7745 turbo Engine head oil leak on #1 & #4 head at exhaust port outlet ??

[turbo_7745]

Hi I have 7745 turbo with an oil leak from the exhaust port 1 & 4, there is no blow out at the dipstick but some blow from the breather pipe, it is using some oil. It still has plenty of power to pull a 6 tonne load or 8 foot mower.. Would it be enough to rebuild the 2 leaking head pots or would it need liners and pistons

Hi

Just tighten the manifold bolts and forget about it.

Unburnt oil in the exhaust means the exhaust valve guides leak a little. If pistons leaked oil to the top it would burn blue.
