Planning on changing my rocker gasket on my phase 1 (CF1 engine with aluminium cover). I have the replacement gasket, however I'm wondering where the best place to put gasket sealant is when fitting the new one. Should there be a continuous line of it all the way around, or does it just need a blob in specific areas (e.g. the corners)? What about for the separate smaller gasket around the spark plug area?

Is the seal rubber like on the cf3?

By the seal, do you mean the gasket itself? If so yeah it's a rubber gasket. CF1 is 2 piece though - one outer gasket and one for the spark plug bit. not sure about the CF3

Then I don't think you need any sealant, the gasket is enough.

RTV sealant in the corners where there is an abrupt change in direction, the cam carrier at the cam wheels end and only small blobs at that. Nothing elsewhere as the gasket is sufficient to ensure leak-proofing.

Thanks for the replies. I'd read on here that the CF1 is more prone to cam cover leaks than the CF2/3 so will apply a small amount of sealant at the bits suggested by armoore.

I had a leaky cam cover, new gasket and following the advice worked for me

Also don’t forget to follow the torque down values, too little and it may leak, too much and you break a corner rendering it scrap

Where do you get the torque down values from? Thanks
Not sure if they're in the GTV/Spider workshop manual - it's on my other laptop so will check later. I believe they are pretty low (maybe as low as 5Nm or 7Nm). This is especially important for the CF1 with the alloy rocker cover as there has been instances of the cover breaking if the bolts are torqued too much.
