Crankshaft rear main seal leak after increasing fuel.

[0Hoon]

I've put the factory boost up to 16psi from 11psi on my humble TD42T with HT18 turbo and engine oil started leaking from bellhousing (definitely not sump).

I think the boost might have increased the blow by somehow and pressurised the block. Anyone experienced this?
Engine done 320kms so it might be just coincidence along with already worn out rms due for service though.

Thanks

If your block is pressurized you have a big problem
I'd be making sure the crank case vent is free first..
Comes out at the back of the rocker cover..
