Hi all

New to posting but been monitoring the site for a while great site very helpful.

Purchased A 1987 560 SL over the Memorial Day weekend 150 K champagne with palomino interior. Well anyway went away for a couple of weeks and now the car is making a lifter noise passenger side near firewall. Replace the oil with 20/50 W
Wal-Mart brand[ bad choice ]? The taping is slightly better but still very noticeable.
I thought it might work itself out but still there after hundred plus miles.

The question is can there be anything done besides replacing the lifter. Any additives or replacing the oil with a better brand, or is there any adjustment that can be made.

Any help will be greatly appreciated
Thanks in advance JPAL

Re: Lifter noise

Probably not too much you can do...oil additives are not recommended as a cure for any engine issue for any brand of engine, much less an expensive lump like the Mercedes and the hydraulic lash adjusters eliminate the issue of adjustment alternatives. I'd take a peek under the cam cover to determine whether there might be some other possible fault...like a snapped plastic fitting on the oil tube for the cam. If the inspection reveals nothing and it is not a case of the cam lobe wearing beyond the travel limit of the adjuster (really bad news) then I'd bite the proverbial bullet and have the hydraulic adjuster replaced. As for the oil, you might be better off with a good HDEO like Delo 400 15w/40 or a similar high quality brand and viscosity. Personally, I only use Mobil 1 15w/50 in my Mercedes. My only reason for going to Wally World is to buy cheap Mobil 1.

Re: Lifter noise

Thanks Jim

I will take a look under the cam cover. I'm also going to replace the oil with Mobil1
Do you have any idea what the cost of a lifter replacement would be:confused:

Jim

Just want to let you know I checked under the valve cover everything's fine. Removed the old Wal-Mart oil, replaced with Mobil 1 15w/50 after about 50 miles
The taping noise is gone. Great stuff.:Thumbs up:
Thanks again JPAL

Re: Lifter noise

Let us know how the Mobil 1 works out over time. Putting synthetic into a motor that has gone 150K + on conventional oil may produce some...after effects. I've been told that the synthetic will often produce leaks in the older seals, etc. I was advised to stay with conventional oil in my 87 with 100K. I get a little lifter noise on start up, but it stops after a second or two.

Good luck with the SL :Thumbs up:
