Mechanical sound

[henry sweden]

Hello Mark II Friends!
I have a mechanical sound in my 56 markII..
I think its from the lifters...but im not shure.
When the engine is cold,there is nothing.But after some minutes when the engine starts to get warm...you can her it coming...knock knock..but only when its Idle...Nothing over 1000RPM.
I have 20w-50 mineral in it now...and i only drive it on warm summerdays..(not so often here in cold Sweden)
"Thats nothing to be worried about"...have i heard.But i dont like it.

Any Tip to solve this "problem" from some one her??

When it warms up and starts the noise, disconnect the belts to see if it's an accessory or the engine itself.

Welcome to the site.

I hear that there's a Mark II convertible in Sweden owned by someone named Bo. Know Bo?

Thank you!
That is a good tip to eliminate an accessory.I will try that...
But i have a feeling the noise coming from "inside"...more from the left side off the engine...i dont know...hmm..

No, i have not heard about Bo.I think we have maby 5-10 markII in sweden.
Only 1 was sold new here(what i heard).And that Car was sold to Norway for 3000 dollars in 1970s...a black one.

It's only two acorn nuts to take off a valve cover. But first, take a 1-meter piece of conduit or tubing and hold it cupped to your ear. Wait for the noise to start and isolate it to either valve train. The tubing will amplify the noise without you doing a face-off with your engine. If you can't isolate it to either side, you could be hearing a cam or bearing problem.

Is there metal in your oil? Do you use an oil that has high ZDDP? Our old flat-tappet engines require extra lubrication at the cam lobes, or they can disappear.

If it's a bearing noise you can use a higher viscosity oil, but that only delays the inevitible.
