I just bought a 1994 full size Blazer 4×4, 350, and a 5 speed. No pictures yet, I'll add them when I go pick it up.

The good: only has 164k on the clock, no leaks underneath

The bad: needs a clutch, needs a tune up


I need some suggestions for a good replacement clutch and flywheel?

Those old TBI motors don't make much power. Just get a stock replacement from the parts store or online.

Will do, thanks Josh. Also, with the clutch slipping this bad, I'm planning on replacing the flywheel while I'm in there, along with the rear main and pilot bearing.

External or internal slave? Might as well do the throw out bearing too

I haven't been under it to verify yet. I'm planning on clutch, flywheel, rear main seal, pilot bearing/bushing, and throw out bearing while I'm there.

Just got it back from getting the clutch, flywheel, pilot and throwout bearings, and rear main seal all replaced. Drove it home from the shop and it's very cold natured upon initial start up, has a very large exhaust leak, and I believe has a stuck thermostat as it was above 210 after driving it 15 minutes at 65.

Current plans are a tune up, oil change, and get the AC back working and drive it.


It's a 1994 Blazer with 5.7L and a 5 speed manual with only 164k on the clock.

Mannnn I want it!!
Everything is for sale for the right price
So far, I'm liking this one. I missed driving a standard. This was the second one I found fairly close to me with a stick, first one sold before I could go look at it. It blows my mind what some people are asking for these blazers and 2 door tahoes!!! Gonna keep me busy for a while and will let me get my son involved in working on it.

As you can see, it got a little warm on the short drive home (15 minutes at 55-65 mph) last week when I picked it up from the shop. From previous experience with this generation truck, I know they have a tendency to leak coolant at the intake manifold gaskets when they sit for several days.
The plan for this week is to do an oil change, plugs, wires, distributor cap, and rotor, and a new thermostat. Also, gonna order some vent visors as it currently doesn't have working AC and it gets pretty warm down here in south Louisiana

The vortec motors are the ones that tend to have leaky manifold gaskets. The TBI motors didn''t really suffer from that problem.

Tha k you Josh, that's good to know. I will just plan on replacing the thermostat and make sure it has a good cap and go to the next item then.

Not sure, but t took a picture while I was under it this morning trying to find an exhaust leak. Also, after filling it up I found the fuel filler neck is just barely connected to the fill hose and the vent line was completely disconnected.

Thats an external one. internal would have that bolted on part inside the bell housing and no way to pull it off. so lucky for you, its just a matter of 2 bolts and a line fitting

That's good to know. I'm gonna assume it has an NV 3500?
