Well the Shaggy-mobile has been down since just after C-mas. (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)
It seems to sound like a compression leak to me. The sound started off quite faint but has become louder, kind of a "huffing" sound from the engine. It starts ok, it runs ok, just very anemically (no power), but still seems smooth, both running and idling. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) BTW, I am paying close attention to the following thread- Compression Testing (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) The Shaggster is going to lash the valves this evening as to see what is up, then he will try to operate it again and if it does not operate well, he will then conduct a compression test. (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) Does that sound right? Anybody want to register any experienced or educated guesses as to this latest malady? The engine was out of the car recently, and the valves we adjusted by the Shaggy MANY times. Wish the lad luck, I am concerned he is gonna need it......

John, I think when I had to do this before, I put one of the bellhousing bolts in the case and used a crowbar or old screwdriver to lock the flywheel leveraged against the bolt. Kinda the wrong way to do it, but it works. Do you have an air compressor? An impact will break those too.
Let me know if I can help. Also before you get the flywheel off, you should turn that motor through and see what the stroke is. Stick a straw or tie-wrap in the spark plug hole. We probably should have done this before Jim left with the motor. |
