tap-tap-tapping on the manifold

[trinitycall]

hi,

just a quick one. the aa man has noticeda tap-tap-tapping on the manifold. he recommends i get it done. says cars ok to drive.

he says it's caused by exhaust blow-back. however my question is - is it really ok to drive with blow-back? or should i garage it until i can book it into the garage?

Regards,

N

It's fine, just get em tightened when you can (see manifold removal thread)

[trinitycall]

i was pretty worried only had my chimaera 24 hours.

it certainly is more interesting than the merc.

My Chim' is going in to Dave Batty's to address this. Will let you know how I get on either here, or hopefully at the Surrey meet.

Cheers,

Steve.

Steve,

please let me know how you get on, especially re: cost.

i've also booked mine in with David Batty (next week) for manifold crack, full service and other bits and pieces.

Thanks,

Summary so far. Near side manifold gaskets replaced and a crack in the manifold welded up. Spoken to David and the bill doesn't sound too bad. For the most part - a few hours of labour needed.

I've had tapping coming from mine for over a year now. It's on the list of jobs to do, but pretty low down really!

Pretty common complaint with our cars apparently. Sometimes it can just be a exhaust manifold gasket blown, which providing the manifold comes off OK is a pretty cheap job, Or, it can be a crack in the actual manifold (which mine has). Which is a bit more expensive.

I presume a cracked manifold can be welded instead of being replaced - anyone?

Mine's got a hole in the middle of where the 4 pipes join to the large pipe, probably a nightmare to get to?

You need to get out more .

Mine wasn't just the gasket, it was a small hole in the manifold as well. David also mentioned it is quite common and it be welded up - that's exactly what he did for me, since the manifolds were otherwise in good order. The welding is a few extra hours labour, so not horrendously expensive.

Hope that helps,
Steve.

Recommended technique is apparently to remove the Y piece and weld from the inside.
