White smoke and now motor is locked up

[chas427fe]

Thanks everyone for your replies. I just left the garage and the last little bit of oil was draining from the oil pan. The oil pan had nearly 2 gallons of antifreeze mixture in it before the oil started to come out. Tomorrow I will try to pull the plugs if I have time. I have a busy week ahead so I don't have much free time. I am still trying to decide whether I want to tackle this or not. the last times I pulled apart any engines they were a flathead V8 and a Chevy straight six with poured bearings. I guess I am dating myself.

Back to the questions asked: the compression ratio is 10:1. It has side pipes with no crossover. The last rebuild was less than 10k miles by Keith Craft. It has run great until now. I do get on it now and then, use it but try not to abuse it. I have not had it above 6K rpm. I did have heating issues at the beginning but they have been pretty good lately.

Olddog is spot on. If water was in both pipes, you blew the head gasket. I know from experience that the geared starter motors can bend rods when hydrolocked.

I think you mean intake manifold gasket.....

My bad. Intake gasket.

I got to thinking about this statement after I went to bed last night. Was it really 2 gallons or could this be an exaggeration (like a cup of oil on the floor looks like a gallon)? I ask because, I do not think you could get 2 gallons from an intake gasket leak.

If it was 2 gallons, I would suspect that when the gasket failed, it hydro-locked the engine and a cylinder wall was broken, letting the block drain into the pan. I think I would try filling the block, while the intake is off, and see if water pours into the oil pan.

I truly hope this is not the case. Good luck.

I'm less than 2 hours from you. If you decide that you don't want to tackle it on your own, give me a holler.

"you just left the garage", was there time enough for 2 gal of water leaking into the sump, considering the coolant system was under pressure? I seriously hope your liners are fine. I know the feeling...
