It's your Crank Sensor lead Griff, the actual sensor can't be seen because it's hidden behind the Power Steering Pump Thumbs Up!

right all back together

and car started first time !!!

need to get some fresh oil as ive just put some real cheap oil in to hopefully flush the rest of the shit out !!!!

when first started it sounded very ruff but after a min or so it sounded back to normal

well apart from the loud ness of the exhaust as need to get under the car to tighten the front pipe to the manifold correctly (split it so i could weld the small crack in the exhaust manifold

)

then after 10mins the dreaded orange light came on Sad

did a opcom test and it came up with running rich !!
not to much of a prob

at least it proved it was the head gasket that had gone as now no misfire on pot 3 (where the leak looked like it was)and now all the steam from the exhaust has also stopped

also now the top rad pipe is not getting solid like its going to split lol

but !!!!!!! asoon as i ran her the over heat light came on again!!! Sad

then dropped then came on again and keeps doing this!!!!!! could it be a knackered sensor????
when it starts getting hot the fan cuts in now as well which it never used to,on the wirer that goes to the temp sensor(think it is anyway)its a single wirer there is some of the wirer showing,could this be earthing out and coursing this????
next thing is i still have no heating either!!!!! maybe air lock??????if so how do i get rid of it??????
all pipes seem to get warm apart from the bottom pipe coming from the heater matrix!!! which inturn leads to the lower rad pipe which again does not seem to be warm Sad

im so nearly at the fixed part so i can finely start to enjoy the omega,so please help me sort this bit

RIGHT NOW IM GETTING REALY P>>>ED OFF WITH THE CAR!!! Cry

i loved my old omega but this new one is realy starting to test my love for the omega!

right as u all no ive done the hg,but seem to have a majour prob with a air lock or something,heres what ive been doing today

1. ive flushed the coolant six times!!! no more or the old blue coolant,ensured 3 times only clear water came back out! ran it each time antill the fan cut in (to ensure the thermostate had opened and the water in the block was moving throw,also had the fans on full) so now i have lovely clean 50/50 orange coolant in the system:-)

BUT STILL NO F.........g heating!!!!!!!!!!!!
i had changed the hbv but i must admit it was a cheap one from ebay Sad

,maybe thats no good??? to put my mind at rest could i just take the hbv out for now and just run the pipe from the back of the engine and run it straight to the inlet of the heater??? surly that would give me heat?and at same time prove if or not that the hbv is either working or not???????

also Sad

the temp gauge!!!! not sure how to test but i think thats got problems!!!! keeps showing engine is very hot !!! sometimes when all the pipes/rad etc are only luke warm!!! BUT then when you press the brake pedal it drops down to where u would think it should be,the fan kicks in around 90ish when the gauge seems to be working fine but when it just shoots up when the pipes are still cool it does not!!!!

seeing it drops again when the brakes are pressed could it be a EARTH PROBLEM??????? would this course this???would i be best to change the sensor?(i assume the gauge is the open at back of the block with only one conector on it?)

also comes up with error code saying running lean! now i no the front pipe is leaking where it meets the manifold and also where the pipe conects to the next pipe ,seeing theres 2 cats in that section ,if theres a leak could that caurse the ecu to think its running lean????/

cheers for everyones help with this,im so close but so far

Remove vac pipe from top of HBV & plug it (small screw?) then run engine up to temp.
Yep, single connector.
What code are you getting

Feb 2011 at 20:02 the opcom just comes up saying running lean as for the hbv so if i just block the pipe off,it will do the same as taking the hbv totaly out of the system???? what do you mean by single connection? cheers griff

Feb 2011 at 20:09 No vac = heat, so in theory remove the vac supply pipe from top of HBV & see what happens. Temp sensor listed on website Z2.2XE from 20Y66444/31040545 12992783 £11.70 £10.54 £8.84 Don`t know whether that`s for the gauge or the ECU though
