My 2000 GS-R was in the shop about a few weeks ago. My cousin who owns the shop rebuilt the head ( OEM specs ) because my car was making some noise and it ran like it was on 1 cylinder. I got my car back 2 weeks ago and it was running smooth. I commute about 70 miles a day so the car itself has about 220k miles. Before the rebuilt , I had him replace the timing belt , water pump , oil pump ,and full tune up with all Acura OEM parts. Ever since he replaced the oil pump , the engine would eat up 4 quarts every 400-500 miles so I would fill it every 2 weeks or so. I've tried numerous weights of oil and brands and still receive the same results. I think that caused my engine to crap out. Now that the head was rebuilt and fresh oil , spark plugs , etc , I was hoping the problem would go away...Until today I was driving home from work and came to a stop sign my low oil lamp came on for a second... I was thinking oh no not again. I checked the dipstick about 2 hours later , it had no oil. I rarely go pass 5k rpm as this is my only car and also my commuter. Also there are no leaks. I put a large piece of cardboard under the car and did not see any drips of oil.

Do you guys think I have a faulty oil pump? I passed smog a few days ago if not matters. Thanks.

 

i recommend pulling the spark plugs to see if your burning oil, that would be the first thing to do. if you are burning oil i would then check the valve guides see if it has any free play or maybe it could be your headgasket if so check to see if you have oil in your coolant or coolant in your oil.

 

4 quarts of oil is a hell of a lot for it to be the valve seals or even the piston rings. There has to be some kind of leak somewhere. How does the car drive? Any smoke?

 

It drives perfectly fine... No smoke at all. There are no oil in the coolant.

 

start there.....

 

4 quarts of oil in 500 miles with no smoke or leaks, while not being run hard? That is virtually impossible. It has to be rings, valveseals, and every other seal leaking.

 

4qrts in 400-500 automatically means the RINGS are shot like no other and or he got massive cylinder wall scarring. This would put on a smoke show anywhere he goes.

also as of last year, in ca if your car smoked, it would automatically fail smog. I think we can rule out rings/scarring.

check between the bottom of the engine and tranny, if your rear main seal is bad, youll be leaking pretty bad.

 

my mate just had the same problem he's the process of changing

 

Yeah... My car passed smog. I'll have my cousin check it out when he has time. But honestly , I do not see any leaks. The car drives great and all...just the never-ending evaporating oil is giving me a headache. Thanks for the inputs guys.
