Oil dripping on ground under car when parked. Loss of oil when oil is checked. Smell of oil burning on engine.
i backed my car in drive way and the next morning i see oil leak in the front passenger side. i don't know much about cars so can anyone help me to know what i'm up against and what its going to cost me.
Oil leaking at oil filter mount.
Not fixed. I need advice.
Already had it up and could see where it was. But can't get to it. Next to exhaust.
while driving the oil light flickers on and off going down the road check oil level its fine but there is residual on the under carriage. very disappointed with gm right now. car is serviced regularly. was reading forums online and its not looking good
I found the oil to be leaking and burning on the exhaust. The oil is coming from several places: Front main seal , oil filter adapter, valve covers, and a couple of places at the intake manifold. The worst place is the front main seal. I am wondering if the PCV is working properly.. If I am getting high crankcase pressure this would be causing the oil to leak from any place it finds a way to relieve pressure.
oil leaking. have add a qt and half evey week
Small leak, no perceptible oil under the car, or out the exhaust. As noted, advised on routine oil change. A local Chevrolet dealer, (no Pontiac, right?)- relplaced the oil sensor-wasted $150 beans. My son has the same engine, and has lost a quart every 1m miles-47m now, and problem has existed since 30m, and multiple trips to the original dealer. I plan to take the info obtained from this site, (thx), and, finally, get this fixed-will advise results....
I was not even aware I had this issue, I brought my car in because the coolant reservoir tank was leaking and they told me I had an oil leak from the crankshaft seal. I had no indicator of this happening. The service warranty I purchased with my vehicle covered this repair in its entirety.
After spending $600 to fix oil pan/gasket leak, now advised crank shaft seal and timing cover leak. Shop wants another $700!
Diagnosed during a routine oil change at the dealership.
I have burned oil since 78k miles. But dealership advised It was not enough to be fixed under my warranty. Not today I noticed oil on my driveway. So I went to get an estimate and I need rear main seal set, crankshaft oil seal, timing cover gasket and oil filter adapter gasket so I am being told. This car is junk !
I have had the smell of burning oil coming from my car for about a year now. I have also noticed oil collecting on pavement where I park. Not fixed.
