Need some assistance here, did an oil change today. I was VERY low on oil and happened to check my catch can and saw this coffee like sludge in it? Wtf is this?



Also, anyone know a part number or title for this crankshaft sensor plug in connector? It's part of the harness that connects with the oil sensor/sender plug in next to the oil filter. It's what plugs into the bigger female CKP sensor itself. Mine was frayed and was nearly ripping off so just yanked it haha. Wait.. uh oh.




By the way, has anyone installed an electric oil pressure gauge? Need to know what I need to get it done.
I don't know if you replace the oem sender plug with it or find another port for the aftermarket sender unit.

 

The chocolate milk is oil and water mixed, probably from condensation-but possibly from a blown head gasket or bad water pump.

For the connector, go to the wrecking yard and get one, probably from any Nissan of the era, and solder/shrink wrap it it on.

1/8 BSPT to 1/8 NPT adapter and T-fitting if you want your idiot light to still function.

Thank you for the quick reply. Just the answers I needed. Can't be a blown head gasket but could be the water pump.

 

Refresh, put some links in for yah

 

Even better. Doing a bit of research, I believe it may be condensation from the recent chilly weather. Do I need 3AN size SS braided hose?

 

Pick up a terminal release tool for peanuts at Radio Shack or off ebay/Amazon and reuse your harness plug. I'm sure the tool will come handy in the future too.

 

Its water from cold weather. My last three cars had the same thing in the intake.

 

I'm gonna have to clean this can a lot then, since it's getting colder.

Terminal release tool? Hm, I was thinking of reusing it but didn't know how to actually open the plug up to release the leftover wires inside it. I'll look into it.
