Watch for water in the oil, oil in the water, white foam in the oil breather. But you might be fine. So my plan tomorrow is to go buy two more gallons of Mobil 1 15w50 (which is what I was running anyway) and change the oil. If the worrying tick remains I'll add Lucas oil additive (which is just viscosity improver) until the noise goes away. Years ago my cousin let his sister drive his Ford LTD (the horrible little one) while he was away at college, she never added oil and the engine ticked like crazy. He changed the oil and put in 2 quarts of STP until it quit making noise and drove it for years like that... Err, not applicable. The Ford would have had hydraulic lifters. The OM616 does not. Valve ticking on an engine with hydraulic lifters can indicate the self-adjusting mechanism isn't doing it's job and thicker oil can help that problem. With solid lifters like your 240 has, it can't do the same thing. Like Mitch said, maybe it's time to check valve lash. Yeah, I know - fun job in the snow. It's supposed to be done with a cold, cold engine - but if it were me, I'd probably run the block heater to warm the engine and help alleviate cold fingers. Just set the lash a bit tighter. -- Philip ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
[MBZ] Another piece of good news
To facilitate the alternator removal I'd parked the 240D next to the garage up on some 4x4s but we've got 6-12 of snow in the forecast so I figured I ought to make sure its mobile enough to at least move for snow removal. I ran it some yesterday both to make sure the alternator still worked after re-installation and as it was nose up to hopefully make sure the cooling system was completely bled. Again as with yesterday the car fired right up, its maybe 25F, and idled fine with merely a small worrying tick somewhere in the valve train. I backed it off the blocks (I'd made a ramp with some 2x6s and firewood for supports) and removed all the blocking. Since the engine didn't seem warmed up I took it around the block. The worrying tick goes away at low speeds but comes back above about 2500rpm but other than that the car seems to have proper power and if anything the throttle responds a little better than it did before.

Re: [MBZ] Another piece of good news
Sometimes you get lucky and sometimes you don't. Though I suppose ticking is better than knocking.

Maybe your valve tick has a more obvious explanation.
