wondering if the bad lines would cause this at all(air in lines perhaps?)



help a nwbie out...feel good about urself! :D

thanks ppl!

Black smoke is a rich fuel mixture and will foul your plugs if it is bad.
Blue smoke is oil burning in the combustion chamber, either
rings ( under load, driving or towing ), or valve guides if you see smoke
at first start-up while engine is cold.
A compression test would be a good start.
What kind of sending unit are you installing ?

[S15STYLES]

not sure i hav to get one on monday...as for the smoke i hop to be able to fix it once the truck is not pissing gas out like crazy,,,anything i ned to look for in a snding unit?

If you are belching black smoke look for a vacuum leak or check out the coolant sensor.

[bonecrushins10]

i would check the egr if you have one

change the pvc

change the plugs

change the o2 sensors if fuel injected

run some seafoam

caps an rotor an wires if not fixed by now

[S15STYLES]

[S15STYLES]

wll im weerkin on my truck today....did an oil change...does anyone know the oil capacity of a 89 4.3?.....its taken almost 8 litres and not on the stick yet? :mad:

[jusbo]

Usually it's a quart a cylinder...check then add as needed. Dumb logic I know, but there you have it.

[S15STYLES]

damn maybe its my dipstick...lol

im at 8 litres

[onthecheap]

shouldn't be more than 4-5 quarts with a new filter

[S15STYLES]

did u put the oil plug back in?????? it hsouldnt take more than 5 quarts to be full. i usually put in 4 then start it, so it fills the filter, then top it off.

[S15STYLES]

well i finnally had time to do some much needed workk on the truck...turns out the dipstick is rusted away from the engine so i have no idead how much oils in there.... and it smokes blue still a lil so im wondering if its feasible to find an engine and put it in ? might be better than messin around?...any suuggestions ? also does anyone around me here in ontario know how? hehe

[S15STYLES]

ok i know someone must know whr the oxygn sensor is? im belching black smoke and running terrible....any other suggestions?...come and help a newb out...i wanna build this truck nice!

if you do go to put a new engine in i suggest that you find a 4.3 that is/was in a full-sized Silverado or Seria(not spelled right I know), as I had to change the engine twice in the '91 S-10 I had, as the first replacement engine burnt more oil than the orginial and it came out of a S-10.

Any ways my point was if you are going to replace the engine, I suggest that you get it out of a running full-sized pick-up that still has the transmission in it, as if you find an S-10 with an engine that looks like it doesn't burn oil it, it is likely that it will sooner than you want as there is less air flow though a S-10 engine compartment than a full-size.

You will have to change the valve covers, mounts(motor & pulley), oil pan, oil pump, tbi, map senor, heat senors, fan, belt, distrubutor, headers/manifolds and probably the oil filter position on the full-size block so that it fits in a S-10, that is if you go this way. The best part of this is that all the parts that you need are in/on the S-10 engine, but I suggest replacing the sensors instead of using old ones. I belive that is everything that has to be changed on a full-sized block so it fits/works in an s-10. Take a couple of pictures of the orginial block before you start to take it apart and change over so you can make sure that you switched everything over that needs to be(might be helpful, might not be).

I have done this and it works, if you do it right.
