TXR05 Member 181 Member For: 13y 11m 29d Gender: Male Location: Brisbane QLD Posted 20/04/12 05:59 AM Share Posted 20/04/12 05:59 AM So, I'm sure some of you have seen my other thread about the possible VCT problem. Well I can hear and feel a tap in the head around the green circle area. It's not the injector of coil, I've already listened to them.I can feel a tap in the head, like a nosiy tappit... Under the black plastic, can't feel on the side of the head though, only on the top where the noise is coming from.What can this be ? Can this be the possible problem to my lost power ?Thanks.

So start with the head first and go from there. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/79802-loud-tap-in-the-head-can-feel-when-place-your-finger-on-the-head/#findComment-1225186 Share on other sites More sharing options...

The circle is where the tap is coming from.I removed it and heard it with a tube to my ear. I only have insulated drivers.

Bent rods tend to like breathing fresh air An option if you need to use the car and plan to do up the turbo motor is to get an NA motor cheap and chuck it in. Just run the vacuum hose from the front of the turbo straight to the standard actuator, bypassing the boost solenoid and it will run 4psi.I'm getting a bit ahead of myself though. First thing is to identify it properly Edited 20/04/12 10:11 AM by riptide Link to comment https://www.fordxr6turbo.com/forum/topic/79802-loud-tap-in-the-head-can-feel-when-place-your-finger-on-the-head/#findComment-1225356 Share on other sites More sharing options...

Only a very light knock, like a noisy tappet.You really think that could be a bent rod? even though my limiter is 5500RPM, and I never even hit that ?

Noisy tappets isnt a very common issue with these engines Link to comment https://www.fordxr6turbo.com/forum/topic/79802-loud-tap-in-the-head-can-feel-when-place-your-finger-on-the-head/#findComment-1225408 Share on other sites More sharing options...
