107 450SL cam valve ticking NOT GOOD? Worth fixing or dump car?
 

Here is the pic of the cam. Looks a little beat up for sure with scoring.

I bought this whip to resell and question is do I fix it car or just part it out? I did get the car cheap so take that into consideration.

Would I have to replace the cam or could I just replace the whole spring assemble on that one valve? I don't need it PERFECT to sell just need it running decent. I am not making a concourse car here just a cheap car for someone to have fun in!

The plug was perfect so no internal issues going on.

Any all advice appreciated since right now I am moving toward parting out the car since the tick is loud and I got a good deal since I told the seller engine was shot :)

Thanks,

Brent

Is the Oiler tube streaming oil on it while it runs?

I think some cardboard to catch the splashing oil might enable you to run the car with the valve cover off. I’ve never done it myself though.

Good idea
 

sure I can run the car and see what happens....

Park car outside and see what sprays out!

Thanks!

If you have a flat cam lobe, you'll never get rid of the tick unless you replace the camshaft and rocker. I don't think that the cams are that much and the job on the older V8s is a cake walk.

cam, rocker, possibly lifter-doubt it-, oil tube and valve cover gasket. hardest part is the allen bolts that hold the cam bearings down. i'd do it. good luck, chuck.

Fixed! Tick is gone!
 

Well I replaced the rocker with the $22 part from ebay

and the $60 part from amazon to compress the spring. (really well made part FYI)

And this rocker came off easily....almost too easy thought I broke something!

Shows a little wear, haha. I can see how the tick happened with that much clearance.

I took some 200 then 400, 800 and 1500 grit and smoothed out the cam.

The whole problem started due to a blocked oil drain tube above that cam so it wasnt getting oil at idle. Also got those replaced for $10 for both sides and simple fix, just the parts have to be broken off to replace them.

I was almost hoping the thing would tick so I could be done with it and just part it out.

SURPRISE, no tick at all??

I am thinking of changing all these out on my 560SL after how easy it was and I have the tool.

I will change the oil since all kinds of junk got in around the valve covers.

Easy fix for a car with 170k mile that has many other issues....

Thanks for all the advice and help!
