Goodwrench crate engine smoking from passenger side exhaust

Compression test,disable ignition by pulling the coil hot lead at the cap. Pull your plugs crank at WOT until your gauge quits climbing write down results. That's dry, Put a little oil in the cylinders 1 at a time and repeat your test,that's wet. A wet test will generally help determine if it is a ring problem.

I wouldn’t spend 5minutes on the carb and other stuff until I knew if there were major issues or not.
Compression test is too easy to not do. If you don’t have a comp tester, or the money or need to buy one, get a loan a tool one.

 

[Ricko1966]

Buy a compression tester. One with a removable hose,because next I'm going to teach you how to pressurize the cylinders to diagnose low cylinders.

I’ll get access to a tester. I’m not sure on the carb but I resealed and cleaned out one of my other quadrajet as and I’ll try to throw it on and atleast get it idling better. It fires right up and runs great off idle. It’s got a massive vacuum leak at the base gasket currently. Could absolute loads of fuel going into the cylinders cause the whitish smoke?

PLEASE STOP SCREWING AROUND WITH THE CARB AND DO A COMPRESSION TEST!!!

It’ll have to be tomorrow afternoon before I can if I’m even able to then. I did the other quadrajet because I want to go back to a qjet on my work truck. I didn’t get off work until an hour ago and it was already dark plus it’s raining a little bit here in Tennessee.

I would give you a hundred and 30 likes for this if I could.

I get where he’s coming from, but the qjet I cleaned wasn’t for this truck just figured later could throw it on. I’ll have the tester this afternoon to get some compression readings. #1 has compression verified from the finger test but that’s as far as I got.

 

[MrHorsepowerLSx]

The finger test proves nothing for diagnosis. It could be 20psi and feel like a lot of compression when it blows your finger off the hole. Just report back to us when you start getting some numbers

 

[iamtherealJayy]

Had plans to do the test tonight but work truck took priority since I received my new distributor lol. I hate it getting dark so early

This is a dry test just cranking cylinders. Could be some gasoline in there however. I did notice a few plugs were soaked with fuel. Truck has been sitting a week now. I redid the gap on all the plugs to .037 as I couldn’t get 35. I noticed one was way open on the passenger side and one was almost touching on drivers side. I didn’t bother a wet test since they all have compression and mostly close to one another.
Edit: yes I know #2 plug is different. I broke the original champion plug that was in it and just threw this acdelco plug in out of a different engine. The problem existed before the plug was different.

 

[iamtherealJayy]

Actually I stand corrected. I forgot a step in the compression test. I did not hold it wot. How much difference does that make

 

[iamtherealJayy]

I googled it and it said it won’t make a big enough difference all it does it let more air in and I was mainly looking for a dead cylinder. They all have compression within 25. With one being highest and two/six being lowest. What do I move onto now since it’s got compression? Now can I touch the carb lol?

The wet test is important. You should have done it at the same time. Crank to max pressure, then squirt some oil in there and repeat. It looks to me like that engine is old and tired, but probably has enough to run OK. You need to put a new set of the correct AC Delco plugs in there and properly gap them. I would bet that the rest of your cylinders would come up close to the 160 during the wet test... would would tell you that you have worn rings on 7 of 8 cylinders.

Also, the way those plugs look makes me think you might have an intake gasket leak and it's sucking in oil and fouling several of those cylinders
