I had my engine ported and rebuilt. We changed corner seals and ALL gaskets. Now its smoking a lot especially when I start the engine and consumes oil??!! Whats wrong? Everything else is ok. The guy who rebuilt my engine put a castrol 5W60 race oil I think. Could the oil cause the smoke (too low viscosity)? Should I worry or is this "normal". Should I change the oil?

 

geeze i wish i could help you. Icemark?

 

How many miles on the engine? Completely normal for fresh rebuilds for a few hundred miles....

HOWEVER, if someone ported more then a few MM towards the inside of the housing, they have cut into the oil seal area...That would explain your problem.

 

I'm with Aaron, sounds like who ever ported your engine may have touched into the area were the oil control ring travels. You can safely run heavier oil, 20w-50 (as long as it is warm outside), that may help a little bit.

 

I´ve driven about 300-400 miles. I dont think I have to worry about oil seal area because this is actually 2nd time we agglomerate engine after porting (first time was unlucky for me..) and we didnt have this problem then. How many miles should I drive until I can go to dyno? (boost pressure 4.5psi at the moment)

 

wait atleast until you have 1000 miles on the rebuild. Also I wouldnt spend any money on the dyno until you are sure your engine isnt FUBAR.

 

Sorry for my stupidity but what does FUBAR means?

 

f#$%ed up beyond all all reqognition

 

Just a thought but the turbo could be burning the oil as well. What is the condition of your turbo (miles, shft play, etc.)? Aron is right consumption of oil is normal for a new re-build. Give it 500-1000 and things should settle down.

Turbo is a brand new To4b 60-1 So I dont think its the turbo that smokes (hopefully). I have ~500miles on a rebuild. Ill change oil next week to little thicker maybe 0W40 or what do you guys recommend?
