February 20, 2006I own a 1995 GMC full size pickup. 150,000 miles. Runs great original engine, transmission, etc. It is leaking oil and the dealership says it needs the following replaced: Intake Gaskets $400, Valve Cover Gaskets $155, Oil Cooler Line Seals $80, Timing Cover Gasket $515, Oil Pan Gasket $360, Power Steering Pump $305, and the Rear Main Seal $600. Ouch! I just had some gaskets replaced by my parents excellent mechanic who live in FL (oil cooler lines and oil pan gasket and something else). I cant sell my first vehicle (my dad got it new in 95). It runs fine... the only problem is the AC doesnt work and it leaks a little oil wherever I park it. Any suggestions?

February 23, 2006First change your PCV valve, and make sure you've got plenty of vacuum going to it. A clogged PCV will cause oil to leak out of your engine from everywhere. After this is done, get yourself some type of engine cleaner, like Gunk or Simple Green. Clean the engine thoroughly, and I mean thoroughly. Then run the engine for a while and see where the leak or leaks are originating from. Then just replace those gaskets or seals. I doubt very much you need all the work theyâ€™re telling you. Maybe itâ€™ll turn out to be something small, like just having to snug down the valve cover bolts a little. Another thing, there's this stuff out on the market from a company called ATP. It is part number AT205. It's a re-sealer additive that rejuvenates old rubber. It works very well. Iâ€™ve used it on a few vehicles so I can vouch for it â€¦â€¦
