Angry Can Anyone Please Help My Wrx ? :(

Hi all!

When my car was mapped last week , a misfire began on cylinder 4, so wasnt able to finish getting it mapped, so i mauld the car home.... was advised that prob plugs or coil at fault..

Fitted new plugs, NGk pfb7's... and also got hold of a newish low milage coil pack, fittted the plugs first and misfire is a lot better,tho noticed a flat spot between 2-3000 rpm, like the car holds back and jerks when this happens on the rd. Fitted the new coil to cyl 4 today and was all good, plugged my mates VAG com in and checked faults, cyl 4 misfire... erased and didnt come back on, engine runs smooth... winners... so i thought........

driving on the dual carridgeway and gave it a bit ( as you do) engine light came on again, while was at traffic lights car was jerking alot, assuming it was missing again.. grrr, also this flat spot returned, tho when press the throttle say half way down through the gears it drives fine!

going to plug it in tomorrow again....... see what faults are there..

any ideas or help people getting a bit stuck now with things to try, going for compression check nxt tho engine is silent, not using oil or any water.......

HELP!

cyl 1 =120psi
cyl 2=70psi
cyl3=155psi
cyl 4=65psi

Thats not right! Suspecting blown head gasket between cyl 2 & 4 Doh!

Engine out this weekend me thinks and inspect the damage...

anyone no if the air con pump comes off with out needing to be disconnected?

Arrrrrrrrrrrrrrrrrrrrrrrrrgghhhhh! CARS!

any tips on removing engine? job for sat , is a hoist needed or can i get away with jacks????? engine out from top or bottom?

this is most prob headgasket i recon as both cylinders low compression........

cheapest place get parts from??? think metal head gaskets is best bet... stronger anyway

no you need to drain a/com pump if your removing it or just leave it attached and monover the engine round it , i belive the engine come's up otherwise you need to remove the sub frame ect easier to go up

can also damage the crank bearings, which can cause failure down the line

although if it doesn't go pop within a few weeks after new headgasket you may have gotten away with it
