URGENT info please - car stranded (2.0 Petrol Turbo)

[jasper5]

I'm not familiar with your engine type, but can you see the camshaft with the oil filler off? If not you will have to take out some bolts on the cover and move it back a little to view the cambelt.If you aren't sure turn the key and see if the cam turns.

Ill double check but I think not as the filler (if i remember correctly) doesnt pour directly onto the valvetrain but into a different pipe that leads to the bottom of the engine - but thats from memory at best.

Thanks for the tip tho - will try it if its near the valvetrain.

Ok,

Went there this morning. After some checking - managed to get teh cam cover loose enough to see the cam shaft turning - not the belt.

Then found when I took a plug out - no spark. Found a fuse at location 1A blown, replaced, got spark.

Car turned over, fired once - or tried to and no go.

Found the intake rubber that goes from the airbox to the top pipe over the engine split - patched up as best I could - no go.

Then took the oil cap off - milky white - suspected blown head gasket.

That could just be condensation. Are you able to compression test it?

I dont have any means to test with. Something still sounds wrong - ill try and post a vid later. Problem is car is stranded at Asdas - difficult to tow it home in these conditions - so not sure yet.

I may spend £18.99 on a Halfords one if its worth it? Any idea what kinda of reading I should get across each cylinder?

OOoh, can't remember off the top of me 'ed. Haynes says below 10 is a bad sign and a difference of more than 2 bars between cylinders is also a bad sign. Maybe it dropped a valve A compression test will tell you if you need to have the head off or look elsewhere I suppose.

Thanks for the info.

Not sure if this will work - please ignore the diesel engine sound at the start and end - thats my 407 idling next to the 406.

Damn, Youtoob title is wrong - 406! not 407.

chaz you could ask here as well www.407owners.com it might help with your 406 and your 407

Sorry Chaz, but that sounds like a classic no compression sound.

You may have bent valves or something, possibly cam belt teeth stripped/belt slipped, or a possible head gasket fault.A compression test is vital, if you haven't got a compression tester you just need something to push into the spark plug hole and see if it will get blown back with engine compression, but I'm fairly certain that you have zero compression.

Thanks - thought as much - any of the above which can be fixed but not sure the car has any value at this stage.

I suspect Ill probably get more for the car as bits - it has all the exec things and leather etc.

Thanks - the 407 is OK - touch wood. The 406 on the other hand .... well ....

I agree with Jasper, your cambelt has definitely gone, there is no compression from listening to that video, valves will be damaged, the camshaft might also be cracked (you need to remove the camshaft to check this), if you dont think its worth doing all this work, dont bother going any further or spending money on compression testers or anything else, put it on ebay and sell it as it is with a 99p start or break it for spares

Something odd - struggling to get the bits off but thus far no evidence of anything suspect related to the camshaft. Oil is dark, nothing that indicates headgasket issues. I cant get the damn top cambelt cover off - ive loosened the 2 bolts - it pulls and up down but how to get it off?

How would I know if it timing might have jumped? If I can get a cylinder to TDC, what position will the cam be in?

Also - and this is the only thing found thus far - the metal pipe that goes between the intercooler and the turbo has oil in it - a fair bit too. Blown turbo?
