I pressume this is not a performance enhancing breather hole in the under side of my new inlet manifold I noticed it today when wiping round the engine bay as there was some staining appearing on the flat area. If I put a torch underneath you can see light from the top with the carb off Definately dodgy casting as the hole is smooth on all all edges and appears to be a splodge rather than a crack. I now soley blame this for my runs of low 16's on Friday and not my wheel spinning agressive starts Looks like I'll be calling the supplier in the morning

Poor quality control there! They mass produced or a one of job?

Took ages to work out what was going on in the first pic, then I realised it was a mirror!

Yeah sorry I always do this on here, get the pictures the wrong way round every time. If I ever get round to putting pictures up of what I do to my car it would look like I'm taking a perfectly good car apart and replacing all the parts with broken bits Mind you with this Edelbrock RPM Airgap that's exactly whats happened

Does it go right through? You can see light or poke a wire through?

Yeah it goes right through I have a video with a torch underneath and you can see light inside with the carb off. I didn't notice it when I installed it cos the hole is difficult to see even from upside down. To honest I seem to remember un packing and fitting straight away, doh

That would have knocked your tuning all to cock.

I'm guessing that could be why the idle screws have little effect?

That is one of two things that would cause that yes. The other being the throttle blades not being closed enough.

If you didn't get the manifold from a UK supplier then I would just have it welded up. Or just epoxy a patch over it with a fuel resistant epoxy.

You might even get away with a fibreglass patch.

Obviously it would be tricky to drill and screw a patch over it due to the difficult access.

You did well to find that, not an obvious fault.

I would get it welded up or drilled and tapped and a plug inserted for quickness..........I have some very high quality epoxy that would do it, but I do not know how long it would remain fuel resistant........you are welcome to try. I am not a million miles away.........

If you do contact the supplier James, let us know how you get on. I'd be interested to hear how keen they are to supply you with a good new one, f.o.c.

Mancini racing sent me the wrong manifold once - their bad that they put their hands up to. They sent me the correct one and I was advised I could keep the other one; which was nice. Top service really...

Hope you have as much luck, don't offer to return if bought Stateside, the shipping will kill you.....

Plus you will pay VAT on it again.

Not sure you will get access to the underside with that being a small block air gap manifold.

Do it from the inside...

Oh I thought it was further down the runner than that.
