Remote Oil Temp Sender Cover Plate, gasket?? Options

OK, so while I'm waiting on the final verdict on my fuel injector cleaning project, I thought I'd chase down an oil leak.

What I found was that oil was seeping out of the cover plate for the remote oil temp sender. I removed the cover plate that is held on by two 10mm bolts. With the cover removed, oil really seeped out of the bolt holes.

I assume and hope that's OK?

Question is, if they leak that bad, shouldn't there be a gasket for that cover?

The cover and the plate that the sender mounts to were very nicely cleaned and powder coated, but no gasket.

I see a gasket in the PET, but not sure if it is for the cover plate or the inside plate that the temp sender screws into?

Thanks,

Len

Yea, because those 2 bolts are the only thing that holds the cover plate, and base, on the case. If you had wiggled the base a little more, the base may have dropped out and you'd have gotten the whole oil sump dumped on the floor. I don't see how the gasket between the cover and the base does much. The red o ring and the sealing copper washers on the bolts do more...

I see the assembly as:
case
red o ring (PET 111-05 #50 021.101.269 A)
base with sender
gasket (039.101.287 not shown in PET)
cover held on by sealing copper washers (PET 111-05 #51 N013.803.2) and bolts, 6mm.

Wow - thanks. For once luck was on my side. Good to know. I pulled that cover off because I saw it was the source of my leak... once off, I left it off for a bit, but lucky for me, I put the bolts back in to stop the oil from dripping.

For now, I made a paper gasket and slapped the cover back on.

So when I go to do it right, how much oil can I expect to come out of there when I pull the whole thing out?
