My 4.3 has almost 300,000 miles on it, still runs great, doesn't burn oil, and doesn't make noise. It's quite possible the most simple, basic, and reliable V6 available...

Lmfao, “...Pelosi you fucking witch!” Agreed!!!

4,3 one of the best built Engines almost #250.000 miles on my 1997 astro van!!! Thanks for Sharing!!!!

That engine has been apart before. Looks like a Dorman timing cover, which isn't bad. The plastic timing cover on these engines is supposed to be replaced every time it's disturbed. Another thing, these engines are externally balanced. The harmonic balancer is a neutral balance with a weight pressed into one of the holes in it. You need to tap that weight out of your old balancer and tap it into your new one. Be sure to tap it into the same hole on the new balancer. I put a little JB weld on mine so it won't come out someday. Its possible that the aftermarket balancers come with a new weight already installed. I have 2 brand new GM balancers, neither one has the weight installed and they didn't come with a new one.

7mm socket would of taken the studs out before you rounded them off

My 1988 S-10 had a 4.3 with TBI. Ran great and lasted almost 200k miles. I sold the truck to a friend who used it for a landscaping business. The TBI was easy to work on compared to the other intakes, but not the most powerful. The best bet for those who want power is a carburetor adapter. Holley made one and it isnt' expensive.

my other 4.3 s10 1996 has 750,000 miles and runs good stock everything. my other s10, 2000 i replaced the heads with 400,000 miles runs good. my zr2 1999 s10 still runs good 300,000. sea ya next season son

The goop is probably from running Pennzoil. Pennzoil includes wax/paraffin wax or at least it used to. It builds up over time from the engine getting hot then cooling again & getting hot & cooling again and again and again. I found the same goop & more in my double hump 350. It helps for a more smooth mechanical operation but builds up in the corners and where oil sits. That’s what I know to be true from my experiences anyway.

These guys can't remove a 7mm stud and they expect me to lend credence to their advice and opinion on Chevy engines? The one dude that sounds like Marge Simpson's sisters is particularly intellectual...

The dude filming is hilarious 😂

Homeboy sounds like the ghouls from fallout

I want the sidekick to add commentary while I work 🤣🤣🤣😂😂

Old boy said harbor freight was best kind... And he wasn't lying

Lol.this is like trailer park boys.

Mine had the same lifting Peck and knocking tight noise thanks guys for the video I know now what to look for

These guys, they are special in a way

Here is a teachable moment...at 8:57 , removing a threaded stud with vice grips, If you flip the vise grips over they will ALWAYS bite better. You pull toward the moveable jaw, the opposite of what you did. Same story for pump and Channel lock pliers, all adjustable wrenches and of course, pipe wrenches. If you doubt me, you haven't tried it. Saves a lot of aggravation. Does anyone know of aluminum heads and intake for these engines?

If you look really close, you'll see that Briggs & Stratton manufactured the balance shaft.😀

You guys are halarias. Great video.

Can some one pls help me I’m trying to figure out how to adjust the rockers on my 4.3 engine

One think them engines are bad for is getting a tick from the rear exhaust manifold bolt breaking off. Happens on a lot of them and it sounds damn near just like a valve tick

Mine also has a weird knocking noise, getting ready to pull it out. Mine is in a boat 1995.

Mother love bone in the background 🎸

Instead of vice grips you could used a socket

Couldn't you have used a socket on that stud

If it ain't broke don't fix it fellas

How’s the engine rebuild holding up?

Is this a video from the 80's ?

Ha ha ha he said pump the lifters by hand

So some idiot while changing the intake gasket left one of the rags he used to cover the holes from debris in the hole and put the intake back on. So finally found this out because we can see the rag in the cylinder when we took out the spark plug in cylinder one. And by idiot I am talking about myself. Please tell me you have a good idea at how to get that rag out.

These 4.3 vortecs are super easy to work on 10 minets later map gas hammer vise grips pure will

Exhaust tick, they all do it at around 120-130k

I keep. Owing across this guy and this v6. Please no one let them work on your cars

I know this is old but my 2002 Chevy s10 4.3 vortec a bolt dropped into number three so the header came out almost like butter the intake out but I got 6 bolts on the bottom and all the ones on top of the head but it’s stuck on there am I missing something

I found those peaces in my motor to and I broke my oil pressure sensor and those same peaces came out of it

How to time a 4.3 engine

It's just a shame all the time he took to get one head off in this video.

14:04
