Found an oil leak a couple of weeks ago when I looked under the bash guard, had it in the garage today and it's the crankshaft main oil seal on gearbox side. Only seems to be a slow leak.

Any rough ideas on cost to fix, garage said it's a gearbox off job (auto) and I want to get the ATF changed anyway, so do they have to drain the ATF to get the box off or does it come off as a sealed unit still?

Anything else worth doing if they're dropping the gear box off on a car with 96k on, does the PTU come off with the auto box so oil can be drained out easily?

Cheers

Cost me £600 (6hr book time plus around £15 or so for seal). Sorry can't answer your other questions.

That's an enforced dry January then 🤔 suppose it's cheaper than a new engine 🤣.

For a fiver, I’d be tempted to try a can of this first. Might soften the seal up enough to stop the leak or at least reduce it to a weep.

show me a Land Rover that does not leak oil

Cheers. Is the stop leak stuff safe, never had to try it before

^^^^ It could recondition the seal technically as that is what it's designed to do. Many high end synthetic oils also have additives that recondition seals as well as clean the engine. Since you already have a leak from the rear main seal, trying the additive can't hurt, just make sure to use the recommended amount and do not overfill the engine.

It's worth trying since it costs little compared to the 6 hours of mostly labour. If your leak is really bad, it probably won't stop it but it may turn it into a seep or do nothing at all.......you are basically buying time.

Thanks. I think it's only a slow leak, as there was oil on the bottom of the sump and gearbox but only a small patch on the under tray. I'm gonna check how much its using and see how bad it is.

Does anyone else find the dipstick hard to read as it seems to pick up oil off the side of the tube? Sometimes struggle to tell the level.

If you only noticed it when you removed the sump guard, I wouldn’t worry about it too much. When it starts leaving oil patches on your driveway though I’d be tempted to......park it in the street.  Past: FL2 TD4 HSE Auto

Read the dipstick after letting the vehicle sit overnight and before starting it the next day, you will get a good read. If you are not seeing consistent - or any at all - oil leaking on the driveway (ahhhhem, I mean street ), if the dipstick level is close to just below the full line I would check it again a a day or two later and if it does not change I don't think it's an engine oil leak. Best way to track down an oil leak is with a florescent die added to the oil.

You can wash the area you are seeing the oil off with soapy water and then check after driving it to see if it comes back.

I find washing being much easier and thorough with a brake cleaner spray.

I've got some silly strong tfr concentrate, that should get it clean. Supposed to mix 1:200, and if you mix 1:4 it dissolves tarmac 🤣

Just make sure it's safe on rubber or do your best to keep it off any rubber, seal and electrical!

AndyPP if you thought of "tfr concentrate" after my remark of brake cleaner, take into account the fact that the brake cleaner is alcohol based and therefore "rubber safe".
Like MotionInc said, if you use your concentrate, keep it well away from any rubber...

That's what the hooligans at the local CarWash use....no wonder the lawyer peels off the grill!
