Oil pressure dropping when hot would indicate something expanding and allowing clearances to increase, thereby letting too much oil through.

There isn't anything attached to the camshaft (other than the cam sprocket). Lifters could cause low oil pressure (and would tick).

The only reason im not sure its the lifter, is because he said it seemed to work fine in a cold start. No noise, leaks, or bad oil pressure. Only when its warm does this happen. Wouldnt a bad lifter cause be constant wether cold or warm?


Hes gonna check into it again and hopefully we get some good news this weekend.

Lifters in these engines are known for getting noisy after warming up. Everything gets hot, grows, clearances increase, and things start to slap around and rattle.

Thanks for your input, hopefully its not any internal stuff though. Im gonna talk to him again tomorrow, ill ask him to check it with a mechanical gauge. Ive heard some oil pressure sensors go bad after getting old.
Im still hoping its something small.

Sorry I couldn't update this any sooner. I just went to the mechanic and he told me the car was working fine now. He had replaced the oil pump again since apparently the first one he bought was defective. I have no idea how he decided the pump was defective but imma test drive the car tomorrow and keep a close Eye on the oil pressure and check for leaks and any valvetrain noises.

Thanks for the help
