WideSam Posted August 22, 2015 Share Posted August 22, 2015 Those are for the coil packs Sent from my iphone using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted August 22, 2015 Share Posted August 22, 2015 The earlier wrx and sti models have separate coil packs that sit on top of each of the spark plugs and those are for the fixing bolts . They're unused on the later uk and wrx based varients which have a single coil pack attached to the inlets Make sure you get the correct version rocker cover gaskets for your scoob and replace the "half moons " at the back of the cams at the same time [emoji6] 1 Quote Link to comment Share on other sites More sharing options...
nunny71 Posted August 22, 2015 Author Share Posted August 22, 2015 ahh spot on thanks for that I didn't know that the half moons could be replaced, are they easy to pull out and fit new one on . or are they gonna be a bugger to do ? Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted August 22, 2015 Share Posted August 22, 2015 Easy enough to do once the cam covers are off bud . they're made from rubber so they go hard and brittle and eventually weap , especially the one near the upipe due to the heat. I bought a new full oe cam cover set from import car parts as they're about the cheapest for genuine oe gaskets . I smeared a light bit of liquid three bond on all the seals but as long as the oe seals ain't squashed (bolts over tightened) and both surfaces are Uber clean with no deep scratches they shouldn't leak for another 50k + or until they go brittle again 1 Quote Link to comment Share on other sites More sharing options...
