85 300TD Alternate Hood Release Fix

I Just Broke my Hood release cable. After I open the hood, can I cut the cable about three feet from the hood end, and reroute the shortened hood latch end over the left headlight? There I could make a loop in the end and kinda hide it on top of the light? I think I can remove the outer sheath and just use the wire to unlock the hood. Please comment on the feasability/drawbacks ..... thanks

1984 300D oil under rear end

Hi all, my 1984 with 179,000 miles clocked had a litte wet spot under her rear-end today after we went for a cruise. I got underneath her and there was evidence of oil being slung around on the underbody. It was concentrated on the passenger side of the differential but hard to pinpoint. It didn't look like either of rubber boots were cracked so I am leaning towards the axle seal on the differential. Does it sound like I am going in the right direction? Looks like one of those cheap-part-lotta-labor type jobs. Thanks, Mike

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.
