MG Midget and Sprite Technical - Oil leak NMC
|I have a very minor external seepage of oil from a joint in the gearbox of my Elan+2, not enough to worry me but is just annoying finding the occasional few drops of oil on the garage floor.|
I noticed that "Frost" sell a product called "Oyltite" that they say can stop such a minor, non-pressurised, leak. Anyone have experience of this stuff?
|The ‘Oyltite Stick’. Yes, I’ve seen them used before - usually without much success. But then that was usually trying to hold back 1000’s of pounds of Avtur from a leaky old aircraft wing!|
It looks and works a bit like a big wax crayon, you just wipe off as much of whatever is leaking and then rub the stick over the crack to work the stuff in. I can’t see it working on hot oil but then I suppose it must be designed to cope with all sorts of things.
The usual oil leak from an elan is the top plate bolts come loose as the gasket gets older--The oil then runs along and shows as a leak either between the bellhousing and box or between the box and extension housing-or both---If you get a little shortish 7/16" spanner you can get your hand up the side and tweek the bolts up--not too tight though/ they're only little----it's a whole lot easier if you can get on a hoist somewhere and reach up in there
|Thanks for the replies guys.
John, no pressure at the leak so might be possible. Strangely enough I spend Saturdays working on an old aircraft wing - a Fairey Gannet.
William, the leak is at the joint between the gearbox and the rear extension piece, I had to remove and weld up a cracked exhaust pipe support bracket which is attached via two of the studs connecting these parts and since that work there has been a slight weep at the casing joint.
Is not worth worrying about just annoying and certainly not worth the effort of pulling the engine and gearbox.
It might be weeping along the threads of the two bolts you pulled out to remove the bracket and need the bolts pulling out and their threads sealing up, I'm pretty sure some of the extension housing bolt holes go right through to the inside
|Cheers Willy, hadn't thought of that, I'll have a closer look at those, but not for a wee while, it's about 3 degrees C in the garage at the moment.|
