Hello

 

I'm removing the flywheel cover (Wok) to get the flywheel and clutch out

 

To then get the clutch housing off

 

To replace clutch housing oil seal and the gasket between the clutch housing and the engine / gearbox

 

It's leaking oil

 

Getting to the point....

 

Of the 8 (I think) bolts that hold the Wok to the clutch housing, I've removed 6

 

There are still 2 that I'm struggling with

The 2 at the bottom

 

I've tried from above and from under the car

From under the car, the front subframe is in the way

From the top, the wok itself gets in the way

 

Any tips, suggestions, special tools?

 

My swear jar is full

I'm starting a swear barrel

 

Thanks all

Im sure you modify a spanner to reach but give it a minute and one of the knowledgable people will be along.

As above - you may need to bend a ring spanner and then get them from below.  How high you do/don't have the engine jacked up at that end will help.

 

Is the flywheel housing casing gasket leaking ( that's quite an unusual on to leak)?  Getting that housing off in situ can be a bigger test than what you're experiencing now - to the point it is often quicker and easier to pull the engine to do it.

However, the rear main seal can be done in situ without removing that housing.

Those lower wok bolts are a challenge but do able,,, I take the Rad out, if its a side Rad.... undo all the stabiliser bars and losen the Rad side engine mount but do not remove the nut and bolts, just undo them as far as you can without the nuts falling off... then jack up the flywheel end of the engine as high as you can go (having fully undone that engine mount) but watch the exhaust and rod change so it just touches the underside of the car... this is as high as you can jack the engine in this situation.... then you should be able to get to the wok bolts as explained above.

 

The actual housing the wok bolts to is virtually impossoble to remove with the engine in situ, and bear in mind if you do remove it and replace the gasket (as you will need to if you remove it) you really should re shim the idler gear... a mission in itself ... so make sure the gasket really is leaking before you decide to renew it..

I normally undo them before lifting up engine,
And have a modded spanner bent into an S shape

Thanks all

Jacking and a bent spanner it is

Yes, it's leaking oil between the clutch housing and the engine / gearbox

Not between the flywheel wok and the clutch housing

I assume it's the clutch housing oil seal that's the problem, so I plan to replace it and the gasket between the clutch housing and the engine / gearbox

As above, IF I can get that far with the engine in situ

The exhaust, manifold, throttle body, air filter etc etc has already been removed

I possibly also need to remove the radiator as above too

Sounds like fun

Thanks again

Might be a silly question but if oil is dripping out of the hole in the clutch housing, the one that should have a split pin "dangling" in/from it. that usually indicates a primary gear oil seal failure. If you do have to remove the clutch housing, might be worth renewing the bearings in the housing too whilst its all apart, and be ready to measure primary gear thrust / end float, and idler gear end float

Sorry, I don't know where that split pin dangly hole is

The oil appears to be forming along the bottom edge of the gasket between the clutch housing and the gearbox

I think at this stage I'd take the engine out .. not much more to undo!

If its from the bottom edge then it does indeed sound like the gasket...

Oil always seems to be leaking from the lowest parts of the engine. It rarely is. It just collects there after having leaked from further up.

 

in this case I would be getting some UV leak trace additive and work out where it is coming from. As it might just be a incorrectly positioned rocker cover gasket.

[nicklouse]

If you do decide to split the transfer case off don’t forget to check the idler gear clearances as it is unlikely that the new gasket will be the same specs as the original.

Thanks. A useful link. I'll look for the hole. I've removed the starter. It's dry in there. Rocker cover gasket also seems dry and not leaking down from there. Should that mysterious hole have a dangly pin in it as the earlier post or should it just be a hole? Is it intended to act as an overflow pipe to warn of oily issues unseen within?
