Just gone efi and got it running today. Didnt do 3-4miles on road test and when I got back the oil cap was off and there was a mess there and over on the breather side I have the standard breather with a pipe and micro filter on the end of it and oil had sprayed out that too

Now my first thoughts are piston rings are away but the engine and bay were dry in the frst donor car. Sort of hoping I never put the oil cap on right and cos that came of it caused the oil to blow through the breather system??

Any ideas?
