unimogjohn Posted March 19, 2011 Share Posted March 19, 2011 Tom, same problem as mine. Condensation in the cylinders have rusted the rings to the bore. Probably one or two cylinders. Just a lead pencil line so it is not extensive, but enough to freeze it up. Took me six months to free up mine and I tried all kinds of stuff. What finally did it? Kroil. Others have use acetone and auto transmission fluid, a 50/50 mix. Keep squirting it in the cylinders and then put pressure on the crank. Or you can put in high gear and pull it with your car. Make sure that it is on soft surface first, like gravel, to see if that minimum force will work. If not you can try pavement. Good luck.

unimogjohn Posted March 20, 2011 Share Posted March 20, 2011 Tom, forgot, also put the car in gear, get a couple of folks and rock the car back and forth in the garage, make sure you you have oil/penetrating type in all the cylinders. If the rust is not bad, this should break the rust bond. Hope this help, good luck. John Link to comment Share on other sites More sharing options...

jbbuick22 Posted March 21, 2011 Share Posted March 21, 2011 Tom, It would be better to remove the lower flywheel housing and turn the engine over from the flywheel. First try to move it both ways cw and ccw, if it only moves a little check to see if the waterpump shaft is moving also, if not the front shaft bush could be the problem. Towing the car is not a good idea, you can cause a lot of damage. Ask Tom Black about towing!!! JB22-6-55 Sport Touring Link to comment Share on other sites More sharing options...

Mark Shaw Posted March 21, 2011 Share Posted March 21, 2011 Do your wheels turn when in neutral? If they are locked up , rocking the car will do nothing to break loose the engine... Link to comment Share on other sites More sharing options...
Guest tom pre Posted March 21, 2011 Share Posted March 21, 2011 hi mark. good question. in neutral wheels turn freely. im a little hesitant to tow her untill ive done everything else. i can drag her anyplace, but will i do damage ? im soaking pistons & just ordered some kroil. any ideas ?

Mark Shaw Posted March 22, 2011 Share Posted March 22, 2011 You want everything to be lubricated... Drop the pan and lube the rods and mains. Also check for stuck push rods & valves. Remove the rocker assy. and tap on each valve. If the spring returns them, they are OK. Leave the rocker assy. off the engine until it turns....Check to be sure the starter gear is retracted before you rock it or drag it.... And, don't pop the clutch in first gear... Try second & allow some slip so you don't damage the crank.My 2 cents... Link to comment Share on other sites More sharing options...
JerryVan Posted March 22, 2011 Share Posted March 22, 2011 Don't get impatient. Let it soak for a week or two. All the worst things that happen to engines in cases like this are due to getting too eager. Link to comment Share on other sites More sharing options...
JerryVan Posted March 22, 2011 Share Posted March 22, 2011 Any chance your head gasket leaked coolant into any of the cylinders? It wouldn't take much. Link to comment Share on other sites More sharing options...
Guest tom pre Posted March 22, 2011 Share Posted March 22, 2011 hi jerry. i'll stay patient. cant answer the leaked coolant question. yet/ Link to comment Share on other sites More sharing options...
unimogjohn Posted March 23, 2011 Share Posted March 23, 2011 Tom, I would drop the pan and caps AS A LAST RESORT. The caps have shims and they will all drop out when you release the caps. It is then a real effort to to get everything shimmed correctly. Be patient and use Kroil. Just keep trying. It took me almost a winter to get mine broken loose.

tblack Posted March 24, 2011 Share Posted March 24, 2011 These things can be frustrating...my 21 model 44 was tight after a rebuild that occurred 20 years prior(but never run) ...I was not turning over with starter generator real fast and you could feel it labor at a specific point....I towed it and found the problem....the cam gear(fiber) was damaged and towing did it in.A year later the car seized running down the highway...this time it was the bushing coming out of the engine casing it seized to the pump shaft....no other damage and it runs fine today. I can't imagine that this could be your problem but I would see if the water pump shaft has a bit of movement allowed by the tolerance in the gear meshing.Your problem is concerning as you ran less than a year ago parked it and it's stuck...I would soak for 1 month then rock the car again...I'd be suspicious that you have gotten water in a cylinder from a head gasket or cracked head I can't imagine that condensation/rust is locking you this hard in this short of a period of time....If you break loose be looking for the potential of a bigger problem. Anything to note when you ran it 10 months ago???Good luck Link to comment Share on other sites More sharing options...
Dandy Dave Posted March 25, 2011 Share Posted March 25, 2011 Jack up one rear wheel and then rock the wheel back and forth with the trans in high. Rocking the wheel will send vibrations though the crank in both directions without a lot of brut force which is what you want. Check the stuff previously mentioned first. Dandy Dave!

unimogjohn Posted April 8, 2011 Share Posted April 8, 2011 Tom, any progress? Or anything to report? We have not forgotten you. Link to comment Share on other sites More sharing options...
Fred Rawling Posted April 24, 2011 Share Posted April 24, 2011 You stated that you could not turn the engine over with the hand crank. Does it turn over with the starter?On my 1928 with a rebuilt engine, I could not turn the engine by hand to save my sole but the starter turned it.Is this a new rebuilt engine or an older one?

50jetback Posted April 24, 2011 Share Posted April 24, 2011 Tom,If you already have the starter motor out try using a large screwdriver to lever the flywheel around. You can do this by engaging the scredriver blade into the ring gear teeth and pushing down using the hole in the bellhousing for the starter motor as the fulcrum. The only word of caution is to watch out for your knuckles. Link to comment Share on other sites More sharing options...
Buick Downunder Posted April 29, 2011 Share Posted April 29, 2011 Hi Tom - I am worried that suggestions to tow start a car of this age :confused: Firstly, if it is stuck rings, you will simply crack any that are stuck and then have the joy of pulling it all down for a hone and re-ring Also, not knowing for sure the problem, the risk of damage to crank, bore, pistons, rods, rings, valve gear, gearbox, rear axle (shall I go on!?) is far too great a risk to base on such a decision. It sounds like you are on to this anyway. If you can't turn the engine from rocking it in gear, then you still have issues to resolve. Secondly - Can I suggest that the water pump / shaft is definitely another place to look as others have stated? If it is a stuck pump, there is no way in hell you could turn the motor over. Good luck and keep up the krol! Link to comment Share on other sites More sharing options...
