S54 Oil Accumulator

I'm finally taking over the maintenance of my M Roadster from my dealer and doing my first oil change. Now that I have it up on the lift, I see that it has an oil leak. I remove the under tray, and can see a drip coming from the lowest point of the line that connects the VANOS accumulator to the head. The line is being held together by a screw clamp, is this right? When I look at RealOEM, the parts diagram shows a line with crimped fittings. Would a dealer mechanic to save time just cut the line and put it back together with a screw clamp? That doesn't seem like a secure way to seal against 1700 or so psi.

Has anyone seen the replacement part and can verify whether it a also uses a screw clamp?

Thanks,

John

Surprisingly, it is a screw clamp. Try tightening it.

I had the same problem with my car. The hose clamp only holds the silver insulation on the line (not any pressure) You have to replace the line, it's a SS flex hose under the insulation thats leaking not a big deal to replace about $80.00 .

Your best bet is to go with Ron. He helped me a lot when I did mine he gave me torque specs and what I needed to do the job, Thanks again Ron.

Great! I've sent you an e-mail.

I did look at the RealOEM pic, and it doesn't show the outer cover and screw clamp. I'm glad to know the screw clamp just holds on the outer silver cover!

John

Thanks, Ron!

I just want to publicly thank Ron for his outstanding service! The line is here already, long before I cleaned the car well enough to install it.

That thing must have been leaking since new; there were places where the oil sludge had built up to almost a quarter inch. Even with a lift and bottle brushes, it's no picnic, but after a quart of Simple Green I'm almost done from the bottom; then I'll drop it and work down from the top, then lift it and re-clean the bottom...

I knew there was gonna be trouble when I removed the lower cover and a P/S cap fell out...

Thanks again, Ron!
