#218 of 1173 ...But WHICH lifter???
Aug 07, 2003 (6:17 am)
I have a 1995 E 320 with the reputedly "bulletproof" M104 engine and about 85,000 miles on the clock. Last weekend it very suddenly started sounding like a diesel. I took it to my local Benz guy and everyone agrees I have a hydraulic lifter that is not pumping up. A very rare problem for this engine, from what I hear.
The problem is trying to figure out *which* lifter has the problem. I can replace *all* of them, but remember this is a 24-valve engine, hence 24 lifters at around $50 each. And my technician reminds me that one of the camshafts has the variable timing mechanism making it a much more expensive proposition to remove and replace. If we were sure that the bad lifter was under the other camshaft, even it we could just isolate it to that side, it will be a much easier job.
He took off the valve cover and checked the clearance under each cam, and pressed down on each lifter to see if one sank faster than the others. All 24 of them behave exactly the same.
Does anyone out there have any interesting tricks for identifying which lifter is ticking, at least narrowing it down to either the intake or the exhaust bank?

Make sure that a correct fresh oil filter is being used and all its associated o-rings are in place. Try out an engine oil flush and run the engine on Mobil1 0w-30 oil for a few hundred miles. If that doesn't cure it, use a mechanics stethoscope on a cold engine start to localize the noise to at least the cylinder whoe lifter(s) may be noisy. Good Luck.

Aroundthebenz, re: your lifter problem. Because cams and lifter wear in together, don't you have to change the camshaft when you change lifters? (Or is that just on solid lifters?).
In any case, rather than going for $1200 worth of new lifters, just get them reconditioned. There may be even people out there that stock rebuilt-exchange lifters for sale. The benefit here is you get a fixed price and instant shipment. While you track that down (maybe even calling the Automotive Engine Rebuilders Association in the Chicago area for some names), with your savings maybe you should check into some reground cams?
#222 of 1173 BRAKE DUST PROBLEM
Aug 15, 2003 (9:44 am)
I have a problem with 99' E-320. It gets very dirty with brake pad dust. Thinking of installing "KLeen Wheels" brake dust shield. Any advises is appreciated.
#223 of 1173 Are the Kleen Wheels
Aug 15, 2003 (1:56 pm)
brake dust shields, metal or plastic shields that hold dust in away from the wheels? If so, you're "danged if ya do, danged if ya don't". These shields can decrease ventilation of the brake pads and cause heat build up which, among other things, interfere with the operation of the brakes. What do others know or think about them?

They worked well on my Riviera until the first heavy braking effort from high speed. Warped a rotor, and I can guarantee the lug nuts were torqued to spec.
#225 of 1173 [follow up] All quiet on the lifter front
Aug 16, 2003 (7:27 pm)
Thanks for the advice, folks. My mechanic did change the oil to 10W30 (he doesn't believe in synthetics...who am I to argue?), and within a dozen miles, the lifter noise was gone. (I also heard from another long-time Benz tech that in his experience synthetic oil tends to cause noisy lifters because they bleed down faster.)
I have no idea what grade of oil was last put in the car, but we're back on the prescribed diet and all is well. (Except that my mechanic said that my wiring harness is disintegrating and will need to be replaced soon.)
#226 of 1173 E2000MB wagon single swipe wiper chatter and Tele Aid
Aug 30, 2003 (1:39 pm)
anyone have a problem with the wiper dragging across the windshield when it gets the least bit dry? have had the arm replaced, windshield cleaned of grime and grit and it still drags; of course, on the driver'side so my visibility stinks. MB says the single swipe doesn't allow water onto the cleaned area as two blades would, so wiper is always going to be in contact with a dry area and drag slightly. hmmm..
So, in other words, tough it out or any suggestions?
oh, the Tele Aid problem-- there was a moderate recall on speaker volume which i had replaced and since then it works well.
#227 of 1173 DCHUTE -Re Post 173 Steering Problem
Sep 10, 2003 (6:04 pm)
I had the EXACT problem you had. They replaced the steering and the noise went away...BUT the steering now feels noticeably lighter than it was before the replaced the rack and it seems like there is alot of play in it. I took it back and the said it was normal...I am at a loss since I know the steering is not supposed to be this light (tested other E's).
