I bought my 87 GT daily driver with 169,000 on it. It's about to turn 210,000 now.

I've been through a couple T5s, but never had any problems with the 5.0 internals. Still runs storng. Never any oil in the coolant or vice versa. Can't feel any blowby holding my hand over the oil fill tube.

Mine has 175K and it has a little bit of a knocking sound and a hissing sound that just started about 3K miles ago.
