Oil leak found.

[Mad4slalom]

Hi again, well the oil leak that I was thinking was possibly s rear main seal showed itself today . It is the oil pressure gauge line where the thin copper pipe enters the gland nut on the block, it is pushing out there and running down the back of the block and over the outside of the bellhousing. I have not yet tried to see if the nut will tighten up a bit. Any ideas how to reach this? I was wondering if a crows foot wrench might get in there. The kits are now supplied with a plastic line I think, anyone tackled this job ? Looks a bit of a pain, is it hard to get the oil pressure gauge out and re fitted. Any tips or suggestions welcome, TiA

There is a fitting that goes over the end of the copper tube
When nut is tightened, causes fitting to compress and prevent tube to pulling backwards and prevent leaking

One of the the very early 'issues' I had with my Vette some 20+ years ago was a severed copper oil gauge capillery line. What a mess that created. I simply bought a new replacement 'kit' with varying 'ends' to suit a multitude of vehicles - and yes it was nylon . Can't remember having major issues accessing the engine end of the line - I remember the under-dash part was the usual challenge of lying on your back and trying not to disturb any wires leading dashboard lighting etc......can't recall if I removed the drivers seat.

Have ordered s new line kit but is plastic not copper. I am wondering if I can shorten the copper line and re use the fitting for now or even plug the exit from the block so I can use it with no gauge until It arrives.

You could trim the tube if there is some slack, as long as it fully inserts into the tube connector
Assure if using a tube cutter that you ream the inside of that end to allow full flow
Check to make sure that crimp fitting did properly seat to the tube

Doubt the tube is the problem but the tube connector fittings or just not torqued down the top fitting
