My diff is leaking  

Noticed it on my grandparents bricked driveway, its not leaking much, very small drops. Although it looks bad from the photo underneath with the flash on! - I circled the bit which i suspect is leaking:




This is the leak, very small had to cirle it from the car being parked there for 2 days:



Over a period of time, if the car had been parked for several days the leak is pritty small.


What stuff can I get to clean the diff up, with my Grandfathers Pug 806, his mobile mechanic used some kind of spray underneath and it got rid off all the oil and crud. What can I use to clean it all up and idenify the leak better? - And should i be worried?  :-/

My diff is doing exactly the same and with the same amount of oil also

i think mine must be the front bearing seal that has gone/leaking, i wolud have thought the only cure would be to replace the seal but i would have thought that would big job involving undoing the main nut  posibly alltering the bearing preload which i suposed to very difficult to reset.

 if the leak is only minor like mine i would sugest just keep a eye on the oil level every now and again and top when nessarary,

as for cleaning try some GUNK engine degreaser and a stiff brush or even a soak with some penertrating fliud and a jet wash that should shift the oil.

cheers, i have only noticed it since my grandparents go their new drive!!

But the amounts are so small, think Jaime has some GUNK, someone reccommended WD40?

[TheBoy]

Yeah, try a bit of gunk on it to clean it up...

I have some here, you're welcome to borrow it...

Cheers mate, my grandparents are a little annoyed at the stain on there brand new driveway. Might get some GUNK myself to clean up the mess i made!

There is special stuff for lifting oil stains out of drives, though when oil soaks in it can be a problem...

My nice block paving driveway has about 6ft wide gearbox oil stain that is very soaked in, so far nothing has shifted that

Thats why Mark and I used clay pavers for our drives, oil cant soak in like it does on concrete.
Have you tried the oil patch cleaner that Wilco sell? scrub it in, leave for a bit then wash off. shifts most things but leaves a clean patch which shows up the rest of the drive.

have heard that "cat litter" is very good for oil stains

To clean the diff I would use Traffic Film Remover from MachineMart, use it in a garden sprayer then wash off with hose.

If it is the pinion seal I have written a guide for this but not posted it yet as needed some photos but could post a text version for you.

very true we use a industrial version at work for oil spills/leaking machines etc.

Thanks Pete, just Froogled it and come back with some good prices. Generally seams to be used for hi-pressure washers.

Do I need to dilute it before spraying it, if so what kind of mix to water? 50/50?

Cheers

I was going to suggest that......if its a new driveway....you will be able to without it noticing.

The blocks Tunnie, are only sitting on fine sand and are put in place with a wacker plate.
Get the block out, turn it over and , sprinkle some fine sand in the hole, put the block back in and tap it back down with a block of wood. Once level, sprinkle more fine sand around the outside edges and sweep away the excess.

Jobs a goodun  [smiley=thumbsup.gif]

To shift old oil etc just apply neat by brush or sprayer then leave to soak in for a while before washing off with garden hose.

Its worth putting down a plastic sheet etc to protect the drive while you do it.
