yup 20mm. I have all the above. what do you guys think of my hypotheses of why its smoking. I cant catch it to get a smell of it. it never last long enough to get out and get a smell.
bulletproof or delete the egr cooler? no emissions here where im at. my srl from matt always keeps valve closed anyway. I havnt pulled the egr valve out yet to see if any moisture in intake.

Do you have a CCV mod? With the little bit it's smoking it may be hard to tell by pulling the EGR valve. It can get oily in there, especially if the EGR is closed all the time.
I have a small block Chevy powered Jaguar that came from Georgia, the Car Fax showed it passing emissions from 1986-96. Do they exempt truck by weight over there? Certain counties exempt? I'm thinking the only reason to pop the $ for the bulletproof cooler is to be prepared if there's changes to the law. I went with the bulletproof cooler so I could sell my truck anywhere with no "complications". Now it's looking like I may keep it for a loonngg time

no I don't have the ccv mod. I do know that there is oil in my intercooler. so maybe it just needs to be cleaned out. if the cooler was leaking and a few drops ran out of the cooler into the exhaust it would run back into the exhaust manifolds then burn in there. is my thought. I guess it could be a toss up without knowing if its coolant or oil that's causing the smoke.
as far as the emission testing. im not sure how they do it because im totally out of the loop because my county does not do any testing for any vehicle.
I think im leaning towards the bulletproof cooler than a delete.

just went out and pulled egr valve.. its full of black crudy stuff. last time I pulled it it was all black but was not this same type of crumbly cruddy crap.. ill take a pic and try to post good news is that there was no woosh of coolant going into intake. valve is a little damp though.

Doesn't look too bad. Maybe a little oily but not wet. Going to be hard to chase this one down with how short and little it's smoking. Could be an injector also. Would be great if you could get a wiff of the smoke....
I am a little surprised there's that much carbon under there with the valve closed by the tunes. I guess it's still open to the exhaust through the cooler but being a "dead end" it seems like it would be cleaner.

how can I test the injectors. I just noticed Saturday that I have one sticking until warm. the smoking I have been seeing has only been seen after driving for 30 to 45 minutes. I don't ever see smoke at startup.
I had posted this issue back before it got warm in the spring. I havnt seen it the whole summer. the other day it was a good bit cooler outside that morn. in the upper 50s I think.

A redneck way of checking for problematic cylinder(s) would be to loosen all exhaust manifold fasteners, to pinpoint the cylinder(s) with smoke exiting the exhaust ports.

To check for weak/non firing injectors would require use of IDS to monitor power balance during cold engine start up (with weak cylinder compensation strategy disabled) and while under load when the miss occurs.

m-chan, any idea what it would cost down here for the dealer to do a test. although wouldn't be a cold start test for them unless I left it with them.

I don't know what the hourly rate is in your geographical location, but I would surmise between one to two hours of the going rate would be my guess. And yes, to pinpoint a "sticky" injector(s) would require having it sit overnight cold soak before checking with IDS using the method previously described above.
