Does the motor rattle on acceleration? does it only smoke at first start up after sitting for a day or over night? what causes this, is the valve seal could be dried up from heat. oil runs down the valve guild and sits on top of the piston.thats why when you start it up after sitting for a day or over night the oil sitting on the piston burns with the fuel mixture. you can change out the seals with out removing the heads. makes me wounder if the valve guides are worn out to. when you go to change out your seals once the valve spring and seal is off check for play in the valve stem and guide. if its only the seals, make sure you adjust the valves correctly after assembly of the seals.look at the web sight that was suggested on the other post. if you have the tools and knowledge its not a hard job to do.shouldn't take more than 7 to 9 hours. of course this depends on your mechanical expertise .
