I have an 87 mazda rx7 gxl that is leaking around the pressure sending unit. I replace the unit and also did an oil change but it seems to be leaking from the same area. Does anyone have an idea from where else it could be leaking?

you check the hose that is attached to the engine from the cooler?
The copper crush washer that seals the hose to the engine can let oil leak out.
Check that out.It is in that area.

have you checked the most common place?
The oil pedestal where the filter mounts?
There are 2 o rings in there that often are hard from age and heat and don't seal anymore.

I may have this leak as well. Are there part numbers for those 2 o rings and where can I get the copper ring replacements?

Also, it looks like a have a leak around where the trans meets the engine. I pray it's not a rear main, but if it is how are is it to change on these cars? On my 240 it was fairly easy, but I already had the engine out.
