SO i recently rebuilt and boosted my SiR2, and for some reason it sounds quite tappy on idle.

It's had:

Wiseco low comp pistons, acl bearings, eagle rods
Skunk valve springs & retainers (standard valves)
RC 550's, AEM fpr, golden eagle vac manifold.
Standard head & cams, just a skim and pressure test.

Before the strip down it sounded fine and if i can remember had compression of 175psi across.

At first i thought maybe it's the pistons expanding from cold but ruled this out when the car warmed up. I know the injectors pulse louder but it's not them also am ruling out piston slap as the car idles nice and runs nice except the tap.

The car has only been on a 2 mile test running a basemap on Hondata s300 which it ran perfect except this tapping.

I searched and read a few posts regarding lma's so i decided to strip it down and check them, they clicked when pushed down but sprung back up with no problems. I did start to think that as these have never been removed they could have possibly dried out due to the head being off for a few months.

I popped upto Honda who quoted me £40 each without vat!

I know you can use lude ones & gsr versions but thought id post this lil vid to see what you guys think?

Should i bite the bullet and replace them all or just leave the old ones soaking in oil for a few days and try my luck?

Sorry for the long post, just wanted to include as much info
