we got the cossie looking great she was running 15 psi nicely on our drive to a classic car show yesterday done almost 50 miles but on the way home was popping at banging at only 10psi as soon as trying to load up the car and boost ???? any ideas why would it be ok and then not

Bullett

cossiej

mine was doin this, the nipple on the map sensor had snapped

cossiej

we changed the phase sensor the car revs ok the counter was abit funny but seems better since changed ..... map ok only a few months old the top of number one piston is wet and plug black as black

This and the popping noice really sounds as a bad connecting in one of the 3 connectors at the bulkboard to me..

cossiej

thanks wim will have a look at them to nite waht bout the spark plugs etc ??

Bullett

iTrader: (2)

jay you have checke dthe dizzy havent you?if one of the terminals is fooked inside it may cause an issue. but i still say those plugs may be broken down inside.

cossiej

i have neil we did the phase sensor as wires were broke but will check again does yours still run amal valve ???

PeterLucas

Not boosting, siezed waste gate? ive had that but mine had seized shut and boost went through the roof!

cossiej

no had the turbo of it was fine all day saturday its just the black and wet on top of no 1 piston that worries me ????

PeterLucas

Poping noise might be unburnt fuel getting through to exhaust (hence wet no.1 not firing) have you tried obvious plugs & leads?

Had the plug out to see if any spark?

Crankshaft sensor gap can royally fook things up as well!

PeterLucas

Also a compression check wouldnt hurt, burnt out exhaust valve would cause noise/poping through exhaust manifold.

cossiej

leads new plugs new got a strong spark plug just very black what should the phase sensor gap be ???? oh comp ok

cossiej

ooops sorry meant crank sensor cap

jay my escort runs air injectors so no.i may have a amal valve some where but i think i sold it

PeterLucas

Phase sensor is 0.2mm - 0.3mm.
Crank shaft sensor is 0.6mm - 1.0mm

Check you have the phase sensor wires the correct way round, that one got me!

PeterLucas

Swap injectors see if the problem moves to the swapped piston, then you could isolate it to wiring or injector? Just a thought.

cut the connectors out and solder theses are a pain in the ass

They can cause all sorts of funny probs

cossiej

guys thank you so much only thing havent done is the connectors and the injectors just got in after being in the garage will give her a run tommorow fingers crossed

We learnt that one rather quickly when first fitted it, made an awesome bang on firing her up for the first time

Jas checked the gap last night (as I'd mentioned Sunday - it'd done a few miles so could've 'moved' - especially given who fitted it ) the gap was quite big and *fingers crossed* she was running well last night (I almost gained my first 3 points )
