It’s only sightly overfilled when engine stopped so when running should roughly be sitting on the full mark. Will prob try the second catch cam idea next if the restrictor doesn’t work. Cheers for the input fellas

26 covers?

Yea its vented to atmosphere,, but before i made the bigger baffled can, it filled the can in 1 lap down the drag strip. a few more laps on the drift track. Its still got 25 covers so if this doesnt work will have to get a set of 26 covers.

yea im running brad pen, some decent oil. Is that another line? if theres a breather at the bottom of the catch can wouldnt that just force oil out as it being blown down by the tappet cover?

Yea i agree,, that did suck! with the 1mm restrictor what do u reckon would be safe oil pressure at full noise?

Hey mate yes is bigger than 2l, it has 2 pipes from top of catch can to the bottom with 2 baffles with only a small gar on the edges of the can so air can pass to the breathers at the top of the can. att hose are -10 braid and go to almost top of the sump. Was maybe exaggerating withthe massive. but after a few corners was enough oil spraying out to coat the intake side with oil. Restricted the front to 1mm and rear is blocked. but it was a 1.25,, so hoping this may make a little difference. find out this weekend when i hit the track. Nah id doesnt empty it, was more of a light mist coming out. just looked bad as everything was soaked in oil. oil levels didnt drop too much tho. Running the aviad external pump. Watched it today on the dyno and at full noise was sitting at 800 kpa, so bout 120 psi. which we thnk is too much. Gunna try wind it down tomorrow morning. Just gunna ring the up and see what ive gotta do. See how we go..

Nope, did the compression test before pulling head off. 160 or close enough to all cylinders. not blowing constantly but on a few of the big longer corners.

Hey guys so as the headline states im still blowing oil out my catch can. So ive done plenty of reading on the oil control page and thought i had most of them covered. Ive got a massive catch can baffled and vented to atmosphere, head drain/breather, can returned to sump and another vent from catch can to top of sump. Thought i had a 1mm restrictor but just puilled the head off to find it was 1.25. So ive tapped a 1mm on top. Just wondering if this will be enough or will the problem re occur. Its a track drift car running on e85, so havent had a chance to run it yet. Just fingers crossed the 1mm will fix it. Also running a aviad external pump setup. Has anyone had experience with these just purely pushing too much oil volume? will no in a couple week but just gettin peoples thoughts. Cheers

Still for sale?

Sweet thanks for the info guys, am now thinking 4" dump into 3.5" straight thru with gate to atmosphere. Hopefully get better flow with that

Yea its plumbed back in. Itll hold about 21 pound. Ill try venting waste gate to atmosphere see if that works. Its an old wastegate so maybe the spring wont hold that much pressure also

Maybe the cans are too small or the wastegate is holding pressure.. It come on hard 25 pound the bleeds right off to 21 at 7000rpm. Any thoughts to as why it wont hold boost? Would like to hold 30 pound and get close to 500 kw

Funny you say that. I should have fit the wheel first cos I just got the bearing today and put the when on and it fouls out on a little bit of the chassis and the brake line mounting. I may have to look at getting different offset wheels to get around it.
