Re: Oil pressure low, oil light comes on and off......
 

is there a chance the wiring is loose. i'd assume because it's a single wire hookup that it just connects ground when pressure drops.

in that case check the wiring for breaks, if it shorts to the body or block the light may come on.

Well I feel stupid, people change your oil filters when you get a swap in. I thought, wll this guy was driving the car so the filter should be ok...nah wrong!!! The filter was full of ----, literally, weighted like 5 pounds and that was empty, no oil in it, just random garbage. New filter in, drove it out....Perfect so far.....

So I guess sometimes it's the simplest thing, when you are ready to bust out the tools and change the oil pump, check your filter and pressure sensor before anything else.

I'm glad I got this figured out, now I can spend my money on internals for this thing. :8 :y

better hope the bearings/cams/etc are alright if it actually was running on low pressure

Re: Oil pressure low, oil light comes on and off......
 

i'm having a similar problem...faint oil light going on only when i go into neutral. as far as i know there should be plenty of oil but it will go on for a few seconds and flicker out.

Re: Oil pressure low, oil light comes on and off......
 

having plenty of oil and having plenty of oil pressure are two different things

Re: Oil pressure low, oil light comes on and off......
 

I'm hoping there was no damage, I drove the car maybe 3 miles so far after the swap. If there was any damage it came from the previous owner. I'm planning a quick rebuild, so I'll be checking some things as I go. We will see soon.

when mine done this, it turnedout to be the main bearings were bad.
