can anyone help me. i've got a v4 wrx type r v-limited wrc which has had a 2.5 engine fitted. it has forged internals with acl race bearings roger clark oil pump and v4 sti heads and a vf22 turbo. when i first start the car the hydraulic tappets are really noisey and after about 10 minutes it clears does anyone know how i can stop this or is there something i can put in the oil to treat. any help would be much appreciated. thanks dean

have you checked the oil level if thats ok it prob will be the shims that are worn this would account for the noise stopping when it gets hot

you can buy from any main dealer. They are kinda pricey however...

Version 4 heads dont have hydraulic tappets. Probably forged piston knock.
