Would like to know what happen. What was the cause?

Elmo370z 07-01-2017 11:47 PM

is it a 09?

Opened the downpipes and dropped the pan.. not a single thing blocking the pickup tube and somehow the turbos still feel healthy with no resistance and no shaft play.

Any ideas why there was no oil pressure?

Oil galley gaskets are a common problem.

I dont know at what pressure the oil pressure switch closes. I will see if I can find it in the service manual. Perhaps you only had very low pressure rather than zero pressure. If the engine was only at idle and not being driven, it doesnt take much oil pressure to sustain. How much was the car driven or run with the light on? It sounds like it might be possible that you dodged a bullet. I have seen engines last for years of abuse after brief oil pressure mishaps.

I actually hooked up a mechanical guage (cheap tester) and it didn't move at all which is what worried me.

I doubt it's the gaskets since that's a pre 2012 problem i believe. I also find it weird that the oil filter gets filled as soon as i crank it but the pressure gauge never shows anything. It's almost like the oil never comes back from the filter.

Only thing left to try is to remove the sandwich plate and try it with just the filter attached to the engine. I just have to order the shorter oil filter stud.

Oh man... Hope you find the issue.

A stupid question - your oil pan spacer came with a matching oil pickup spacer/gaskets, yes?

I'm not sold it would be the OEM oil cooler sandwich... since it hasn't changed for this install... Also, I have taken mine off... it is a pretty simple device and seems difficult to clog.

Hope you get to the bottom of this soon, i've got my fingers crossed the motor is still healthy.

Good news! Finally found the problem. Somehow after removing the Mocal sandwich plate and getting the pre '12 stud, it works perfectly. Approx 100psi of oil pressure at idle.

The turbo return line was opened though haha so I have to clean up that mess tonight.

Did you have the thermostatic Mocal plate? If so, that thing is bad.

Yes that's the one I have. Unfortunately was with the car when I bought it.

And what are you basing that on?

It has a thermostat inside that opens up. Not sure why this happened. I would have to take it apart to see. I have one on my car and would like to know myself.

I think the way you worded it - it sounded like you were saying the Mocal plate is bad in general, not that this particular one is bad. =)

I think tons of people are running Mocal plates and are happy with them... unlike the Mishimoto trash.
