3TGTE Oil spewing out engine bay
|
Mon, 04 July 2005 09:18
|
 |
So I just set my 3TGTE up and its pumping out 141kw@wheels, after driving it like a poof for a ocuple of days coz the alignment was well out, I got it fixed and then thrashed the crap out of it for about 10 mins. When I got home there was heaps of smoke coming out of the bonnet. I opened her up and oil had come out of two places, one is the rocker cover over flow which is fine, just need a catch can. The other is coming out of something just behind the oil filter. It seems to be an unidentified little black box maybe 6X8X10cm which is bolted onto the side of the block. There is a black rubber tube about 1.5cm diameter coming of it which doesnt connect to anything, I think this is where the oil is coming from.
First, does anyone know what this thing is??
Second, could it be spewing oil out of it??
Third, if the answer to the second question is yes, then where am I supposed to plumb it to, or, am I meant to just block it off or what??
I may have just blown something else near this black thing and not realise, so if anyone else has a decent suggestion as what else on that side of the engine bay could spew oil out, then I'm all ears.
Thanks for your help

is it not an oil return line on the block leaking or someting? That happened to my 7Mge when i rebuilt it. Line from the oil cooler back into the block. The box/ leak being next to the filter, that makes sense.

I have a photo of the black box, but cant load it for some reason.
4agte - Please dont fill thid thread, or any other thread for that matter, with pointless bullshit. If you are really that bored, then go and have a wank.

4agte - YES IT IS....at least I dont give everybody else the shits while doing so!! FUCK OFF!!
V8_MA61 - It doesnt have an oil cooler, which is something I've been meaning to install. Are there valves or something on the side of the block near the oli filter, that you can run lines to a cooler from, that could be leaking??

how about the oil pressure switch - has the seal gone?
i dont actually know if there are lines there. M series did have them (7mge,4m wtc) but its worth a try?

Too late to check now, about to go to bed. But the oil pressure switch is a bloody good guess, it just got changed (not by me) and also the pressure guage barely moved when I moved it up my driveway earlier on despite the fact its still got heaps of oil in it.

I know the little box your talking about, funny thing is, mine isnt connected to anything either. Would also be keen to find out where to connect this to. Hopefully some one has got some answers......will post up if I find out.

yeah, thats the thing I'm talking about. I checked my oil pressure switch, thats fine. After it spewed out all the oil, I checked the oil level and it read about above empty despite the fact its sloping backwards, maybe it just overflowed coz it was too full, and that thing is a breather line??

looks remarkably like PCV, positive crank case ventilation, hose.
from what you describe.. oil pissing out rocker cover, and oil pissing out of crank case breather, it sound slike you are getting a large amount of blowby (rings fucked? how's compression?) and simply blowing oil out of the block.
put a coke bottle catch can on both for a short time and see how much oil you lose.. and if it is mist or as buckets of the stuff... either way, you'll need to investigate the reason for so much blowby.. rings? piston? maybe rings are not properly bedded yet?
oil pressure switches do fail.. had one go.. oil pissed out between the metal nut part and the plastic cover.. since oil is under pressuire there it made a bit of a mess..
heh heh, thats one heck of a dizzy.. octastic even

Well, I just installed a cacth can this morning, and plumbed both hoses to it. I took it for a spin for about 5mins and there was probably about 5-10ml in the tin when done. I did thrash it a bit but not too bad. Do you think thats too much, rings fucked?? I've owned the eninge for about 2 years and never pulled it apart, but also never ran that much power through it until recently. Maybe I'll go check the compression, any idea how much it should have??

Yeah that is a crank case breather on the block. I have mine plumbed into the inlet manifold. But never noticed oil coming out of it.
Like Oldcorollas said i'd be looking at rings/pistons broken causing that much blow by.

Sounds like a lot of oil.. I have a small can on my 3tgte and after 30,000km there wouldn't have been more than a couple of ml.
Though thats with a new engine...
My 4age probably gets a few ml over 2000km or so and thats done over 150,000km.

heh heh, i have no idea for the 3T's, but a K motor can spew out maybe 50-100ml on a long hard right hand corner .. gotta love that head design..

Yeah i've found the 3tgte to rarely put anything out the breathers.
Even after a full day at the circuit track hammering the car for 30 + laps the can is empty.

just checked compression and got 130psi on cylinders 1,2 and 4 and 70psi on cylinder 3.
Looks like a rebuild

And the 3TGTE pistons strike again Its like a recurring bad dream!
Are you running factory engine management? Make sure you sort out the detonation before you throw another set of pistons in the bin
Time to swap for a 4AG  Just kidding, get some good pistons, make sure the tune is spot on (aftermarket ECU preferred), and you'll be laughing. Oh, and if you don't have one already, an intercooler
Cheers

I'm running a wolf 3D V4, and yes I have a reasonbly big front mount cooler.
I've heard that cylinder 3 and sometimes 4 is favoured by the intake manifold and can therefore lean out a little. With my wolf I can give each injector a percentage bias, what sort of bias do you think would be necesary, 5% and 3% for 3 and 4 respectively??

sounds like something you should be discussing with your tuner

Yeah I actually suggested the 3rd and 4th injector enrichment. The tuner I use (Matt, the Hitman) when tuning my 3tgte back when it had the standard inlet manifold always changed the 3rd and 4th injector to richen those cylinders up a little.

do you think 5% and 3% for those injectors is about right?? I wouldnt have a clue how much to richen it.

Hi Nabs, knowing the 3T-GTEU reasonably well... it sounds to me like you have some damage to your engine.
In particular, while the rest of the engine is quite durable, the 3T-GTEU pistons aren't exactly the stongest & usually break through the ring lands.
Thankfully, this usually doesn't do any damage to the bore of your engine, however, you are going to notice some serious blow-by / rough running / low power.
If you have a broken ring land, you can do all you like with the tune, but it won't fix this (Although, it may have stopped it happening in the first place).
The easiest way to check this, is to do a compression test on your engine, which I would recommend you doing ASAP.
Most likely you will find one (or more) cylinders will be down on compression & you are up for a rebuild.... while you are there, spend the extra & replace the standard pistons with some forged items - well worth it for the 3T-GTEU.
Good luck

hes allready done a compression test he was wondering what he should do next time to avoid it leaning out on cylinder 3.
Having said that putting forged pistons in it wouldnt be a bad idea

Sorry, that's what you get for skim reading a thread. 
3T-GTE solution to preventing this problem =
1. The easy "spend some money solution"- Go forged pistons
2. Very careful tuning, or Run less boost (anything more than 12psi with standard pistons is really going to test how good your tune is)
141 rwkw is testing the max of standard pistons regardless...
Last time I heard...Simon is getting around 147 rwkw - with bigger aftermarket turbo, IC, good tuning, etc...& its still hanging together... but I haven't heard anyone else getting any better than that without going to forged pistons.
Hope this helps...

Well, I'm running a T28 with 14psi, so I guess this was gonna happen.
I have already increased the bias on injectiors 3 and 4 by 4% and 2% respectively. But I have since stopped driving it all together coz it started making an even louder sort of vibrating noise throughout the RPM range.
I'll whip the eninge out when I'm finshed the work I'm doing on my other car in about 3 weeks and take a look at the internals.
Thanks for your help
