160 degrees on a C-123 block! :)

On another note I have to pull my head again. Either I have a bad valve stem seal or one of my valves is leaking for some reason. Weird because I just worked over this head myself and installed new stems, valve, and all from one of the kits available from this site.

While I was running one day I noticed smoke coming out of the oil filler/breather pipe (tube on valve cover) and chugging in tune with the exhaust!!!! HA! Imagine that! :)

I keep on having little troubles with this little 100 but man I sure do love it! Working out the kinks on this thing is a sheer pleasure!!!! :)

HAPPY EASTER GUYS!!!!! !!!!! !!!!! !!! :)

I hate to tell you but the "chugging" of smoke out the crankcase breather is MUCH more likely to be sneaking past a piston than past a valve guide.

Fantastic!!!!! Thanks for the reply! I was kinda curious as to this :)

As long as the coolant isn't boiling; you're not going to hurt the engine. Getting the temp up into the 180 to 195 range is BETTER for the engine than running cold.

You're right Bob! I forgot about the bottom end! It could be possible I broke a ring. Hmmmmm?
Now I did do a compression check the other day and got 90psi across all four. I didn't do a leakdown check though.....Guess I need to do that tommorrow. :)

Yep I know it needs to be hot to maintain combustion but I wasn't sure what the parameters of this cooling system were. I wish I could find an IH specified temp range for this little engine. :)

As long as the temp stays below the point where the coolant will boil in "hot spots" in the engine you aren't going to hurt the engine; and the engine will probably burn cleaner AND last longer.

That pretty much applies to ANY liquid-cooled engine.

I'm gonna do a leakdown test then go ahead and pull the head and see what I have going on in there. I'll drain the oil tommorrow and run some deisel in the crankcase to clean it out and then see what we can see.
