I recently purchased an 83 240D with a window in its engine block. I pulled it and found that the #1 connecting rod had broken loose at the wrist pin and destroyed the block.
I have another 240 motor out of a 1978. We started it on the floor of the shop last week and it runs great, but i am hesitant to put it in to the newer car for a couple reasons.
1. The old motor has loop glow plugs. I am hoping I can simply replace them with the newer style pencil plugs and hook my existing factor fast glow relay to them. Are there issues with that idea?
2. I have read that there were horsepower upgrades that accompanied the addition of the egr and the head that accepts the smaller pencil glowplugs. This 240 body and interior are really nice, so I would hate to "depower" it with an older motor. They don't have many horsepower to spare.


I may be able to score a later model engine from a friend, but honestly the 1978 I have seems to be really low miles. It has almost no blowby and the camshaft lobes look like they just came off the assembly line.


I am not sure which route to go.
