Holy smokes

[etriebe]

My Ty is blowing oil smoke all over. I have a new engine with 0 miles on it started it up to break it in and now its smoking. I had the turbo rebuilt awhile ago. I pulled off the exhaust side housing to get coated and I put it back together and found a slight oil leak at the bottom so i removed it again and inspected it. I saw nothing wrong with it so I put it back together and tightened the crap out of the bolts and it didnt leak and then all of the sudden it was pouring smoke, pulled the turbo back off and started it and no oil smoke, just a little rich. Where should I start looking to seal this thing up. It is a non ball bearing innovative T-66. thanks

Re: Holy smokes

New engine? As in complete rebuild? If thats the case, then I wouldn't be concerned yet. Give it some time for break in.

Re: Holy smokes

could it be possible that you either forgot to put in or do not have the right oil feed line restrictor?

also you did prime the oil pump before initial fire up i'm sure, correct?

possibly other than that, that maybe the seals just went shit house in the turbo for some reason. sounds more likely than not that is has to be a turbo issue.

yes it' s a new engine but i still would not tolerate it smoking at all, because it shouldn't have any reason to only smoke with the turbo bolted on

Re: Holy smokes

Need to get this datamaster on it for safe sake just incase it is somthing you can't see.

Re: Holy smokes

if its new as in complete rebuild as asked above i wouldngt worry so much and give it time.. every motor ive ever rebuilt/got rebuilt has alwyas smoked during first few start ups

Re: Holy smokes

I just got a thought as I read your post. Just a couple things to check....
First a few questions:
Do you have a PCV (Positve Crankcase Ventilation) system?
If so do you have both PCV's in place?
If you have both in place are they the correct "E" type (look on the bottom of the PCV Valve itself for the "E"). If they are the wrong type they may be a weaker PCV and letting oil pass thru.
Are they installed with one going to a hose on the back of the throttle body -(this one works when intake sees vacuum) and is there one that goes before the turbo - (this one works when the intake sees boost) ?
If any of these things are messed up it could cause oil to pass and make smoke from the oil passing into your engine or in front of your turbo and into your engine.

One other thing: I would dump the oil and see if the viscosity is gone in the oil. It couldn't hurt anything and it would be good insurance. Fill it back up with fresh oil.
I hope with your rebuild you replaced your radiator and oil lines (radiator has oil cooler built in and particles get stuck in there from the last blown up engine and then when it is reinstalled on the new motor it gets heated up and flows right into your fresh motor screwing things up).

Some things to check anyway...Hope this helps.

Re: Holy smokes

Yep this a total rebuild with new rods, pistons, crank, and block. Maybe I should dump the oil and start it again, New rad and oil lines, and did prime it before i started. The oil line I purchased from RPM and it is not a ball bearing turbo so mike said not to have a restrictor. I will have my lady video tape it and show you.

Re: Holy smokes

Check your plugs. If they are damp or wet with oil then it may be that your rings have not seated or an intake gasket may be leaking. It is common to have the intake gasket leak on rebuilds. They can be finicky. If they leak on the lifter valley side you will see a lot of exhaust oil smoke. If the plugs are dry then it could be turbo related. Make sure your turbo return/drain line is unrestricted. Did you put on a larger than stock turbo feed line? Like a -4 AN line? If so you will need a restrictor. High oil pressure along with high volume can push oil through the turbo seals. If you upgraded to the high pressire/high volume oil pump you may need a restrictor even with the smaller stock oil feed line.

Re: Holy smokes

I pulled the plugs out and they were a little black but not wet. Changed the oil with 30 weight. Here is a video of it. It only smokes after it has been running for awhile.http://www.youtube.com/watch?v=TiwUC2tsrnA Thats nothing yet. It gets pretty bad where you cant even see the truck anymore.

Re: Holy smokes

Just looked at the RPM website and the oil line that I had purchased was a -4an Line. Where can I get a restrictor and how much of one.

Re: Holy smokes

Is it my eyes, or does that look more like steam than smoke? What does it smell like? Does the exhaust drip?

Re: Holy smokes

When I had intake gaskets leaking it smoked more as it warmed up also. Check your intake vac on your Boost/Vac gauge. My vac was running below 10% after it warmed up and strated smoking more. It also started to idle rougher.

It is hard to tell if your smoke is blue enough it be heavy in oil from a lifter valley side intake gasket leak. I almost looks as if you may have a coolant leak from head gasket or intake gasket. How did you install your head gasket and which ones do you use.

How did you install your intake gaskets? Did you silicone the water port areas of your intake gaskets? They can leak water into your intake as well.Check you rear cylinder spark plugs an see if they are wet with water/antifreeze.

If you used antifreeze then you may smell a sweet odor from your exhaust indicating a water leak. If this is a new build you may not have used antifreeze in the initial startup. Most of us only use water in the initial startup/breakin period so that in case of a leak we are not getting antifreeze where it does not belong. In either case look for moisture and water droplets from the exhaust pipe as stated before.

Re: Holy smokes

No water drips out back and it smells like oil. I was thinking the video looks black and white then i realized my Ty is black and white.:rotf: Ok I will check the back plugs tonight. I used the Gasket set I got from RPM and used GM engine sealant on the ends only.
