Car Forum / MINI / July 2003Terminal Oil Leak???
Ok folks I've just tried to carry out a full service on my sister's/nephew's 1992 Mini British Open Classic LE and whilst attempting to put in fresh oil (Castrol GTX like it matters anyway), I heard a strange glugging noise and found my garage floor becoming awash with oil. Ok we've been aware there was an oil leak, well oil has been spraying itself around the engine bay since the car was bought in December 2001 and a garage reckoned it was due to a worn drive-shaft seal. But after sticking my head underneath and looking up the engine whilst my wife poured a little more oil in, it's clear the leak/torrent is coming from above the drive-shafts and in the vicinity of the oil pump. So is it an engine out job as the Haynes manual claims and why should the seal or oil pump fail? Any help appreciated, but it looks like my sister's in for a big garage bill I expect? I'm now getting paranoid and wonder if I fitted the rocker cover gasket correctly after adjusting the tappets. Well I did use some instant gasket to help hold the bloody thing in place whilst I lowered it, so I can't imagine that would be the cause?

Well, I don't know... there's always something to be said for being "complete" at anything. ;-) Here I was thinking perhaps you had taken offence at a simple handling error at your news server but in fact you're just going around being a cock to everyone. I like to think this news group is a great place to get help and offer advice and the people here are genuinely helpful. If you want to start sh.t go to another news group. > > Ok folks I've just tried to carry out a full service on my > sister's/nephew's [quoted text clipped - 32 lines] > > What a complete moron. > > Ok folks I've just tried to carry out a full service on my > sister's/nephew's [quoted text clipped - 32 lines] > > What a complete moron. I have read 2 of your messages (top posting!) and there seems to be only 1 moron arround here.... get your head out of your back passage > leak/torrent is coming from above the drive-shafts and in the > vicinity of the oil pump. If the leak is that major you are bound to have noticed it before. > I'm now getting paranoid and wonder if I fitted the rocker cover > gasket correctly Take the air filter housing off (assuming the standard one) so you can see the back of the rocker cover, my money is that the rocker cover gasket moved slightly, doesn't seal and you are pouring fresh oil straight down the back off the engine - done that myself once! Make sure you wash the oil from the exhaust manifold as best you can before starting, and when you do start make sure it's outside coz it's gonna smoke from the engine for a while until it's burnt the remnants off.

Cheers Shaun, turned out the rocker cover gasket wasn't sealing properly after all. Well I bought a new thicker one and that went on a treat. Funny how these things happen when you consider I've done the same job hundreds of times, oh well at least it was a cheap fix.

The oil pump is deep inside the motor! Anyway, you've got a major leak which dumps oil straight out on the floor when you pour it into the rocker cover, but only a minor to moderate oil leak when the motor runs.... Where is there oil when you're filling it, but not when it's running? Rocker cover gasket is one strong candidate - if the back edge comes adrift, und normal running you'll get a bit of leaking there, but when you fill the motor via the rocker cover, it will overflow out the leak. Another possibility is the tappet cover gaskets. > So is it an engine out job as the Haynes manual claims Don't pull the engine out until you've determined where the leak is. Diagnosis without dismantling is much easier than unnecessary dismantling and reassembly! > and why should the seal or oil pump fail? It really sounds like you haven't got the diagnosis bit worked out yet. > Any help appreciated, but it looks like my sister's in for a big > garage bill > I expect? No way to tell until you determine where the oil is getting out. > I'm now getting paranoid and wonder if I fitted the rocker cover > gasket correctly after adjusting the tappets. Ah hah! > Well I did use some instant gasket to help hold the bloody thing in > place whilst I lowered it, so I can't imagine that would be the > cause? If the long straight section of the gasket above the manifolds falls inward and doesn't seal right, what symptoms do you think you would get? 8-) Stop panicking and go and have a good look at it. |
