What did you do to / for your E53 today??
 

Put the valve cover on with no gasket and put in the front two bolts with two washers each (to compensate for no gasket). Tighten the two front valve cover bolts while the timing chain cover bolts are a little loose to push the cover down right into the bottom seal then tighten the chain cover bolts before removing the valve cover. Works every time for me

Replaced all four O2 sensors. Not as bad a job as I expected after reading everyone's experiences here. Hit them with PB Blaster the night before. They all loosened easily. Biggest PITA was feeding the wires for the lowers. Ended up having to remove the cabin air intake, but other than that, a piece of cake. Still had time left in the day to wash and wax her.

Dyed my faded lower and door trim back to gloss black. Let’s see how long it lasts. If it’s once a year I’m happy.

Drivers window regulator and door handle carrier while I was in there. Window still going up slowly so trying to figure that out.

What did you use?

Needs lubrication. See:

Slow window, fixed with dry lubrication

25% faster going down 60% faster going up after just dry lubrication spray

Some Forever Black bumper and trim reconditioner. Amazon for like $18? Or so. Two coats. Brush strokes are visible with the foam applicator. Not bad though. I’ll use something else next time. Maybe an old shirt. Taped off painted areas and just took some time. 2-3 hours total

Cool. Yeah, I've got some.
I found something that lasted longer, but I can't remember what it is. Would have to go heck in the garage.

I just installed a top timing chain cover yesterday: I was able to simply push it down onto the lower seal by using the open jaw of a longnose pliers* levered from the T-55 bolt in each of the camshafts. I tightened all the bolts just until the back seal was touching then I levered the intake side down and tightened the middle bolt "snug" but not torqued. I did the exhaust side similarly then i torqued down all the bolts evenly by doing them each just a little at a time.

* Rough side of jaw inside the T-55 and smooth outer side down against the seal surface. You could use a piece of plastic or wood shim to protect the valve cover seal surface.

PS. Don't forget to put RTV in the bottom corners of the upper timing covers.
