Risky

How so?

I cant imagine any issues, apart from giving it a little longer to warm up.

If the fix was that simple - I would have thought Landrover would have done that rather than the mod they brought out.

However, I do know that you know the insides of your car pretty well - so I guess - father knows best.

What I do know is that the used car sellers in Canberra used to remove the thermostat completely while they had the 1800 on the block and put it back when they sold the car - that way they know it would not suffer from the theremostat driven thermo shock that would kill the engine. They did that so that the engine would not pack it in when they had it. test drives always had to be booked in so the car was warmed up first.

I know its not the best option, the best is the remote kit. However it severely lessens the fluctuations in collant temperatures, and should reduce thermal shock. So far im very happy with it.

Much more reliable and stable in temperature.

Weellll....

Remember that the head gasket is actually just a symptom rather than the cause of the problems. The cause of the problem are hotspots in the engine which in turn cause the liners to slip as the tolerances it's built to are so small.

So modifying the cooling system does help but it doesn't always cure...

If you are referring to the low grade sand castings around the water ports in the head, i ported them out to ensure high flow around the head. I thoroughly recommend it. The castings around the ports is very poor, and blocks over half the diameter with slag. Easily removed with a dremel or die-grinder.

I am still happy with the thermo mod, it has me much happier. I know it runs cooler, as i tried my heater the other day and its **** poor compared to previously.

Cheers!

Did you see that complete 1.8 body sold on e-bay for only $1200 today - same as yours - colour and all
