Talking Legacy Turbo, screwy!!

I'm new to this forum, I heard about it on another sube message board, I thought maybe you guys could help me with some questions. 1st, Yesterday I was changing my oil and noticed some coolant on the ground and dripping off the brace directly behind the oil pan, not a lot but some. I checked my reserve tank it was half empty, it was full last week when i checked it. Anyway I start poking around trying to find out where it was coming from, I noticed a little pool on the top of the engine on the side of the Turbo, it was by the head gasket and I was convinced I had blown one, but there was no coolant in the oil, and it wasn't smoking, then i thought it was the heater core, I thought it was anything, but then I remembered I had put a new valve cover gasket on a few days before and I got a little rough with it, is there a cooling line that goes to the turbo that I might have knocked loose?? Or any other ideas. and another thing I noticed this Sun, drove it some of that day, after I noticed it. drove it all day Mon, and as of now Mon night everything is dry as a bone. Can't figure it out. It seemed to only do it that one time. 2nd I need new tires and when I bought the car, I was a little concerned about a humming noise coming from the rear, I took it to a shop and they told me the Dunlop tires, which I have can be loud, and when you slow down it feels like the tires because it kind of hums while stopping at a light etc. Like the huge big meats do. I was just wondering if this could be something else like,wheel bearings, or the LSD.

Thanks a lot

91 Legacy Turbo

There are two coolant hoses going to and from the turbo but I don't believe either is routed on top of the right head( it's dark or I'd run out to check). The quickest and easiest thing to do is have the coolant system pressure checked. It's like a pump with a radiator-type cap that pops on the radiator. Most garages have them. Then you just pump it up and wait and look around VERY closely for any small pin hole leaks. Also, if the car has over 60,000 miles on the original hoses, they need to be replaced ASAP, and not just the radiator and heater hoses, ALL of them. It could be other things, but like I said, this is the first thing I'd do.

As far as the humming noise goes, find a place with a lift and get it up and get the wheels spinning. If the sound is still there, you know it's not the tires. A good tech could usually pin point if it's a wheel bearing, CV joint( not likely in the rear), or something else. Hope this helps some.

I can relate to the noise from the rear of your Legacy, my '92 turbo had Eagle GT+4's mounted on the stock rims when I bought it. A friend who works as a service manager at the Chrysler garage told me my noise was from the rear tires. I took the car in for a 4-wheel alignment and sure enough, the rear alignment was off, hopeing the tires would eventually wear themselves quite again, but no such luck, 3500 miles later and still the same noise I was beginning to worry it may be more than just the tires. Two weeks ago I installed my 17" Speedlines/P-Zero's, no more noise! Turned out to be the tires after all. I hope your noise goes away as easy as mine did :-)
