Hi folks. I'm new here and I really got alot of info from these boards. I do have a major problem though. I drive a 90 Legacy wagon with a 2.2 mpfi on a paper route and I just put a new clutch set in new wires and plugs a coolant temp sensor and air filter. Now I find that I have no compression on my #3 cylinder. I've been driving the car on 3 cylinders for the last 3 nights and it runs but rough at idle and no power before about 2500rpms. Anyway I need to know if I can do anything to get this roo to run better for a few more days so I can make enough dough to buy a head. Any thoughts will help. Thanks for your help.

You say it has no compression have you tested it or is it missing on that cylinder? if it was ok before you changed things chances are its something you did or maybe a dud lead or spark plug?

Yeah, replace the plug and wire first, making sure that there is definately spark.

Well the wagon definitely has a burnt exhaust valve. I removed the valve cover and the rocker arm assembly.The valves all bounced when I tapped them so they weren't stuck.So I pulled the plug and put air to the cylinder and the air came out the exhaust pipe meaning exhaust valve.I pulled it all down and it needed a timing belt anyway and the intake looked to have been leaking some too so maybe it was all for the best.The exhaust valve was missing a chunk the size of a pea.I'm putting it back together tomorrow so I'll let ya'll know how it goes.

Someone else here mentioned recently that exhaust valves burn easily in subaru.

 

What is the reason for that?
