Hey
I've got a serious problem with my cars start up. The car will now on occasion on start up have a very loud knock that lasts anywhere from 30 sec to 5 min. Had gone away every time but am wondering whether it's fixable? The first time I checked it was low a quart of oil ( not the first time but had been running great the day before) so I filled it up and it seemed to help. Now the second time today when it happened you could actually smell oil burning. Noise went away and once it warmed up the car started back up fine. Could it be an oil sending unit or something with a cold start issue?
The car has 373,000 kms but I love the car and have done way to much to it to give up on it. Any help would be super appreciated.
