Swapped coolers yesterday and I have an oily substance in my boost pipes! Very weak tho and stinks of petrol. Not a good sign I guess. Old cooler has oily mixture in too. I had my turbo refurbed a while back and engine transplanted a few weeks ago, so not sure. Is it turbo failure? I'm running no boost due to new engine, so can't tell you how the turbo is performing.

Fueling meter needs work tho, so could that create this mess? Top boost hose, crossover pipe and throttle body clean... All bottom boost hoses oily only.

 

The breather ends up in the metering unit this is why it smells of petrol and has oil in. nothing to worry about unless its got puddles of oil in.

 

Nah, not much oil really. 1cm deep in a cup, if that. So Its all down to the metering unit then? Breather is Bailey, but old engine used to breathe heavy so probs old stored oil?? How would I clean out the old cooler? Degreaser?

 

Yeah use some degreaser and clean the hoses. Inside doesnt bother me a little bit of oil wont do any harm.

 

No it's down to the breather setup returning to the metering unit (assuming that it stil is), a lot of us breathe to atmosphere and block the return off on the metering unit, that way only clean fresh air get's into our engines and you dont get the mess you've found in the boost pipes or IC!

 

Mfi engine was designed to breathe back into the metering unit/inlet/boost pipes etc, will do no harm!

 

had someone tell me that my engine was going to die because i had oil in my ic. two rr tuners and 30k miles later and its never been mentioned since. dont worry to much mate its pretty common.....not saying its a good thing because it provokes det

 

Cheers for all the replies guys

The engine has just cleared 1,200 miles of gentle run-in, so the concern of provoking detination is minimal considering i aint giving it any beans until she's placed on the rollers and set-up by a pro.

As for the breather set up, i did have it aired to atmosphere when it was my old engine... but i was unconvinced doing it that way as all sorts of problems happened with it that way! Now with my new engine, i plumbed it back the way Ford designed it - into the metering unit.

So aslong as i keep on top of it and check regulary for increased amounts, i should be cool?

Thats good news! I sooooo cant afford anymore problems at the moment

 

exactly mate bailey route there breather this way as do ford so im sure on a healthy engine it should be a ok

 

If it does increase, would a catch tank be worth while?

This is slighlty confusing tho because its only been a few weeks since i changed the engine for a new one..so could be caused from old engine.. I'll just keep an eye on it i reckon.

 

Your right it wont, but it will do it good by not breathing back into the metering unit, as oily air increases the chance of Det!
Yeah I think they jumping the gun a bit there, as long as it's not buckets of oil then your breathing heavy and thats a sign of piston ring wear!
+1 regards Det!

Yes a catch tank would be better than it returning to metering unit, or to atmosphere (aka all over the road), but you shouldnt have enough to worry if it's a fresh engine.
Some is normal though so if it's not a lot I wouldnt worry.

 

Its not a lot no, plus it could just be left overs from the old engine... I dunno.

When i aired to atmosphere on the old engine it created bellows of smoke (you may remember my thread?) and then the engine decided to fill with mayo. It may just be a coincidence, but it all started going wrong from blocking the metering head and fitting a little filter to the breather tank.... I'll get it booked in somewhere to take a look early next week anyways

 

Oh yeah I do rememebr your thread!
I run vented to atmosphere and have no smoke/oil from my filter and all is well, lots of other people do on here too so it's not a problem, but retuning to metering unit is fine just wont make quite as much power as if you didnt thats all.

 

what i might do then is just see what the tuner says when setting up. If he says try it again, i will. Need a new filter tho... the last engine fooked the last one lol

 

haha yeah i bet!
TBH it's a bit like going from unleaded to super, you'll only gain a few BHP before you reach Det again. But I spose every little helps!

 

gaining is good No matter the amount

 

I too had problems with the car smoking when i was on mfi and breathed to atmosphere so put it back lol, never had any problems and personally can't see you getting any power gains by breathing to atmosphere. On omex now so doesn't really matter either way now

 

Maybe its not a case of gaining galloping ponies, but more of a case of allowing the engine to run cleaner and less restricted?

 

You get gains because by removing the oil content from the charge air you raise it's resistance to Det which allows more ignition advance or a leaner mixture or both.
But it isnt much as I said.

 

I dont know why but my car didnt like the vent to atmosphere method at all. I bunged the return to metering head and vented the breather to atmos, ran like a bag of shit, this was a brand new engine with all new breather pipes and spec-r breather. I had to run venting back to metering head. Ive recently removed the ic and pipes and theres loads of oil in there, im putting it down to the small spec-r breather not been up to it, ive got a new bailey one to go on when it comes to it. Just cant work out why it hated been vented to atmos so much???

 

You need to adjust the idle mixture when you first vent to atmosphere, and ideally have a setup as it all changes when your no longer sending oily fumes into the engine.

 

We did, it was at NMS for its final setup and we tried to remove the metering head feed and vent to atmos and it wouldnt have any of it. im pointing my finger at the spec-r breather due to its size but I dont have any hard facts on it.

 

oh, mad one mate! lol
