Well I just finished building my b20vtec with JUN3, I finished my breakin period and the engine was running smoothly..
Today I went and tested the car, the car runs hard as hell but then it started hesitating.. I popped the hood and notice the dipstick was popped out and squirted oil.
What is happening? I take it it's too much pressure at high revs, I did not make a pcv system on my block.. and am now regreting it.
Could that be it? I will be doing the pcv mod tomorrow to my engine.. could that solve my problem??
Any input is very appreciated.
tks.

 

If the valvecover breathes to the atmosphere you shouldn't have this problem.

I had the PCV vent clog on my turbo LS/CRX last summer. The engine started smoking badly within a mile, I pulled her over and popped the hood. I went to pull the dipstick and when I touched it it popped out and up a foot and a half into the air, scared the **** out of me, and you could hear the air whistling out the dipstick hole from the pressure still inside the engine. Yanked the clogged PCV line so the engine vented to the atmosphere and she stopped smoking after 15 seconds of idle. Now I vent that **** straight to my exhaust

You must have a nasty NA engine there if you have the combustion pressure to pressurize the crankcase enough to pop out the dipstick. Good luck with it.

 

you might want to upgrade your pcv with a breather kit like the one from endyne. Sounds like you are receiving a lot of possitive pressure from blowby.

 

well I don't have a pcv on my b20 block, I never did the whole drilling thing on it.. so I guess that is what is happening. How did you reroute that to the exhaust???

Tks.

 

it needs to be routed to the intake manifold, behind the b20 there's a black chamber (oil catch can) on top of it is a small hole that's were the pcv goes to then its routed to the intake manifold. You might want to use the vacum route thats under the hood of your car there should be a diagram that displays the vacum route. Positive Crankcase Ventilation (PCV) goes to the intake manifold. have fun!

 

yes on a b20.. with a vtec head I think you need to drill on the block... and put a nipple.

 

go with the endyn kit, works really well for apps like this, no drilling required. Kinda pricey though.

 

back up.

i was having this issue at the track. normal driving is no problem, but when driving 10/10 on track and shifting at 9K the dipstick would pop out. my short term solution for the weekend was a spring to hold it in place which worked. my long term solution is an endyn kit, which im in the process of installing now.

My question is, should i be concerned that this is happening on my 12.5:1 compression C5 motor. back when tolerances were tight 30K miles ago, it would go to 10K without blowing anything out. I just assume the wear and tear on the rings will allow this to happen. I'm going perform a comp and leakdown once i get the trans back on and this breather kit hooked up. If all is well should i be overly concerned?
