i guess i had an unlucky car, im sure boost and outings at the drag dont help either, im just thankful i caught the issue with my defi gauge because the OEM oil pressure light never came on. this ultimately saved my motor.

Again.To be clear the gaskets did not fail, they were completely intact. The fasteners backed out causing drops in oil pressure, why did they back out? i can only speculate.

Do you have aftermarket engine or trans mounts thus causing more NVH?

You do not need aftermarket parts for the screws to back out.

That's only good if you can raise the car that high. Even on jack stands. You have to go through the top.

It works ok stands also, I’ve been doing it this way for years.

Me too. Use to be a ASE Master Tech. I've done from the top, from the bottom, through the fender well, through the grill.

Just a question. And bye the way, I agree - great write up by jmroy6.

Having just seen this, is this an isolated or rare incident, or is this another potential chronic problem with the Z?

I did mine from the bottom with a chain wrench and breaker bar. That is what
I have always done with crank pulley bolts that you can not get an impact on.

I couldn't get high enough with my jackstands to go through the bottom. If i had a lift, no problem.

LOL, I did it. It was a pain in the butt but nothing out of the normal.

Anyone got any tips on getting the lower oil pan off? I got all the bolts off and I can’t seem to loosen the sealant.

Nice write up, only thing i would add having done this myself before this guide existed is that it’s better to use a large flathead screw driver on the oil galley fasteners as i tried using the exact size phillips that fit snug into the fasteners and because the metal was so soft it still started stripping away at the fastener when trying to turn it. Also, take care not to seal off the chambers on the front timing cover that provide a drain channel for the water pump. Some knucklehead had sealed off mine previously before i opened it up.....oh and oddly enough I didn’t have to use a gear puller on my crank pulley, most likely cause i had soaked the whole pulley in pb blaster overnight lol

Fuel pressure release

Thanks for the write up!

Wondering if it's necessary to release fuel pressure before taking everything apart - did you do the fuel pressure release procedure?
