Hi guys, did a bit of routine maintenance on the Hawkeye STi today and found there to be quite a bit of oil residue floating around in the intake manifold. Figured it was time to invest in a oil catch can to sort that out.


Seen a few on the market by the likes of Perrin, Crawford performance and Grimmspeed.


Can anyone suggest which would be the best one to go for?


Cheers

Interested to hear other peoples thoughts, too.

Not sure on makes but I've heard baffled ones are what to go for as a lot aren't.

i have a 3 port obd baffled one.
does the job perfectly. i dont return to sump though i just empty it every few weeks but there is a fitting on the bottom of the can if you want to return to sump and be maintenance free.

lewisdj

I will definitely get a baffled one that separates the oil and air into fresh useable air that can be returned back into the intake manifold


Really like the Crawford Performance one although they are bloody expensive!


Have seen a few cheap ones on ebay but doubt they will have any sort of filter in there and just be a container to 'catch' the oil.

lewisdj

Just had a nosey at that one, looks very nice!

avoid ebay crap and get a decent baffled one, i fitted mine when i fitted an fmic and it keeps the pipework and cooler clean.

there was always a thin film of oil inside the tmic without one and this was what i wanted to avoid.

very well made for the price,there was a group buy on them last year i think.

get in touch with them and see if another group buy is on the cards

lewisdj

Yea I've noticed a thin layer of oil in and around the fmic pipework. has the oil catch can cleared up all oil the oil residue and leave no traces of oil in there?

When you look at what actually comes out the catch tank I'm not sure if i'd want it going back into my sump anyway for the sake of emptying it every so often.

its mostly just moisture but i wouldnt either, it wouldnt occur in a track car so much but does in an everyday use car.
the real issue is fitting it in somewhere

I have an OBP with RTS. Any minor condesate that collects in the return pipe will evaporate when the engine is up to full working temp for a decent time.
They are difficult to fit in the space available. I have mine fitted on the N/S chassis rail.

the obp one is large i managed to get mine on the passenger side suspension strut after making a bracket

lewisdj

Those obp catch cans look gorgeous! Although there are so many to choose from.. What capacity one should I go for? Surly 1 litre is enough. And also, do they return to sump? Think I'd prefer one that doesn't do that and I can manually empty. Some of the crap that gets caught in there I don't think I'd want going back into the motor

This...

It can be blanked off if you wish.

I've just had the RCM Track Attack one fitted to mine ��

obp 1 litre is fine and as said above has the fitting on the bottom if you want to return to sump if not leave blanking bolt in place as i did.
just make sure you have room to fit one as my car and bluebyyou above both have fmics so have slightly more room in the bay.

heres my oil catch can,unsure of make and if it returns to sump or not though

lewisdj

Those RCM catch cans are gorgeous! Super sexy looking things, although they should be for £330 in VAT

lewisdj

Think ive decided on this one.. Emailed obp Nd they said they can't provide oil lines for the tank and said I would need to get them from A separate company.

Can any one Point me in the right direction for which oil lengths/diameters I need to plum this 3 port catch can into my front mounted inter cooler sti engine?

Cheers

You don't need oil lines just normal rubber hose,its not under pressure or hot

lewisdj

Ok cool, any idea on the best place I can get some from for this setup?

I read that you're better off with oil lines as eventually the particulates would eat through rubber lines.
TBH though the amount that actually goes through there - probably would take an age to go through.
I have braided lines on mine but only because I'm a tart.

One thing you need to be aware of when fitting the breather pipes is that the OBP cans come with either 12mm spigots or 15mm spigots. The 15mm ones are what is recommended for newage cars, but they're actually the wrong size.

There are 2 breathers on the the cam covers, one each at 12 & 15mm. Only the 12mm pipe has a splash shield behind it to prevent direct ejection of oil splash from the valve gear. So you need to buy the 12mm spigot can to make the best of the installation.

How do I know this? Because I bought a 15mm version and Paul@Zen then showed me what I have just described and he subsequently had to modify it by welding smaller spigot on to make it work as it should.

lewisdj

Very useful information there. Do you think Id be better if buying a full catch can kit with all the correct size oil lines and fittings, rather than messing around and installing spigots onto the fittings. Jjst want a trouble free installation that isn't going to leak!

You won't need to modify anything if you buy the right bits.

I had an OBP can before (looked and felt very well made) but took it off.

Yes, it did eliminate the oil in the cooler. But, because my car is a daily driver, 30 miles to work and back each day, part of which is sat in traffic, it had a lot of mayo crap in the pipes as well as the can.

Looked like the mayo stuff was building up so much that it would eventually make its way back to the engine. So i took it off before that happened.

I thought about using clear piping, so I could see how far the mayo stuff was travelling up the pipes, but in the end lost interest and took the can off.

I had it secured to the passenger strut too, and it was also a pain having to unbolt, empty then bolt up again.

I reckon they work well on track cars, but on daily drivers i don't think they are worth it, unless you live somewhere very hot, so that condensation doesn't build up in the pipes.

My motor is a fully forged unit so it does seep a bit more oil than standard engines, it's mainly a weekend car so does get a bit of stick now and then. I think id benefit from an oil catch can
