Default ZT 190 Water leak Oil filter area

Hi Everybody

I am just in the proscess of replacing the Thermostat Housing as i have as leak somewhere in that area so have ordered a full kit,I know it was replaced 2 yrs ago but something has failed again.I have the common water in the V.
But while i have the undertray removed i spotted what looks like a different leak and its wet on the part of the tray where the oil filter sits.
I have enclosed some pics of where it seems to be coming from it is dripping off the bottom bolt from what i can see,any ideas of what this could be please.

That "something" will be flattening of the 'O' ring seals Jim. When you've fitted everything into place, be sure to move the plastic clips on the straight pipe fully outwards so that they are touching the water pump and thermostat housings. This simple operation keeps the whole structure rigid which hopefully will prevent a recurrence.

In the right-hand corner of the V at the water pump end there is a gap through which standing water can drain. It discharges in the oil filter area often leading people to conclude that the pump is leaking. I suggest that you complete your plastic components renewal and keep that area under observation. It may be a secondary factor of your 'O' ring leak, as it was on my car.

Many thanks Simon,I was wondering if there was some kind of drain in the V and that helps alot,Im betting the coolent from the V is leaking back down like you say,Ok that makes me feel abit better i will crack on and change the Stat and use your useful advice when doing so.
much appreciated Thanks Julian

There is a drain in the V that lets water out in that area so hopefully that is it rather than the water pump.
My money is on the drain.

Update well i tackled the job today keyhole method, What a NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- job took me all day 9am untill 4 pm as i had a few difficulties to say the least,Doesnt help when you are in the street no garage, No problems with the new parts that had been fitted a few years ago but the O rings had completley flattened out thats why i had a few leaks around the stat housing filling my V section.
Enclosed a few pics of my job, What are the 2 wires left and Right with 10mm bolts on the picture of the V section ??
Also some pics of my flattened out O rings causing the problem,Fitted the Clips as close as possible to the stat housing and the Rear of the pump but we will see if good enough,They were a pig to clamp up in a confined area ended up using a jubilee clip to squeeze up the clamp and a screwdriver to get the angle as my grips and everything i have would not go in,Filled the system with bleeder open and tank raised so hope i got the air out, Ran the engine upto 82 degrees in economy mode and checked water topped up a little then ran again ,Im going keep an eye on the water level over the next few journeys.
At the moment V section is dry fingers crossed.
many thanks for the help from the Forum. cheers julian

They're the knock sensors.

You'd have had better access if you'd chosen to remove the manifold chamber but it's not a nice job whichever method is used.
