hi all,took the rs out at the weekend for a spin,after a bit of fun it started to rattle/tap from the top end then went quiet,decided to take rocker off to check valve clearences and found that it has hydraulic ones fitted so why the noise?its been stood quite a while b4 i bought it and it had an oil change in october so what should i do,i have another engine with solid tappets,is it worth changing them or shall i leave the hydraulic ones in,cheers.

 

One problem with CVH engines are the cam and tappets, they wear together, so changing one or the other is useless. it NEEDS to be a brand new cam and tappet set, OR a 2nd hand cam, with the tappets in the correct order of removal.

If your RSI has hydrualic tappets fitted, and it is a genuine 16i engine (I dont know how to tell) then it could be someone has stuck in a set of hydraulic tappets and left the original cam in, and now the tappets are knackered?

probably worth checking the cam and tappets, to see what the score is, and take it from there.

Also check the rocker studs in the head, these can be pulled out the head which is fairly common, nothing a wurth insert/helicoil wont sort.

HTH

 

if its going to be that much trouble i might aswell just change the head complete with the other one i've got that i know is a good one,annoying though,it runs sweet but every now and then it rattles.i can see wear marks on one of them but nothing serious,decisions decisions,run it over summer with a rattle now and then then do it all over winter or take it off the road now .winter souds good to me.cheers.
