Knocking from the head

Hello everyone, Iv tried searching for this first, although finding a couple of topics I'm not really any wiser :(

 

OK the cars been off road for about 8month now, the car run fine a few days ago before i took the manifold and turbo off (the manifold had some work done so had to be removed)

 

Anyway I took my time putting everything back together nice and tight so it didn't have to come off again, once I turned the key it started fine but then the engine got warm I could hear a knocking from the exhaust cam area.

 

I'm sure every things tight and put back on right so I cant understand how this could happen when Iv not even been driving the car :(

 

Its booked in with Ryan next month to be mapped to :(

 

Can anyone shed any light?

sorry to here your problems bud, is the knock rpm related, is it there all the time or does it come and go, i ask this because mine developed an intermitant knock from the top end many moons ago when it had been laid up for a while, i have no idea what it was but i did an engine oil flush and oil change and it never came back, scared me to death

It takes a good ten min to start knocking from cold and it is rev related.

 

Time for a flush I think!

 

A mechanic's been to look at it and said its just the noise from the cams with the breather filter being fitted and I'm being paranoid...
