First start after engine install problems

[wacko]

So I removed the timing covers and now I cant rotate the engine??? My valves are all out of adjustment. When the engine wouldn't rotate I loosened all the valves off and still no luck.

I had been rotating the engine by hand quite a bit before trying to figure out the timing. I only actually ran the engine for less than a minute. Can having the valves all out of adjustment have caused some damage?

Any suggestions on how to proceed.

[wacko]

Never mind. I had the car in gear!!! Doh!!! It's been a long couple days

You need to pull the engine out, get it back on to your build stand. Stop what you are doing, and walk away for a day or two to clear your mind. You are tired, and you know something is not right. Give yourself a chance to regroup.

Then, read Wayne's book on rebuilding the top end portion of the engine. Especially the section on cam timing and adjusting valves.

You may want someone to look at your engine and make independent observations. Maybe even pull the plugs and get a look at the inside.

There are relatively inexpensive cameras that can look at the head and valves by going through the spark plug hole. Advanced auto has one.

Ok then, maybe leave it in the car. Leaving it in gear would seem like a frozen engine.

But seriously, from some of your questions and comments , it sounds like you need a break and regroup.

Wacko,

Take a break and relax. You have done a good job so far and just need to over come this little obstacle. It is not convenient to do a cam timing with the engine installed in the car and you decide which way to go. For me, I rather do all the cam timing, sprocket alignment, and valve timing with the engine on a test stand. As a matter of fact, I run the engine before putting back in the car. You don't have this luxury at the moment so do what is best for your situation. Keep us posted.

Tony, as I was going to take my chain cover off this afternoon I intended to post the picture of the "930 or dot" at the 12 o'clock position when at Z1 (for
wacko) only to find out that neither of them got the "930 or dot" on them... Any idea why.

The only visible mark is the CAM Drive part # on the passenger side: 901 105 546 02

I thought the keyway was also the top of the cam.

Yes. But once the sprockets are installed, you won't see the groove for the woodruff key.

The cast numbers are also on top for SC, Carrera, and 964 cams I have. So that's maybe another way of identifying the cam orientation if you don't have the 930 or dot marker.

Just to conclude this thread, I pulled the cam chain covers and re-timed the cams. Re-adjusted the valves. Put it back together and it fired right up!!! Thanks everyone for the help.

Right on, I was able to see one number on each side and they are at 12 O'clock.

Thanks Tony.
