Whats probably happened to the Aston engine is that the original V12 was two Ford Duratec V6's similar to ST220 spec where nailed together and modified further by cosworth themself. Late DB7's and all Vanquishes probably didnt have the problem. But when the DB9 was introduced, with intent to sell in large numbers, Ford probably stuck their noses into engine development, shat themself and specced lower parts. Loads of companies do it all the time. Shame really.

glad to see it all done now matey,landrover developed a multi layer head gasket with steel dowels and a new oil rails. The majority who have done this on mg-rover.org have not had any further problems. You want to try and get hold of some vhpd throttle boddies of the elise 190 or of the mgf cup cars. Am looking for these on ebay at the moment the last set went for about £60 which is a bargain. Anyway looks good

Thought thy were superb engines, apart from the Head Gaskets that fail on a regular basis? Yer tis quite a good engine tbh, just a nightmare for hgf. There is a 6 layered hg you can buy that also solves any problems with hgf......

The K series was a 1/2 decent motor - it was light, made decent power and was pretty tunable - its just a pity it was made by penny pinching Rover....  Ive heard a few reasons as to why these engines suffer from HGF.. The locating dowels where of very poor quality and the head could "walk" The Head bolts where of very poor quality meaning the head could lift The engine has a very small coolant capacity - not good when the alloy block needs a lot of cooling The thermostat is very close to the engine - the engine heat opens the stat and then the cold water closed it making cooling unstable The thermostat could not open enough to flow enough coolant - when they resolved this, the water pump could not flow enough coolant.... Rover just couldnt get it right and hence the reason Lotus moved to Toyota for their Elise engines.

Took it for an MOT the other day (NOT at Walsh's in Birkenhead) and it went through with a few non-serious advisories.
