Burt, I had to replace the seals on an 89 Suburban a few years ago, and found a brass fitting that I could use in the spark plug hole to pressurize the cylinder. PLEASE NOTE: It also can push the piston low enough in the cylinder that when pressure is released, the valve can drop through. That's never good. I spent some time considering all the worry with clearance between piston and valve at TDC when things go wrong. If the valve is within a mm or so of the piston, where can it go? So I used a special tool (number 2 lead, eraser end down) to ensure I had close to top dead center, and quit worrying about the valves getting away. For me it was much easier than trying to keep the engine pressurized. I had no problems with remaining seals. The valve spring compressor is one of the most underpriced tools available. Buy or rent a good one if you do the seals. Good luck.

Have any of the Imperial Club members had success with these techniques - or any other tricks that I don't know about.? ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
