After all my engine work I start the car up and it smokes blueish white, a ton at WOT. The engine did not smoke before replacing the heads, so Im sure the rings are good. These heads sat for three months before I put them on, could the seals have dried and cracked in that time? After setting the timing and changing to a thicker synthetic oil yesterday and driving around, it stopped smoking. This morning I removed the plenum to raise the fuel pressure and advance the timing, and after putting it all together Im getting the same smoke from my tailpipes. I also noticed that moving the TPS has absolutely NO effect on the idle speed.

Now, before I set the timing I had started the car and got a code 33--after removing the MAF and cleaning it, and all of the connections, this went away. All sensors are plugged in, so I need an answer for a couple of questions.. what could cause blue smoke from the tailpipes, but stop smoking for a day, and start again? Possibly timing related? If the TPS has zero effect on idle speed, is it bad? Thanks guys.

 

I noticed my coolant is low...Is it possible for the coolant to get into the combustion chamber while the engine is running, but not get into the oil? When I changed my oil there was absolutely no coolant in it. Spark plugs are very clean. Im thinking intake manifold leak, sound right?
