not sure what to call it, but lately im getting alot of oil blown out of my breather/catch can. The oil that spits out is emushlionsed (really dont know how to spell that) but what drains out of the sump aint and the coolent isnt mixed with oil either.
the car is a vtr turbo and was fine upto about a month ago

sounds like the start of a head gasket problem

dont think its head gaskit as there is no mix in the sump oil or the coolent

bump, there a fair bit of oil burning in the exhuast aswell.
Could the oil preshure be to high.

yes if its anything like my old 1.1 when it started to die it was because of the piston rings starting to die a death OR it could be the pipes for the catch tank aint big enough cauing pressure there to

take dipstick partially out just the top and put your hand over the rocker breather

did the dip stick test and it bubbles out oil, so does mean the rings are gone

valve stems usually on start up only mate
how badly does it bubble out? like a squirter or slowly? sounds like they are on their way one problem with catch tanks is that if the pipes are to small in diameter then it makes the engine breathing a lot more well restricted

by the time you have messed about getting the rings and taking everything else apart cheaper to slap a new bottom end in. Becareful with decompression plates mine was shit hence why I went back tot he thickest HG ran alot better

The trouble with changeing the bottom end is the rents will notice im pulling the engine out and windge, were as if im doing the rings ill just say im serviceing it lol.
apart from rings, cam belt, head set and sealent from the sump what else would i need.
what problems did you have with the de com plate
