Toyota 2L/3L oil consumption, breather pipe modification?

Post by **high n mighty** » Wed Mar 16, 2005 5:32 pm

I need information(links etc) and peoples opinion on modifying the tappet cover breathing system on a 3L.

This is part of a court battle and many mechanics disagree with the drilling of the baffles etc for better breathing when a newly rebuilt engine blows smoke.

What are your thoughts and can you link me to some info please

So I guess none of you guys have heard of it either?

Sure have, it's called Blow By. You can install an oil catch can in line from the rocker cover to the air intake to help prevent excessive consumption/smoke etc etc.
Just make sure that the inlet and outlet pipes on the catch can aren't restrictive (ie 16mm or smaller) as the crank case pressure on a diesel can blow gaskets.

I tried a ricer catch can on my turbo'd lux, but the inlet/outlet pipes were 2 small and kept pushing the hoses off the ends. Thought about using a home made jobby with some sort of filtery type steel wool kinda stuff in it to trap the oilyness but that's as far as I've gotten.

if a new engine blows smoke there is aproblem

Thanks for the answers guys, you basically agreed with em.

Any more input anyone else???? I need solid answers with links or solid material.

Post by **high n mighty** » Fri Mar 18, 2005 4:07 pm

Guys, anyone know of a site with the exact details?

Post by **killa** » Fri Mar 18, 2005 7:58 pm

I've read a few but not bookmarked any. Unfortunately you'll have to do your own searching.. :turn-l:

Post by **high n mighty** » Fri Mar 18, 2005 8:30 pm

Been searching killa but to no avail, maybe I need to search a specific part number or something stupid like that

Dude.. have you tried install an oil catch can, or running the engine with the hose into a glass or something to see if/how much oil is forming in the rocker cover...?

If you have had the engine rebuilt there should be none... so could be un-burnt fuel from an incorrectly calibrated fuel pump/boost compensator?

I maybe i should just go to bed and stop waffling.

yeh a big catch can your only option, maybe a couple ricer catch cans in parallell

a catch can shouldnt be very hard to make, a big can, prolly 1 litre, a pipe coming in top right, pipe coming out top left, steel wool inside to stop oil/vapours getting out, youl prolly need 25mm hoses.

you will need to empoty it every now and then tho

or you could add a capilary tube at the bottom of the catch can feeding back into the oil system, but that may feed some crap back into your oil aswell, filter?

that may be big enough, 19mm hoses.

obviously your not happy about the smoke blowing aswell, hence the court case, so whats the story :S

Post by **high n mighty** » Sun Mar 20, 2005 5:01 pm

It is a big long story mate, I would prefer to tell it another time, I basically want direct information that this is a problem on 2L and 3L motors.

It is obvious to me that a new engine shouldn't be having blow by but this case goes further and it has been proven that it was the turbo seals on the freshly built turbo were letting liquid oil flow out of the exhaust, although the mechanic keeps trying to come back to this breathing restriction that is supposedly common in these engines.

I have held back from posting this for months because the internet is about as private as princess Dianna's life but at this point I couldn't give a fark cause the cards have been put on the table in court already and I have nothing to hide etc etc.

I need to find further information on this breathing modification in a real rush, I have only days before the deadline to accept an out of court settlement from him but would really love to nail him in court given the correct and official information. I would speak to Toyota themselves and get some concrete information off the head guys but that would take weeks for a reply.

By the flavour of what has been posted so far it seems that you are all in agreeance with me so I will lean toward pursuing this to the next stage which will cost about 5K more although it would be nice to go into the court room armed with some official and correct information.

Can anyone help please :oops:

Craig, try giving toyota a call rather than emailing/writing, ask to speak to someone in the tech dept and get them to fax you some info straight away explaining the situation... or get your lawyer to ask them.

Otherwise, try ringing some of the diesel workshops around, west end, brunswick etc, and asking them to fax any info they have.

Give me 10 while i search the surf forum for you...

Hrm... putting thinking cap on here, now im no diesel mechanic... rebuilt engine they would have stripped it down, cleaned all the gunk out etc and put it back together, rings/seals the lot.... so technically there shouldnt be anything in the engine to block the rocker cover breather, increasing the pressure inside it, like r00ted seals... unless they were careless and left a bit of old seal in there that managed to block the breathing holes etc.

How much boost is the turbo running? has is been hi-flowed etc... still boggles me that a rebuilt engine and turbo could blow a seal, unless its faulty workmanship. If the engine was 300,000km old and never seen a spanner maybe...?

Post by **high n mighty** » Mon Mar 21, 2005 9:36 pm

Not hi-flowed and only running 7psi

i going to use a ricer one from auto barn after i take my intercooler of and clean it they can get a fair bit of oil in the cooler and not good for flow

think they are $100

that's what I used and the inlet/outlets were too small.

Post by **high n mighty** » Tue Mar 22, 2005 5:52 pm

So we are all agreeing that a newly built engine should show no signs of blowby

As I think I mentioned earlier, I have proven it to be turbo seals that were causing the smoke(turbo also built by this mechanic), but he is claiming a problem on the 2L and 3L motors that required modifications to the breathing systems :roll:

Anyone else with these engines ever heard of this or had these supposed mods done??? I have a sketchy document supplied by the mechanic in question but have never heard of this previously.

My parents have the same model of hilux with only 140,000kms on it and they have never had a puff of smoke. Surely problems would arrise by then

yep, and used better quality hose than the cheap clear plastic crap they give you with the kit.

HnM technically "blowby" will occur on an engine.... even new... excessive blowby should not...

Post by **high n mighty** » Thu Sep 01, 2005 10:22 pm

I was reminded by Dan in another thread to reply to this(in an arse about way

).

I settled out of court for only $5000. This didn't cover anything but the rebuilt engine that blew up after only 4,500kms. I was left with the rest of the $14,000 costs of his debarcle so I will be paying it off for a long time and probably not wheeling for a long time after I sell my lux cause I can't afford another 4wd to actually wheel with atm.

The seals on the turbo went again just recently and the vehicle hasn't been driven for months previous.

I am starting to think the seals may have been something else and am trying to find the problem before I just rip the thing off(I don't regret taking him to court cause he shouldn't have charged me all this money for something that was never fixed).

Thats the high and low of the whole debarcle and unfortunately I can't publically slander his name because I settled as opposed to getting a peice of paper from the courts telling me he was wrong.

Slander is: Oral communication of false statements injurious to a person's reputation; or a false and malicious statement or report about someone.

However if you were to let me know the place you got your engine rebuilt, because i want mine done and would like a quote; that would be perfectly legal

This probably won't help now ... but out of interest

I once owned a 2.4 turbo that developed a similar problem in that it had oil leaking from the turbo oil seals. At first I thought that it must of been worn out, but after consulting with Mike Vine Turbos, I discovered the problem was caused by insufficent oil drainage from the turbo back into the motor. Mike Vine fitted a larger drain tube from the turbo with an new fitting that was brazied directly onto the side of the sump to allow pressure free drainage, after this the problem never reoccured. Mike Vine told me that this is a common problem on turbo motors when the crankcase pressure increases with age.
