OM617 questions
« on: 10 May 2020, 04:35 PM »
Did a little bit of work on my 1980 W116 300SD this weekend.
Deleted EGR and temporarily ran alternative intake until I decide if I want to buy another T-bracket.

When I replaced fuel filters, I ended up with a leak at filter housing. Even with new washer.
I want to update to the later filter housing anyway, so now is a good time.
Does anyone have a good one they would like to sell?

Bought a new cigar hose, turned out to be too short. I guess there's a long and short version. Ran regular fuel hose temporarily.

Also noticed I have oil leaking up through a valve cover stud. I replaced the gasket when I did valve adjustment a couple weeks ago. Is there supposed to be any type of seal or washer under those nuts?

I'm missing a hood latch striker/buffer. If anyone has a good one laying around I'll take it.

I have 3 of the later "02" fuel filter heads and I include the 2 o-rings (in brown FMK) that hold up to biodiesel.
Send me a PM.

The sealing surfaces of the fuel filter heads have been hand lapped.
These fuel filter heads are from the last 3 of the 5 CAT 1R-705 Fuel Filter Upgrade Kits.

It looks like the area around the hole for the hood strike is deformed. You need to work this metal back out. If this is still bent you will probably break any new deflector.

These are available new from MB again.  There was also an ebay seller in turkey offering them for @1/2 of MB.

Yes, it looks like it's been slammed on a few times.  I pull the latches back when I lower the hood until it passes the strikes.
I should be getting one from Alec soon.

The fuel filter bolt needs to be cranked on, keep at it until the fuel stops. New aluminum washer would be best as the copper washer are usually too thick and take even more force to seat properly.

Use a propane torch on that metal to soften it up, and reshape the metal as best you can with a metal hammer and a punch, it doesn't look too bad and definitely fixable.
