Hello, I "recently" rebuilt a Ford 9n engine. I put new rings, a new piston (it had a chip where the ring go in),new bearings,new seals,and new spark plug and wires. Its basically a new motor.It ran a little rough so fune tuned the timing and it runs a while lot better, but it blows white smoke. Now this.engine hasn't ran in 20+ years so i don't know if its just part of the "new" parts adjusting or somethig bad. This was a test run so there wasn't any coolant to leak into the head and the gasket is new and i checked to make sure the head wasn't warped(it wasn't). So idk if my mixture is too rich or what so if yall could help it would be much appreciated. Thank you :D
 
white smoke would indicate it is getting coolant in one of
the cylinders.

If it was black smoke. Then you would have a carburetor
problem.
 
If you ran it for more then 5-10 minutes with out coolant you over heated it big time and that can cause MAJOR problem and with all that stuff new very MAJOR problems

No it.was for like 30 secs at the most at idle..i got it out back together today so i could put some coolant in it so i can truly try it out. I'll keep yall posted.
 

I hope it works out, and please update the forum with your results after you put in coolant and try it again.

I'm curious as all get out as to how there could be white smoke with no coolant to make steam??????

Maybe you simply burned off condensation in an exhaust system that was laying around while you worked on your engine????

Can't imagine any source of water/steam/white smoke without coolant.

Good luck.
 
30 seconds wasn't even enough to know what is what. Smoke in that case could be simply condensation or oil or who knows what

Yeah, who knows. It isn't a test that I would want to run in order to find out, either. Maybe it was just the packaging/protection oils burning off of all of the new parts. If there wasn't much of it, the smoke could be perhaps light colored and look like coolant steam.

I do know that strange things can happen when an engine is initially fired up that don't translate to big problems later on.

I replaced the motor in my commuter car over Christmas break last year. The motor that I bought was a salvage motor removed from a car and tested at the salvage yard, then put in their stock. It sat for two months in my garage while I waited for the time off to do the job.

The first time I started it, it sounded as if a bunch of angry woodpeckers were confined in the valve cover. After about 15 to 30 seconds; it stopped.

I figured that the valve train oil had probably dried out a little from sitting so long, and it took a while for the oil pump to get oil up to the head.

In hind sight, I think that I should have either removed the ignition wires or disconnected the fuel pump and cranked the engine with the starter for a minute or two in an attempt to get the oil pump to do its thing before allowing the engine to ignite and run.
 
If it had been a engine I had messed with it would have gotten some ATF in the cylinders before I spun it out the first time that way nothing would have been dry
