just finished building my 96 2000 since last oil change ive done 100 miles checked everything tonight oil level perfect and nice and clean, water level spot on but looked at catch tank and it was full of water and slight very slight oil.
any ideas?

 

Prety normal. Thats what the catch cans for. It just picked up all the engine condensation

 

cool was worried it was a serious issue

 

mine fills up in a couple of weeks due to using car for short journeys at the moment.nice to know that all that crap isnt going back into the intake.

 

That reminds me i must check mine again.

 

was just bit worried after two years building and 5 grand in parts

 

mine runs a lot better since it was fitted.i no longer vent to air now as well and the "cleaned air" goes back into the inlet again after talking to alan jefferies.

 

looks like its something more serious, did forty miles in it tonight and it has filled the catch tank with oil.

 

How are your pipes set up?

 

both the rockers and the crank case all teed together into catch tank then vta

 

Put a pic up of how you have the pipes mate

 

they are all hidden cant really see them on a pic.
the drivers side rocker has a pipe from there to a t with the crank the to another t which has the passenger rocker on it and the catch tank

 

Ok,the rockers should feed 2 separate ports or be Teed together for a 2 port. The crank case breather goes to the other port & the PCV must be blancked off both on the manifold & where it goes on to the crank case breather. If it's not set up as described you may have a serious breather problem.

 

excuse crap diagram

 

This is not really right, & what have you done with the PCV?

 

pcv is blanked off

 

Ok, it looks like all breathers go to 1 port on the tank. The best tank is an OBP 3 port, but a 2 port can work. Crank case needs it's own port then 1 or 2 ports for rockers.

 

ok buy new tank might try with three bottles tomorrow and see what happens, does it matter on the height the tank is fitted as mine is mounted to the rear of the engine bay just on top of the chassis leg

 

mine is 2 port with the crank and head breathers tee-d together and into one port and the other port goes back into inlet.didnt see the point in replacing loads of pipe work when the original pipes all end at the inlet so just took feeds from there.
excuse the crap pipework it came with kit but replacing with black hose.

 

The location sounds OK. As a rule the higher up the better but not vital.

 

well after running separate pipes from each breather into three bottles and going for a drive first signs are good not one drop of oil, although it does seem to be breathing heavy ish will get the other scoob upto temp and see whats thats like as a comparison. thanks for all the help and fingers crossed that is all the problem was

 

Looks like it's sorted glad it was not too serious.

 

yeah i'm glad as well, gona keep it on the temp set up for hundred or so miles and if still ok will buy new tank. any recommendations on where to buy from?

 

OBP have an eBay shop. Unless you can afford a RCM tank the OBP 3 port Subaru specific catch tank is the best by far.

 

what about running three separate tanks?

 

On the 2 ports tank,is it posable to drill a hole on top of the tank for the 3 port?Will this work?

 

In theory that will work, but iv never seen it done. Some people use 2 tanks though, one for the crank case & one for both rockers. However it is more common to use one 3 port tank as this works the best.

 

I will try and convert my 2 port to a 3 port catch tank.Will post pictures when it's don't.

 

What difference does it make how many ports? As all the ports are interconnected in the engine, ie blow in the drivers rocker and the air will come out the left side and the crank and vice versa.
I personally have my two heads VTA then the PCA is left as is.

 

I made my 2 port to a 3 port.Made be me this afternoon.
