Low oil pressure!

jmroy6 · 01-31-2018, 12:08 PM

i will definitely change out the old guides/tensioners since everything will be apart anyway. I guess it would be a good idea to do an in depth DIY too.

Quick update:

Finally ripped the car apart today, oil galley gaskets were all intact, looks like this motor got the updated versions because they were some composite metal material instead of the old paper style. Anyway i didn't take it apart for no reason even though the gaskets didnt fail, the shitty fasteners did. On the upper galley two fastener were less than hand tight. So this is why i was getting low oil pressure drops, but no ecm codes (p0011,p0021)

Very lucky that they didn't back all the way out and land in the timing chain.

Due to this reason right here I am going to have mine done when I get my TT install done. Might as well do exhaust cams and an oil pump upgrade too. The motor will be out, why not.

This is on my to do list.

Looks like it was replaced and the mechanic didn't torque them down correctly?

Noop, common issue.

jmroy6 · 03-03-2018, 10:23 PM

Nope, this was the first time the motor has been apart since i bought it. the two of the fasteners circled in red backed out on upper galley.

Thanks for the DIY, I am glad you got it resolved. Based on the profile, I am assuming you are SC?
I am looking into a Z, and previously had a BRZ but the oil pressure light/ oil level never came on then boom the motor spun a bearing. When the motor was removed to assess the damage, there was no oil in the oil pan...
I wonder if any of these manufacture sensors are truly functional...

There is no gauge or light that will replace checking your oil. Once the light comes on or the oil pressure drops, it is too late. The damage is done.

Normal idle oil pressure is about 35 lbs. I have the warning light on my gauge set at 30 lbs. Hopefully if anything happens. I will be able to shut it down before damage. The factory warning light pops on at about 5 lbs.

Since the OEM sensor is just a switch... I wonder if maybe we can replace it with one that has a more meaningful threshold (like the 30# you have your warning set to).

Yes you can - as long as it's a mechanical switch and compatible with engine oil. Might have to use an adapter to match pipe threads. If you can figure out which sending unit has the setting you want, it should be an easy job. You may be able to order what you need from McMaster-Carr, et al.

Edit: And the switch action (NO or NC) needs to match.
