I noticed spots in my driveway. I looked under the car with the engine running and I see a steady stream of fluid. I wipe with a paper towel and it appears to be oil. I also can smell a strong odor from the car when driving it. I had a shop just look at it and he said it was going to be a very costly repair. I am trying to decide if it is worth the money or trade it off.

I noticed an oil leak and did some digging. First leak was the oil filter housing gasket. It was a cheap part and relatively easy repair. The part is about $25.00. Tools for repair ratchet with 1/2" socket standard and deep socket, oil pan, paper towels, kitty litter. First detach negative battery terminal, because you have to disconnect the power from the oil filter housing. 1. Remove oil filter, let drain then plug filter housing with paper towel to stop leak. 2. There are four bolts which need removed. 3 for the filter and one for a plate covering the filter. 3. remove the two easiest bolts to access, then remove the bolt holding the plate. 4. remove the final bolt highest up, a bit tricky to get to, I used a deep socket. Use your hand to hold the housing in place so it doesn't fall on your face and remove the last bolt. 5. Remove old gasket. 6. Tricky but you have to line up new gasket and insert highest bolt all at same time. Also make sure you insert the long bolt next otherwise it won't fit. After that it is pretty simple. The bolts are 14 lb torque so don't crank them down, just snug is fine. Finally, attach the oil filter and clean up,

Oil pan gasket is a pain 7 hour job or more for amateurs, best to get done at shop about $600 bucks, have to lift engine and all sorts of nasty things. Good luck.

Since graduating college in 1980, I bought three cars:

A. 1982 Prelude that I kept for 12 years and 200,000 miles.

B. A 1994 Toyota Camry XLE that I kept for 13 years and 200,000+ miles

C. A 2007 Pontiac G6 convertible that I currently own and have 108,000 miles on it.

In the first year of ownership, the GM product had more repair work completed on it than both Japanese cars combined.

no solution. it's a front crankcase seal leak. replace it

Now they say its a coolant leak. I keep adding deck coolant and it is a small leak in the beginning. But I don't have $1,400-$2500 to fix the problem

I was looking around inside the engine compartment after topping off the windshield washer just for the heck of it and I noticed what looked like oil on the cross member/motor mount area. I got a brighter light and sure enough..... oil. Crawled underneath and it was on the frame work! Checked out 3.5L Pontiac engine leak problems online and found numerous references to front seal leaks! 24000 miles and it looked like it leaked worse than my 03 Silverado that had 85000 miles on it! I have never seen any oil on the garage floor. What a bunch of crap. I bought this car new.
