Ongoing Oil Leak


510_dreamin

Recommended Posts

I have a persistent leak in my L20b powered 510 that I cannot seem to identify. I have a small leak behind the rear passenger side of the oil pan, where towards near the bull housing bolts are. I have had the valve cover gasket, oil pan gasket, and front gasket replaced so far, and it has definitely slowed the leak down but not stopped it. Also, it seems to get slightly worse when I topped off the oil for some reason. The oil pan gasket is dry all the way around so it doesn't seem to be from there

 

Any ideas where the leak may be coming from?

ck the oil sender also if leaky. It may run down the side and run along the oil pan then drop down.

 

I had a bad one thinking it was a oil pan gasket. it was the sender diaphram

 

If the oil sender has been replaced this may be a case of SAE replacement threaded unit in the NISSAN block British Trade Standard engine block hole.  Adapters are readily available.
