Excessive smoke from tailpipe with noise and knocking intermitant

[Polaraco]

Yea no kidding right I’m buried in this truck so deep now although it was a smoking deal it’s been a smoking money pit ever sense.

The harness under valve cover I’ll check it tomorrow I remember the wires pass right next to the head studs maybe one is shorting out against the threads on one of the studs Thanks for the thought ol man it’s appreciated

Somebody needs to keep you damn kids in line.

my thoughts are whatabout a possible burnt valve ? an intake valve in all of this headace iv been dealing with these past few days i noticed 1 intake valve had almost no lash could i have burnt a intake valve and now exaust is poluting the cylinders causing this? i'm lost at this point

I know it's a PITA, but the best way to adjust the valves is by the Cummins procedure. If you need it, let me know.

That’s the only way that I know of how to adjust valves is the Cummins procedure I am not aware of any other way Steve ?

That’s how I set them but I’ve never been the greatest person to adjust valves ther is usually one that is loose and you hear the tick tick noise. I have the procedure but I’m past that part I’ve gone in and loosened all of them up I think I may pull the injectors again check the copper washers, do a compression test and then if everything is good reinstall them with new crossover tubes. But what happens if I find nothing wrong then what?

You and me both. Would you believe me? I have someone else adjust valves. And I've been doing it since I was a kid. As I recall, I did a 51 hudson I had. I had to re do them 6 times for cryin out loud. And that was a straight 8!

Ok guys new update and may have found the problem truck was 2 gallons low on coolant no drips, new water pump, new hoses, new t-stat, new electric fan clutch and original radiator and cap. Also boost is slow to build and egt’s climb quick. Head gasket? But how? Coolant color looks off

Yes the machine shop magnufluxed it and no cracks and followed with a resurface. Head has been off 4 time sense I’ve owned it I’m going to do a pressure test and make sure it’s not a stupid radiator cap. The coolant temp normally was around 180 never saw it over 200 except when my water pump went bad then it got to about 220. Now it losses coolant every time it’s ran for very long and coolant them is normal unless it idles when parked this time I’ve only seen it at 214 I did put a 180 t-stat in it awhile ago
