Extremely low oil pressure
 

Sad day for the Z. I just measured my oil pressure and discovered it to be 50psi at cold start that drops down to 6psi at idle(180F) and 25psi at 2k rev. My engine doesn’t feel off and my oil level is good but I guess my oil gallery gaskets are done? My car only has 43k miles(2011 Nismo)

1)My questions is what aftermarket gasket should I go with, I know many vendors offer some like EPS tuning, Z1 and conceptz.

2)Should I replace anything else while the engine is being serviced(I’ve seen some talk about water pump but again my engine only has 42k miles).

3)Is there any good shops that do this repair and how much is a reasonable price to pay for this.

Thank you for reading.

I forgot to mention that I am in Phoenix Arizona. If anyone has any shop recommendations, please let me know.

Many vendors sell upgraded replacements starting from $30. It's up to you how much other work you want to do while you are in there. I did pretty much everything except the pumps, I have the same model/year just more miles and a bit of track time too. I used ConceptZ's kits many have also used Z1's kits.

I don’t really want to do much because my car only has 42k miles and I spent a lot during the holiday season. Is it okay if I just buy the oil gallery gaskets or do I need other things like the front timing chain tensioner and timing chain cover/o rings.

Just a crank seal. With the low miles you have I see no need in replacing any of the timing chain or tensioners.

If you do the gallery gaskets, you might as well replace the thermostat and water pump along with the various other o-rings and gaskets encountered in the labor process (found in the timing cover kit here). Tensioner is probably fine - I didn't bother at 100K miles since it seemed to be in good order.
