First look at b1d not good news

[oldmopar]

I went out today to check out the 49 b1d I towed home last weekend. Went to drain the oil nothing came out had to dig through about a inch of sludge. tried to crank the engine and it is stuck. I was hoping the truck would at least turn over maybe start. I would appreciate any suggestions for a stuck engine. I have removed the plugs and distributer (in case it was stuck) and put about a quart of wd40 down the plug holes. I did have a socket with a breaker bar on the crank so I did use reasonable force. The rest of the truck is not that bad a few frame brace will need to be reinforced and the trans and rear is still unknown. The truck is outside right it was planned to be a parts truck for my wd21 but It is not bad enough to be a parts truck with 2 or 3 years work and $10,000.00 and it should be ready for the road:).

Did the WD-40 leak down past the rings?

My suggestion is to go to the NAPA store and buy one of the "hold open" devises used to keep valves from dropping down into the cylinders when removing valve springs. Screw that into a cylinder full of WD-40,ATF,Brake fluid,or whatever,and put 125 psi of air pressure behind it. Take the oil filler cap off,and sit next to it until you hear "blub,blub,blub" coming out of the base pan,then fill that cylinder with a thin lubricant like Marvel Mystery Oil,ATF,or WD-40,and pressurize the next cylinder. Repeat until you have them all done.

In a worse case scenario you might have to remove the head and the side cover to get the valves to close so you can pressurize it properly,but it's worth the work if by doing this you can avoid having to break pistons or scour cylinder walls with broken rings by unsticking one "dry". If you have a valve that just won't close,lube it up good with lithium grease and then tap it closed with a plastic hammer after making sure it's not on the high spot of the cam lobe.

This is easier to do on a OHV engine because all you have to do with one of those is take the valve covers off and unbolt the rocker arms to get the valves to close.

The advantage to doing all this work is that once you have it unstuck this way you can get it running to see if it knocks or smokes,and even more important,you can run it enough for it to get hot so you can tell if the block ins cracked.

For all the trouble it is, I would pull the head. That will tell you almost everything you need to know.

My engine had a broken valve (and a mouse nest in the oil pan).

Have been thinking about the sludge and good point about possible bent valve or other damage also noticed the oil filter was missing and the lines were crimped off so I think the best choice is to check this out a little better or maybe just pull the engine it has 76,000 on the odometer. I have a wd21 that I will be starting on soon and have a 230 engine from a 60 power wagon that will be going in it. It has a 230 out of a 50 car maybe a Dodge it was cranking but bad compression in one or 2 cylinders could be a stuck valve. So this will have to wait its turn.
