happy new year! sorry for slow reply. finally took off valve cover. that was not fun fighting with wire harness! anyhow seems like i got compression since it spits out of valve stem area. might be bent valve only i hope. was sitting for over five yrs. in same position. must times not good for those valve springs hanging open. see when i get chance. did all or some gn's come with a white paint finish on intake manifold? heat barrier maybe? aloha ron.
Have you done a compression test yet?
