailshaft is on too much of an angle or that the gearbox is worn around the outside of the seal. I tried using no gasket goo and one with gasket goo. no difference.

Secondly make sure its not actually leaking from the shifter housings and dripping down.

Good luck!

If the seal's the right size, installed straight and the surface it runs on isn't bad, then how about too much bearing play.

[SupraM8]

it could be the bush in the extension housing has to much play or you need a speedy sleeve on the yoke

[cambelt]

Most of the older boxes are getting tired and will need the bush in the extension housing replaced as when worn it allows the yoke to move out of the seals sealing range . Toyota seals always work better than an non gen peice of crap.

Is Full pull down of the box needed to replace that bush or just the extension housing?

The new seal i obtained is the right one, problem solved. thanks everyone for the tips.

So for all your guys with w58's in soarers make sure you get 90311 38032


Another thing is it normal too sit on 100kmh and the engine sitting at 3500rpm? i realise this was an auto car to begin with so im assuming the diff ratio's are different to original manual soarers? or is it just because i have a lightened flywheel?

Suspect you have a diff ratio like 4.3, that will do this.

or is it just because i have a lightened flywheel?

Do you under stand how cars work?

You can have THE lightest flywheel in the world, and your engine will still have to do whatever RPM is dictated by the gearbox ratio, diff ratio and tyre circumference!

The weight of the flywheel doesn't come into it! At all. Full stop.

Oh it can. Fidanza lightened flywheel used to slip due to the steel pressure plate being warped. Fixed now, but Lightened Flywheel == Higher RPM at cruise...

Although given this isnt a normal situation. But im getting narky at people who are insisting absolutes atm. "Shouldnt have any effect..." fine, "Cannot have any effect..." BS.

My apologies,

I should have added the disclaimer that "A correctly functioning clutch with a light flywheel won't effect engine RPM"

Also I wouldn't say the slipping you described (Fidanza) was due to the flywheel being 'light'... it was due to the clutch system not being up to scratch

But I'll watch my non-disclaimed absolutes for you in the future

On the same token of absolutes, as an example if I told you an M6x1 (10mm long, within ISO standards) bolt will absolutely be able to have an M6x1 nut (less than 10mm long, within ISO standards) screwed onto it, you would be upset?

Also my memory indicates that I thought he had an OS giken twinplate from memory...

Edit:

Disclaimer: 'Correctly functioning clutch' in the above context is intended to identify and describe a clutch system that is not slipping unintentionally in the course of fulfilling its function. (Trying to clear up the absolute of 'correctly functioning clutch' )

Im not sure but i was reading something about lightened flywheels may affect it a little due to less inertia than a heavier one. but im no expert

[CrUZida]

Suspect you have a diff ratio like 4.3, that will do this.

Even a 4.3 wouldn't do this.

I'd guess a 4.56 with a W57

In my experience, usually NOK.

You are correct
