Cam shaft oiler & fuel line issues
79 Euro 450SL - I've had it 5 months.
A 1000 miles after ownership the right side of engine started making a ticking sound similar to a starved valve lifter, you could here the noise was in the right front by the timing chain with a stethascope.. Wife took the car to a local repair shop that specilizes in MB, they said it was most likely the timing chain est cost of repair 1,500 or could be worse 4,500?? They changed the oil to a lower weight to see if it would help, no change. The car was driven another 300 miles.
I decided to look into doing the work myself, as the car has to many issues for me just to write checks. I pulled off the right side valve cover; found 3 immediate concerns;
1) The right (front were the noise was coming from) was missing the plastic clip holding the oiler rod, the oiler rod move out of the left rear clip. No evidence of the missing clip, oil and filters have been changed twice since start of problem.
2) In looking at the cam rollers, there was no obvious damage to my untrained eye, however, the cam roller on the #2 exhaust valve has a bronze colred 1/4 inch line where it rides on the valve, does not appear to be any marring or scoring all others nicly polished.
3) In looking at the oil holes in the cam towers, all were drained, with the exception of the front tower that had the missing end clip, it was full of oil.
4) In pulling the vlave cover off, I discoverd the #3 fuel line weeping at the injector, checked the fitting, it was snug.
Anyones guess if the ticking will go away with the oil clips replaced, or are we in for more damage? Why was oil in the front tower and not the others?
How do you stop the weeping fuel line, if I have to replace can I buy a single line?
