HELP?! RB20 New head on - badly clicking followers?

[TurboX]

Guy's just refitted head on the RB20 and found on starting that there is a loud tapping/clicking noise like the cam followers not pumping up.

DAMN was I supposed to line up the holes in the followers in the side oil rail??

Only just thought of this after hearing noise. Do I have to take the cams back out;-(

On a positive note the idle is smooth even with the 550cc RX7 Injectors and mod AFM Box to try and compensate -looks like it worked, will have to dyno asap.

Any comments appreciated and I promise to do a search soon.

Have you driven it yet or was that straight after startup?

Common thing with everything from RB20 to RB30

Will be noisy for ten to twenty minutes unless you prepped them first.

You will find that a nice drive around the block will quiet them up. If it doesn't then you may have other problems.

Hi 3LIT3 FORS3, thanks for that, I was starting to get really worried I would have to pull the cams again.

I had only started it about 10/15 times for a few min to get the oil going through the new cooler and to make sure the new 550 cc Injectors were operating OK.

Last time I tried them they were frozen up. This time they are all OK!

Aparently they dont like sitting around for a few months before you use them

Thanks again, will drive it soon.

I'm sure you will find as soon as it drives around a bit after the oil temp and pressure levels reach their operating values, the noise will disappear. It will go away if you let it sit for ages idling (like half an hour - sometimes sooner, sometimes never). With every one I have done, it has taken a drive around the block to clear them up.

Good luck with it
