Hi Guys,

Here we go again. It was six years ago that I last removed the heads after a cambelt failure and seized tensioner. A few months ago had a thermostat leak which I repaired (plastic rubbish). I was considering fitting Kaisers metal thermostat but I have been away and then noticed water loss and mayo when removing oil filler cap.
My questions are as follows:-

1. When I took the heads off last time the car had not overheated therefore I just used the latest MLS gasket. However I have read on the forums that if the heads have not been skimmed you should not use the MLS gasket and use an original gasket or composite gasket. All the suppliers have the MLS gasket although DMGRS supply them but have no stock at the moment. As the car has not overheated I intend just to remove the heads and replace the gaskets. Anyone got any views and if I should go the composite gasket route where can they be obtained?

2. Haynes reckons that you have to remove the inlet camshaft sprocket but I can't see why this should be necessary. Is it?

Appreciate any views .

Martin
