well a little update but more to come with a bit of data im sure.
just picked up my car after a big service, ive been putting the cambelt off for a bit too long.
due to the labour costs I decided to get a spare inlet manifold(newer version) and remove the swirl flaps and install the aluminium blanks off ebay.
I can always clean up and plug old manifold and sell on.
the swirl flaps in the newer manifold are one piece with no screws so required drifting out, cleaned up, glue applied and using a c clamp pressed into the holes, they were worryingly tight but went in , I bet the glue is belt and braces.
anyway thanks to Alitalia Wrexham for the fitting as part of a cambelt water pump thermostat and egr cooler removal(as egr removed anyway)
now the bad news
even though being done with the cambelt kit etc howard said it was a long job as there was a bracket in the way between manifold and high pressure pump that needed to be removed to get the manifold off.
so not a quick and easy job to get off and on.
so as it is now im now running a manifold with no swirl flaps with the actuator still connected to the loom(hanging on strut brace next to egr plug)
I will feed back more info when back in work Tuesday as that will be best to compare to normal work journey. so far from picking it up and driving home im struggling to notice any downside.
ill put up a you tube link after to the play in my original swirl flaps and some pics.
