93 factory turbo idi white smoke

[Schuler73]

New here and in a pickle about this idi I've just picked up.

Anyways, just got my 2nd factory turboed idi with 180k on it and a 5 speed. The guy I bought it from put brand new Injectors and return fuel lines in it which I have the receipts for. It has a horrible time starting in the morning and like today during the day it was 54 out and still took a while to start. It smokes white pretty bad whenever it's idling and has a miss. At high rpms too it smokes a bit. I took a look under the hood and noticed my fuel filter is leaking out the bottom and the smoke smells like unburnt fuel. The ip was not replaced so I'm figuring I either have air in fuel somewhere or the ip needs to be timed. Also took out the cdr and cleaned it and put it back in. It smokes pretty bad and I really want to get this problem solved. I have an appointment setup next Tuesday with my mechanic to see what the problem is but I figured I'd try this first before I spend big bucks.

These are the best places to start. Get a new filter first. They make one that has a built in water seperator that doesn't need the bottom piece that is prone to leakage. I think it's Wix #33417

Welcome to OB!

It's fuel related; generally either a shot injector(if it has a miss/roughness) or more likely really retarded timing due to the IP being worn out. You can advance the timing to get it working "OK", but you'll probably end up replacing the IP and injectors sooner or later.

How do you advance the timing on it? I'm guessing not by turning the pump up.. but I don't think it has the stanadyne pump cause I took the cover plate off to try and turn it up but it looked like there was no keyhole to turn it up it looked like there was another plate to take off. So I'm not sure if this is the stock pump

Does the white smoke go away after it warms up?

No it doesn't

Welcome to the forum. What happens with injector replacement and not replacing the injection pump you end up with timing that is retarded. The pump is probably original with 180,000 miles on it. Usually they are well worn out around 125 to 150 thousand miles. Now new injectors in and they pop at a much higher pressure than the old ones did. So the timing gets retarded. To advance the timing you loosen the three nuts around the pump case that are 9/16 hex nuts. the top one is easy to see. the drivers side and passenger side are tuff to see because they are under the lip on the said of the pump. We use a specially made wrench to reach them too. The pump must turn towards the passenger side of the truck to advance. Move the pump about the 1/16 inch or the thickness of a dime. NEVER move the pump with the engine running. The pump is trying to make about 1800 lbs of pump pressure so it will resist turning if the engine is running. Tighten the nuts and test run the engine.
