I re fit a genuine Toyota gasket myself and then had peter at sbits re do it, both times applying sealant in the right spots. Still leaking. I am tempted to do it again and completely smother the whole area with sealant. .. You can run sealant along the rear edge, I dotoecutter wrote:What bolts are you using? The standard cross head screws are difficult to tighten properly and vibrate loose, I just fitted cap screws to mine to try and stop this.

U just run a thin film of sealant along the metal surface of the head (ie under the gasket)?? or do u put it on the cam cover itself too (in the groove in which the gasket sits)? What sealant do u use mate? I got some locktite stuff which says on packaging only use up to 200 degrees, that gonna be alright? I'm not sure what the part is called but the semi circular clamp thing that holds down the camshaft where it connects to the distributor. One of the bolts holding it down turned out not to be fully tightened. I dunno what torque they should be at but i did it up nice and tight and as it tightened i saw oil being squeezed out from under it. I degreased it all and smeared a bit of sealant around its edges before refitting cam cover. So far so good but won't know for sure for a while. Anyway hopefully I have sorted it, can't be bothered removing the cam cover again!
