I noticed that after ran @ the track the other night that my dipstick had been pushed out of the tube. Anyone had this happen before w/ out a ring being bad or should I expect the worst. Also does removing the PCV system and going to breathers/catchcans help this issue?

 

Anyone?

 

Had a friends car do the same thing...he fried a cylinder ....his motor is now getting rebuilt

 

Do a search... I know I have read it on here before but I cant remember were.

 

Sounds like to much Oi. More than 1/2 Litre

 

Sounds like blowby...EXCESSIVE BLOWBY. You've likely cracked a ringland... A leak down test could determine which cylinder is possibly the culprit.

 

The blowby is pressurising the sump, try a leak down test to see where the damage is at (i.e. which cylinder is bad). I have seen a blown LS1 shoot the dip stick out like an arrow on the dyno not a nice sight....

 

Does the dipstick blowing out guarentee that one of my cylinders is bad or is there possibility that it's something less dramatic?

 

no , you're building more crankcase pressure than the pcv valve can handle

 

you need to do a leak down comp. test

 

are you running N2O or a blower?

My vortec 350 blew the dipstick out on a 150 shot

of course it ate a couple pistons during the same race.
