I noticed a lot oil got sucked into the intake manifold from the PCV system during my Hondata gasket installation. So I did a search and found some really good ideas from the S2K site.
I always knew the PCV system will have some oil in the intake ports but didn't expect that much on the TSX with such low mileage. So I went out and got an air compressor filter just like the ones used by the S2K folks. It requires a custom mounting bracket, which I'm in the process of making. I'll let you guys know how it turns out.

gogozy

thanks!! i think i will wait for that!!

gogozy

will the oil from pcv return to the oil pan if not catcher can? i hope we don't see that much of oil in catcher like S2K... i am also wondering will these oil act as lube the valve??
thanks

kangjin

what's the capacity of the filter you picked up? approximate price paid?

thanks!

JTso

iTrader: (2)

I have to look for the capacity spec... it's not very big. The price is about $12 at the local Home Depot store.

forestsoft

That is a great idea...I going to make one too...
That was quite a bit of oil, with the gasket changeout.

Maybe I can shoot some gumout, down the intake to clean it up abit. After the oil catch install...

johnny you are gonna have to show me what your doing lol ill come over sometime and maybe we can do it together =)

gogozy

will using synthetic oil help in this regard? (i mean, have less oil in the intake area) also some dealer has suggest 5w-20 instead of 5W-30, do you think using 5w-20 will worsen this excess oil condition? i am now in "change freeze" for at least 3 month because my first baby is due in late Jun but i am now worry about carbon build up..
thanks JTso for so many mod ideas!! my hand is itchy any pic for the oil catcher?

JTso

iTrader: (2)

No, changing the type of oil or grade will not help. A catch can in closed-loop mode is only going to reduce the amount of oil end up in the intake port, but not eliminate it completely.

How bad is it for the car to have oil in the intake manifold? Is this a common problem with all cars? or just Hondas?

JTso

iTrader: (2)

It's a pretty common problem (design) on all cars with a PCV system, which is mainly for emission control. Crankcase oil vapor and blow-by gases during the normal engine combustion process get routed back inside the engine via the PCV system to reburn. A little oil is normal but the amount of oil I found seems excessive. If too much oil got passed through the intake ports, it can cause carbon build-up on valves and top of pistons, thus affects engine performance.

gogozy

yes, corbon retain lots heat thus performance suffer.. but S2000 site show some pic that amount of oil is impressive (excessive) how about EGR? are you also adding a can for EGR (i don't know egr as much ) thanks..

JTso

iTrader: (2)

EGR = Exhaust Gas Recirculation. The TSX uses the PCV valve to route the crankcase gases to the top of the EGR plate. Then from the EGR plate down to the intake ports. The EGR plate on the TSX is an interesting design as it sits on top of the injector base. If I remember correctly from reading the service manual, the TSX uses valve timing overlap to route certain amount of exhaust gas to the EGR plate and then back to the intake ports for reburn.

No problem Stoke, it's almost done. We can meet so you can see how it's done.

Stokeless_TSX

cool maybe ill swing by this weekend or something ill give you a call

I've just completed the catch can installation and here are some pics. Enjoy!

Catch can assembly
I don't have the capacity spec, but the catch bottle is not very big. It's probably fine if I have to empty it at oil change. It uses 1/4" NPT for in & out ports. The build-in filter is a plus!


Custom mounting bracket
I was able to utilize the factory mounting location for the windshield washer bottler filler tube. So, no drilling required. However, I did have to hand made the bracket, including welding.


Test fitting catch can in bracket
It fits perfectly!

JTso-- What would it take in order for you to make one for someone not so mechanically inclined, or is it something they sell at the local car shop????? Money speaks big words!!!!!!!

JTso

iTrader: (2)

You can buy the filter from Home Depot hardware store (not sure if they are nationwide) or stores that sell air compressor accessories. You can also order it online here. I believe http://www.canadiantire.ca/index.jsp also sell them. Part # 58-8125-0

Optionally, do a Google search for "oil catch can" and you will find many hits. However, most of those cans are not baffled.

cmf

Thanks for the links...one more question...I notice yours has two ends...like input/ output, but the ones in the link has what appears to be only one...or do I just not see it.....
For the retarded guy....what does it mean to be baffled...I know nothing about engine components

JTso

iTrader: (2)

The one in the link also has two ports. One sticks out, one not. You just need to buy two fittings from any hardware stores or auto parts stores. The fittings thread should be 1/4" NPT, and the nipple size is 3/8". You also need a few feet of 3/8" PCV hoses.

Most catch cans don't have an internal baffle, which means there isn't any internal separators, so only oil vapor get pass through. Here is an example of a baffled can. Most other cans are just for looks with just an empty can and two ports to connect to hoses. I guess they still work somewhat but may not be as effective as a baffled can. HTH...

gogozy

thanks JTso~~
any idea the amount of oil collect in the few xxxx miles i hope it's not too much in 3 month as i can't do anything in this period

do you think driving style can minimume this? thanks~

gogozy

sorry double ..

Schizm70

JTso it looks like the output tubing is running awfully close to the pulleys. Is the tubing stiff enough to prevent travel under braking? Thanks

JTso

iTrader: (2)

Schizm70, Yes, due to the routing and the stiffness of the hoses, they won't touch the PS pulley at all. If I see that becomes a problem, I can add a zip-tie to the top PS hose to secure it in place.

Btw, after only one day of driving (approx. 60 miles), It has already collected a few drops of oil.

JTso

iTrader: (2)

Here is the result after approx. 120 miles. Notice the traces of oil dripping down from the left side of the bottle. I'm glad the oil is in the bottle instead of in the intake ports.

tony4311

did you happen to take any pictures of the oil in the manifold before you installed it?

JTso

iTrader: (2)

Yes, right here

sho-one

hmm this might be a weird question, but do the dealers clean off the manifold during any of the schedule maintenece intervals, and is it really that bad of a problem?

gogozy

Thanks JTso, am sure that thing lead to lots of carbon build up. i don't think dealer will lean it for free

Maxboost

Can you tell me exactly where the top line (running closer to the firewall) goes? I see the one of them go to the left of intake manifold but where does the other go???
Thanks JTSO.

JTso

iTrader: (2)

It goes to the original PCV connection on top of the EGR plate. If you remove the top cover (two 10mm nuts) and follow the the stock PCV hose, you will see it.

I had to route the modified hose around the PS pump and back up under the top cover using the stock location.



Edit:
Here you go. Here is a better picture showing where the hose goes.

Maxboost

So the hose goes to the that brass plug between the middle intake plenums, am I correct? Also the second picture is the "before" and the first one is "after" right?
By doing this will it increase the tendency for me to run out of motor oil faster than not having the oil catch tank? If so will I have to get an oil change more often?

JTso

iTrader: (2)

Yes, the second picture was taken from the Hondata gasket install for reference only. You will not run out of motor oil faster by doing this, because it's there to catch the oil that normally get sucked in to the intake ports.

gogozy

i am just wondering; does any of these oil provide lubrication to the intake? i assume it just cause carbon build up but i would like to hear from export!! thanks!

JTso

iTrader: (2)

I seriously doubt the oil in the intake ports is for lubrication. It's just a side effect and byproduct of the PCV system. Valves get lubed from oil under the valve cover. After all, it's not a two stroke weed trimmer engine.

dickise

would it be possible to get the measurements you used for the bracket? How much dose it cost to replace that little filter element or do you just buy another one of the whole assemblies? also how much of the hose did you need for this?

JTso

iTrader: (2)

The vertical piece is 3"x2" and the horizontal piece is 2"x2". I'm not sure the prices for the replacement filter but I'll check the next time when I'm there. I think 4' of PCV hose should be enough, but I'd get 5' just to be sure and avoid another trip to the store. I used some leftover pieces from another project. Btw, make sure you use PCV hoses because they don't collapse under vacuum.

TSX007

Great write up! Just installed the Heatshield myself today, and noticed the oil buildup. I wasn't expecting it to be that significant but it is. This is definitely on my "to do" list. Thanks for the info.

xizor

Bought mine today, but waiting to install it w/ my hondata gasket.

I got mine at Lowes (couldn't find it at Home Depot). Got the fittings, still need to find some black PCV tubing as neither HD or Lowes had 3/8" in black.

The company that makes the filter sells a mounting bracket as well, part #SX129900AV. You can find it on their website www.chpower.com. I plan on trying out the zip tie route for now

xizor

Jtso, is it alright to mount it horizontally. I ziptied it vertically to the AC line, but it still moves around a lot, I think horizontally on the AC line would be much better, but I haven't gotten a chance to see if the hose heats up.
