Land Rover have redesigned the K series 1.8 head gasket and upgraded the lower rail that the head bolts screw into.
The head gasket has lost it's elastomeric beads and now has a laminated type of construction and the lower rail is beefed up - it must have an effect upon the clamping load. Head torque figures remain unchanged.
Picture three shows the very thin metal coated shim that is fitted on top of the headgasket

hi, new member looking for a little advice re head gasket replacement,just purchased a new head gasket kit as per your photos, the kit gives no clue which way the shim fits, ie steel shiny side to the head or the black side to the head, any ideas ?, i am guessing the black side is a coating/bonding and fits to the head side ?, any suggestions would be very much appreciated, regards, alan.
I thought all Land Rover K's were supplied by PowerTrain, if so why did these changes not make it into MGR cars? Have LR been stripping the engines down and modifying them after delivery? Where are LR sourcing there K engines from now if they're still being used?
I don't know what's happening supply-wise at the moment, but LR have to look after the owners of Freelanders with the K Series - hence the redesign. Quite who has done the redesign work is beyond me - it must be LR themselves?
Well it was said recently (either on here or keith's site) by an ex-employee that PT knew exactly what was needed to stop the head gasket problems, but the P4 weren't interested in spending the money. I wonder if this knowledge has made it over to LR?
This is good news anyway, for TF owners in particular.
I reckon the lower rail is stiffer, giving less 'flex'
There is an image missing from the pics above - there is a very thin steel shim that sits on top of the gasket - it is like an additional coated gasket.
All very interesting.
How did I come across it? Ordered the parts from Land Rover. There is a Technical Bulletin out about it - would like to see that sometime. Anybody work for Land Rover? :dddc:
