So, I discovered a leak!
I noticed that a small amount of oil was leaking from the turbo oil drain, where I had put the adaptor in. After trying to seal this twice over the last two weeks, I decided I would have to use an alternative method to sort this once and for all!
Here's the offending item:
I had to separate the steel sump pan from this aluminium windage tray because the oil pick up has to be removed.
Removed the threaded adaptor, cleaned out the threads with the tap I'd used previously and polished the top face clean.
I also drilled out the small bolt thread and through into the tray. I wanted to weld it up and i didn't want to trap a pocket of air in there.
And welded:
This was hard to get the TIG torch into!!
And cleaned up..
Unfortunately, one slight slip of the wire wheel in the air die grinder, resulted in some fine scratches on the adaptor :-( I did lightly sand these off smooth. At this point, I didn't think it was worth cutting off to start again, as the black anodise had turned brown with the heat from welding (which I quite like actually). See what you think anyhow:
I then set about cleaning the face which the steel pan mates against:
Before I put it back on, I spent a couple of minutes looking around underneath, quite pleased with how clean it is:
And found this stamp (I knew they were, but it's nice to find a stamp!)
And all back on, ready for the steel pan..
Much better I think
And that was all of Sunday's efforts and took about 7 hours!
More to come, as I decided to give the steel sump pan some TLC while it was off.
