1988 318 not cranking over

Hello all

I know this is not a hot rod ,but I have always gotten good answers here.My father in law van has a 1988 dodge van with a 318 in it .He thought he had a bad battery or starter. I replaced both and the motor still wont crank over .The starter is kicking in and the battery has a full charge. We got the starter to work on the bench and I rechaged the battery so I believe they are both ok.
I turned the motor over by hand ,and by the way was VERY hard to do . After I did the motor cranked over slow at first ,then started. It smoke like hell for about 5 minutes. We ran it for about half hour ,shut it off and it restarted.
Then the next morning it was doing the same thing it was.
My question is ,,is the some internal parts of the motor that would "lock" up the motor? If I turn it over by hand it will crank slowly then start .
Any help would be great

Jeff

My guess is you're leaking enough coolant (or oil I guess) into 1 or more cylinders to raise the static pressure high enough to prevent the starter from turning the motor. Once you turn it over by hand a couple of times, you clear enough of it to start it. The rest burns off and it's good until it sits and leaks more into the cylinder.

If it still won't turn over with the plugs out I'd be checking the connections on the starter/battery. This is a strange problem.

318 not turning over

C
Put on a new battery and starter ,,cleaned all the connections . Would a bad bearing or something internal of the motor cause this problem?

A spun bearing can prevent the engine from turning over

Yeah, but OP says when he got it turning by hand, the starter turned it and it started and ran after burning off whatever it is. Wouldn't do that with a spun bearing.

Have you had the battery on a load tester? They will show fully charged then crap out under load if it has a bad cell. Most all parts stores will load test for free and if you do need a new one the core is right there
