valve problems

I pulled of the intake last night and discoverd the cause of my smoking problem. There was puddels of oil on top of all of the intake valves. Witch leads me to belive the machine shop messed up when they did my valve job. Has any one ever had this simular problem or does any one know what they could have done wrong to make the oil puddel on top of the valves like that.

either they forgot the valve stem seals, or *someone* didnt do a good job at cleaning the surfaces of the manifold/block before they installed the manifold......

1.) valve stem seals

2.) machine shop MAY have somehow managed to bore out the valve guides with lapping compound

3.) intake not sealing properly...

my guess would be you messed up the intake install and have a leak. no valve seals wouldn't allow much if any oil to puddle up on top of the valve heads since the valve isn't submerged in oil.

like i said, the machine shop would have had to seriously messed up the valve guides and somehow managed to bore them out almost a quarter of an inch to puddle up.......
