my 1999 buick has developed an oil leak that i can not find, it is on the water pump side of the engine, the belts are not wet but below the power steering pump it is very saturated with oil, i am losing a quart of oil every 2 days, is possible that the timing chain has become so loose that it has worn a hole on the timing chain cover? and how long is the timing chain itself good for, i have 200,000 on the engine, it looks has though i might have to pull the engine just to find the leak.

Oil pressure sensor is known to leak.

Agree....that'* where I would be looking first.....comes right out of the harness.....

did not mean to confuse any one, I made a reply to mike about ICM, but I also made a new thread about oil consumption on the Chevy pick up trucks that I had a question about, it seems that from 2008 to 2014 GM had problems with truck engines burninig oil and fouling the plugs and was wondering if GM solved the problem?

thanks for helping me out with the oil pressure sending unit, replaced it and no more oil leak

you can delete the one about the oil leak, thanks again for everyones help, Kahplah' (that means success in klingon)

Qapla'!
