in need of some help...quick

all right guys...i need some serious help...most of you probably already know from my last thread that my boost gauge has been reading 25psi when i get on it....well i was getting on it today through all the gears, and in 3rd gear i got fuel got with my boost reading 26psi. opened up the hood and there was oil all over the valve cover, the lines, took off the spark plug wire cover...oil all in there, took out the wires and oil had leaked into the boots... :( :( :( what the hell could be wrong with this thing?!?!?!? all the vacuum lines are connected along with everything else that should be connected. please help!

My first guess would be that it came through the oil cap!!! mine is only pushin 12-13 and I had to bend the inside "tabs" on the cap to tighten it up so now there are no leaks... Could a bad PCV valve cause more than wanted pressure inside? I think 25psi is awesome AND nuts!!! lol

Okay...we already established that you shouldn't be running 25 psi. You need to troubleshoot that problem before you keep making passes boosting that high and killing off your turbo.

i got fuel got with my boost reading 26 psi.

Are you talking about fuel CUT? I don't understand what this means. If you have a hairline crack in your valve cover under the spark plug cover or elsewhere, or your oil cap is too loose like Spyderman said, that could cause all of the oil to come out the top of your valve cover.

You need to find a way to control boost. It is inefficient and damaging to your turbo to run over 17 psi.

AMEN!!! I'm lookin at getting my MBC in soon and have some worries about puttin it at 15psi lol
25psi!!!! wow KABOOM

yeah i meant fuel cut...sorry bout that typo...but i took off that thing that sits under the intake (i think some call it the stock boost controller, correct me if i'm wrong)... and looked at the connectors and there was a bunch of white gooey shit in the electrical connectors...so i took an air compressor to it and i had an assload of that stuff fly all over...made sure it was all clean, hooked it back up, ran it, and i'm still hitting 25+ psi and having fuel cut...i've been trying to drive it normally lately because of this...trying not to go over 10psi around town...as for the oil...i have an aftermarket cap (that doesn't leak). but it had to of come from the cap. could running too much boost cause oil spew from the cap? i was half a quart low too...so i filled it up with some Castrol 10w full synthetic. (i always use the same oil)...anyone have any suggestions as to what i can do? everything on this car is stock except a K&N FIPK, short throw, and gauges...it's never done this until about a week or so ago. can't exactly remember when it started this.

all right everyone....thanks to EclipseRST (talked to him on aol) i got my car running perfect now :) what he told me to do what take the hoses off the stock bc, and run a hose straight from the turbo to the wastegate instead of the two being connected to the tee line and having a hose run to the bc. did that and now my gauge reads 11PSI MAX when i get on it now...and no more fuel cut :) my question is...if i leave it like this, am i still able to get an aftermarket boost controller and hook it up?

thanks for the help everyone

I don't see why not. I'd hook it up as per the instructions!! and take your time dialing it in... basically you just did half the install of a MBC by disconnecting the stock BC Remember Patience is not only a virtue but the key to saving your motor from going KABOOM :naughty: lol. Start slow/small ... just like building measure twice and cut once!! Good luck man! As for the oil.... DONT GO TO 25PSI!!! lol :grinno: The only time I get any oil out the cap is when I really get on it :evillol:

Ok now I'M scared. I removed the BCS entirely, capped the turbo nipple, and capped the intake-->BCS nipple. Teed one hose from the MBC into the BOV line, the other to the WG.... no probs yet, but im getting creep....

hmmm...according to this site > http://www.belitski.com/cars/talonmods/turbo/vfaqhallman.html

you did it right. i should be getting a MBC soon and i'm hooking mine up the same way this site says...does anyone know if this is the CORRECT way of installing a MBC because if you capped the turbo nipple and the intake nipple, teed a hose from the MBC to the BOV line and had another line from the wastegate then you should be ok according to this site....but if you're getting boost creep then i dunno...anyone hook theirs up differently?

hmm...anyone have any experience with this MBC? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7918183673&category=42604

$9.79 plus $5.99 shipping...i just don't want to get a shitty one but i am on a tight budget.

Creep doesn't have anything to do with your boost controller. He hooked it up right. Are you sure it's not boost spike? I haven't heard of creep on a T25, if that's what you have. If you have bigger, then it's plenty normal... and solved by other means than trying to blame it on the MBC.

creep sorry, I meant spike.

Normal for a few pounds higher than what it settles at on a stock car. Might be to do with the turbo's size or the internal wastegate, but it's not something to worry about as long as it settles.

Odds are the stock BCS (boost control solenoid) got stuck closed and isnt letting the signal through to the WG. Or is that a bleeder setup. Cant recall. At any rate, as long as it works with a straight vac line, the MBC will work. Luckily the motor survived the "testing" process ;)

allright i got a hallman MBC...hooked it up...and no matter how much i adjust the screw, it constantly runs at 22PSI...i AM adjusting the screw properly....i hooked up the line at the bottom of the BC to the wastegate and the line from the side of the BC to the compressor housing and ziptied the MBC so it won't move around...i did exactly what the directions told me....what the hell could be wrong!?!?

That sounds back asswards. The bottom should be the source, the side should be the output to the WG. I just woke up, so someone correct me if I'm off my rocker...

i just followed the directions man...even has a big ass picture of the MBC and has directions next to each line on the BC and tells where they go......should i try reversing these? will any damage occur if they're wrong?

ok nevermind...how the hell do i remove the wastegate? i fucking broke off the nipple on the wastegate and now i'm really fucked. my friend has a wastegate from a small 16g...would that work on mine?

I Dont recall what turbo you have. If its a mitsu turbo, yes. If its the t25, no.

it's the t25 :( but my dad works at a steel mill and this morning he took it to work with him to have the guys down there thread a new nipple into it....hopefully they can fix it......if they threaded a new niplle in it, it'd still work, right?

ok i got the wastegate back...they fixed it...looks brand new :) couldn't even really tell that the nipple was broken off....they just told me to put some JB Weld on the bottom part....so i did and i'm just waiting for it to dry now :)

somebody correct me if im wrong but i heard somewhere that part of the cause of boost spike is the stock vac/boost control lines expanding under pressure and that you should replace the lines with high pressure fuel line and clamp the ends to keep it from leaking and make the wg respond faster. does this sound legit? i dont have a turbo so i havent tried it but it sounds right in theory.

just wondering if this was normal...i finally got the boost controller to work somehow and now i have it set for 15psi...but in second gear when i get on it, it hits 15 psi for a couple seconds and slowly drops back down to around 10 - 11 and in 3rd gear it sticks at 15psi and doesn't move...is this normal or is this a problem?

thanks for the help

I have been suggesting high pressure fuel line for years.

The boost dropping you describe is normal for a T25. On the lower end of normal, but normal. IIRC, mine would hold 14 psi. Every car and setup is a little different.

all right....now for the next question....i've read different things on different sites about the MAX boost the T25 can handle....some say 16, 17, 18 and even 19....i don't wanna blow my turbo up, so what's the safest MAX psi i should set?

17 psi--anything higher heats the air too much to make it worthwhile.

all right thanks for the info...but listen to this shit guys...just about 30min ago i was driving to pick up my girlfriend, driving on the busiest road in the city...and all of a sudden my car completely dies. no power or anything. and i still had fuel. pulled it over, wouldn't start....finally it started. got to my gf's, and it died in the driveway...by this time i was SUPER PISSED so i punched the steering wheel as hard as i could and the fucker started. then it ded again 5min later. so i went under the dash and jiggled around the ignition switch, and it started and stayed started...could i have a short or something in the ignition switch?

sounds like you have a loose plug on your ignition switch. check/clean all your connections and if they all look ok then you may need a ignition switch. or you canget rid of the ignition switch completly and do a on off switch with push button start

ok guys...my friend thinks my ignition problem could possibly be from the wire running from my oil pressure gauge to the ignition switch...well on the igition switch, there are 5 or 6 wires and i hooked my oil pressure gauge up to the really fat wire (i think it's white?) anyway is this the correct spot to splice into? or doesn't it matter? this is a diagram in my manual...

Ignition Key Position -- Terminal No
1 2 3 4 5 6
LOCK
ACC *------------*
ON *-*----*----*
START *-*-*-----*

so which wire does this thing really go into? my friend swears up and down this has to be the problem, but my oil pressure gauge works fine...thanks for any help

ahhh damnit that diagram turned out crooked...well here i'll try explaining it...

Terminal 1 - ACC, ON, START have the *
Terminal 2 - ON, START have the *
Terminal 3 - START has the *
Terminal 4 - ON has the *
Terminal 5 - START has the *
Terminal 6 - ACC, ON have the *

could it be the waste gate actuator itself? If there is a diaphram inside ... maybe cracked... just a guess!?!?!?

how many miles u got on your car?

80,xxx....but the thing has a new short block, new clutch, and turbo...it's not anything with the turbo unless the turbo has something to do with shutting the car off which i highly doubt...it's definitely something electrical. my car will just shut off out of no where. engine stops completely, speedo and rpm gauge drop off to nothing...has to have something to do with the ignition switch i'm guessing, but i'm not sure...
