hey guys just wondering what would cause ur dipstick to blow out about 150mm?? this has happend twice now.........??

too much crankase pressure. are ur breathers blocked? check that

Is this a turbo vl ? also do you have a catch can? maybe you have plumbed it up wrong

the last time this happened to me i lost my compression in the last cylender for some odd reason but this was with a rb25det in a 33 tryline....but yea droped compression bad.....sounded like a rexy

More details on the engine and setup please.

or the engine is breathing = bad. But yeah, I'd try going some bigger breathers with a catchcan that vents to atmo through a filter.

Sory guys yer vlturbo rb30et standard prety much 9psi no catchcan

For whatever reason your crank case/sump is being pressurised. Worn rings, busted ring lands, holes in pistons, poor rocker cover breather etc etc. First check to make sure the breathers off the rocker covers are functional and not blocked up with crap. If thats not the case you can try increasing the amount of breathing ability you have but it will only be a band aid measure. If you blowing the dipstick out 25cm thats not good.

i had the same problem....got fatter hoses and a bigger filter on the catchcan and that fixed the problem.

i had the same problem, i hooked up a spring from the dipstick to the block, that seemed to fix it.
