Sr20det dumping oil out dipstick

[lunzee]

Just a question, sr20det, blows out dipstick, oil everywhere, but zero oil in my catch can. No smoke, runs mint, think it's rings or pcv?

[ultimateirving]

Are you sure you have the catch can hooked up right? It sounds like you're pressurizing the crank case. Can you post a picture of your catch can hoses and pcv routing.

[lunzee]

Yes I will post a picture tonight after work, I am unsure of the correct routing, it's my first sr and the previous owner has the car set up very badly, just starting to figure out all the issues, it only pushes the dipstick out at higher then stock boost levels.

[ultimateirving]

Ok since your new to sr, stop boosting it for a couple days til we can help you go thru it and make sure you don't make anything worse.
How long have you had the car? What have you changed since you got it from the po

[lunzee]

Haven't changed anything since I got it last night, car is a track missle so it's not being driven, car needs work, it's got a 20g on 12-14ish psi, no boost controller, no tune, single can mad, stock injectors, front mount. And a cheap catch can. I have no info and will have to take a closer look at it tonight. So I can figure out what I need to order to get it going in the right dorection

[Dboyizmlg]

You are probably over boosting.

Do you have boost gauge installed??
If you do check your gauge.

Manual boost controller of some sort?

[Dboyizmlg]

Dip stick popping out usually the cause is over boosting, causing too much pressure in the crankcase.

Check and confirm boost pressure. Most likely cause is a faulty turbo actuator.

[lunzee]

No controller, ebay waste gate, boost is at 14 psi, no spikes or insane over boosting or anything

[Dboyizmlg]

12psi+ is too much for factory ecu and injectors with that size turbo.

If actuator rod is adjustable try setting it to lower boost, 7psi max!
Also how is the set up on your catch can?

Edit: external wastegate? Swap out to a softer spring for 7psi

[lunzee]

I am aware that the stock ecm, injectors etc is not good for 14 psi. What I'm saying is the cheapo ebay turbo installed by the previous owner has a waste hate that is set at 14 psi so there is nothing I can do at the moment, I'm am not knowledgable enough to tell you know the pcv system and catch can are routed so I will post pictures after I get home from work.

[lunzee]

I am also unaware of how to adjust the actuator rod. I really do not know a lot about this at all, that's why I'm asking for help, I misread your previous post

[lunzee]

Internal wastegate, sorry for the confusion

[Tom N]

It's popping due to high crank case pressure. 14psi on that turbo is not going to cause high enough crank case pressure unless your rings are bad and your getting a bunch of blow by.

Or what this guy said ^

[lunzee]

So where should I start guys?

[Tom N]

So where should I start guys?

Would like to see how you have your crank case breather and pvc set up.
I would do a leak down test.

[lunzee]

Okay I will post a picture of the pcv, and catch can and everything tonight, and as for a leak down test I have never done that, I only know how to do a basic compression test, is it something I can do with rented equipment or is it more involved?

[Tom N]

I don't know if the auto parts stores loan leak down testers. You will have to check. You will need a air compressor. As long as you have that it's very easy to do.

[lunzee]

I cannot seem to find a leakdown tester, will a standard compression tester do? Or will I need to buy one

[Tom N]

You can start with doing a compression test. Put oil in any cylinders that are low then retest and see if compression comes up. If it does you need to do a leak down.

[ultimateirving]

Get pics of the catch can system before worrying about compression test. Takes a lot less time for us to tell you it's hooked up backwards(which in 90% sure based on description)

I agree. Your rings would have to be really bad to be popping out the oil dipstick at such low boost pressure.

[lunzee]

Still waiting to be out of work to get a pictures but it appears to run down the side of the valve cover towards the front of the car, then down to the catch can and the other side of the catch can goes to the intake

[Sileighty_85]

first off thats the wrong dipstick for that engine so you are probably over filling the engine oil.

Either that or you have really bad blow by from worn piston rings

[lunzee]

So that is one idea, getting closer I'll order a dipstick lol

[lunzee]

I order and an overnighting a oem sr20det dipstick, anything else anyone else seeing ran incorrectly or anything please let me know

[Dboyizmlg]

Take pictures of your engine bay

Here's another one

[ultimateirving]

Catch can seems to be ok. Try testing out your pcv, it's the little fitting on the back passenger side of the valve cover. It should only blow one way

[lunzee]

I could be wrong but I think it is very odd that there is this issue, but ZERO oil in my catch can even after beating on the motor

http://i1216.photobucket.com/albums/dd368/lunzee/7F2F8131-BD0C-4FA3-B887-3EAADB9EC562.jpg (http://s1216.photobucket.com/user/lunzee/media/7F2F8131-BD0C-4FA3-B887-3EAADB9EC562.jpg.html)

[lunzee]

Oh and the pcv tests good, pulled it out, blew in it. Tests good, cleaned and reinstalled

[lunzee]

Dipspick will be delivered tonight. Will check oil levels and if that is not the issue, will compression test and go from there

[ultimateirving]

Good to see your testing things. I will check back once you install new dipstick

[lunzee]

Don't beleive the dipstick was the issue, just discover I'm over posting to 20psi with no supporting mods, adjusting actuator as I type

[lunzee]

Backed actuator all the way out now at 14psi

[Dboyizmlg]

Lol, dude put it at least 12psi.

Then check if it still pumps oil out

[lunzee]

It is threaded all the way out and I'm just under 15 will check for oil spills again in the morning

[lunzee]

If anyone knows a way to get the boost lower please let me know

[Dboyizmlg]

Just seen your engine bay pic.

I think you have your boost/vaccum hoses mixed up a bit.
At the throttle body there are two nipples up top.
One for fuel pressure regulator, and the other for boost/vaccum.

The top left nipple (thinner one) should go to the fuels pressure regulator.
Top right (fat one) should be for boost/vaccum source ex: blow of valve.

I notice you have a "T" near the actuator, where do the lines lead?

The actuator needs it's own boost source ONLY! No vaccum here.
Which means, only have it going to boost source (hot pipe preferably) or turbo housing if it has a nipple fitting.

Give us pictures of your vaccum routing

[aaron.nueva]

I had that same problem, do a compression test then a leak down test! For me, my 4th piston was fucked lol. Broken rings & broken ringlands, actually we're just gonna be finishing putting the motor back together today haha

[jr_ss]

If anyone knows a way to get the boost lower please let me know

Most likely that actuator is only good for 14.7 psi or higher. You'll have to buy a new actuator or find an OEM one to make work if you want 7psi.

[lunzee]

I'm going through the vaccum lines now, got it down to 12 psi which is a little better. But noticed it now smokes when you return to idle after spooling

[lunzee]

Seems to run from the left nipple to the acctuator, then it tees off to the bov then the right nipple runs to the boost gauge and the fpr

[Dboyizmlg]

Yes I see, that is incorrect.

Set it up the way I described on my last post.
Left nipple should go to fuel pressure regulator, you can T off this for boost gauge if you like. I prefer not too though, lol.

Right top nipple (fat one) should go to the BOV and "T" off this one for boost gauge! I have it this way in my car.

The actuator should go to compressor housing on turbo (if the housing has a nipple), or install a fitting on your hot pipe and run it to that.
Don't "T" of this line unless it's for a boost controller only.

[lunzee]

Okay. What issues could that be causing?

[lunzee]

Drained oil, added proportion amount dipstick reads good. Issue haven't happened today

[mr.nismo.]

What the fuck is going on in your bay?

1. Fix your vac lines like dboyizmlg said. Get that (boost gauge?) line off your FPR line.

2. EBay turbo? Or just waste gate?

3. Theres a line running off your waste gate line. Usually for boost controllers. Where's it going?

4. Was that a VQ dip stick? What did your oil level read with the SR dip stick before you drained it?

[lunzee]

1 vaccum lines are fixed

2 turbo and wastgate are both godspeed

3 to the bov until I can tap the hotline for the wastegate

4 it's was a little over 4 1/2 quarts before, and the dipstick had the tube replaced, so the oem sr20 dipstick does not work, whatever this dipstick is, reads correctly.

[lunzee]

So did a track event, blew coolant hose, transmission exploded. Pulling the motor to redo everything correctly, anyone have a guide? Or anything similar? I have a pretty good idea what I'm doing just want a guide

Lol, not enough gear oil in transmission?:facepalm:

Sorry I think no one is going to have a "guide".
Google is your best friend
:)

[lunzee]

No I slammed third so hard I ripped my shifter out of the grand, gear oil went flying, zip tied it back in and kept drifting until it gave up lol. I was looking for a link to like a Haynes Manual or something ha, not a step by step

[jr_ss]

The future of 240sx owners, what a waste...

[lunzee]

Yeah your right, it sure is a waste to enjoy yourself, who cares if someone thrashes their car? If that is what they enjoy, that's what motor sports are supposed to be, fun. It's people like you that judge and think they are better then others that are the issue.

[jr_ss]

You come in here asking for help, some of us give you guidance and you attempt to fix it, which is better than most. However, without fixing your issues, or even narrowing down what the cause/s are, you go out and flog the shit out of it. It breaks and ultimately you come back asking for more help, which in turn provokes me to post my comment.

I'm not against having fun, but common sense says to fix your shit, then go and have a good time. If you have money to burn, by all means throw it in the fire. I do not believe I am better than anyone else, but I do believe I have more common sense than most of the new "kids on the block" round here.

I hope you get the car back up and running, but knowing what the actual cause of why your engine was puking oil would've been a key point in justifying "starting over".

[ultimateirving]

I'm laughing inside you did a track event with the car in that shape. Well it's no surprise but hey now at least you get to rebuild it all, remember there is no such thing as a "shortcut"

[lunzee]

I realize the car had issues, narrowed in down to the rings, retrouted vaccum lines correctly, got the acctuator down to below 10 psi, nothing I could do but pull it out to replace rings anyway, might as well enjoy the day regardless

[Kingtal0n]

at least he has the balls to come in here and tell us he broke his shit

a lot of people would just stop posting, or say they "fixed" it. You can often tell because there is short mysterious silence between the two.

Take your time rebuilding it, I recommend a new longblock to skip the bottom end part, however, or I have the feeling you will be posting up pretty soon how it failed after 500 miles. Not because you are incompetent, but because it may take several rebuild/failure cycles to get the feel for how she wants to be put together.
Good luck.


I'm starting to keep track of those rebuild disasters, those that people are actually bold enough to admit they broke anyways. Often, the fault is in the machine work, surprise.

i bet you're having so much fun now that your jank ass car is broken

[lunzee]

I wouldn't doubt it, but ideally I would like to find shop to rebuild it for me, I realize this could get pricy but I'm trying to do this right, rebuilding it myself is my prefered path, but with the job I work I am very short or time, so realistically I need to find a shop as close to local as possible that is competent enough to put together an sr without costing me 5000 in bullshit

[lunzee]

I had a great time at the track day, drifting with friends is a good time, the motor was already on its way out with extremely severe blowby, it was completely worth it in my eyes, so enjoy your nice car and your snobby attitude. I'll continue working on the car and asking for help as i feel needed. :fawkd:

[bataangpinoy]

my car sucks too don't feel bad
