Blow inlet manifold gasket!!

[FRV85]

Hi,

Help please!

Could a blown inlet manifold gasket give low compression readings across all six cylinders?

I know the inlet manifold is leaking oil which I believe was from when the fuel was up to high and I was getting excessive blow by.

I installed a catch can just before I had it tuned for the second time by another specialist.

Compression test numbers are:
1/300psi 2/280psi 3/280psi 4/240psi 5/280psi 6/220psi

I have asked a similar question in another post but this question is specific to the inlet manifold.

Cheers

Blown inlet manifold cannot give low compression number. Head gasket/valves are possible, but cylinder/ring wear is most likely if its across all cylinders
