I have R56 N14 with 90k tuned. I have annoying problem with burning oil and blue smoke coming out from the exhaust at/after idle so badly. Car run fine no CEL no misfire

-New Valve Cover.
-New turbo.
-New oil feed line.
-New oil and filter.
-New vacuum pump.
-No oil leaks.
-New oil filter hosing gasket.

Walnut blasting - Not cleaning yet.
Valve stem seal - Not inspect yet.
Piston rings - Not inspect yet.

**These days the problem getting worse** what else should I go over?

 

Stem seals. My friend had that issue. After stem seals replacement, he burns no more.

 

I 2nd that assessment.

 

I think that too. But mine only smoke when my car already warm up. Not coming out at cold start. Can be oil rings?

 

How hard to replace it not taking to the shop ?

 

Find a local shop that specializes in Heads and have them clean/rebuild it. I have a shop here in Denver that does it for $200 and they prefer to leave the cams in. Some shops may want you to remove the cams.

 

Hi in Denver metro too. What is the shop? And check out MINI5280 Social Hub on facebook for enthusiasts

 

Nice to see another Denver Mini owner.

Pena Cylinder Heads on Cook Street. They do a really good job. I recently took them a N14 head that had cooked on oil and a fair amount of sludge. Got it back and it looked amazing.
