300sd engine swap...parts replacement recommendations?

I am changing the engine in my 82 300sd (due to low compression on one of
the cylinders/poor starting in ontario winters). I want to be sure I do
everything that should be done while the engine is out of the car.
I have ordered the front main seal and a bunch of other stuff.........but
I see no mention or guides available for the rear main seal. I'm not sure
if the engine being transplanted should have a new rear main seal, or if it is an easy job....... or not.

Anyone with any experience or info on this?

84 300SD OIL HOSES/LINES

Are the couple of hoses at drivers side of what I think is an oil cooler are those the oil lines? These hoses are like a hydraulic line, alterante between rubber and preformed special metal fittings and shaped metal lines. They appear to be a pre determined length and appear to go back near the trans. If so are they easily replaced? Cost and availability of the lines and do you have a how to guide? I recently used your ignition switch guide and replacement parts. Thank you it was quite helpful. One other question is the oil pan and gasket available through you?

1984 300sd engine keeps running.

My 1984 300sd will keep running after the key is out of the ignition. I do have a new shutoff valve to replace, but have not gotten to it.

Well, I figured out why the engine cuts off some times before I get the hood up. When I'm getting out of the vehicle I tapped the brake and it killed the engine. I do this with regularity now. Has anybody heard of this? And if so, is it still my "shutoff valve" or a vacuuum booster to the brakes?

84 300SD trouble starting

having trouble starting. This is my first (not last) mercedes. Its an 84 300SD. Hot or cold does not seem to matter. When you've waited for the glow plug light to disengage and try to start it either will or won't. Some times it starts right up others you can wait up to ten minutes. The battery appears to be fully charged. I can hear the starter gear engage. I'm leaning towards the ignition. I don't know if this is a common or easily fixed situation? The car has 267,000 miles shes just getting broke in:). I appreciate anyones suggestions. thanks benzbear68
