Valves too far in advance or too far retarded?
I know that this is a Cadallac forum and I use it for my 1992 Seville, BUT, I have an urgent problem with my Honda. Trying to get the camshaft syncronized with the crankshaft. You guys are great with engines and the same principles should apply to my problem. My timing belt broke on my 1989 Accord SEI. I guess it's a two liter fuel
injected. I managed to get it apart and get the new belt on. I got lucky and
didn't have any bent valves. The problem is figuring out where TDC is, so as
to be able to synchronize the cam and crank shafts. I have three books and
none of them show what the actual marks look like. Looking through the
little peep hole at them, I can see on the advanced side about three hash
marks, one of them red. Then as you go to the retard side there is a (0)
with no hash mark at all and then farther over to the retard side is another
mark or so. Why in hell can't they just have TDC and a mark next to it? If
it wasn't a solo job I guess I could try the stick in the spark plug hole to
find TDC. I've never done that and am a little afraid of crunching it in the
Anywhoooo ... I got it running, set the timing and took it for a drive
around the block and thought it was OK. I let my son drive it 90 miles to
school and back this morning. He said that it didn't run right, so I tried
it out again. It runs like it's way under powered and has a bogging down
sound when you accelerate, as well as pinging. I guess I'm probably a tooth
off one way or the other. Any ideas or thoughts on this? Which way too far is it,
and am I gonna burn the valves up if I let him drive it this way again? Thanks in advance, for any and all
responses. And I appologize for using this forum but I have to get it running quickly and the Honda forum is pretty dead. Thanks again.

Re: Valves too far in advance or too far retarded?
If there is no help here, there must be a Honda forum with some real Honda experts. A factory service manual is the best way to work on any car. Haynes and Chiltons are minimal help. I wonder if it may have a slightly bent valve. You might want to check the compression just to see what it is. If the cam itiming is off a little the compression might be low too. I don't know many vehicles that will run being a tooth off but I'm sure it's possible with some cars. Good luck
