was the water pump leaking when you took it to serek ? or the rad ? or what ?
back then you had a visible leak which I assume was resolved and the minor coolant loss is proving hard for you to find ?

No leak found...

Certainly the misfire at cold start with coolant loss is indicitive of water getting in the cylinder/s :-X
Surely that would lead to excessive pressure in coolant system, seeing as cylinder pressure are way more than coolant pressure.


it's showing exactly the same symptoms mine did.
Whenever I solved the external leaks(cap, expansion tank and top hose) the leak got worse.
I was resigned to changing the head gaskets, and got the parts together. By the time I started the job, more steam than normal was visible in the exhaust gases as it warmed up. But it wasn't pressurising the cooling system as much as blown head gaskets I had seen previously.


Removing the O/S head revealed a rotten gasket that was the cause of the leak, and a nicely steam cleaned piston. The other side was in a similar state, but wasn't showing signs of leaking.


If it isn't leaking externally(which can take some time to prove) then it has to be internal.

This also matches, my nice clean spark plug, which is really shinny compared to the rest!

I knew what that video was going to be before I opened the link. You and I seem to have very similar youtube subs  ;D

 ;D Not actually a subscriber of that lot, but have a keen interest in the S Class.  ;)

Nothing on that list is a surprise, and a bit of canny part sourcing and DIY would bring it below £3k...  ;)

Speculating further is pointless until that coolant pressure test is done.

We know (non 1998 3.0l) HGF on V6s are rare, and the MLS gasket is even rarer, so lets prove its not external first.


For reference, both times my MV6 HG failed (not to cylinder, but leaked external), there was no sign of the leak unless it was pressurised. Yet it used a 5l can of concentrate a fortnight.  Both times, absolutely obvious when pressured.

Went to top up coolant this morning, last time drove was Friday. Entire header tank empty, it refused to clear its miss-fire. Previously it would miss for about 5s then clear and run fine. Ran it up to full temp, still would not clear and a lot of white steam out the back and miss firing.

Checked scuttle area even though heavy rain, dry underneath. All coil pack area was dry.

So crunch time now, bargain banger or something newer.  Hummmm

Given your lack of time for DIY, I'd say get something newer. With your current mileage you'd be unlucky if you needed to do anything other than an annual service and topping up the washer fluid.

Then again, there's nothing easier than spending someone else's money  ;D
