Just to echo what's been said.

Water pumps and 'p' gaskets are favourites on the 300.

Have a good hunt around the front of the engine and look for signs of leaks.

If there was a leak on the head gasket, surley i would notcie a drop in power and performance? which i havnt.

Had to change the power steering pump earlier this year, so looks like the water pump 'P' gasket is next - dare i sask tho - is this a hard job !!!!

ChrisW:
Problems with the cylinder head may not generally manifest themselves as the head gasket going - my cylinder head gasket was perfectly fine, it turned out the cylinder head had a crack between the water jacket and the exhaust port - the only evidence of there being a problem was the overheating, the water level dropping and steam coming out of the exhaust.

ChrisW:
To replace the water pump / gasket see below - the P gasket is actually mounted behind the 'second half' of the water pump - the cast aluminium section that looks like part of the timing cover - this comes off seperate to the timing cover (fortunately) and the P gasket is located there.
If you replace the P gasket make sure it is the 'uprated' metal gasket designed to overcome the problem of this gasket leaking.

joe90:
Thanks for the chris, im off down the local spares counter to get the bits, will have an ask. Theres no steam coming from the exhaust, so im confident it is this problem

Will let you all know one way or another, looks like i can finally use my new socket set santa got me  :lol:
