My wifes van 4.3 vortec with AWD has 256,000 had trans rebuilt 1 year ago because son stripped bolt putting pan back on.

most we had to do was normal maintainence belts hoses water pump radiator heater control and cv joints.

 

2002 with a little over 160k

Rebuilt tranny at 150k (right before I got it, so I don't know what was wrong with the old one), new TCCM a couple months ago.
Still has a bunch of minor problems - oil drips, brittle cables/hoses, rattles, squeaks, weatherstrip leaks, things like that. And a distributor bearing is worrying me right now

 

1995, 205k miles

 

I have a little baby Blazer. Its a 2002 4.3L with 60,157 miles

 

My 93 vortec has 173xxx and running like a lion. My old 1992 s10 (even though it wasnt a vortec but still a 4.3) had 230xxx and i sold it to my one friend and its still going but it is getting tired.

 

2005 that just hit 70,000 last week. I've put almost 6,000 miles on it in the last 5-ish months because I love driving so much, but if I would have kept the leisure driving to my girlfriend's ride instead of mine, I'd probably only be at around 66,000 right now. Since I'm really trying to preserve the life of my Blazer, I should definitely slow down.

 

My 96 Blazer has 250,000 miles on it. I've owned it since new and simply changed the oil with conventional Texaco Havoline 5W30 every 3,000 miles (religiously). I think the synthetic oils are a waste of money.....just change the oil yourself every 3,000 miles and the engine will last.

And keep a close eye on those oil cooler lines....that will blow an engine fast. I'm on my 4th set.

 

Lifetime warranty on the parts is great but, there are a few threads here on the forum that explain how to modify them so they never leak again. Basically you modify the existing lines and replace the crimp connections with compression fittings and hydraulic line.

 

96 4door 4x4 197XXX

 

97 with unknown milage. The dash including the instrument panel was replaced before I got it so Im not sure of the actual milage. but it runs like a champ!
