Leak Sealers that actually seal leaks. Do they exist???

[GarrettMacD]

I have a seal between the engine and gearbox that's gone.

For me, it's not a problem. I just put in about 500ml of oil every thousand miles or so, and all is fine.

But the stains on the block paving are a PITA.

Can anyone recommend one of those can of super-sealer-in-a-can-that-also-magically-increases-horsepower-and-reduces-emmissions???

Or just a plain old leak sealer that I can pour into the oil.

frosts do a stick thing which might work

I assume the original question is about a leaking crank oil seal rather than a leaky joint?

Er, I think so...

When I got it MOT'd the mechanic said that a seal had gone between the engine and the gearbox. So replace the seal it was either an engine out or gearbox out job. The seal itself is a couple of quid, the labour was £140 with the gearbox out, and £180 with the engine out.

That's about the full extent of my knowledge. I would quite happily drive around in blissful ignorance if it wasn't for the stains on the driveway...

Depends on the question.

Leak Sealers that actually seal leaks in the short term while replacing the failed oil seal can be arranged - yes, most of them in fact.

Leak Sealers that actually seal leaks and are lumps of plastic/rubber that you have to part-strip the engine to replace the failed equivalent - yes, most of them (though some real crap floating around the classic car market these days).

Leak Sealers that actually seal leaks, only cost £1 and can magically do the job of an oil seal the manufacturer spent time and money developing for another 100,000 miles - no.

If oil (engine or gearbox) is dripping out the engine/gearbox join the longer you drive it the more chance you'll have to replace the clutch too when you finally replace the seal, as it will be saturated.

This could turn into another Snake Oil thread.........

bite the bullet and get the job done, new clutch whilst your at it as there is a high chance there is oil on there allready.

as for stop leaks etc its all bell cheese

There is an advert at the bottom of this thread.
http://www.repairproducts.co.uk/page57.htm

It talks of something I have heard of before where the product replaces the plasticisers that are added to seal materials to give them flexibility. These leach out over time leaving the seal hard and brittle.

Against the cost of engine or 'box removal it has got to be worth a try.

Wiping the vinyl envelope of my waterbed with such a product is a recommended maintenance routine.
