Keep in mind I am not the most knowledgable with this stuff.
Last weekend I went to adjust my valves because they seemed to have a little bit of excessive noise. They almost seem louder now after adjusting. The #11 valve wasn't even closing all of the way before adjustments. I had a hard time seeing inside of the #1 cylinder to check for TDC, so I used the even harder to find TDC line on the flywhel(covered in rust). Is this line even accurate? It seems like a 36 year old timing chain might stretch a bit. Do most people just use this line for determining TDC, or is there a better way? Also, my old FSM (printed in 1967, so probably for f135, I have an f145) says adjust the intake valves to 0.010", while the tech links say 0.008". Which one, does that 0.002" really make a difference? I used 0.008" for valve lash.
Now for checking timing, my fsm says set the octane adjuster to 0 before checking the timing, but people here say undo the vacuum advance line. So does it matter which one I do for checking the timing? If disconnecting the vac line, do I plug it or check timing with a vac leak?
Thanks, just trying to use the tiny bit of free time I can round up to get the pig running a little better for the 5 hour drive to pismo. Seems to be running a little off from ignition.
