Rb20det (dip Stick Pops Out ) Why?

[migs]

hey guys i have a problem just and need some help,

i have an RB20det in my car

its running on 12psi and has some minor mods on it

i realized when i run the car hard

the dipstick pups out of the housing and oil spills on the engine bay and block

also there is oil in my intercooler piping

what can this problem be ?

[kwickr33]

too much blow by or blocked breather hoses. Its normally a bad sign.

[migs]

what do you mean by too much blow by?

[hypergear]

too much crank case pressure I guess. normally happens when rings are tired.

[DanShirts]

+1 bad rings

Do a compression test, you will have low compression on at least one cylinder.

Or just zip tie your dip stick down.

Have you got a catch can? Is it hooked up incorrectly?

[EdGTR]

The other thing to check is how tight the dip stick is in the hole. its getting old now and the rubber section might be a bit hard. I had the same issue on my gtr, got all worried did comp tests and leak down the whole lot then bought a new dip stick and it never happened again. I was happy!!

we dont have a catch can

and we turned the boost down to 10psi and ran the car the dip stick stayed in

If you can, try and get a dipstick from a R33/R34, i believe it has a spring on it to keep it locked in the dipstick hole.

what about the oil running through my intercooler piping all the way into my TB?

Nope that's for the auto trans.

The R34 has a plain dipstick.

what about the oil running through my intercooler piping all the way into my TB?

Could be numerous things

[DriftSquad]

turbo seals worn?

[migs]

The oil is running from the breather line that runs from the valve cover to the turbo inlet pipe

and going into the turbo and reaching up to the tb

[r33_racer]

Easy. Disconnect that line to the intake. Run it into a breather can.

Then clean out the intercooler and all pipe work that has oil in it.

could also be failing pcv valve .

Run a catch can, should fix the oil problem, that pipe is hooked up to your intake pipe and not your cooler pipe right?

[migs]

yea the intake pipe

[bubba]

could also be failing pcv valve .

I did suggest that, migs sent me a photo of his engine bay and all the breather hoses are plumbed up correctly. If it isn't the PCV valve then I'm leaning towards dying rings..

A catch can won't FIX the problem, it's just a bandaid. It will just stop oil from accumulating throughout the intake piping and it will also prevent the detonation that might start happening as the oil in the intake stream lowers the RON of the fuel.
