i have been told the clevo has a simerlar system to the crossdlow with a prioty cam then main/bigend oiling system.
and this cause the same problems ive been having with main and big ends wearing very quickly.
i have also been told there is a plug kit for when you swap to soild cams that reduce's cam oil and increase's supliy to the crank and rods.
does anyone know where to get it from or have more info
thanks mark

Do some searches on net on restricter kits which is what most call them and they are designed to maintain even oil pressure throughout the block just as reducing and increasing air con duct sizes maintains air velocity in office blocks. Most performance shops should be able to help you out.

On a performance street engine this isn't an issue...
Iff all clearances are correct..
Restrictors are used with mech cams...
