Dwight Romberger Posted July 23, 2012 Share Posted July 23, 2012 (edited) Hi all,I had my 1930 model 47 engine professionally rebuilt 1 1/2 years ago (cylinders bored, new everything from EGGE, et. al.).I have been turning it over with the crank regularly (at least once a month). Today when I hooked the battery up to use the starter it would not turn over. I tried the crank and I can't turn it over with the crank. It is offically stuck.So, I pulled out the plugs and shot oil and PB Blaster into the cylinders and I am letting it sit over night.I there anything else I can try?Thanks in advance,DwightCan I try to turn it backwards or would that do damage?

unimogjohn Posted July 23, 2012 Share Posted July 23, 2012 Dwight, You are doing things right for now. I would continue to spray your favorite concoction for a couple of days and then try to turn by hand. If that does not work, I would put it in second gear and then with a couple of friends rock the car forward and back a few times. If it is barely stuck, this should free it up. If that does not work I would put in a new concoction of 1/2 ATF and 1/2 acetone. That is the recommend fluid to break the little rust bond between the rings and the cylinder wall. It does not take much rust to stop it from turning. Keep us updated. Link to comment Share on other sites More sharing options...
50jetback Posted July 23, 2012 Share Posted July 23, 2012 Try removing the starter motor and use a large screwdriver on the ring gear teeth ( use the starter motor hole as the fulcrum ) just to asses how stuck it is. You may find a little extra force will break it free. Link to comment Share on other sites More sharing options...
Dwight Romberger Posted July 23, 2012 Author Share Posted July 23, 2012 Thanks John and Stuart.Good News!I gave it a try with the starter today and it turned over!Now what?Based on some of the other threads, I should put oil in all the cylinders (1/2 cup?), turn it over for a couple of minutes, then drain the oil and put fresh in the crankcase.Does that sound right?Dwight Link to comment Share on other sites More sharing options...
FLYER15015 Posted July 23, 2012 Share Posted July 23, 2012 Dwight,I would certainly not put a half a cup of anything in the cylinders. There is a chance the engine will "hydro lock". If your goal is to lube the cylinder walls prior to full oil pressure, a few sprits of ATF will do the job. Fresh "break in" oil is also a good idea, and I would contact EGGE for sugguestions, but it is usually thinner than you would normally run.Just my $ .02Mike in Colorado Link to comment Share on other sites More sharing options...
unimogjohn Posted July 23, 2012 Share Posted July 23, 2012 I agree with Mike. Also did you have the plugs loose or out when you left it sitting? Condensation is usually the bad guy in this. I would just put in a teaspoon of Marvel Mystery Oil and put the plugs in and turn her over a few times. I would not over do it either. Just go back two your every couple of months routine rotation. Also you have to remember you are not building any pressure so your main bearings are not getting much oil if any. You want to be careful. Link to comment Share on other sites More sharing options...
Dwight Romberger Posted July 23, 2012 Author Share Posted July 23, 2012 OK Mike and John. ThanksI had the spark plugs in while it was sitting. Oil in the crankcase but the radiator is not hooked up yet so no water in the jacket or gas in the carb.I will pick up some Marvel Mystery oil tomorrow.I will also change the oil to get the PB Blaster out of there.Thanks again for all your help.Dwight Link to comment Share on other sites More sharing options...
