I replaced my valley gasket today. It was leaking at the back. Here's why! Both end seals are absolutely knackered. One is split right down the middle.

They're only 18 months old. Either I bought really **** parts or (more likely) the torque wrench I used to tighten down the clamp bolts was duff so I over tightened them.

I can't think of any other explanation.

Wow! Are the metal clamps ok & not deformed? Is it 20Nm from memory, but i just used to nip mine up but ran a thin bead of RTV on the underside of the gasket as well as the notches.
 
PS, did you trim the small V sections on the end seals? I found them too big for the notch between the head & block & lifted the valley gasket making fitting the upper intake 'fun'. I imaging there would be plenty of force on the rubber as you tighten the intake down & possibly split it. The Turner end seals were ok but Britpart were too big.
 
I've used new metal clamps this time just in case.

They're 17Nm. I've put a bead of Permatex along from one notch to the other. And a little on top too.

No trimming necessary I didn't think. But I bought Land Rover original seals this time. No ****ing about!
 
Try blasting silicon lube down the centre air vents after removing the plastic vents. Must be silicon lube though. Usually frees up my flaps!
