TomTIII Posted May 7, 2015 Share Posted May 7, 2015 I parked the car, running fine. Tried to start it a month later, and it backfired and barely ran. Compression check indicated none in #4 & 5. Took off valve cover, and #4 & 5 exhaust valves stuck. Tapped on #4 and it was like driving a big nail... all it did was go further down. Put liberal amounts of penetrating oil and 3 in 1 oil, and tapped the valve retainer, and the valves remained stuck. Put a pry-bar under the upper spring and tapped for over an hour, no motion. No idea why suddenly two valves would be so stuck? Anyone have an idea. Can you remove the head without taking off the radiator (the last time I did a Chev 6 was 1969, on a bare chassis which was easy... this is in a restored car.)Any idea in re best values in parts/sources??Thanks,Tom Link to comment Share on other sites More sharing options...
Rusty_OToole Posted May 9, 2015 Share Posted May 9, 2015 Was it out of commission for a year or more, and did you run it on old gas? Old varnishy gas can gum up rings and valves.You should be able to take the head off without removing the rad. Link to comment Share on other sites More sharing options...
TomTIII Posted May 9, 2015 Author Share Posted May 9, 2015 It was running fine about 4 weeks before this happened. Gas wasn't that old:-( Link to comment Share on other sites More sharing options...
