Mk2.5 supercharged runs well and loses no oil without a catch tank.

 

I installed the catch can about 6 months ago but after a few weeks removed it. This is why and maybe there is an answer so I can put it back.

 

The damn thing fills up in 2 weeks, completely full and my engine oil level is on the lower mark. This is expensive, loss of oil every 2 weeks means fresh oil at £10 a litre, not good.

 

Is it the plumbing ? the catch can connects to the breather on the crank cover and then to the inlet manifold via the pcv valve and is vented by a filter on the catchcan, so 2 pipes.

 

Any Ideas ?

 

Thanks

Sounds like you've got no restriction now, between your intake, via the catch can, and your your cam cover, so your raw intake vacuum is sucking all the free oil out your head and it's filling the catch with actual oil, not just water vapour.

 

This happened to me - I removed the PCV valve from the system and was filling the catch tank in 50-100 miles. Solved it by putting the PCV valve back in..

 

Also test your PCV valve. It should flow one way, but with restriction.

 

I think you want to put the PCV in its original location - in the cam cover, then route that to the catch, and then route that to the intake manifold..

 

Do share a photo.

why use a vented catchcan IF also connected to the inlet manifold?

sounds like an expensive overcomplicating of the breather :whistle:

why have a vented catchcan between the inlet & engine?

 

to me thats overcomplicating the breather system & the vent seems unnecessary :blink: 

you have the vent between manifold & camcover? so engine sucking air when off boost & venting pressure when on boost?

 

 

what pcv is fitted? if its a supercharged engine then have you got the fi type pcv from a 323turbo?

 

also, if you've a problem with oil in the breather then how is the engine?

 

 

 

for a sealed system an airline watertrap seems to be quite effective at removing vapour if plumbed in between camcover & manifold.

Sounds like the plumbing is wrong - the whole point of the catch can is to avoid the inlet manifold. Here's a photo of mine (na 1.8)

+1 B) 

also, I've seen this on several cars with various catchcans... I question why theres 2 hoses from the camcover (that's essentially the same void :blink: ) and if the pcv is retained in the inlet side then it's probably restricting if not blocking that line :popcorn:

I have a supercharger, the only change I have is the installation of a small filter on the breather on the RH side of the engine, still have original PCV valve, the filter is bone dry....

By removing the PCV and still having the intake line connected you are pressuring the crank case (when on boost because you are supercharged), and seeing vacuum the rest of the time which is why your can is filling up so fast. Donut Media recently did a money pit episode where they were pressurizing the crank case of their turbo mx5 and it was pissing oil out of every seam, theirs had no can, yours does, so the can fills up rather than it leaking from everywhere.

 

Low Rider is right, delete the PCV, block the inlet manifold cap and run a line from each side of the crank case to the catch can. You should not have lines connected to the manifold if you have a vented can, it'll create an air leak. If you were to leave the PCV in place it'd never see vacuum and would in effect not be venting from that side. 

 

Zed is also right that a PCV will restrict the flow of oil, but only slightly, it's there to operate under slight vacuum and prevents any gasses or pressurizing of the crank case returning back into the head. The 323 version is just "better" made, it has metal internals rather than plastic.

@Lowender - as Zed has noted and I'll restate in my own way..., that one hose with the PCV valve is redundant, since the only flow you'll get, is the exhaust side hose to the catch can and then out the breather. You've basically got a VTA setup with an extra hose doing nothing. The pressure from the head won't be enough to overcome the restrictor of the PCV valve. You need manifold vacuum to actually permit the PCV valve to open. Any pressure in your head will just go the easiest route out.

 

If that's per the davefab instructions, well.. lol...

 

My thinking on breathing is that you want some flow through the head to get the gasses out. Ideally flow from the 'hot side' inlet, to the PCV valve outlet, and if you're putting the catch can between the head and the inlet manifold, then the catch can actually does something.

 

on an ITB setup without the inlet manifold, VTA makes the most sense, and, I recommend trying to replicate some flow through the head with a draft tube..

 

@threeflies do send us an actual photo of your setup :-)

Yes, as per Davefab instructions. They even include a blanking plug for the inlet manifold. I do understand that the PCV only works with vacuum though. I fitted the catch can in anticipation of fitting itbs.

Seems to be the same arrangement as this itb VVT:

 

50932998737_47a30f68e1.jpg

 

It seems that some people run the PCV to the catch can, thence to the inlet manifold, and run the hot side outlet as VTA with a filter. The Blink stage 2 ITB setup blanks off the PCV, and runs the hot side outlet to the catch can.

I am now also confused.

Basically there are 2 ways you can do it. 

 

If you have a vented catch can you can delete the PCV and connect the can can to each port on the head and cap off the manifold. This works regardless and the only downside is you lose the tiny bit of vaccum the PCV sees to help draw out gas, but the other side will always vent positive pressure anyway so it's a non-issue.

 

If you dont have a vented catch can you can do a PCV intercept where you keep the PCV, attach one tube from the PCV to the can inlet and the other from the can outlet to the intake manifold. However the PCV will see pressure under boost with this system and not do anything, so it's not really suitable for a boosted car (works fine on NA cars though), and in fact will likely pressurise your head as boost leaks past the PCV (one of the benefits of the 323 PCV is it can resist this, but it's marginal and not really rated to the higher then OE boost pressures most boosted mx5s see).  If your can is vented and you do a PCV intercept you'll just be creating an air leak so don't do it with one.

For this set up you can either put a little filter on the other crank case vent to just VTA, although many say it'll set saturated with oil and leak down by the manifold which on a SC car is likely right by your belts, or connect it to another vented catch can (non-vented wont allow pressure to escape this side and so is actually bad for the car and as crankcase pressure increases you'd likely see oil leaking past the seals, although this is only if the vent on the inlet side isnt able to open).

 

Edit: The existence of 2 vents on the head is mostly just for redundancy and increased capacity.

The two vents on the cam cover are to allow fresh air to be drawn in on the exhaust side while cruising, as the PCV valve is letting crankcase fumes be drawn out into the manifold and burned in the cylinders, and under sustained full throttle to allow blowby gases to exit on the exhaust side and prevent he crankcase pressurising.

There's no valve on the exhaust side to prevent gases escaping as on the PCV side and it is also under vacuum in a stock system. Im not saying that if the crank case becomes negatively pressurized it cant equalise the pressure, but I can't ever see when it would be, they are there to vent excess pressure that seeps out of the combustion chamber past the rings etc.

Well no, the exhaust side port is not under vacuum in the stock system.  It vents into the crossover tube pre-throttle so fumes will be drawn through the engine, but there's no suction applied.  It would just be blowby gases, as you say, pushed out through that port when the PCV valve is shut due to sustained high throttle.  Which of course mean fumes vent into the crossover tube while the throttle is open and there's a good airflow to pull them through the engine.
