diesel won't start 1978 300cd

I'm a diesel novice, but have had lots of old gasoline fueled cars, from 1930's - 1960's. Have had my 300cd for about a year and driven about 7,000 miles. Adjusted 300cd's valves last week (all were a little tight, but ok and was last done about 9,000 miles ago according to records). Replaced glow plugs last year. Had in-tank fuel screen cleaned last year. Now about 1/2 way through a tank of fuel that's about a week old. Started this winter even at 20 degree temp all day. Car now in heated garage. Has been starting and running ok. Driven several times previous day without a glitch.

1978 300SD Oil Leaks

I've been running through a lot of oil lately so I had my engine cleaned thoroughly and ran it at idle for 30 mins. I noticed that oil was leaking from the grate at the bottom of the transmission, but nowhere else immediately noticeable. I suspect that this is the dreaded rear crank leak that requires engine removal, but would appreciate confirmation before I go out and solicit estimates. Am I correct?

overheating on my 1980 300 sd

I have replaced the thermostat,aux water pump, water pump, all hoses,had the radiator rodded out by a radiator repair shop, blower motor replaced and I am still just short of 100 degrees on the cars gauge backed up by an infrared gun. I have checked and my major problem was the radiator as the bottom was cold and the top was running hot. After all this I now have hot all over readings. The thermostat was an 80 degree one and was put in the right way. I am getting heat thru the a/c so I assume there are no bubbles in the system. The top of the radiator reads 100 degrees with thr IR gun.

78 300SD Turbo Connector Hose

Is there a particular type of hose that must be used for the Turbo Connector Hose?

My turbo had a braided hose, similar to that of the fuel line return hoses but larger, that was leaking pretty badly at both ends. I removed it and took it into my local parts store and the guy at the counter said that I needed that particular style hose. He cut me a length of 3/8" fuel hose to hold me over until I could get my hands on some.

1982 300TD Weird compression test results

Checked compression with engine cold one year ago. For this test I started at the front and went straight down the line to the back. Results were 370 - 370 - 370 - 290 - 330. Today I tested the engine warmed up and instead of going down the line I tested each cylinder in firing order. For this test the results were 310 - 310 - 310 - 220- 310.
