Hood does not unlatch when Release Lever is pulled

The hood on my 560SL does not pop loose when I pull the Hood Release Lever.
Have to have wifey apply upward pressure on hood as I Pull lever to get it loose.

Comparing my 380SL which works fine with the 560SL, I noticed that the rubber pieces
around the Hood Springs are missing on the 560SL. Are these what cause the
Hood to pop loose?

I think those are to prevent the springs from hotching up the paint next to them if they vibrate when the hood is closed.

Usually, the hood not popping open is adjustment of the latch or the little rubber covered bumbers at teh front corners of the hood. Maybe the rubber has gone from age?

Just a wild guess,
Scott

There's a pin in front of the hood latch. Give it some oil. The pin sits on a spring inside a sheet-metal-thick cylinder which can bend (under the radiator support) and cause friction allowing the pin to get stuck in the down position, not constantly applying upward pressure on the hood. I have noticed the problem if you press down hard on the hood after it has latched, moving that pin a little deeper in the cylinder than normal where it gets stuck.

Also, the release cable stretches over time. There is an adjustment nut where the cable sheath connects to the latch assembly under the hood. If your cable is indeed stretched, you might have a few turns left on this nut to compensate for it.

Fonzi, thanks. Mystery solved.

My red 560SL does not have that pin. The PO must have removed it.
Below are photos of my ivory 380SL with the pin, and my red 560SL with that pin missing.
Can just the pin be ordered?????

I think the whole assembly comes together. You can get one from any salvage 107 probably.

Doesn't look like it...part number is 1158800160 for the entire piece. Start hitting the salvage yards or maybe someone here can supply one. I was shocked at the price of a new one. Actually hope I made a mistake looking it up but I don't think so.

$700 MSRP

Ouch. I bet I could make one out of a screw and a spring before I would pay that price.

Thanks

Big time ouch! I did a search on EPC and it looks like the part was used on many different models...

100,107,108,109,110,111,113,114,115,116,123

Wouldn't think it would be too hard to find one at a salvage yard or someone parting out a car.
