Smoking while under heavy acceleration?

BOOSTED
I've been noticing that my Ty has been starting to smoke while under heavy acceleration and boosting. A little background, when I bought it it was in DIRE need of a tune-up. It was running pig rich at idle and under light driving To the point where I have a bunch of black spots all over my driveway. Got a brass terminal cap & rotor, Taylor wires, UR6 plugs. Changed the fuel filter, cleaned the K&N, changed the oil and filter with full synthetic and replaced as many vacuum hoses as I could.

The truck runs 10x better, but over the past week, I've been noticing that under moderate to heavy acceleration, even under WOT It starts smoking out the exhaust and it looks blue. I was down about 1/4 quart. It idles like a Volkswagen, the driveway spots are gone and it boosts like a supercharger but its embarrassing to get on it because of the slight trail of smoke it leaves behind while on it.

I'm leaning heavily on oil is somehow getting past the turbo and getting burnt. Is there an easy way to check?

I'm leaning heavily that you've hurt a cylinder or two. Compression check.

could be the turbo:2cents:. Check for oil in the up pipe(accordian hose) and turbine/downpipe. Then x5 on the comp check,.

Bad/leaky seals on turbo? Any oil residue on or around it?

Re: Smoking while under heavy acceleration?

If you hurt a cylinder you would also be smoking and huffing even at idle. If your motor has some miles on it your valve seals are probably shot, your rings are getting worn and your turbo is probably leaking. This stuff shows up under boost.

Do a compression check as previsiously advised. A broken ring land wiill show with low or no compression. If all the cylinders are within a decent compression range to each other then the above seals and rings are just aged. You can also open the cap on your oil fill and if it is showing some pressure and huffing some oil, you can skip the compression test as you probably have a cracked ring land.

Did a compression test, all cylinders within 10% of each other, plugs are a nice light tan. There was a very slight oil residue at the accordion hose. No blowby coming from the oil fill tube with cap off. I check my oil and its THICK, like, '500 mile old oil shouldn't be this thick' thick.

I've been using Mobil 1 5w-30 on everything for years so I have a good idea what it looks like going in, coming out and in between. I had given a "buddy" at a shop down the street 5 quarts of Mobil 1 5w-30 and a K&N filter and he did the oil change while I was at work. Well he did the oil change but I just know he didn't put the oil I gave him. I just bought another case of oil and a new filter, changed it and the trail of smoke is GONE!! Could it be that the oil was just too thick to flow out of the turbo faster than it was going in?
