I've noticed over the last 6 weeks or so one of the tappets is a bit noisy in the morning. It eventually goes and all is well. However I've noticed recently that it seems to make a ticking sound a lot more often now, even when the engine is running.
It seems to happen when the engine is under a bit of load, like if you kick down.
Anyone got any ideas? I use Mobil 1 0W/40 so I could go to a slightly thicker oil (Mobil 1 is available in 15W/40 I think) which *may* stay in the tappets and not pass down into the sump, or its a case of writing someone a blank cheque for a new set of hydraulic tappets!
The engine has run faultlessly for 105K, apart from the MAS sensor failing at 98K.
I have had this problem before with a previous car and the dealer changed all the tappets (this was a 4 cyl engine so impossible to trace which was the offending one), but I had this done under warranty. Somehow I can't see MB honouring this work under warranty...
Thanks for any advice,
Greg
