Does anyone know what it takes to do timing chains in the ka24det, mine are slapping around. I was wondering if you had to pull the head to do the switch, or if you can get to the chains through the valve cover.
as AW11 & taylor said above, the 'chain guard' plate needs to be removed. it is the piece of metal that hangs over the top of the timing chain, between the two cam gears (very obvious once the valve cover is removed).
take the two bolts out, remove the assemly and the bolts. there is no replacement or recall part...just throw it away, do not put the bolts back in. now, if the piece appears to be cracked, broken, incomplete, damaged, hunt around the valvetrain for it. if it is broken, and u cant find the missing chunks, time to take it to a shop, as it could cause MAJOR damage if not destroy the engine.
AW11's was snapped at the base, and basically resting/bouncing on top of the chain...it was caught in time.
lastly, run 15-40/20-50 oil to guarantee a long like KA24DE
