Hi, i have a new engine full port with some upgrades and only run on dyno to set it up, but when is in idle and on gear is smoke some white but is not water it seems some oil and i wish to ask a qustion, how can i know that is the oil pump?? When is on idle the preshure gauge is going on 20 to 90 automaticly, what is please??

 

Welcome to nopistons! Did a shop rebuild it?

 

Yes from dyson rotory but i have see it in the engine is new with that red greys

 

Shops make mistakes too though. If they've torn it down recently I'd go ask them what's going on. A little smoke on cold start is ok, other than that it shouldn't be. The stock oil pressure gauges are faulty at best. If you can acquire an aftermarket gauge that would give you a much more accurate reading. Other than that the gauge shouldn't drop that low unless there's an oil leak. The shop who built it should fix the leak too if that's the case

 

agreed

 

Good luck!
