okay, my car began to tick over on 3 cylinders for some reason,, ive changed plugs/leads,, theres a deffo spark on the cylinder that is down....
but when i rev it, it freely revs up on 4..

put on the compression tester just now to check it,,

tested the cylinders and cylinders 1,2,3are showing 140psi,, where as cylinder 4 is down at 80 psi!!!!!! now the car is testing my paitience!

it is a freshly rebuilt engine 1300miles ago,, everything new, low comp forged pistons ect!!!

hopefully it may be the head gasket but aint using oil or water!!!

or a dodgy valve, lifter or rocker..

i have a spare std head but now thinking of stage 3 head,.

my luck!!!


also changed lifters and rockers, hoping i wouldnt need the head off...lol

and still the same!!
