:iagree:about the Blazer. I owned an '89(first year for the 4.3 and non vortec) but in 100K miles I went through 2 sets of the flexible oil lines to and from the oil cooler in the plastic radiator which also broke 2 times. Went through 5 clutch fans and at the end was sitting in a hole in the front seat. Mine had the digital dash which blew it's inverter power supply twice and would have cost a pretty penny to repair/replace if I had not hunted them down in a bone yard and done it myself. A bird noise somewhere in the tailgate used to make me want to push it over a cliff, and when I sold it it was still chirpin' despite every effort to fix it. Also had problems passing smog tests, which turned out to be worn injectors in the throttle body injection system. There are 2 of them and they are expensive!
