  • smoking after valve seals

    Okay so i did a complete seal gasket change last week because i was smoking a bit when i first started the car up. I changed all seals accept the piston "O" rings. After i did the valve seals it smokes even more is there a possibility that i didn't put the seals in correctly or i need to change the valves? The valve seals are under warranty so I'm going to replace them if broken and I just bought exhaust valves and intake valves as well to get it all done and out of the way but what could be a cause of the excessive smoking while driving?

    Off hand I'd say you plugged the leaks around the valves so now more is coming out around the rings? I was told white smoke means worn rings.

      Could also be a cracked valve guide. I had this problem once on a Fiat. I ended up with house-sized clouds of smoke out the back end every morning when I started the car.

        blue smoke means rings, white means coolant passing to the combustion chamber. Black smoke means the engine is running too rich.

            I would replace the head gasket first and if the smoke does not go away replace the head. Is there any coolant mixed with the oil. The oil would be a milky white color.

              no the oil is normal and i replaced the head gasket as well as all the other gaskets and seals. so i think i will have to replace the head. Is there any way to replace the valve guide or is it gonna have to be the whole head?

                If it is a valve guide, a machine shop can press out the bad one and press in a new one. In my case with the Fiat (which had an aluminum head on a steel block), it was obvious which cylinder it was in -- that spark plug fouled with wet oil every 100 miles. Besides having to stop to add oil, I had to stop frequently to replace that spark plug. I was driving around with a box of a dozen cleaned-up plugs, replacing that one at the side of the road frequently.

                In the meantime, if you have a "neighbor from hell," I suggest pointing the tail end of your car at his house every night so you can envelope his place in your house-sized cloud every morning.

                  does it happen every time or just when the car is cold? as you accelerate does the smoke increase?

                    ya it happens every time and it doesnt subside as i drive more. it is almost identical symptoms as with alaskafestguys fiat so i am gonna get a new head then rebuild the old one from the ground up with all new guides valves and seals.
