any tips for oil filter housing gasket? (84 300SD)
84SD I'm working on my oil filter housing gasket. The 2 bolts on the left are out. I have the center and bottom bolts to go.
It looks like the engine will have to be raised to get the center bolt. I'll be lifting with a floor jack. What is the least amount of stuff that has to come off. Are there any "while-I'm-at-its"? Oil was dripping off the bottom of the housing and pressure sending unit. Hopefully, it is only the gasket. Comments? It's lunch/break time for a little while.

On a W123 a Member said the Mechanic removed the Steering Box. And, that makes sense if you want room to use a Torque Wrench on the Bolts.
I found I could squeeze a Beam Type Torque Wrench in to get at all but 2 Bolts. I replaced the Allen Bolts in those 2 spots with regular Bolts and was ablie to use a short Socket with the Beam type Torque Wrench. But, that is on a W123. While the Housing was off I also changed the Gasket that goes on the Rear Plate. That is the Plate the Turbo Oil Line Bolts to and the Oil Pressure Sending Unit Bolts to. Check that Plate for Hair Lline cracks radiating from the Threaded Holes.

This is how a 126 comes apart
Before starting:
Wash that pig off. There is oil caked on the back of the engine that has been neglected - even if the rest of the engine is acceptable. Blast it at the car wash. I didn't but will next time. Take a 6mm allen head wrench (not a socket) and cut the short leg and make it shorter. From above: 1. Open the oil filter housing so it will drain. From underneath: 1.Pull the electrical connector on the oil pressure sending unit. 2. Pull the oil line banjo bolt to the turbo 3. Pull the center bolt that holds the engine to the motor mount. (mine was missing. I'm hoping the parts car has one. 4. Remove the lower 2 bolts that hold the housing on. I had to leave the back one in the housing. The front came out with a short 6mm allen socket on a 1/4" drive ratchet. From Above: 1 Disconnect the clip that connects the fuel pedal linkage to the engine and disconnect the linkage. 2. Disconnect the vacuum lines to the VCV and move them out of the way. 3. Pull the upper left bolt using whatever 6mm allen socket you need. 4. Jack the engine up using a block of wood on the oil pan per the FSM. 5 Remove the center bolt. This should be the last one and the housing is free. Clean, remove the old gasket. Per 911 Clean the plate & get ready to replace that gasket also. I'll go buy 2 regular bolts perhaps more because the allen heads were a pita. The mosquitoes are out and I'll quit for now. Hopefully reassembly tomorrow afternoon.

When reassembling, ensure that there is a copper washer on both sides of the banjo fitting and bolt assembly for the turbo oil line. Unknown to me, at first, the inner one fell off when re-bolting the oil line to the oil filter housing. If you miss it, you will leave a large puddle of oil in no time. (Don't ask me how I know.)
(Also, removing the steering box gives you so much more room to work. Pop the tie rods off and leave the pitman arm in place. Also, disconnect the upper "square" end of the flex steering link and not the splined end. This will save you considerable frustration trying to get things centered again.)

DO NOT USE SILICONE GASKET! (ok maybe a VERY VERY thin amount)

Just get the MB waffle gasket and install it dry onto clean surfaces

I was hoping to leave the steering box alone but perhaps not.

I installed it with the engine out, so maybe that's the difficult part.

MB design is probably best, but I have had no problems with the Victor Reinz version on 6 installs... And I install them dry with no sealant. Of course I say this now, and then I'll have an issue.

I DIY'd this job on my W123 and it just plain seemed like I didn't have enough hands to steady everything and get it together smoothly. I also used a flat gasket. It ended up leaking worse than before when I got it all back together. I then gave up and took it to my indy. I know they used the MB waffle gasket, but I don't know what else they did differently, but it didn't leak when they were done with it.

If you don't care about torqing it down then there is room. I did the whole job without removing the Steering Box but it never occurred to Me to do that. I have never seen what it looks like under an SD so I cannot comment on the room on one.

I guess I get to play the Bad Guy again. I coated one side of the Waffle type (from the Dealer) Block to Oil Filter Housing Gasket with Copper Kote or Gasgchinch (can't remember which both are a type of Rubber Cement but the Copper Kote has Copper Particles in it) and suck it to the Oil Filter Housing.
That helped Me have enough hands to do the job. Nothing like having a loose Gasket shifting around while you are trying to hold on to a somewhat heave awkward Part in a tight spot.
