Ford 6610 oil/ engine issue

mikewood869 · Nov 6, 2018

To make a long story short (pre-startup to what I'm doing), anyone know why oil would be coming out of the exhaust manifold and possible coming out of the stack (I can't smell whats on the stack)? Over the summer the head gasket and the valve cover gasket were replaced and last Friday all of the injectors were replaced. If memory serves, the exhaust stack and the exhaust manifold were dry but not today. The tractor is down oil too (when off and has been sitting should be over full, but when running, should be under "u" or the first "l").
Sorry for the photos being upside down.

It's likely "wet stacking". Make sure it's got a hot thermostat in it, and then take it out and work the snot out of it. Report back.

I haven't noticed when running the 6610. I've been running the tractor for four days around six to eight hours max around 13 hundred rpms on a wood chipper and the tractor hasn't been getting hot. Today I ran the tractor for 1 1/2 hours before I noticed this and started looking.

Joe Wa - "Hi Howard, wet stacking is the result of running a high compression engine with a low load. The marine term is "slobbering". The problem is insufficient firing pressure to seat the rings and pumping oil up into the exhaust manifold and stack. Talk about the temptation to commit murder on the high sea. Been there, retired chief engineer, Joe"

This is really not oil but some of the heavier components of diesel fuel. As they say it is not being worked hard enough.

I just got to find something for the tractor to do. The biggest things I could see are baling or woods mowing (both are 90% for this year). The tractor isn't working that hard when wood chipping (only if it hits something big

Bottom line is that wet stacking, a.k.a. slobbering, is more of a nuisance than anything else. It will not harm anything other than the shine on your paint job.

My Ford 2000 diesel slobbers also. I do not let it idle for more than a minute or so (if necessary I just shut it down), and I always work it at least at 1500 rpm. Probably because of the thickness of the oil during cold weather, slobbering seems to be less of a problem during fall and spring.
