The FSM is almost useless for instructions on checking the timing. How do you guys do it usually? I Can't really see much of anything. Do you remove the shroud and fan or something?

Most people follow the FSM. You gotta take the valve cover off if you just want to take a peek.

the timing marks are on the Crank pulley aren't they? Why would you need to remove the valve cover unless the timing chain skipped a tooth which is not the case for me.

i can't believe nobody has checked their timing here before.

best thing is have car running and get a stethoscope and listen to the chain for slapping sound I changed mine at 140k.

if you are just trying to adjust your timing then loosen the two bolts on either side of your distributor and use a timing light and aim it at the marks on the crank pulley. If you don't have a timing light then just adjust the distributor back and forth until it runs good. Check your throttle response while doing this so you don't have hesitation.

Thanks edward for actually reading my post, I feel like the other two posters are robots that pick up on keywords and spit out generic answers. I didn't once mention anything about timing chain noise in this post.

Anyhow, I'm having a hard time seeing the marks on the crank pulley (tight space) and was wondering how you guys go about it when you check your own timing. I've checked timing on lots of cars before, I just can't figure out an easy way to get a good view of the marks on this one.

it would be on the driver side of your engine. there is a metal pointer that over hangs your pulley sligthly. it is probably very dirty and hard to see like most of mine were. you should be able to just peer down and see it. if not just do it the shade tree mechanic way and adjust it by sound and rpm level. 240's should idle around 700 rpm's stock.

I usually take some brakekleen and spray around timingmark to clean it up real good then once I find the mark on the pulley take some liquid paper and put ot on the mark on the pulley so when you use the timing light it will be easily seen. Then just losen bolts on the distributor and adjust the timing with light.

clean it up as posted earlier, paint the timing mark on the pulley white so you can see it, then use a timing light to set it to the fsm specs...

you wont need to remove anything to see the timing marks on the crank. You wont have much of a view but you can see it.
