    Thanks for that, just thought I would double check.

    Another question now!!!

    The car start and runs fine now.
    Untill I try and start it when it's warm. It refuses to start whilst the car is still hot.
    Any ideas? Hope it turns out to be something simple!

    Cheers

    does it crank over ok? my guess would be failing ecu temp sensor, but check for a spark and all the usual stuff first

    check that all the wiring to the alternator is good. If its looking a little old I would change for new and make sure everything is connected up as it should be. If the battery still goes flat after your initial checks then it could be the alt.

    ^ what he said, also check the voltage at the battery with the engine running (idle and fast) to check the alt is actually charging the battery.

    If not, double check your ignition timing, I've had symptoms before of flat battery every morning and it was the dizzy being far too retarded(?) iirc.

    Thanks for that, Just to confirm, Its hunting but there is no air leaks from anywhere, would the next logical step be a isv? Oh it's also had a new blue temp sensor, plug and wiring because it was running rough.

    Thanks for any help

    could be the idle switch or wiring to it? should hear idle switch click just as throttle closes, and check wires to the throttle switch plug on the back of the tb. to test wiring and ecu hold throttle just open to about 1500 rpm then press the wot switch on top, revs should fall then rise again when you release.

    Right got the thing idling okay, but last night after i came home i noticed it had poured its oil out from the oil filter, now i know this usually means piston rings? but its not smoking or anything, could this be caused by a blocked breather pipe? and also on the front of the agg block there a housing and pipe that go to the mk3 rocker cover, i have made a pipe to go on out of mk3 and mk3 pipes from when i first did the conversion, does this need to be block off?

    thanks in advance

    could just be a seal has gone in the filter, or its actually coming from one of the pressure switches so check the boots arnt full of oil. also a symptom of a failed pressure relief valve in the oil pump as it makes oil pressure too high. if it was rings id expect it to smoke a lot.

    nothing wrong with plumbing in the breather properly, in fact its recommended rather than blanking off as they can breathe a bit too heavy for just the rocker cover breather

    Yeah its actually blowing the pip out through were you screw the oil filter on, so there's definatly to much pressure somewhere I'd say
