How Many Miles Does Your 4.3 Have

I thougth it would be interesting to see how many miles people have on their 4.3 without a rebuild..please mention if its a tbi or vortec and how well is it mantained and last how do you drive it?

I have a 95 with the vortec that just turned over 98k miles. Only mechanical things changed were the fuel pump, alternator, the the lower intake gaskets, and the exhaust come some warmer weather. Along with usual maintenance parts.

i got a 95 jimmy with 205,000 miles on it. i don't abuse it but im not affraid to let it scream once and a while. its got its issues and i may bite the bullet and get rid of it soon.

2000 Vortech with 82000. In DIRE need of a tune up!!!

Well original 4.3 in the 91 went 169 and change.
The V8 went all of 15 miles.

1996 2 dr 4x4 190K and has had a Western 6'6" plow on it its whole life. Plow Mine and my families driveways about 5 total here in Buffalo NY. Can carry that plow up to 80 miles a day sometimes in some pretty bitter snowy conditions.

1999 4.3 Vin W 4X4, I have owned it 3.5 years. When I bought it it had 37000 on it, it just rolled over 120000. I keep up with maintenance, and it runs pretty well.

2000 Blazer 4.3 4x4, 106,000 miles. Purchased new, replaced alternator at 65,000, cat-back exhaust at 75,000, lower intake gasket, lifters and oil lines at 105,000. At 50,000 miles I had the tranny fluid changed by machine, at 100,000 I dropped the pan, changed the filter and added 4 quarts. I plan on taking it somewhere for a machine change soon. Embarrassed to admit that I used Jiffy Lube every 3000 miles from new to 75,000 miles (my wife drove the car then) and they never once lubed the front end. At 75,000 I noticed a squeak in the front end and found the problem. Since then, been doing everything myself and will need to replace the ball joints as soon as the weather permits because of Jiffy Lube's lazy incompetant a$$holes. Runs great, but I'm overdue for plugs/wires/cap/rotor since I'm still using the originals. I'm thinking about throwing in a new radiator this summer too because of BlazerLT's post.

'95 Blazer LT 4.3 Vortec
Did regular maint. and crapped out at 140k.
looking for a replacement now.

97' Vortec, 205,900 miles. regular maint. i baby it a little, fix what i can and when i can. i have had it for 3 years and it has been the most dependable veihical i have had.

95 vortec with 175,000

This week I am putting plugs, wires, radiator, cap, rotor, shroud in it. I did the tune-up stuff at about 80,000 - 100,000 and bought it at 76,000.

I don't believe in doing mainenance,,,, just repairs. It has had a water pump, fuel pump,gas tank, 3 sets of front brakes, 2 different swaybar links, 2 sets of tires, lots of oil and filters, a reuseable air filter

I have a 2000 4.3 vortec I do believe that they only put the vortec in the newer models..Am i Correct? I just turned 100000 last night! no huge problems replaced the alt and the oil cooling lines and regular maint. Used to beat on it, now im kid to it. Out side of the motor i replaced the front dif . That has been the biggest repair i have done...

Mines a replacement Jasper Engine with about 40,000 miles on it...... I abuse it way too much

Its a Vortec

mines a 95 i got it with 106,999.9 now it has 118,600 ish i change oil every 3000 miles myself i just today replaced motor mounts, manifold gasket, and freeze plugs as well as cap,rotor wires and plugs since i plan to take a long trip this weekend so i needed all the small itty thinsg fixed to ensure a good trip i drive it normilly and not afaid to let it scream every once in a while ... so far just as my 85 blazer was both have been good to me

I have a 96' Vortec, 191,253 miles.. No overhaul, regularly maintained, and ive put atleats 50 thousand of those miles towing or pushing 22's, or doing both... I did have a seal go on my intake manifold, but i knew a guy that hooked me up, also like everyone else i have replaced the fuel cell, and the door pins... i love her...

I have a 2000 chevy blazer with 140000 now and wheel bearings are the big thing so far but I baby it alot and hopefully it will keep up the good work cuz i can't afford to do much to it... LOL

I have a 01 with 112,000 miles on it. It runs great, I'm probably due for a good tune up. I recently replaced a wheel bearing. I also flushed the cooling system & replace it with "green".

Mine just hit 141000. Runs absolutely great, only problem I've had to date is the water pump, which I had to change last summer - not a big deal. Truck is a 1998 2-door Blazer.

I can't say I've been impressed by my 93 S-10 Blazer. I had a lot of issues while it was under warranty (30,000 or 3 yrs.). A pretty crappy warranty compared to others I've had in the past.

Right now I'm showing 100,175 miles but my odometer took a crap somewhat before 100,000 miles. It jammed solid and took the odometer motor with it. As best as I could tell based on previous mileage, it crapped out at about 100,000 miles, so that's what I set it to when I cleared the jam-up (it wasn't easy to clear since the unit is tamper-proof).

Recently, I replaced the radiator and hoses, water pump, cpi (spider and nut kit), battery, alternator, windshield wiper switch, windshield washer pump (second time), rear window struts, Odometer motor, ammeter (self repaired), oil filter-coolant line o-ring/gasket, Broken spring in drivers side door latch. With the exception of the battery, I would call these premature failures and not maintenance related.

Earlier, while under warranty, there were problems with air leaks in the intake manifold, front end suspension problems (replaced front coil springs), premature tire wear (gross one-sided wear on the front tires) which the dealer said was corrected but wasn't, replaced plug wires (really?)

Recalls of the ABS system, and LEGR system.

This seems like a case study of GM putting out a product that had great long term appeal to a loyal customer group but chose the short term in product quality. I'll bet the CEO got a HUGE bonus for selling a lot of crap and here we are today with the grand prospect of GM in Chapter 11. (or is it 7?) The money they give to CEOs could buy a lot of product quality. When will the company boards figure that out?

94 Vortec 256k+ The most expensive thing thats replaced is the EGR

89 TBI 155k has some issues, hope to replace it within 3k miles.

well my 98 pickup just turned 118000 ish, checked the oil, brought it to the shop, and the intake poped in 35 seconds of driving, but, it spewed in, so i considered her dead (machanic, work at a shop, seen what happens to A LOT of vehicals that pop inside and you flush them, its already to late for the bearings/bottum end in general) but, shes being reserected this spring with a vortec 350 to replace the vortec 4.3

I thougth it would be interesting to see how many miles people have on their 4.3 without a rebuild..please mention if its a tbi or vortec and how well is it mantained and last how do you drive it?

well, I have a 1991 S-10 Blazer with the 4.3L TBI. It currently has roughly 145,000 miles on it. It has the tow package on her, and she is so heavy and geared so low, I can't even get her to spin the rear tires if the peddle is tromped to the floor.


so..... no landspeed records will be set by her anytime soon.

I have a 1992 Jimmy (CPI) vortec, with 68,000 miles.
I’ve replaced the plugs, distributor cap and rotor. I’ve cleaned the EGR a few times, and always change the oil, about every month with a new filter using synthetic. She’s running great, although she is eating a little coolant.

Mine is an 89 Blazer , formerly TBI now much better with an Edebrock 4 barrel and intake 247000 on it . Lots of little issues but it gets me in and out of the woods when and where I want . Rob

I can't say I've been impressed by my 93 S-10 Blazer. etc. etc.

Does anybody read this stuff? Any comments? I guess it's just a monologue.

I read all of them , even all of yours . I didn't know they put ABS on a 93 model . I replaced too many things to list in the 2 years I have owned my S series . Hope this answers your question . Rob

if its eating coolent take a look at all the freeze plugs one or more migth be leaking

I have a 91 4.3 TBI with 235000 change oil every 3000 -5000 miles. The engine will probably outlast the body. Had a 2.8 with 320000 when I sold it. 93 Blazer vortec with 190000 has a loud knock not driving right now. May part it out.
