Engine Oil Leaking Problems of Chevrolet Suburban

Oil was changed at approx 72,000 miles. New filter and quaker state full synthetic 10w-30 oil. Current mileage as of oct. 11, 2015 is 78409 miles (15% oil life remaining). I have had to add 8 qts. Of oil so far. There are no visible leaks and exhaust does not smoke excessively. This is definitely not normal. Engine runs good otherwise. I am in the process of making an appointment with gm dealer for diagnosis.

My 1997 Chevrolet Suburban c-2500 is leaking oil from underneath the engine and making engine very "hot". This happens when I'm driving this vehicle. I touch the engine hood and feel that it's very, very hot. I just went home to prevent any fire or accident. My mechanic said it's not ordinary for this heavy duty truck to leak oil with only 77,000 miles. I need you to investigate my problem and contact gm. You can email me at villamej@rcn. Com for an updates regarding this problems. Looking forward to hear from you soon. Thanks.

This vehicle has always used an excessive amount of oil. Must add at least one quart between each 3500 mile oil changes. No leaks have been detected and nothing seems to make a difference.

The engine consumes approx 1 quart of oil every 1700 miles. There is no oil leaking under the vehicle.

Since 2008 our Suburban has required oil servicing on average every 2 months. We took it to many dealers and was told we needed to be able to track the consumption somehow. I stated, can't you check when the oil servicing light comes on and was told no. Don't know why it consumes so much oil and it's not leaking.

Vehicle has shut off several times while traveling at highway speed. After coasting to the shoulder and several attempts, the truck restarts. The truck also sputters during acceleration. The dealer has replaced the crankshaft sensor several times and has replaced four warped rotors that caused the brakes to be spongy. Two of the power window motors have been replaced due to inoperative windows. The oil level in the truck drops between (frequent) visits to the dealership. The low oil indicator light first illuminated when the truck had only been driven 3900 miles. The dealership can't find a leak.

# 1. The day after I first puchased and picked up my vehicle it smoke us out of the parking garage on our vacation in oceanside, CA. #2 the brakes were very spongy and not anything like the one I demoed when I found this vehicle. I almost had an accident on route to oceanside. The last two trips in this has not been fixed and I had to rent a car again. # 3 about the 3 rd. Day into our new vehicle I noticed the parking brake wouldn,t always hold the vehicle, even after putting it in gear, with the brake fully applied it would fail but not all the time. # 4 after reporting the smoking problem, (still on-going) I had a no oil pressure warning and notice the gage didn't respond for about 10 seconds after starting the engine, then I had pressure but a constant low oil warning kept appearing on the message center. This is when it only had 1400 miles on it. I noticed some oil spots forming where I parked, I crawled under near the right rear side of the motor to find oil dripping from the engine and off the suspension near the engine. Its now been in 3 times for smoking, leaks and various other engine noises (lifters, right bank). # 5 the vehicle has pulled to the right since new. I called them, they said wait till you get a few miles on it so everything breaks in. Wrong answer. I checked the tire pressure. It was uneven on all tires, mind you they were supposed to check this before I purchased the vehicle. Average psi 30, should be 40-44psi cold. It helped but still pulled to the right. At 5000 miles I personally rotated the tires, this still didn't fix it. Upon bringing it in for all the formentioned and last problem which by the way required renting a car twice they finally took a look at it and know it pulls to the left and the steering wheel is no longer level. # 6 the right bucket seat won't lock in at the hinge point properly. They said there was a fix coming for the engine and the seat from the factory but as of yet nothing from chevy or the dealership.

Oil plug failed causing oil to leak.
