Question about 1994 Mazda MX-3
After the car sits more than 6-8 hours when i start it up it runs 45 to 60 seconds with no smoke then after that min it starts boiling oil(blue stinkin) smoke and take 5 or ten mins for it to decrease to nothing then i can drive it with no smoke until it sets over nite or all day at work.if it were valve guide seals i would expect it to smoke at start up not 45 to 60 secs afterwards could this be some thing with the pcv valve or...?
If it's the org. engine it will has over 160,000 miles on it.
It's normal to has valve stem seal/oil seal on the head to leak oil into the cyclinder on high mileage engine.
The smoke you see is the motor oil drop from the valve stem seals. The oil drops land on the top of the cyclinders and it create black smoke at start up.
The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.
The correct fix is to wait until it's time for a head gasket replacement and let the professional CRC/service the head.
Complete head service is the only method to stop this internal oil drip problem.
