92 motor is sick!!!

[wildwestdiesel]

I cranked up my 92 motor after sitting for a very long time and it blows a lot of white smoke!! What should i do? It ran good gefire it was parked about 18 months ago to ndergo a restoation project but now it run bad. I put fresh fuel in it so that aint no problem. the smoke comes out of the turbo in pulses as though it is only coming from one cylinder and the motor shakes like it isn't firing on one whole. I let it warm up and it didn't help. Now I need help! Has anyony seen this and what were the remedies? Thanks in advance.

Sitting for a long time is probably worse than running the whole while. Most likely you have a gummed up injector that will respond to some sort of clean out/conditioner fluid. Get some conditioner and make a strong proportion mix. Rig a line so you can attach to the lift pump and burn that through the engine. I have used a gallon or two gallon container that I SECURED under the hood on the driver side next to the inner fender. Then attach a draw line to the lift pump. Prime that arrangment and purge any air. You can then drive the truck to get everything to temperature with the heavy dose of conditioner. Recently did this on an engine and cured the problem.

was yours smoking like this?

Well, smoking like what? I can only imagine what your smoke looks like. I don't know where you are located so don't have a clue as to how cold your are at your location. Is your manifold heater functioning as it should. There are after all some several things that you should check out before you get to thinking that your baby has died on you.



But, from many years of servicing diesel equipment from all the manufacturers, my first impression from your description is that you have a sticking injector/s. You can tell for sure if it is only one cylinder by LIGHTLY touching the manifold at the head port of each cylinder to determine if each cylinder is fireing. With the turbo, it harder to tell after just a little running as everything warms more evenly than if you have unobstructed exhaust. You could certainly have more than one cylinder that isn't fireing up. I have on occasion removed the ehaust manifold to know for sure. I am guessing that you do not have considerable experience servicing these engines as what you are describing is common enough,-- and certainly fixable.
