83 chevy 6.2 Diesel smokes!

should I fix, ls swap, or fix and add the 6.5 turbo set up that I have for it????

Mine behaved exactly like this. The cause turned out to be stretch in the timing chain. I advanced the injection pump timing, which entirely solved the smoke issue and returned the engine to normal.

My ‘84 K2500 diesel (bought new, now at 275,000 miles), recently started blowing some white smoke. Turned out to be a faulty thermostat. I replaced the thermostat with a Gates 190 degree and the smoke stopped.

I'd do a compression test and make sure you're not throwing parts at a bad motor. I would keep the 6.2 but i'm an IDI fan.

I am an IDI fan as well.

Go through all of your fuel lines make sure there is no leaks those rubber lines will break down after a while. You can run a clear hose off the injection pump to see if you have air in the system. Usually will be no fuel in the hose when it sits if there is a small leak even the slightest leak

It comes down to two things 1. Head gasket on driver side is bad or the timing of the injectors outing fuel in piston at wrong time and comes out as smoke. In my book it says blue smoke is caused by unburned fuel

[@slipknot87666543211]

try changing the lift pump or test it using a low pressure electric gas pump to see if the lift pump lost pressure

[@brandonm.6604]

I’m pretty sure you have a cracked ring on the drivers side bank. The one side smoke is a dead giveaway. I had a 454 that did the same thing. Smoked real bad out of the passenger side. Did a compression test and saw that cylinders 4 and 6 had a low reading.

[@partmaker55]

Probably a mix of both oil consumption and an injector or a few goin bad

[@jessemcgee912]

I got one that doesn't smoke on start but going up a steep hills at higher rps blueish smoke starts coming out the passenger side pipe first then driver side what do you think it is

[@rank1154]

Did it smell good. I love to smell diesel smokes

[@Victorsvolkswagens]

I have a 6.2 with bad injectors trust me you don’t want to smell that 😂 I still have a headache from starting it 4 hours aho

[@aaronpohl767]

"Smokes my neighborhood" 😂😂 hell yeah

[@sheendean4802]

He says “it doesn’t smell like coolant or anything.” Me thinking - “Okay that’s good” He then says “But it burns my eyes…”

[@MattsMadnessOfficial]

advance your injector pump that will help a lot

[@v8felon]

This insane 😂 please let me know if you fixed it

[@mr._gator1284]

Looks like you might have an air intrusion issue

[@travisclark2346]

Fix the diesel that’s in it

[@a.jansen589]

That smoke must have smelled good, delicious. Too bad it was so little, it could have been a lot more. And as long as it smells so good, the amount of poison doesn't matter a damn, as long as it comes out and a lot!

[@staym925]

Seams like need to adjust time of injection pump.

[@3miller]

Put money into the engine the Detroit's aren't that bad if anything LS swap it don't Cummins swap it

[@jimjenkins3226]

decent shape ? 😜 I live in Atlanta so what do I know.

[@ESLinsider]

Did you fix it? Am thnking of buying a 6.2 step van that smokes like that and wondering what the problems could be heard of bad fuel, fuel filter, injectors, headgaskets, etc.

[@brentdavenport4214]

I changed out with known good injectors and nothing changed.

[@brentdavenport4214]

I wouldn't get another 6.2. Gutless wonder.

[@streetspeed7659]

Have u found the issue my 6.5 does this

[@finnmafa6257]

Change the injectors.

[@brentdavenport4214]

I did with known good ones and no change

[@Captain-.James.-T.-Kirk]

Are all the glow plugs good?

[@liamthemarchingbandguy4063]

With the smoke it’s blowing out it probably has a blown head gasket. You should Cummins Swap it
