Hey all

Looking for some help, I removed the head off 87 crx si to do valve job. Well its ready to go back on, but i cant figure out which way the marks are to go. There is no UP marked on the cam shaft pulley. I've checked Chilton and Haynes and could not find the info i need. Also, could not find mark on the crank for TDC. With head off i rotated motor to get #1 at tdc and placed a mark on pulley in line with mark for timing on belt cover, this right ? With lines on cam pulley set there are two ways it can go. Can someone tell me which way is right according to valve position ? Any help here would be greatly appreciated.

Thank you

The cam pulley goes on with the keyway up. Line the marks on the cam gear up parallel with the head.

The crankshaft timing belt pulley has a tiny mark that lines up with a small arrow on the block. The arrow is about at the one o'clock position on the block.

Funny, I just installed my head on MY '87 Si this afternoon.

If you install the cam 180 degrees out, it's no big deal, the engine has two #1 TDC per cycle. And since it spins at half the crank speed, it's timed correctly even though you think it isn't. Aas long as you have the cam marks lined up and the crank at TDC, you're fine.
