238/80's smoking on cold start
Curious if this is common.
Got a set of 238/80's that smoke on cold start, until eot reaches like 140-160. Then as if by magic perfect no smoke. No bad hot, or cold start performance and no missing. I had them pulled and flow tested, they found 1 bad nozzle and the rest were good. Reinstalled and same thing. I'm wondering if it is something internally that does not show on flow bench with fluids at regular EOT, or perhaps a tuning issue. ETA: Forgot to mention e99 truck, and auto. So as far as I know I avoid the known zf6 timing issue from factory on these trucks. Last edited by glovemeister; 02-12-2020 at 10:45 PM.

If you are talking white/grey smoke, then it is pretty normal. My 238/80s will smoke when cold, but they start clearing up pretty quick. By EOT of 85-90 degrees it is clear. How much smoke are we talking? If it is just billowing, then you may have some other problem.

I have never heard of the ZF6 timing thing. Would you explain.
I have a 02 with the 6spd.

Yes, there is an anomaly that exists but it DOES NOT have any effect when "fixed". It's a non-issue.

Early '99 had XLE4 PCM, hard to tune compared to PMT PCM's

Mine is an AWA3. I put AC injectors in and it smokes like a train when it get cold out. Smells like unburnt diesel and don't walk through the cloud or you'll reek the rest of the day.

Doesn’t help that it was run for who knows how long before I got it without an air filter.....in dry, dusty West Texas.

Heck my Swamps 200/30's smoke like mad and idle rough at start up here in Michigan. They clear up really quick once moving and idle smooth.
