Oil catch tank

[RBYCC]

Jesus wept. I cant even belive im replying to someone so totally clueless they think cruddy oil residue being sucked through a turbo compressor wheel is good to lubricate it, but I look back after a few days and find you calling me pathetic names, so...

I was seeing oil when the vac from the s/c was sucking it in to the airbox and over the air filter, like you do on pretty much all turbo cars with the same setup, especially when tuned or done a few miles.

Its there to suck away the oil vapours for emissions reasons, but as a consequence sucks oil too. Same on any engine.

Now the vapours go to atmo, at best get a fine sheen in the catch tank, but mostly water from the condenstation, and now my pipes arent full of oil and **** like they are with the stock setup.

If you think oil inside a turbo, intercooler, and everything else associated with it is good in any way you really need to step away from engines.

Good old internet as ever- No practical experiences of what they are talking about, who has to resort to kiddy name calling as he has nothing logical to back up his ridiculous notions.

Your not going to get the diesel types to grasp the concept of a high performance vehicle that can be and is used in competitve motorsports..

They tend to be lock step with a curmudgeon mindset and think that driving at 4/10's is absurd...

To them cruddy oil being recirculated is good but only because of the condition of what they own...

Quick to quote chapter and verse on everything but never from experience more from a Google search...
Present him chapter and verse along with SAE papers and the response is "prove it"
One cannot see unless he opens his eyes...

Keep in mind the "expert" is one who has made 20K+ posts in less then eight years..
Perhaps he needs to get from behind his keyboard and drive his car with a bit of gusto...
Surely hope he is much older then me, because if not he has missed out on life !!!

I never said the oil would lubricate the compressor, obviously that's done by the engine oil, but a slight oil mist will lubricate intake valve seats and stems, reducing seat erosion.

Actually you did ....

" You have installed a catch because you believe the oil mist MAY in some way damage your turbo's. I just don't see that and if anything the oil may act as an additional lubricant "

When one talks so much they oft times forget what they say...
Primarily because they constantly change their position...

Now I have the greatest respect for both DM and Ed and as far as this argument goes I know very little on the subject so I fully believe both of you

However, I do not agree that the the following statement can be relied on as any evidence that DM actually said that the oil would lubricate the compressor.

" You have installed a catch because you believe the oil mist MAY in some way damage your turbo's. I just don't see that and if anything the oil may act as an additional lubricant "

The statement includes two sentences and the reference to the additional lubricant is contained in a different sentence to the reference to turbos, assuming by turbo you mean compressor anyway

Maybe we should shift the debate to pedantry and/or semantics and I'd be on firmer ground lol

Don't do it, oil is good for the valve seats and guides.

Yes but carbon build up is worse. Make sure you use a closed system breather, you need to maintain the negative preassure from the inlet to the crankcase, other wise you can cause more preassure in the crankcase system

I know that, but Stav and RBYCC seem to have a problem with it.

They seem to think that because they have seen an open breather on ultra high performance engines, that it applies to their low performance road cars.
They keep bleating on about high boost engines, forgetting that all turbodiesels boost more than their petrol engines do...and don't need or use anything more than a regular oil separator at the start of the breather system.
It's a none entity with no proven benefits other than for knackered engines that blow oil out of the breather.

I have to disagree.

Stav uses his car to rag about basically - he's not even using a catch as such, just a bottle.

Ed has never implied what you have just said.

Perhaps you have read too much into this - no one has been telling people what to do, just giving their opinions.

I've just come back from work - you should be out in the sun !

Let's put it to rest and agree to disagree...obvious that we don't share the same level of experience or enthusiasm

I doubt my current ownership of a tuned 2008 CLK63 AMG Black Series, and 2005 G55K AMG or even 1988 300CE TT ( 340HP/393 Torque M103-12V ) would be deemed even in your myopic view "low performance road cars".
Not sure if you have ever driven at speed but I doubt it...wonder if you are capable of tossing my Black Series around without soiling your knickers?...

I'm not a young man, presently know my limits, have slowed down quite a bit..
However I have held competition licenses from NHRA ( top gas...which means I qualified at 150MPH in the 1/4 mile in 1968 ) and AHRA.. both drag racing sanctioning bodies.
Successfully campaigned a factory max performance lightweight hemi superstock 1964 Dodge 330 and held a national record at 10.76/132MPH in 1967.

Also held licenses for SCCA and SVRA.
My primary road racing efforts were with a 1966 Aston Martin DB-6 Superleggera with the Vantage spec engine ( DB6/2447/R )

Did quite a bit of club work with AMOC, JCNA, JDC, RROC, BDC and showed a 1966 Jag S-Type which was nationally ranked second in class at 97.3 points.

I have many more accomplishments and not afraid to come out from behind a computer terminal...

I'll back up a few of my claims with pix...my name can be seen on the door of the superstock Dodge...
The AM was imported from the UK by me in 1983..paid 13K sterling...
Raced it for a while and sold it back to a UK AMOC enthusiast for 65K sterling in 1997.
