300D persistant knocking noise

I am still trying to track down a baffling noise that one tech has said is a rod knock. The 300D has 117k miles and has had regular service by the M-B dealer where it was purchased. I am the second owner having purchased the car at 116k.

I have now driven the car 1,500 miles half of it on Interstates. Last weekend I did about five miles at 95mph. The noise hasn't changed the oil pressure still pegs above 3 bar at speed and just below 2 at idle.

I keep thinking that if this was a rod bearing it would have gotten much worse by now.

1982 617 balancer install

Kent,
I am replacing the front seal in a 1982 300d. I used the kit and the seal installed quite easily. The problem occurs with the install of the balancer. The two pins are not attached to the balancer on the 300D as it was in my 240D balancer. The problem is that even when I heat up the balancer to 300 degrees in a toaster oven, (it can be positioned for nearly a minute) the pins do not fit into the holes. Every time I try to insert them, they go in partially and then stop with most of the pin sticking out or on a angle.

83 300D Windshield Washer Kit/Spray Pattern

I installed the Windshield Washer Squirter kit recently. The installation went well, once I figure out how to remove the old squirter nozzles. I now have the situation where the nozzles spray most of the washer fluid over the roof of the car. The driver's side nozzle, in particular, misses most of the left half of the windshield. Is there a way to adjust the spray pattern on these new nozzles?
