The gearbox on my 97 1.6 escort is leaking into the bell hosing. I seem to remember there has been a small patch of oil under the bell housing for about the last 2 years. Anyway, when my mechanic changed the clutch (there wasn't contamination on the plates BTW), he pointed out the oil in the bell housing & said the gearbox (manual) was low on oil so he topped it up. Since this the leak seems worse, leaving oil about the size of a 10p on the drive overnight. My mechanic reckons it's an oil seal, requiring a complete strip down, costing around £250. On getting other opinions I have been told that this is rare & it's more likely to be something else like a cracked casting, & I'd be looking at about £450 for a recon gearbox fitted. My questions are,
Anyone seen this problem before & what's the likely problem, are the above suggestions likely to be correct? Are the above quoted prices OK? Is there any additive I can use to help slow the leak? I only want to keep the car for 6-12 months, is it likely to last if I keep topping up the oil? Could it be that the oil is leaking from somewhere towards the top of the box, so once the oil is low it'll stop leaking & I can take my chance with low oil, just risking having to have a recon one which is one of the above options anyway.
Sorry for so many questions, but as I'm not planning on keeping the car long I'm not happy about spending too much on it.
Thanks
Dave
