Oil Catch Can Temperature?

Transport3r · 10-25-2010, 01:16 PM

I've been looking around to put my own OCC kit together, using a quality coalescent air filter and some Home Depot hoes.

I've decided on this filter, but i'm hesitant about which version to get. The polycarb bowl handles up to 125F Temps and the Alu bowl up to 175F. It has an insanely high airflow rating for a catch can (~200CFM), filters to 0.3 micron, and has a nice locking bowl release in addition to a regular drain.

I've heard our underhood temps can easily reach 120 on a hot day.
Should i just spend the extra 10 bucks and get the metal bowl?

Yes! Our cars get pretty hot under the hood. I would say easily over 120 degrees.

I don't know, it never feels hot to me, even after driving it..guess I never paid attention.

Putting one together is a good project...but the BSH Catch Can is worth every penny and the best out there...worth the price of admission.

Transport3r · 10-25-2010, 03:34 PM

Allright, it's settled then. I'm going for the metal one.

Although the BSH can looks like a very solid piece of kit, and I like the fact that they have metal adapters for the PCV connections.
However, I'm a control freak, and i want to be able to replace the filter element and detach the bowl from the filter to clean, etc.

OCC temps? I think youre over cautious.

Hi, word of caution. You want a coalescent filter but Ingersoll-Rand is a manufacturer of (relative) high pressure pneumatic systems. I expect the pressure drop over this filter to be such you'd see NO flow across it in a car, it could becomes a $160 plug. Do a search on Donaldson, Fleetguard, Mann&Hummel, and see what sizes coalescent filters they do for truck diesels. Flow is pressure differential related. You'll probably have not even 0.1 Psi to play with.

Under the hood gets VERY hot, especially if youre going to drive for 2+ hours. It gets so hot that i couldnt open my hood after driving once because of the heat.

Home Depot sells hoes?

Which aisle?

Transport3r · 10-25-2010, 06:01 PM

Thanks, that is a very good point. I hadn't considered the pressure drop in an extremely low pressure case. However, wouldn't the relation between the resistance and inlet pressure be proportional to eachother?
AR design's can is a pneumatic filter as well if I remember correctly?
Imma do some more research

also, let me see what my price is from work. we usually get a REAL good discount from Grainger.

i think the position the catch can is mounted in matters, too. the ar design catch can has the most ideal mounting location, IMO. you don't want the catch can over the exhaust manifolds/turbos for the best results.

You prefer the AR over the BSH?

all day, it's why i currently have it installed on my car

Everyone prefers what they have on their car, any DIY for it?

i bought it for 2 reasons:

1) ar design knows how to turn out high quality parts
2) it's the only n54 specific occ that mounts in the front driver's side corner of the engine bay

as i eluded to before, you don't want your oil catch can sitting on top of the biggest heat generators in the engine bay

bryce · 10-25-2010, 08:30 PM

and no diy that i know of, but it's easier than installing an exhaust (at least for me, anyways)

You make a very good point, but there is no instructions as to how to install the OCC on the drivers side corner

There is only 1 DIY for the OCC

It seems the AR would be more difficult to install.

it mounts to the same bracket as the power steering fluid resevoir

AR makes awesome products, im going to look in to their OCC.

Transport3r · 10-25-2010, 09:12 PM

Thanks!

Does anyone actually have data on the flow through the PCV?
It'd be real helpful to know the massflow/pressure.

joshuo: my Norgren unit has a few un-threaded holes on the top of it, where you could tap &/ use self threading screws. A single, straight bit of aluminum would be enough to mount it to the front driver's side. Or you can ghetto rig something like I did with my norgren as they basically look the same.
