Tractor
International 1066 Full sized JCB Loader/Backhoe and a John Deere 430 to mow with
International 1066 though, I wouldn't think that would matter.

Dropping trees with backhoe then dragging them to burn pile with 1066. Leave one machine idle while using the other. I start noticing "bleeding" down exhaust stack on 1066. I think I've finally figured out what people are talking about with slobber.

Someone said it's a temperature thing, restrict flow through radiator. Did that but evidently not enough! Machine is essentially just idling through this process however, when I pull the (full) tree,I do up the RPM's and it blows some smoke out the stack until that clears BUT, the temp is still riding "C".

So this isn't really "work" for the tractor and it slobbers. Got me wondering.... Just to be black/white..... if this was a NEW tractor with factory spec engine operating perfectly...... would it still slobber under certain conditions?

If so, is this (today's) slobber worse because the engine has ??? hours on it? (I bought used so no real idea BUT it does emit blue under the engine out the (breather?)

This artic spell has kept me from pulling any more trees which is fine because I hate the cold AND that would only make the engine MORE cold! Any ideas how I can "work" the engine harder to minimize this when I go back to finish up dropping the trees? (pushing the woods behind house back so any tree that might fall can't possibly hit house)

ZERO signs of slobbering from (JCB) backhoe yet easily discernable black dripping down exhaust of 1066. Same conditions, both doing a lot of idle. Why so evident with one and not the other? (brings back to my 'factory new' engine..... I'm wondering if that's an indication that the JCB/Perkins might be in better overall condition than the International)

wet stacking. This is the accumulation of unburned fuel, soot, and condensed water, which leaks out of the exhaust joints and creates a black, oily, or gummy residue.
(AI)
happens on most diesel engines. personally, i shut off engine if left over 10 min of idling, thinking you're overthinking on the rebuild, you have a great old school tractor(s), regards

If engine isn’t getting warm I would check to see if thermostat is working since temp gauge should move even idling or at least our tractors from that era did.
