Factory Oil Light On, Epic Fail Options

[wickedcreationsi...]

Alright. I have a 94 St with a frankensteined 7a-fe/4a-fe motor in it. I say that because I took the good parts from a 7a and 4a to make one good motor. The motor that came out had over 200k on it, and these two both had around 80-90k. That all took place in about March-ish. The car has been running good since then, besides the occasional small issues. The other day when I was driving, the oil light started flickering on and off . I was just driving normally and not beating the hell out of it either. I pulled over and checked the oil level and it was good. I do have a small pan leak, but nothing too serious. But I do have to replace the valve seals and piston rings cus it huffs blue smoke. The light doesn't stay on tho. It just flickers. When you have the car on and are just idling, it is on longer before it flickers. But when you are driving it is on less and less.

Oil pump going bad?

Short in a wire somewhere?

Thanks in advance if you can help me out!!

you'll need to hook up a mechanical oil pressure gauge to see whats really going on, you could just have a bad oil pressure sender.

i do have an oil pressure guage, and occasionally my oil level light comes on, since i know i have oil pressure and plenty in the sump i figure its a sender issue, when the light stays on for a prolonged period of time and the light begins to annoy me ill change it. Let us know a rough price if you get one.

on a cold start my oil light will stay on for 3-4 seconds. its very agonizing for me worrying about my just rebuilt motor. i might have to invest in a oil pressure gauge.

ok. so its been a while since i posted anything on here. but i did figure out my problem. and totally kicked myself in the ass....

when i put the motor back together, i put my 7a head on a 4a block. it worked. but the oil pan on the 7a is a 2 piece, 4a only 1. so the 7a is bigger....... aannnnddd i used the 4a dipstick..... sooo yeah.

you see, what had haaappppened was...


just didn't have enough oil in it.....


its ok to laugh. i am lol. but thanks to all who replied.
