Breather problems

[mike's r5]

Hi guys have posted on Facebook page but thought I would post here as can track it and update.

Have a problem with a friends 5, it's chucking oil form breather pipe, I have now done cup breather mod and no change, it only does it on boost at idle it's fine but go round the road and have a puddle of oil out of breather pipe, I have checked the breathers are clear without car running but when I blew down the rocker pipe oil comes out of sump breather tube. I take it this is not normal. I will be doing a compression test this week as some have said piston rings. Have also heard the turbo return could cause this, and can hear a bubbling from turbo when engine off. Has anyone got anything else I could try. Thanks

have you checked piston comps mate id do that first, worn rings cause probs like this

Does sound like the symptons worn rings would give

How much oil? Splash or a good soaking?

A good soaking. Was dripping on the floor after a quick drive round block, I just don't understand why oil is coming out of tge sump breather tube when I blow down the rocker tube.

There is a gallery that goes from the top of the engine to the sump, if you blow in there it will pressure the sump and push oil out abit mate
Remember when you fill the engine with oil in the rocker its got to go to sump somehow ;)

Just spoke to my m8, and he said if u blow down the tube for the sump it is bubbling like it under the oil is this supposed to happen. Thanks

The breather pipe is submerge on some sumps, its normal mate

Had the same problem. I lost nearly all my oil in a 15 minute qualifying session.

Blocked T peice from rocker cover .
