Hi all, I'm Francois and am down in Cornwall. I have been using this forum for nearly all my landrover DIY and has been fantastic but I have been struggling with a concerning issue and thought I would sign up and hope to pick your knowledgeable brains!

Cutting short a long story- driving on motorway my cambelt snapped, got the Landy towed to the local mechanics where they assessed the engine and replaced all pushrods, adjusted the lifter clearance and replaced the cambelt... they insist the engine is fine but I can tell that there has been a loss of top end power (i.e.-used to accelerate easily to 70mph and now I can't get it over 60mph , also need to change down on climbs which I never used to)... there is a rough idle when weather is very cold which smoothens out after driving up the road.

I have noticed on previous posts mention of checking fuel filter and it should be full to the brim, if I remove the filter straight after my drive it looks to be just over half full, replaced fuel lifter pump and still no change. Any help would be extremely appreciated.

Thanks all.
