Someone removed the heat riser from the exhaust manifold of the engine in my '50 F1 and put a spot of weld on the hole to close it up. A friend of mine said he didn't think it would affect the operation of the engine unless I planned to drive it in the winter. Any comments? Also, are there any vendors around that would carry the parts if I wanted to replace it or do you have to search for used parts?
Are you talking about the big flapper-door thing in the exhaust flow connected to a bi-metal spring that opens as it warms up? You could very likely find a new replacement, but it probably wouldn't bo concours correct, if you're concerned about that kind of thing.
As for operation of the engine, do you drive it now, as is? If so, how well does it start and run currently? It certainly won't hurt anything to run without it.

Yes, that's what I'm talking about. I'm not concerned about concourse. I probably won't be driving it a lot when there's salt on the roads but I would like it to run right in cold weather.
I only drove the truck in and out of the garage a couple of times before I started disassembly. It ran very poorly at that time. The carburetor needs to be rebuilt and as you can see from the avatar photo, when I got it it burned quite a bit of oil. I'm getting the engine rebuilt.
On my 48 226
my heat riser I broke the shaft off the spring when I first got the truck
so I took the exhaust pipe off and tapped closed the gate (always closed)
I have no problems with overheating in summer
or too cool in the fall or spring

Sorry to bring this back up, but I can't find where this question was ever definitively answered...
When the heat riser/flapper counterbalance is in the horizontal (9:00 oclock position) does that mean its open or closed?
thanks
