Holts Wondaweld
Discussion
I have a coolant leak from, I believe, the timing cover of my year 2000 Chimaera, there are no obvious signs of head gasket failure. I'm thinking of using Holts Wondaweld as a temporary cure so that I can drive the car to my nearest specialist 60 miles away for a permanent fix but I'm concerned that the instructions state "not suitable for engines with piston liners" Has anyone tried Wondaweld or got any thoughts about my using it. Thanks in advance, Paul.
Have you checked for a sticky substance coming from the small hole in the water pump shaft area.
This hole emits coolant if the first seal has failed, the shaft has two seals, the hole is between these two seals. It’s like a warning device your water pump is close to total failure.
It often drips out when engines hot and splashes allover that area, often tracking down and between the chassis brace bars underneath and out onto the floor.
Two water pump bolts got through water jacket in that area which can also be a leak point.
I wouldn’t put any sealer through a Tvr cooling system myself. I’d not use one that is not designed for linered blocks.

This man knows ^ and so do I just dont , your just offsetting the inevitable 
get it fixed properly If it is leaking by the timing cover, It's quite a straight forward fix, no that complicated, but a bit lengthy. I took my time over it and enjoyed myself !
As your in Whitchurch, there is a closer TVR specialist to you than 60 miles away. Not sure if they are any good as I do my own spannering when I can.
