Intermittent oil light comes on at stop... replaced oil pump, oil pressure sensor, went to 10w 30 oil velocity....still comes on, usually after engine is warmed up, never on cold engine... oil level is good...
any suggestions?
Anyone ever have this issue with a corrective action that worked?
also went to a aftermarket cat and I keep getting a engine code for aftermarket cat. Is there a way to program a aftermarket cat to the car so the check engine light stops coming on?

 

Did compression test and cylinder 1 = 143.4. 2= 140.2.
3= 159.5. 4 = 132.8.
so all good but ...it's is low but within tolerance.
On oil pressure test....started at 40 psi and after 5 minutes dropped to 20 psi then 15 psi..... Minimum as far as specs is 20 psi....
I already replaced the oil pump, twice due to oil light coming on...so...what's causing this drop in oil pressure? I need some feedback...please?

 

it sounds like worn rod or crankshaft bearings. that would give you low oil pressure.

 

Thanks

 

Well. I ran a oil line from my Turbo to the bottom of a "T" and took my oil pressure sensor and screwed it in the top and ran a oil line off the side of the "T" to where the oil sensor went and I haven't had a oil light come on at idle anymore. My catch can even catches oil now whereas before it didn't. Great fix to the member who helped me resolve this oil light at idle issue¡!!
