1977 300D coolant leak

Last year my parents bought me a 1977 240d with a 300d engine. I love the car because of its old style and drove it for about 4 months before pools of coolant started to appear under my car. I am wanting to fix my car now that my dad recently passed away and i need to know if anyone could help me by finding out what the cause is. I have had people tell me its a freeze plug behind the engine. All can tell is that its leaking between the engine and transmission. if anyone could answer this for me i would appreciate it and i would know that i must purchase a freeze plug.

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?

617 Diesel Injector Lapping Procedure

As I continue my quest for perfect 617 Diesel Injectors & truth I have just learned today that I need to have the internal surfaces of my injectors lapped to remove grime & build-up. . .

Is this something I can do myself (lapping the surfaces) if I take on the task of re-building my 617 injectors w/new Monark nozzles?

How would I do this?

thank you & Happy New Year,

1980 240DD Transmission Rough at Start

I have a 1980 240D sedan with an automatic transmission. When I start the car and drive it first thing in the morning, the transmission shift from first to second gear is rough, it snaps my head when it shifts! However, once I have been driving it for about 15- 20 minutes and it's warmed up, the shifting from first to second is much smoother and about the same for the other gears. Is my transmission having a problem, or is this typical for a car of this age?

1981 300SD Low compression #1 cylinder

I finally got around to checking my compression and found (the car has 300K+ miles on it) all cylinders had 280-325 on the compression EXCEPT #1 which I checked 6 times with different crush washers and could never get over 160.

I'm thinking I need to recheck my valve clearances one more time. What else can I look for to try and figure the problem?
