x flow roller rockers
MkII - 24/1/09 at 03:17 PM

i have just fitted a set of titan roller rockers to my 1660 x flow and have found that the back of the rocker arms are touching the std steel rocker cover on full lift. has any one else experienced this. i have considered panel beating rocker cover to achive clearance but how much clearance do i need and you cant see how much clearance there is once the cover is on. any suggestions other than fit alloy cover as my upgrades list is allready bigger than my bank balance. thanx m.

On the cheap i would fit two gaskets lol.

But seeing as you have forked out for roller rockers, id go the whole hog and fit an alloy cover!

I would imagine for the same reasons that anyone else would fit them; more lift and less frictional loss.

You could see how much clearance is required by simply removing the rocker cover and tuning the engine over until you have max valve lift, then measure the maximum height of the rocker from the surface of the head. Subtract gasket thickness from this measurement and compare with the depth of the rocker cover.

Roller rockers require an alloy cover. You can pick them up for £20 used. "Why spoil the ship for a halfpence worth of tar..."

Mike. its not height thats the problem its the back of the rocker arm just above the ball shaped bit on the bottom of the adjuster on full lift the rocker arm touches the side of the cover ----------------------------------------------

what MikeRJ said plus my rocker gear was quite worn so I decided to upgrade instead of replace. plus they were s/h, theyed done next to nothing and they were very cheap

also they are supposed to decrease guide wear due to not imparting sideways force onto the valve like what non-roller rockers do.

Ahh I see, that would be more awkward to to fix. Might be worth keeping an eye on this one.
