1992 300D White Smoke, Clicking Episode
My 92 300D has worked flawlessly (other than garden variety repairs) over the last 110,000 miles....currently has 244,000. This afternoon, my son was pulling onto highway, hard acceleration, and heard a clicking sound from the engine compartment and noticed LOTS of white smoke coming out the tailpipe. So he pulled over and called me.
I was able to replicate the symptoms and drove the car four miles home. However, by the end of the trip the clicking had stopped and the white smoke almost disappeared. Oil level is fine, coolant level is fine. Earlier in the day, I replaced the o-ring on the stop lever. Can't imagine I could have messed anything up on the IP, but who knows? Also, I added a quart of dino oil to a system filled with 5w40 synthetic (I have an oil leak somewhere and didn't want to dump in liquid gold). As I read some threads, I thought I'd toss this out and see what anyone's thoughts are. I also notice an oil leak by the #1 exhaust pipe. Thanks.

I took the car out again, maybe an hour and a half later....engine still warm. No clicking, no smoke.
Took it out again early this morning, thinking that perhaps clicking and/or smoke would reappear with a cold engine. Car runs fine. So that's good....but I'm still stumped.

Is there any chance that my replacing the O-ring on the stop lever could have temporarily introduced some air into the IP? Could that be the cause of the problem?

Whatever you do...
Don't ease up with the monitoring or it could be costly. But you know this.
WRT the SDL, I'm down to checking fluids every third trip. I'm constantly hawkeyeing the temp gauge and have had multiple noises, some fixed, some not and those that have faded on their own. So far so good and so paranoid on my part, but I'll accept that in lieu of the alternative. Only clicking that persists is a tappet on cyl2 about 50% of total drive time. I'm hoping the syn will correct it, but it's only had 1500 miles to work at it thus far. If I had a episode similar to yours then I would be extremely cautious. Air in the pump is possible, but not likely IMO. And it doesn't explain the smoke. I would definitely research the oil leak around exh1. There is something to be found here, I just can't recall specifics. MBZ123

FIRST thing I'd do is pull the vacuum pump and verify it's pristine.

ANY time clicking or really any issues are found on an om60x motor, I suspect the VP first. likely it's simply air in the fuel causing the issue, but your new VP has 200K on it... inspection is a good idea.

White smoke makes me think of injector timing or low compression.
Could be bad timing chain. could be stuck valve. Or many other things. Need many more details.

As the other Member said a sticky Hydraulic Lifter could account for the tapping; and I think the the Smoke.
You could also have some bad Fuel or even some Water in the Fuel System. When that passes through it could knock a little and cause a smoke issue. If the sound shows up while the Car is idling try to locate where the sound is coming from. Use a piece of Broom Stick or a large Screwdriver against the parts and your Ear on the other end. Start with the Vacuum Pump and keep your Face and what you are listening with away from moving or hot Parts.

Took it to the mechanic where I have most of my work done. He believes it's a head gasket failure with oil entering the #1 cylinder. It's been quite some time since he's done a head gasket, so there are a couple of other shops further away that I would have do the work....if that's what I decide to do.
I'm not opposed as such to dropping a chunk of change on the car. But I do worry about other damage that's already been done....and the wisdom of spending $1500 or so into a car with 244k on it.

has the water temp been normal during this episode? and has the level remained the same (not needing to be topped up?) If using water then possibly a cracked head but also could be the head gasket.
I was also going to suggest it was a head gasket. The mileage really not a factor, if the car is in good shape and you like it then thats the price for keeping it running. Lots of gassers have head gasket issues too. I would also have the head skim cut and pressure checked, if off to replace the gasket because you don't want to throw the labor onto a head with possible problems.

Water temp and level have been fine.

Injector is nailing my bet. Does it white smoke at idle?
