Maercedes M111 1998cc 16 Valve Engine Ticking
Discussion
Hello all,
I have just purchased a Vito 113. It has a 1998cc M111 Engine that today I started to strip ancillaries off to find the cure to a "Whir
ing noise", and a constant tapping sound on the top of the engine.
I suspected the tapping to be a worn camshaft, but after taking the rocker box off the cams look like new, bearing in mind this has done 96k they are unworn. If anyone would like pictures feel free to email me.
Anyhow so I need to locate this tapping, and the next area to look is the "tappets" or cam followers isn’t it?
Is there any way to find the culprit in the bank of 16?
Also more alarming is "whirring noise", its not anything external ancillary as I removed the belt and ran it for a few seconds.
This totally bemuses me, I am quite practical and although this noise seems to be coming from the crank area / timing chain, could this be an over tightened chain, it feels with fingers right?
today I flushed the engine with Wynns, and then some from GTX Magnatiex. Still ticking away.
Lastly (sorry to go on) where on the internet is there a manual for this engine, it’s surely quite a common, and from what I can see they are nicely engineered.
Many thanks... Justin

Ticking is indeed the cam-follower. You will need to check the cam to follower clearance for each valve in the full-closed position. You will probably find that one is way off which gives the ticking noise. My AJ6 engine in the XJS has a bit too much clearance on one exhaust valve, but I'm being very lazy about fixing it, so I've got the same ticking!
Can't help on the engine. Tried google?

Good luck with this one, if you have to take the cam tensioner out you will find out just how much fun this engine is.
If you need any advice on it, feel free to email me, i have a Vito 113 and have extensively modified the engine.
The problem you have does sound like tappets, they are rather expensive. Has the engine sat idle for a long time?
