Rich or overloading problem.

Ok so I traded my brother my hyundai accent for his BP swapped festiva. As of right now the car runs super great. We swapped a b8 block in for lower compression for a turbo setup. We need to fabricate a charge pipe in order to turbo it. basically what Im getting to is, could the low compression block be the reason for the overloading and smoking under a load?

When you first fire up the car it doesnt ploom out blue smoke untill you try to take off. once you get going it clears up. It stays clear unless you engine brake a good bit or smash on it revving it tight. A few people told me that it couldnt be valves seal because it would smoke all the time, even at idle. That sounds logical, i mean my bro replaced them when he built the engine.

Im thinking either the low compression, or the fuel pressure regulator.

Also I noticed yester day that the plug on the CTS is really loose. I do have a check engine light. Could a bad CTS cause the computer to pull timing and richen the mixture? It also has a slight pop when engine braking thats why I assumed it was overloading.

Wow nobody has any idea? The engine is N/A right now.

Since no one else had said anything I will at least try. From what I know blue smoke is oil. Check your spark plugs for oil.

I changed the plugs today and they were alittle white frosted. Actually it was more like tan colored, but they wasn't coated in oil or anything.

Usually when you let off the gas and then punch it again and get smoke, it is worn or broken rings. Do a compression check and see what you get. Advanced timing can cause it to smoke as you describe, but if you have a muffler on the car, you should be able to hear it "pinging" really bad.

Its got a straight pipe exhaust on it. The block we used to run when it was a B8 and there wasn't any problems. I haven't noticed any pinging. The car runs super great, its just a minor smoke problem. It doesnt cause a smoke screen or anything just a puff of smoke here and there. I did notice this morning when I started it to warm it up it was ruff idling and then I tried to take off and it was choking and gagging untill I revved it and cleared it up, then the puff of smoke came then cleared up and everything was fine.

Would posting a video help?

So u used the pistons and rings from the b8 right? How do you know the rings are not stuck/shot? And check the breather system/pcv, you might just be drawing the oil out of it.
Make sure your fpr is not ruptured taking gas in through that vacuum line.

Yes we used the whole B8 block with a bp head. We were running the B8 days before the swap and it didn't smoke at all so I know the internals are good.

Ill check into the pcv and fpr. Im leaning more towards the fpr.
