How many miles are on the engine since the rebuild?

1 - The squealing could be the cambelt tension is too tight
2 - If it hasn't done many miles it could be that the tappets haven't filled up with oil properly.
3 - Try cleaning the map sensor with carb cleaner, and the icv too.

I have the dodgy idle problem with my engine, and sometimes the revs drop when I press the throttle. And it stalls every now and then.

Has the gearbox been changed because it might be a locating dowel that was forgotten to be put back into the new gearbox for the starter motor. That noise sounds familiar.

Cheers Gents,

Haven't checked the dowel yet, I think I remember seeing it but I may be suffering some kind of delusion having played with french car parts for too long! Have had boost pipework off and checked it all, also tried spraying easy start around whilst running with no effect, replaced ICV which helped a little but it still doesn't always idle, changed crank sensor for a known good one as well and tried unplugging PAS sensor. Cleaned MAP up but will get it on diagnostic machine before I shell out for another new one :S

So currently it doesn't like starting, when cold it will not idle but as soon as it has been running a few minutes it behaves pretty well. And the engine still sounds a little unhealthy IMO as it has a rebuilt head, good bottom end, new cambelt, all tensioners & pulleys, waterpump and new head gasket I know they are not the most refined engines in the world but it seems a tad excessive. I'm taking to Lynx this week to see what Mr Walker makes of it and if he finds nothing perhaps fire is the answer!

Definatly think you should checked the locating dowel on the starter motor, only a few bolts. That noise is really famililar the more i listen to it. With that missing mine tried cutting out a lot too, I think the starter gets jammed of which stalls the car as mine wanted to cut out too.

Worth a 5 minute check.

Really confusing. Dodging ground on the gearbox? These can cause odds and troublesome starts.
