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.
