I sold it to my uncle who ran it for a few more years. He sold it to a lady friend, ran it for a few years, who then sold it to someone else. That was either a good engine or a good oil. Everyone tells me that it was neither... only luck.
It wasn't luck....Chev. 2.8 V-6's were great engines that went for miles.
Seen a few that took a licking and kept on tickin'..........
Yes. My mother gave hers away @ 210k due to UV damage to the dash and the headliner being shot. Used M1 from just about new for 1 year changes. The internals weren't clean, but the engine was quiet and only consumed 1/2 quart between filter changes @ 7500.
They geared it very well in the X-body. Strong running engine in that chassis up to about 80-85mph.
Other than being a somewhat ugly duckling, it was one of the best cars my mother ever owned. I flogged that thing relentlessly without thought. Only major component to fail was the bike chain in the trans. It stretched at like 180k or so, iirc.
