Maybe someone can help with this, banging my head.
The 1995 525i m50 engine does not have the PCV, correct?
I am havin aweful time trying locate my Crankcase venting issue.
the CVV on th valve cover is a simple seperator.
hoses replaced going to the icv.
It is/has positive pressure because i replaced the valve cover because of a leak right over the exhaust manifold and was killing me in the cabin, now it seams that same area has a leak again because of the non vented pressure.
I have not checked the ICV or taken the intake mani off as of yet to get to that. Guess what i am asking is it would be so simple if there was a PCV on this engine to replace but there is not.
readings are for O2 replacement, could this effect the vent issue?
blowin / burning to much oil, cause of the leak.
Other then that car runs very nice.
little help needed,suggestions?
thanks in advance.
just ordered another Valve cover gasket kit, intake gaskets and O2 sensor.
FYI -When warmer weather plus 50 F, not getting as much smoke out exhaust as when it is colder then that and idle is steady.
I have researched
the web here.... cant find one article about the ccv system in the e34/m50 1995 525i
Pcv articles aplenty..... seams this car does not have one.
from what i gather there is no pcv IN THIS VEHILCLE.
ccv hose vent to the icv housing so i have to think if the icv is having issues it would effect my crankcase ventilation?
major crankcase pressure, theres no venting so its blowing pressure out valve cover and oil filter housing. (weakest Points)
smoke out tailpipe
has a Hunting idle? hum...... ICV and housing probably all gunked up.
oil in air box
Is the CCV in front of valve cover on engine have an actual valve? or is it just open? like 6 - 10 bucks to replace. (replaced hoses already)
need photo of the cc vent system...
also cold start issue,
warm weather 50f plus cranks over like a champ...cold then that over night I have to do the peddle to metel technique, till it turns over..
Intake temp control sensor replacment combined with icv cleaning should get me started in the cold...
when i take the intake manifold off will check for all vent hoses to be cleared.
Am I on right track here...?
