Timing chain questions 1991 DOHC

[amolao]

Started yesterday, well I couldnt find any tips on things to watch out for, and the FSM is not clear enough. Yes I have done the chain on my SOHC manual trans. succesfully. Well the first thing:How do you keep the cams from turning when taking the chain off??? I guess due to being an auto theres no way to make them stop. I used an impact tool. But when is time to tighten down, what should I do??

Also, after I go to TDC, distributor on cyl 1, top chain and cams align on the right spot and markings, how can I get the bottom chain on the right spots before I take it off and replaced with the new one?? Is not really visible until the take the top chain,etc off...should I just replaced it going by the same orientation before I get the new one on???

sorry about the long post and thanks

I personally don't even worry about any of the timing marks but the cam gears. When you put the lower chain back on, you have to have it around the top gear of that chainset and then you need to bolt it on and there should be enough slack in the chain that you can easily just move the extra links over onto the left side of the motor, (at the crank gear). then put your left side guide back on and then your tensioner. Your cams will automatically turn when taking the chain off because of valvespring tension on i beleive the 4rth cylinder. Just use a cresent wrench when you're putting the top chain back on. Let me know if this helps. Also have you tried to put the car in low gear? If you have to get the pistons back up to TDC just use the crank bolt and a 27 mm socket.
