Hr oil pump failure?

No great ideas, if you haven't already it might be a good idea to check the oil pressure with an external gauge. The sending units generally fail railed high or low but it could be good to check and easy but probably not the case. I am thinking you next steps might be to pull the oil pan and look at the pickup and make sure it isn't clogged, then look at the pump. This is all assuming you still don't have any external leaks.

This vacuum line was not hooked up correctly. Apparently the previous owner had capped off where it was supposed to run from the valve cover to the hose between intake pipes. It caused my oil pressure to be extremely low, so that problem is solved. As for how lean my car is running, I think it's because my new exhaust is a true duel and the sensor for the wideband is only reading 1 bank, have to figure something out there. It almost feels like the car is loading up under cruising conditions, once you start running it hard again it clears up and runs perfect. It even smells like its running rich. I'm going to see if i can get the issue tuned out in December. Until then i'm going to go through all my sensors and see if one if burnt out or not functioning properly.

just ran the codes again after i fixed my exhaust leak and i still have a misfire in cylinder 1 (p0301) and an advance timing code in bank 2 (p0021) any ideas?

well the breather for the valve cover was actually capped on mine rather than vented so from what I understand it was working against the oil pressure once the car got warm. It caused the gaskets inside the front timing cover to blow.

yeah, make's sense, it's wild such a small set of hoses can cause such big problems. I'm still getting a p0021 code so I think I'm going to change the camshaft position sensor for bank 2, see if that will solve it.

Is it common for the oil pump to fail in the hr's or has anyone else had theirs fail? That's my last step in trying to solve my oil starvation issues before I just cut my losses and get rid of my car. At this point I have; changed my oil pressure sensor (twice), moved to 5w40 oil and changed the two internal gaskets inside the front timing cover notorious for leaking oil pressure on the hr's. Now I have a dry lifter, I have not been operating the car with this oil starvation issue. Any suggestions would be great, the car hasn't even broken 60k miles. I have no upgrades beyond test pipes, exhaust and intake.

my oil pressure is high. in 6th gear at 2k r.p.m. im hitting 90 psi and 110-120 on start up alone. and idle at 30psi. so i might be kinda same boat. Ive changed the sensor and sending module along with the oil since ive seen the dealership use higher weight in the summer (dumb ****s) so im def subbing to this post.
