jas98 Member 1,043 Member For: 12y 5m Gender: Male Location: Maryborough Qld Posted 23/03/15 02:38 AM Share Posted 23/03/15 02:38 AM Ba xr6t stock.At startup massive ticking sound at startup. If idle for a while comes good but can still faintly hear it every now and then especially when accelerating lightly. I only started noticing this noise loudly after I accelerated quickly and as it was boosting (6 psi) there was a pop sound like a backfire from engine area....could be completely unrelated though. Also seems to be running slightly thirstier. But allot of things could be causeing that. I'm thinking exhaust manifold gasket. I'm hoping it's not the timing chain guide f*cked......Any ideas? I'll get a recording of it when I start it up cold again although does do it when warm startup but not as bad Link to comment Share on other sites More sharing options...

Had mine changed out about 1 1/2 yrs ago. Link to comment Share on other sites More sharing options...

Will rip off heat shields and have a look.Forgot to get a recording thismorning but started it up with bonnet up and f*ck it's really loud. Gradually Came quiet after about 3 min then when lightly roving it I herd it for about. Second.Anyway the noise is coming from the front part of the Manifold closest to power steering pump. Also can smell exhaust fuels. Hopefully it's the type of gasket I used a couple year ago not sure. Worst case timming chain? Or would timming chain do it all the time?Will keep updated Link to comment Share on other sites More sharing options...

This is usually with modified cars though.Get those heatshields off asap to confirm manifold issues but in the mean time I'd stay off the boost.

He said straight away manifold leak so I'll have to confirm it.Bidets is fat? Similar but not the same. My noise is more of a tap tap popping sound that sound sounds like a timing chain?? Or belt tensioner f*cked? Link to comment Share on other sites More sharing options...

Spary some inox into or around the plastic bit on the belt tensioner. It might be dry. I did this and the noise was gone. $5 a can and could piss the noise off. But without a video with noise its a needle in a hay stack. Link to comment Share on other sites More sharing options...
