Coolant leak from head gasket
Discussion
Just had a service at Hendry's - no probs as usual but they said I had a coolant leak from the left head gasket (rear end).
They reckon on £800-1000 to get both heads off, skim them, and fit new gaskets, and don't recommend doing a trackday with all that extra heat and stress (to the engine, not the driver!).
Anyway, I'm not about to jump in with both feet yet, so has anybody had a similar problem or got any thoughts on this one?
Cheers

If you look in Bible 2 you will see where the offending gasket is probably leaking. It is very close to the oil ways and exhasut. It is likly that it will get worse and either contaiminate the oil or pressurise the cooling and chuck out all the liquid. In either case watch the temp like a hawk and make sure that the coolent is not going into the oil and creating mayo. If so. Don't drive the car any further. Recover it to hospital. If either thing happens you can warp the heads so much that skimming is useless and you are looking for a pair of new heads! Add 2-3 grand to the bill. Definitely worth chceking the state of the rocker gear and cam as the main cost is the labour in removing the heads.
There is a lot more detail in the bible of the fun I experienced last year.

Thanks NC3 - You're not the first to recommend TVR Power, and indeed I booked the job in with them this very morning. Cheers, Mike
If you don't mind me asking, how much did they quote you for the job? I've got a mystery coolant leak that by a process of elimination is looking like head gasket problems (or worse!)
can you not do the job yourself , ie take the heads off and get an engineering firm to check if they are flat and skim if its needed as its not a high tech motor and dont have cambelts just pushrods and get a top end gasket set, just takes a bit of care and a torque wrench and a lot of your time ....
