hi all anyone know if there is supposed to be a gasket fitted between the exhaust manifold and the cylinder head as i have removed mine to paint them and found no gasket fitted to both of them

No gasket, just smeer the edges with firegum, or something similar, before refitting.

As standard on these old engines there was no gasket fitted. The flanges were supposed to be coated with Rocol J166 which is similar to Copaslip. However, engines made since 1993 were fitted with eight individual gaskets which are easily obtainable from any Land Rover supplier, and its not a bad idea to use them as they eliminate leaks.

They are supposed to have a raised line running around each of the the exhaust ports on the manifolds themselves. Mine used to until my 'helpful' local kwikfit decided to 'reface' them for me with his angle grinder when he was replacing the manifold studs. Full of pride in his work when he told me the faces were all 'lumpy' FOOL!!  I wouldn't have minded too much but I had ti have them refaced again to get them all straight.... |

I think these engines were designed to chuff around the manifolds. When I fitted the 8 individual gaskets, it improved the engine both from a noise and performance perspective so I recommend using them.  |

Looked at the gaskets today and it appears that all eight are the same, if there is a right way and a wrong way to fit them they should be handed otherwise as pat says they will be fitted the wrong way around

There is a right way and a wrong way I put one side on my mate put the other side on Out of 4 i put on ,three were blowing When we tooK the manifold off to change them i could see the soot This is off Rpi site Although it may seem obvious, which way round you fit the exhaust gaskets, it is very possible to get it wrong, We strongly suggest you check [& double check] the correct alignment as the following 2 pictures will show, getting it wrong has serious power loss implications.  It's clear to see just how wrong things can be. The problem is not 'the wrong way round', but 'inside out & the wrong way round'!  Surprisingly enough, exhaust blow was not a problem but power was 40% down (minimum), especially as rpm. increased. I hope this helps |

I can understand wrong way round upside down but not inside out? the gasket composition is the same on both sides! well they were on mine |

Ok there is a quick answer i think, the gasket has a smooth flat side and a bevelled side what side goes where?. That said the problem i have is that two gaskets go one way (flat side) and two go the other way (bevelled side) again are they handed

My gaskets were the same both sides! looking at the pictures it looks like those gaskets were fitted upside down? you can only fit them one way otherwise you get gasket poking out I would have thought  |
