<x-charset iso-8859-1>Gee John... you gotta stop driving like Leon! Seriously, I had this problem... last set of heads. Its cheap quality aftermarket head syndrome... the aluminum they use is too soft... Berg warns of this and reccomends only using the genuine VW heads. My #3 ex tightened up for years... when I did the valve job the seat had sunken in the head and the valve had kinda mushed into the seat.. poor quality valve too. Get a new head... at least on that side, a genuine VW one and Id put genuine VW valves in the other head so long as none of its seats are sinking... its too big a disaster if a valve breaks to mess around. your seat is actually sinking into the head... its not a seat problem but one with the material of the head. Do nothing? well it will probably just keep tightening up till you cant adjust it out anymore. You may burn that valve too but probably not. The seat could come loose but it cant go anywhere. The problem is... cheap valves can break... usually it takes a worn guide though; but there is always some risk with running cheap valves You have a SERIOUS blow by problem at the head seal. with a new engine you should see no carbon outside the combustion chamber and the sealing surface should be uniform silver. Did you lap the cylinders in?? Just like lappin a valve and even more necessary and youll find a machining problem if there is one this way. You sure your case studs arent pullin? be extra anal about things when you slide the head on to make sure you dont get ANY dirt between the cylinder and head... its awful easy to do (ive done it) and can cause sealing problems. Bummer... but your problems are probably confined to your heads. Keith > OK, I am looking for some advice from the experts out there.
