Hi I'm Wayne

I will help you with this

Merry Christmas

I have rebuilt engines for 34+ years

the only thing that will cause that is wrong head gasket

or not seated proper, or liner too high

I hope this helped you

Ok so last year the head gasket was seaping so i removed head and toom to my engine builder and he completely remaned the head new valves and seals and rockers the whole works. Checked for trueness and fine he came out and inspected liners and fine i then reinstalled head and hooked everything up since then I have had lots of oil dripping out of blow by tube for the last year truck runs and performs properly

Ice been told that some engines have a screen in the blow by tube and that mine may have fell out or something when it was put together.

Thank you for that

most engines have a screen in the breather tube

in the valve cover or the block, if it fell out , that would not cause oil

to come out over board breather

are you getting any puffing from dip stick tube , at idle

I hope this helped you

Customer: replied 11 months ago.
I get a steady steam the come out of the dip stick tube but it is consistant not puffing. Its the same stream that comes out of the blow by tube but it not its excsive like needing a inframe it just leaks a drip of oil out of the tube every 20-30 seconds doesnt when cold, only once it get warm it seems, the blow by tube is valve cover mounted
