Putting new ignition and column lock in my 1984 300SD.

Lots of problems.

1. Kept the 2 vacuum hoses on the housing, but the tubing came out of them.
Which one goes where? I think one tube has a stripe.

2. These tubes have oil ( in the switch too ). How to fix that?

3. Can't remove the plastic piece ( for key buzzer ) off the old housing.
How do you remove it?

I hope after all this, the starter, heat & ac, and blower work.

Thanks.

The vacuum line with the blue stripe is the one closest to the switch. The oil indicates that the vacuum shutoff (on the IP) is bad - diaphragm split. Easy to replace and you can get one at the junkyard very cheap (test with a vacuum pump to see if it holds). If you don't already have a vacuum pump it will pay for itself on this job alone.

Just the second what CFH said.

The hoses on the housing can only go two ways. If you reinstall them and the car doesn't shut off with the key, then you have them backwards.

The tubes have oil in them because your vacuum shutoff valve has failed. Get it fixed because its shooting oil other places too.

This one is hit or miss. Some times when I've replaced these the key buzzer switch it comes right off. Other times I've broken them and replaced them with a new one or simply left it off. Put the lock in a vice grip. Get tiny nails and stick it in both sides of the switch and slowly and gently pound the nails on both sides releasing the little pressure clips on both sides to get the buzzer to slide out. Again, it might not come out for anything. You can just buy a new one or go without it.

Thanks for the help, but....

I don't what a vacuum shutoff valve looks like. Found a Diesel Shut-Off Valve for sale.

Same thing? Where is it located?

The Vacuum Shutoff Valve is located on the Fuel Injection Pump.
Pelican Parts lists it as "Diesel Shutoff Valve"
