oil leak

[C7JFM]

got a small leak on Vx 8 valve between the bellhousing and the 5speed box.It is gear oil leaking. Is it common? Is it easy to fix? will it foul the clutch in due course. any advice appreciated. sad.gif

Most likely cause is leakage from the sump to the bellhousing then out. Check the sump bolts first, and maybe replace the sump gasket. The 5 speed casing is pretty tough but cracks in it in cars with 200BHP+ engines are not uncommon. It tends to crack outside the bellhousing and leak directly out. Experienced mechanics can tell gear oil from engine oil and they may be able to help further.

I had a similar problem with transmission oil leakage from the gearbox joint directly above the gearbox mounting - mine started from nothing and within a month or so could rapidly drain all the oil from the gearbox. The only cure is gearbox out and strip to replace the gasket, or in my case, a good excuse to change the box for the SPC semi-helical jobby.

The front end of the layshaft is sealed in a rather primative fashion and tends to leak a little.

 

So long as it is not the input shaft seal which has failed your clutch should survive.
