BF6 Member 333 Member For: 14y 1m 18d Gender: Male Posted 24/08/14 01:13 PM Share Posted 24/08/14 01:13 PM Hey guys I could hear every now and again what sounded like the timing chain hitting the rocker cover when I start the car so I pulled the rocker cover off tonight and sure enough the black plastic guide that sits between the cam gears had snapped off. Luckly I found the guide I one piece and somehow it hadn't fallen down Into the timing cover or worse stuck between the chain and cam gear. The car still runs smooth as and hasn't jumped any teeth but there's a nice rub/groove mark on the inside of the rocker cover from where the chain was hitting the rocker cover every now and again. My question is what causes the guide to break and do I replace the plastic guide with a genuine replacement and run the risk of it happening again or does someone make a metal/billet replacement one? I know Atomic make a aftermarket bottom tentioner but what about a top guide? Any info or advice would be greatly appreciated. Cheers Link to comment Share on other sites More sharing options...

Sort of a click click click going around like something was hitting on the belt. The car was parked on a decline with nose down overnight. Only lasted like 20 seconds then stopped. Did it again Monday morning very briefly and sounded like it was external near the power steer pump. Cold start this morning - no problems. Syphoned out the p/steer res this arvo and replaced fluid.I just figured with nose down maybe it took a while to get oil pressure. Then Monday if definitely sounded like it was external but internal noise does travel. Is definitely power steer pump side of engine though. Got me worried now as I have a track day on Father's Day. 1 Link to comment Share on other sites More sharing options...

Mr_4.0 Member 1,096 Member For: 13y 11m 3d Posted 14/09/14 06:53 AM Share Posted 14/09/14 06:53 AM Very common. Just happened to mine recently and the guide went around with the chain and the timing jumped a tooth. However, now it sounds like its happened again only a few weeks later....
