oily air filter

come to change me air filter on the 2.5 n/a doozle pickup the other day , cracked the case open and took the breather pipe off , yer kno the standard procedure, but got a face full of black engine oil, seems to be coming from the breather pipe , in to the air filter then beeing sucked in to the manifold, completely choaked the filter, hence loss of power and smoke. so dropped the breather down the side of the engin for now, with new filter seems to run better but still smokes ? any ideas

What colour smoke is it making now? Blue / white / black ? Is it the same colour smoke it was making before?

yeah blue , the same smoke as before

might be why?
anyhow , the vapour from that tube is very toxic and can cause irreversable health problems. oil vapour/fumes is increadably bad for you, much much worse than exhaust fumes.

i had mine running into the chassis but when the car was in slow traffic it used to fill up with vapour.
really , your engine bay needs to be fume free if you can help it.

ah but if the breather pipe goes back on it will clog the bloody filter up again and back to square one a dirty oily filter and more smoke

It shouldn't breathe that much oil, is it overfilled with oil? or is it just breathing very heavily anyway? Wheres POS when you need him...

its not over filled, i thinks its just breathing heavily?

get it to quit the fags then

should do really, but its a 23 yr old truck, cant just go tellin it what to do, got a bad attitude with it, will only chuck it back in me face

ah but if you dont

''Oil vapours often contain organo-phosphates, which cause short term symptoms like nausea, disorientation, headaches, tingling and fatigue. Long term affects are memory loss, permanent disorientation, fatigue, loss of visual percetion, loss of mental agility and speed, loss of co-ordination and depression''.

id put it back if i were you.
you arnt solving the problem buy removing the pipe , just its effects on your filter.


the oil could be down to a lot of things.
blocked crank case breather, old thin oil , a worn engine /rings/bores , oil pick up blocked in sump , also remove the dip stick , if it is pressurising it will spit oil out the dip stick tube.

mine does it but i just change the filter when i change the oil.
try some 20w50 oil in there.

not getting no pressure out of the dip stick tube at all?

when did you change your oil last? and what did you put in there?

extra virgin olive oil shunt it be?

think im rite in sayin the fella put castrol magnatec diesel 10w 40 bout 6 month ago when i had a bit o work done on it

yup ,i used that in mine , it leaked out of every gasket on my engine.
change it for a semi decent 20w50 mineral oil.

magnetic is good for newer high performance japanese engines but crap for a 20 odd year old landy.

ive had decent results from castrol gtx.

I'd leave your breather pipe disconnected for the time being, or at least just until you find out the cause of the problem. The last thing you want is the engine running on its own oil (via the air intake) because it will start to rev higher and higher and there's no way to stop it; well besides somehow blocking the air intake but it will more than likely find somewhere else to draw the air in from. If you say that there is no pressure build up in the dipstick tube then there can't be any blow by. Are you sure you checked it right? Just press your thumb over the dip stick tube when the engine is up to temperature and some revs. Give it about five seconds and then quickly release your thumb. If there's a big hiss, there's a potential problem, if there's just a little "puhh" then it's fine and is more than likely just any remaining oil in the intake system being burned of (as suggested earlier).

If there's a lot of blow by, I'd suspect a blown head gasket, cracked pistons, worn rings or worse a cracked block. I had four cracked pistons in the same engine. Replacing them wasn't such a big job and it's run sweet ever sinse.

You really need to get the thickest oil in your engine that you can find too. These engines aren't the tightest of things!

ah give it a few seconds and a rev and no pressure present as such, so hopes its all ok, like yer said a thicker oil wouldnt hurt, have to get some asda special

just a thort, would it be an idea to get anexchange set of injectors and try them, if me existin injectors have started to dribble could it make it smoke?

that would give black smoke.

hang on a minute, i just thought about what you said.

How did the oil get to the air filter on an NA? the breather pipe is in the oil filler cap, and connects straight to the inlet manifold, spo any oil that comes out from the breather gets sucked straight into the engine and is burned.

For it so soak your oil filter it would have to be drawing air with oil in through the filter, or litterally running outta the breather pipe, and if it were doing this then it would stall, run away on its own oil, or it is did it while switched off then it would just drown itself with oil when you start it.

Does this make any sense?

Oh yeah avoid magnatec for new engines, as said above. Fancy oils have detergents etc in them, which washes off all the carbon deposits which make the engine seal - resulting in lots of smoke, oil consumption, etc. Thesam goes for those engine flush things. Great if used from new with a shiny new engine and used every oil change, with oil changes often, otherwise best avoided.
