How tight should a cosworth cambelt be?
Iv just bought a 4x4 saff and looking for a little bit of adivse.
I took the cambelt cover off today and when you press down on the top of the cambelt it goes up and down quite abit as if its not that tight, im assuming it should be quite tight? And when the engine is running you can see it going up and down, is this correct or not as i think? If you understand how iv expplained it!
Hope someone can help, thanks

they are quite loose when cold mate!I done mine to tight and it eventually knocked out my front camshaft bearing
as a general rule get hold of the belt (oppisite the tensioner)and you should be able to turn the belt 90% fairly easy any more its prob to loose

you should be able to twist the belt 90degrees
between the inlet pulley and crank pulley, half way between the two, twist it,
if it is too loose, twists more that 90 then it may be good to undo the tensioner belt, check the tensioner and then re tension the belt,
hope that makes sense

It wqas from cold yeah, hope fully ill be able to get it into nms this week, its been run in and that on an engine dyno 1200 miles ago, but just want it checking over for peace of mind reallly.
Thanks for your help.
One more question if you dont mind, where the turbo oil feed comes from the block a slight bit of oil is coming out, and aso the pipe that goes to the breather that comes out on the left hand sidenear the back of the block. Will this most likely just be this hose needs the jubille tightening? Its a brand new 200 block so it wont be anyything wrong with the block
Its quite a step coming from an rs turbo to a cos, there alot more complicated lol
