Lots of Smoke on Rebuild
 

Hi guys,

I could use a little advice.

I have prob an hour on my rebuild of idling and I get lots of smoke. The build is 13b-rew, BW6266, Stock Ports, Adaptronic ECU, ID1000/ID2000. I kept the OMP and I've added 1 ounce per 2 gallon of premix. (Maybe this is my prob?)

Smoke looks blue and gray to me. What do you guys think?

One curious thing is that if I set the Adaptronic to Adaptive tuning on Map 1, the RPM's jump up to ~3200 and stay. With Adaptive tuning set to off for map 1 it will idle around 1700 rpm at ~110 water temp so that seems about right.

Any suggestions on all the smoke?

Sorry about it being sideways..

Smoking on the first start up is fairly common as far as I'm aware. I wouldn't stress it too much, it may take a little while for all the assembly lube to burn off and all that jazz.

Would you say it would smoke that much even after running for an hour? Maybe i'll take it for a drive and see if it calms down.

Its a PT turbo btw... losing my mind today.

after I put in my pettit motor it smoked for about a week on the first start but slowly stopped smoking after that, well i run high premix so it smokes some

Stock port motor, idling like that?

You may need to restrict oil pressure to the turbo.

Turn the Self tuning off. You should be running in open loop until the motor is broken in. Lower your idle speed mechanically at the throttle body screws down to 1000-1200ish. If its a ball bearing turbo make sure you are using a .035" restrictor, journal bearings usually don't need one. Make sure the turbo is clocked properly ( oil feed on the top at no more than 25degree to center line), make sure you have at least a 1/2 drain with no kinks, or sharp turns. Make sure you're "crank" case vents are properly working. If you have a new exhaust system that can have oil in it which will take some time to burn off. If you are still using the OMP, try a tank without an premix while you break it in( make sure the ECU OMP settings are turned on).

Thanks. Turbo is clocked within 5 degrees and drain has a 'kink free' route. Mid pipe is new. As for the crank case, right now the nipples on the filler neck are open until I put in a catch can. I'll try the other stuff you mentioned. I'm told the PT6266 has internal restrictor. It is a ball bearing.

If its like the Garrett yes it has an internal restrictor, but anything over 60psi of oil pressure requires an external unit also. That is your problem.

Plus one on the oil pressure into turbo. My buddy installed a bb that smoked like described until added feed restrictor.

Update on this.. haven't done much with the car over the summer but I'm jumping back in. I did install an oil pressure regulator onto the oil feed. The car smokes regardless of how much or how little I allow through.

I did realize at one point that my crank case wasn't vented properly so I opened up the top filler neck nipple to the atmosphere to test.

Yesterday evening I let the car idle for a good 15 minutes and the smoking never let up. Last night I decided that I likely installed the oil control ring spring upside down (or something else internally is leaking oil) so I removed the turbo manifold. This morning I cranked the engine with no manifold and it still smokes heavily from the exhaust ports.

Here are pics of the ports. Looks like a lot of oil buildup to me.


At this point, I think its time to pull the engine and check the internals. Any other suggestions before I take the leap?
