I posted a message a couple of weeks ago about my nephew's '87 240 timing belt problem. I had a chance to work on it yesterday. Several teeth were stripped from the belt. When I tried to turn the cam sprocket, it was stuck until I worked at it for a while. I positioned the 3 sprockets, installed the new timing belt, but wouldn't start (seemed like it was firing, but wouldn't start), changed plugs & put timing light on #1 plug wire. Timing light fires, so seems like it's getting spark. Removed and looked at new plugs, they appear moist, so I think they're getting fuel. Checked the oil and found it to be off the dipstick, added 3 quarts and it was still low. Checked the compression and all cylinders were around 30 lb. Added some oil to cylinder #1 and rechecked the compression, it came up to around 40 lb. Is the engine toast? Would the low compression keep it from starting (temp was around 20F)? Is the low compression a result of lubricant depravation? Thanks for your help.
