After driving for 10 minutes alot of smoke is coming from engine bay, engine oil is being burned on exhaust, it is coming from 02 sensor, ( not from inside of Exhaust ). There was leak spotted on vacum pump, i sealed it with sealant and new o ring. Leak has stoped, but the oil os coming from somewhere else , the camcover seal is also new .

98k miles driven






1.6 petrol non turbo , rolling on 18s ,kw coilovers

 

Well oil leaks run down hill so that mess on your exhaust and sensor are from above. Time to follow the mess up to the source above. I've never owned a non-turbo so I don't know what is above but valve cover gasket comes to mind.

Rims look great on there BTW!

 

Where is spy seal location ?

 

I would wash everything down with someting like spray carb cleaner or brake cleaner & get it dry. Then run it a little. Use a paper towel to find where the highest point of trace oil is. Then you are getting close.

 

Ok, i will wash it from carb cleaner or brake cleaner, and then i will look for leak again .
Another question, i know minis are notorious for oil leaks, which seals are more prone to leak ?
i have changed the vacum pump seal
the cam cover gasket was changed 20000 miles ago ( may be its time for new )
thermostat housing has been changed recently

my all doubts are with oil filter housing gasket

 

I would suspect you oil filter housing or the turbo oil lines. Possibly both. I’d do them both while in there fixing it.

 

Agreed, I was going to suggest the same thing.

 

its non turbo motor

 

I have a non-turbo too. I suggest inspecting the oil filter housing and valve cover gasket. They are the two top offenders. Even thought "cam cover" (I call it valve cover) was replaced does not mean it is not the problem. The thermostat housing work would not affect the oil filter housing unless someone was monkeying around with the wrong thing.

 

is it possible to use silicon ( gasket sealent ) on valve cover? Along with old gasket ? Or i do have to replace it ?
