Agreed... no dipstick tie-downs could help my bad rings. Bummer.

Check your PCV to see that it is sealing under boost conditions, do a compression test, and look over your valve cover and the hoses going from the valve cover breather.

Securing the dipstick like that is just a bandaid and not good for your car.

good to know thanks.

Great info. I crimped my tube a tad, so it was tighter, becuase the rubber worn down over the years : ( stupid blow by.

PsychoticDead · 11-11-2006, 07:03 PM

Well, I just recently got my 91 TSI Eagle running and an old problem that the past owner had came up...after driving just a few minutes, the oil dipstick will pop up and shoot oil out all over the engine...is there a crankcase breather or something that will get rid of the pressure in the oil pan that could be clogged? I really need some help on this one as I want to get this going tonight...

I got this info from the VFAQ website.. Check it out... its helped me out ALOT.. www.vfaq.com

Dipstick popping out - happens due to crankcase pressure pushing the dipstick up:

A good running motor will blow out a dip stick with a shriveled hard rubber seal
A dead motor (lots of blow by, busted pistons) will blow out a good dipstick
A 1/2 dead motor will blow out a 1/2 dead dip stick
Depending on the actual cause and the severity, the fixes can be:
A spring/wire to hold the dipstick down
Pinch the tube at the top a bit
Get a new dipstick
A full engine rebuild or new pistons
If it blows out under boost with a glowing red turbo and manifold, it makes a nice engine fire. If it happens even once, figure out the cause and fix it.

replace pcv valve.

jredgo1234 · 11-11-2006, 07:22 PM

yes dsm's features a pcv system that sucks clean air (from the intake) into the valve cover, and pushes blowby gasses out through the pcv valve, and into the intake manifold where they are burned by the engine. This only happens when the intake manifold is under vacume (idle. cruising, deceleration).

Check your valve cover to see if it has been removed on your car. There should be a nipple on the left side of the valve cover when looking at your engine from the font. A hose should run from this to your intake (or be filtered somehow). Now look at the top left corner of the valve cover. There should be a metal piece (pcv valve) that screws into the cover with a hose running to intake manifold. Often this system is removed or modified because it leave a film of oil inside your intercooler pipes, intercooler, intake, ect.

If the whole system is intact, remove the pcv valve and shake it. You should hear a rattling from inside it. It is a 1 way valve. If it doesn't rattle it is clogged and should be replaced.

PsychoticDead · 11-12-2006, 12:36 PM

alright, well the pcv is fine so i clamped the dipstick down. now it will spit just a little bit out from under the filler cap...

and does anybody have a complete wiring harness for this car, this oe is a joke...there are so many hacks and crap going on under the hood. i think this may be a cause of my car not running very good at all. the check engine light comes on after a couple minutes of running it...the import car thing is really kickin my @$$!!

and what would driving the car without the thermostat do? it wasnt in there when i got the car? never made a difference when it ran i guess.

jredgo1234 · 11-12-2006, 03:56 PM

If it was me i would replace the pcv valve anyways.

Having oil come out from the filler cap is bad. There is way to much pressure in the crankcase and valve cover. I would concentrate on finding the problem of this.

Go to the local junkyard for a wiring harness and a thermostat.

sag1441 · 11-12-2006, 05:26 PM

go to the dealer and buy a new dipstick also, maybe like 12 dollars. an old dipstick may shoot out becuase the rubber at the top of the stick is old cracked and shrunken

ChiGGz · 11-23-2006, 10:37 AM

I must be getting some sort of unrelieved crank pressure.

I regularly check my oil levels (weekly) and i find after a drive, not even in boost the dipstick would be unreadable cause the oil has gone up lass than an inch past the high mark. You can see plainly that it's splatter and not the oil level rising. Letting it settle for like 15 mins solves that.

The car has no PCV valve atm (no criticism unless it's affecting my situation.)
both valve ports are routed to a oil filter / catch can. So why isn't the crank pressure being removed?

xveganxcowboyx · 11-23-2006, 10:57 AM

What happens after the catch can. Having a vacuum source on the end would be helpful.

Hows your compression?

ChiGGz · 11-23-2006, 11:29 AM

After the catch can it dumps onto the floor..only when I release it though. Otherwise it vents through the oil filter.

I do want to go back to the orig PCV setup since I'm tired of the stench from the oil filter being released into the car.

Will do compression test this weekend.. Will my current PCV setup have any effect on a compression test?

xveganxcowboyx · 11-23-2006, 11:53 AM

It shouldn't.

I would buy a new PCV at the dealer and put it back in.

The other line can be left as is, though routing back to the intake tube after the catch can is a good idea.

From what I think though, the PCV doesn't contribute to my pressure does it? If there's excess pressure it will blow out.

95-talontsi · 11-23-2006, 12:05 PM

Maybe I dont understand what your saying, but from the sounds of it your driving your car then pulling the dipstick out and checking the oil level with out wiping the oil off and putting it back in to check it? oil moves around when you drive its going to move up on the dipstick this has nothing to do with crankcase pressure.

This is also true. Pulling it straight out after driving won't give you an accurate reading. You should just be happy you're not popping the dipstick straight out like the rest of us

Not having the PCV eliminates one possibility for adding pressure to the head, but it also mucks up the system to alleviate pressure when it's there. I'd do a search. This has all been discussed many times. The general concensus seems to be that a street driven car should keep the PCV setup stock. If anything just add a catch can between the two (tight clearance...).

Your sorta on the right track and probably right as well.
I drive my car, turn it off, check the dipstick, obviously splatter right? I wipe it off, and instantly check again, still splatter all over the stick probably cause oil has made its way through the dipstick tube??. It's never blown out yet though.

95-talontsi · 11-23-2006, 02:57 PM

How much oil do you put in your motor? What weight of oil are you using? A heavier oil will take a little more time to run back out from the dipstick obviously.

I work at a lube shop and am checking oil on all kinds of different cars all day, some cars it will have the splatter your talking about but its no big deal.

Also if your not blowing your dipstick out, I doubt you have any crank case pressure problems.

92redtsi · 06-19-2007, 02:15 PM

Well I replaced my pcv valve and put a fram g2 fuel filter on my valve cover breather hose. I then took it for a drive and I was doing a 3rd gear pull and could smell oil so i pulled over and popped the hood to see my dipstick had popped up and blown oil all over the engine bay. The rubber on the dipstick is pretty hard and it doesnt feel like it seals very well. This has never happened before so i was thinking maybe the pcv valve i bought is bad or something? Any and all help is greatly appreciated

kahl23 · 06-19-2007, 02:19 PM

Yeah, it's a pretty common problem. You can try crimping the dipstick tube a bit or buying a new dipstick, but it probably won't help. I ended up just wiring it shut. Put a small worm hose clamp just below the top of the tube. Then take a zip tie and run it through the dip stick handle. Wrap it around the thick part of the hose clamp and tighten. You don't want to go super tight because if you get the right tension, it will hold the dipstick on and when you want to check the oil, you can flick the ziptie off the clamp, then put it back on when you're done.
