My car (EVO7) did pulls out the oil stick (for measure the oil level..)
What can be the cause of it?
Thanks for any help.

Mario.

 

Are you saying the oil dip stick blew out? That means there is too much crankcase pressure. If you're running a catch can, make sure you have it hooked up correctly, and routed back into the intake system.

Buschur Racing sells a retaining spring to fix this problem as well.

 

Put a spring on it.

I got my spring from Autozone, never had the issue, never will.

 

The spring deal is the most ghetto thing I've seen, not to mention you have to fiddle with it.. Buy one size thicker o-rings for the dip stick, that'll keep it in place.

 

^ Umm ghetto? Ok. I don't have to fiddle. It's either on or off? No adjusting. If you don't like it then keep it to yourself.

 

A spring to hold the dipstick is just a Band-Aid for the underlying problem. You obviously have too much pressure in the crankcase which is a bad thing. I'd recommend a few things.

1. A new dipstick since your rubber seal has probably gotten hard.
2. A crankcase vacuum system: http://www.maperformance.com/map-cra...acuum-kit.html
3. Verify you don't have any blockage in your valve cover breather hose not not allowing pressure to escape.

Its possible your pistons rings aren't sealing properly or they're worn and are allowing excess blow-by. One advantage of those crankcase vents I linked to is improved piston ring sealing. This was incredibly noticable on my S2000 where I went from consuming 1 quart of oil every 2k miles (this is considered to be normal for the F20C engine) to consuming none between 5k mile oil change intervals after installing the vents.

 

^ PCV valve from MAP looks like the ticket for the cure.

 

so your saying Buschur isnt smart enough to fix it, they just patch it up with a spring? Your an idiot, my ca has a catch can, set-up properly, new valve cover with NO blockages, and a new built motor and it still blew the dip-stick out when i forgot to put the spring on. the spring is one of the best fixes for the problem without dumping unnecessary money at it.

 

The product makes sense for how the PcV system works, and is known to work. The spring is "cheaper". Looks like another Buschur fanatic. You guys are everywhere

 

^ Lol

 

Has anyone installed these on an Evo? Do they replace the current PCV valves or go in-line w/ the current valve?

 

I just installed mine yesterday (Map Crankcase vent) Car actually driving a little cleaner. I didn't remove anything just added to the existing connections. Install for the manifold side was a bidatch and required me to remove the upper strut due to my gorilla hands lol

 

So what exactly does it do.

 

Keeps boost from being lost and entering the pcv system. And only allows a vacuum from the pcv. Supposedly better mileage, throttle response and power. I did notice the difference and I can pretty much feel anything major in my car...power loss /increase, timing being pulled etc...
