Dipstick Popping Out!

[markk]

I've just completed some mild mods to my GTR...

* New turbos (Garrett 2860R)

* New intercooler (600x300x115)

* New split dump pipes

* 3" exhaust

* New excedy clutch

The problem is that when the car comes on boost, the dipstick pops out and some oil spills out. As far as i know this is caused by blowby. Does this mean my motor is on the way out ? I did a comp test and all cylinders were around the 160 mark. I think cylinder 2 was down to about 150...

I'm still yet to take the car for a dyno, and as far as i know the car is running standard boost.

Any ideas what the problem may be??

Thanks

Doesnt sound good - Pressure build up in the bottom end?

NOOOO!!!

Does that mean the engine is looking like it needs a rebuild?

Possibly - I would consult a reputable workshop before jumping to any conclusions though

I haven't got any catch cans fitted. Thats what I was going to do to stop the dipstick from popping out.

Where is the PCV valve? I suppose I can take a look at that..

the drivers side rocker cover breather pipe goes to it.

I'll take a look.

Thanks for your help everyone !!

Is there anything else that i can check other than PCV valve?

Get a leak-down test.

Get a leak-down test.

Yeah that was going to be the next step when i get all other factors ruled out.

Mine popped out once, I cleaned the oil off the rubber stopper and inside the top of the tube with a bit of rag, hasnt popped out since. I will have my fingers crossed its that simple for you too

Not what you want to hear but mine used to pop out when I had broken Piston ring lands.....

It also came up ok in Compression test.

Go the leak down test

I should add that was in an RB30ET not the GTR.

[NewKleer]

my r31 popped out after a suspected overfllling of the oil on oil change. could be blowby in the old engine though

[CruiseLiner]

sounds like a ringland is broken and as said above it shows its good with a comp test, but a leakdown will show you the true reading.

hope its something simple, as its an expensive process rebuilding

Had the same problem in my GTR all it was, was the seal on the dipstick was stuffed. $30 from Nissan for a new one and its as good as gold. Try getting a new dipstick first.

[Zardos]

I too had the same problem and found it was the seal on my dip stick as well. I just wrap a small pice of electric tape around the seal and that solved my problem.

Yeah mine used to do that also and i know the motors o.k. The dipstick was loose so i put a small spring on it !. Probobly should just buy a new one as its a pain to check oil level now !
