2.4 jtdm intake manifold!

Hi everyone,

I'm after recommendations of places and an idea of prices for replacement of my intake manifold!
Any views on whether to have the swirl flaps blanked or not?

I have the ally manifold, currently one swirl flap (far right) a little wobbly from worn bearing, but cars still running fab!

EGR has restrictor plate fitted but not blanked!
I don't mind travelling for a good price and experienced garage!

A new manifold for the 2.4 is about £350 but it would be a lot cheaper to have your manifold cleaned out and the swirl valves removed and the holes blanked. Its a big job, probably a whole days labour as it needs the cam belt and fuel pump removing.
Autolusso in Dunstable are well thought of will of done loads of these and not far from you.

Thanks for that, I have family in Dunstable, could kill 2 birds with 1 stone!!
I have contemplated replacing with a blanked manifold myself, then just having the remap done!

You dont need a remap or any adjustment to delete the swirl flaps, you just leave the actuator motor fitted and electrically connected. You do need to delete the egr from the ecu if you fit a solid blank thou.
A manifold change is a pretty big job on the 2.4, aswell as the fuel pump coming off aparently the pump bracket needs to be loosened and moved to remove the manifold.

Or you could fit a plain manifold from a 20 valve 156 or 166 which dont have the swirl valves and then sell on your faulty manifold spares or repair, there is a 20 valve manifold on ebay at the moment for £80.
Make sure you get one from a 20 valve, the more common 10 valve is different and wont fit.

You learn something new every day!

I didn't realise you could fit a standard 20v intake. I'll look into it.

Thanks for the info, thats great!
