Rb20det (dip Stick Pops Out ) Why?

[simpletool]

Tired rings aka blow-by. All signs point to this. Check compression.

ie. Pressure from combustion chamber is leaking into the sump, this is forcing too much oil up into the cam covers and out the breather pipes into your intercooler pipes.

I've had this problem done a compression test and 3 & 5 rings were fried. So this caused the dipstick too blow out and spit oil everywhere. Looked like it had a nose bleed went all down my front bar. But also had a catch can incorrectly hooked up too thin breather hose running too it. Bought it all like this never again will I go for the cheapest skyline I can find got ripped hard

i had the same problem in my GTR

they just put a new dipstick in and crimped the end a bit so its tighter

havent seemed to have any problems since
