Description of problem (please be as in depth as possible):

I have a fairly hefty leak coming from somewhere on the engine. I don't have any blocks, but it seems to be eminating (or at least dripping) from near to the front passenger tyre, close to where the tyre rod reaches the subframe?

I have tried to take a picture of it, the area is highlighted in yellow, this was taken underneath the car with the said tyre in the foreground. The one thing I don't think it is is the gasket cover, as I recently fitted a new rocker gasket cover and didn't see any evidence of leakage. Any ideas? Thanks.

I would guess at crankshaft oil seal in the timing chain cover.

I would guess at crankshaft oil seal in the timing chain cover.

Seconded, its the only thing bar maybe the fuel pump that can let oil out on that side.

Well, maybe the oil filter / filter spin on bit, so check that first, but I doubt it.

Thanks for the feedback - looking at a few threads it doesn't seem an easy or quick thing to do :/

Hi,

It kinda looks like it could be the gearbox driveshaft oil seal as the subframe looks the wettest directly below the inner pot joint.
That said, as others have suggested timing chain crank oil seal.

Cheers,

Steve.

Its the same as mine. The oil comes out of the seal behind the pully and drips onto the subframe. then it just finds its way down to the lowest point before dripping. when you are replaceing the seal its best to fit the timing chain cover loosly at first and then fit the crankshaft damper pully before tightening up the timing cover. this will help to centralise the seal over the pully and stop future leaks.

Ah interesting - is it a difficult job to do?

If it is the crank pully seal, its not so much of a hard job to do, its just you've got to take a few bits off to get at it.

As above...Not difficult, but time consuming...Prob 4-5 hours work. Drain water, Rad, fan and altonator off, lock up engine (I use an old shell bearing in the flywheel) and undo the big pully bolt. Its a tight one. Drain oil, remove pully and then timing chain cover, replace seal and reverse of the above, Simples...But check that this is deffo where your leak is from first. Run your hand under the pully. If its wet with oil then thats your leak.
