i did a cold compression test which came out as below...
Cy 1 - 125psi
Cy 2 - 125psi
Cy 3 - 126psi
Cy 4 - 125psi
Which is the lower limit but nice and flat across results so i moved on to a cold dry leak down test which came out pretty much 60% leak across all cylinders which is bad!
i couldn't hear specifically where the leak was going but there was nothing in the coolant then i ran out of time.
has anyone come across such symptoms before i open the bloody thing up?
i haven't long got it and not even registered it yet but i just want to drive it but don't want to increase the chances of damage.
