help dip stick is poping out

[winkdogydog101]

ok first problem with the dsm! im sure the first of many. Well i finally got the car running pretty decent on just 10lbs its pretty fast and takes my cobalt till 40 to pass it i was blown away. But under hard boost of 10psi my dip stick is poping out. I cleaned the pvc or what ever valve and cleaned the whole head when i took it off for the headgasket and arp studs. Not sure why its coming out any easy fixs for it. When it comes out small sprinkles of oil come out and hit the turbo manifold causing it to smoke like my cars on fire. I checked oil levels and its not shooting out anything really noticeable but i want this fixed.

THANKS FOR YOUR GUYS HELP

Means you have excessive crank pressure not being released. Replace your PCV.

Or, you can just get this.

You could always crimp the dipstick tube to making it have a tight fit to keep it from coming out or you could do it the right way which cost money and that is getting a vented catch can, and that will keep the dipstick from coming out. What i understand is giving alot of us this problem is that compression is getting into the crankcase and the only place for it to go is out the dipstick soo putting a vented catch can will give it a place to release instead of out of your dipstick..

it could be the seal on the dip stick. if so replace dip stick. and if your going to remove your pcv valve you might as well replace it their only 5 bucks

usually caused by blow by or bad pcv sometimes the little rubber part just wears out. Easy fix just squeeze the dip stick tube with a pair of pliers not to hard though just a little at a time til it stays where its supposed to be

And if your pvc valve tests good then you need to do a compression test.

Excess crankcase pressure is the cause of the dipstick popping out. A few reasons why this could be happening.

1. Your rings can be toast which can cause the similar issue you are having. The rings around the piston are not sealing and letting pressure into the crankcase thus blowing your dipstick and oil out.

2. Your PCV is clogged or not responding quickly enough to the pressure being built up from heat in which pressure leaves through your dipstick.

Great article to replacement options for the PCV and how explains how crankcase pressure works and how it affects engine performance.

The dipstick shown above from STM is a BIG no no until you find the problem and fix the issue. Dipstick blowing out is a major cause of engine compartment fires and is extremley dangerous. Most will agree to find why you have excess crankcase pressure before installing a band-aid fix.

thanks i really wanna fix the probelm but ### if it still pops out will it being spring lock hurt the engine if its not venting and thanks i love this ####ing forum so much quick answers and everyones been pretty cool so THANKS ALL

its not the rings ive done a comp test and a leak down test both are perfect so? how bad will this catch can hurt my wallet i guess to intro myself im jewish when it comes to things i dont need to replace right away

The STM dipstick still allows the release of pressure, the spring just keeps it from popping out all the way and making it messy.

At 10 lbs. of boost, I imagine it's his PCV, he said he just got the car running, so I would assume his regular troubleshooting was a compression test. But, yes, it could be bad rings.

change your pcv, or get a catch can (which will vent your crankcase) or buy a $2 long exhaust spring from advance auto parts and m,ake a sprung dipstick.

i bought the spring for my evo when i was running 35psi on my fp red and it fixed the dipstick problem. mind you i had tried everything else first. ive also done the spring od on all 4 of my dsm's. good luck

You need to try and fix it from popping out, without crimping the dipstick tube or clamping it down somehow. There's 3 things that can cause your dipstick to pop out.

1. Bad pcv valve, allowing boost to pass into the valve cover and pressurize the crankcase, blowing the pressure out of the dipstick.

2. A bad turbo oil seal, pressurizing the oil lines and therefore the crankcase as you build boost, relieving the pressure out through the dipstick tube.

3. Bad rings, allowing compression and boost to leak past the pistons and pressurize the crankcase, blowing out the dipstick.


Test the pcv valve by taking it off and blowing into it (in the direction of the valve cover) if you can blow air through it then it's bad.

If it tests good then move on to the compression of the motor, if it's bad then drop a cap of oil in the cylinders then test again, if test improves then you know that the boost is leaking past your rings.

If compression is good then test your turbo: Do a boost leak test on the turbo inlet and put your hand over the valve cover breather tube and feel for air, then move the boost leak tester to the throttle-body elbow and test from there, if no air comes out of the valve cover breather when testing from the throttle-body elbow then you know you have bad turbo seals.


I recommend you do these test in the order I typed out. Also my compression is a little low which was causing my dipstick and oil-cap to blow oil all over the place, I did the following to help relieve pressure, it's just a band-aid but it works quite well for now -

Why buy an oil catch can for 80 bucks when you could make your own? All you need is some welding skills.

 

[winkdogydog101]

can i mig weld one?

Or, you can just get this.

STM - SPRUNG OIL DIPSTICK | 90-99 DSM

Wow $55. That isn't necessary. This is will do.

Or go to any hardware store buy a spring and a clamp for a few dollars and make your own.
