Farmall h smoking

Hey all, I have a farmall h that has been sitting for a few years. I cleaned the carb out and noticed the manifold was rusted out. I welded the crack in the intake to see if I could get it running just to move until the new manifold comes. I it fired after welding but I eventually noticed some white smoke coming out from the governor rod where it slides to go into the carb. I also noticed the smoking coming out from the plate that bolts on top that goes into the head. Is this because the exhaust manifold is blown out?

Smoking is either crankcase blowby (worn rings) or condensation (from years of sitting) behind driven out as the engine warms.

Your recent welding work is NOT the cause!

Smoking may be caused by too much fuel.
Example. When starting an engine and using too much choke you will make white smoke.

You did take the manifold off to weld it right ? Pieces of rust and slag will damage rings and piston tops

Check the water and oil and let it run 30 minutes, then reinspect. gm

Check the crank case breather tube to be sure it is not plugged.
The tube forward of the oil filter.

Old Rodney beat me to the punch. I was redoing my
iPhone CNHI parts diagram viewing process. Anyway, if
you have dirt daubers or mud wasps in your area they
love to build a little plug in the end of it. I will attach
the CNHI parts diagrams for you tractor. At the link go
to 01-Engine then subsection 012, part 6 is what you
are looking at in the location described by Rodney. If
you happen to be viewing on a phone see the info I will
add below. By the way if it is not obvious you can view
all the parts sections of your tractor from that link.
Looking at your other posts did you ever get a
sprocket for your C brake shaft? I am going to my
home stomping grounds the first week of August. I will
be going to my uncles farms where I store my Farmall
M there may be a sprocket there that you can modify
for your needs. I will try to send you an email this
evening.

CNHI parts diagram viewing on an iPhone.

The following does not apply to viewing on a PC. Since
the CNHI parts site was reconfigured in early 2022 I
have found that when viewing on my iPhone expanding
the diagram in the ..subsection preview box.. is much
clearer. On an iPhone when you choose a parts section
it shows up a list of the ..subsections.. If you select
anyone of the subsections of the list it opens all the
..subsection preview diagrams.. on a PC it shows the
subsection diagrams on the right side of the screen
due to space availability of the larger screen. On the
iPhone expand those ..preview.. boxes for clearer
diagram views. When you select one of the ..previews..
it opens default to the parts list, at the bottom you can
choose to view the diagram. Sometimes on the phone
the diagram there is so fuzzy it is difficult to make out
the ..part key.. numbers. Also holding your phone side
ways lets you see more of the site navigation links at
the top by the ..Home.. button. I also notice that
instead of going back one page, it skips back two
instead, fairly frustrating. Also generally I find it
requires some patients, response can be painfully
slow. They must have a hard time making their
software work with both phone and PC platforms. I do
not know if this applies to Android phones.
