Hi Guys, back again for some advice.....I just purchased an '87 Brougham, really nice shape, it may have only 29k miles, but I'm unable to determine if that's accurate. The car has sat unused for much of it's life. I know often that's a big red flag, but it ran well, drove good, and I couldn't resist. What my problem is, is that I drove it about 200 trouble free miles, excluding the shrieking fan belts, which I've ordered online to replace. Started right up, idled smoothly, braked well. I had the oil changed, and added i can of seafoam to the tank. I drove about 15 miles, got it on the highway to help burn out all the carbon and junk, and before leaving the highway exit, it started running rough, I got off the highway, and it was really running rough with a very rich smelling exhaust. I brought it to the local GM dealer, they looked at it the next day, and came back with no compression on the #6 cylinder.....all others were fine. The diagnosis was broken valves on that cylinder, and was told that was a common problem on these 307's, and the mechanics opinion was these engines were junk, and the Chevy 305 was a much better engine. I was quoted $500 just to tear apart enough to ascertain this is the problem, and about $2000 / upwards to repair. Needless to say, it made me sick, I lost some sleep, and also the mechanic offered me $700 for this nice car. So after several days of thinking this over, I'm thinking of selling the car for parts or fix, but wondered, what if it's only a sticking intake and/or exhaust valve, and would I dare get into the engine myself, and remove tons of wires, brackets, hoses, and whatnot, remove the valve cover, and check for sticking valves? I'm sure some of you guys have experienced this problem! Any advice? I really do like this car, it's in my mind the CLASSIC Caddy, and I would like to keep it, I just can't afford to sink a fortune into it....I know that's every car lovers dilemma...any advice or input would be greatly appreciated, I'm having it towed back to my house in a few days. Thanks, Bill
