ok guys, i saw the thread about cahin or belt, i have a 1994 sentra se-r, and was wondering how hard it is to change the upper chain, and how long it takes to do, also what about the lower chain ? is that hard to change, ? and which one is more likely to go first?
how hard is it to change?? timing chain

Your gonna have a hell of a time trying to move the dist. by hand, especially on an older engine. Use the starter or a wrench to move the cams.duranged said:
As for the previous question, replacing the chains is a royal PITA. You have to take the head off the block, which is a lot of wrenching. If you are going to replace one, you should do both. It took a friend and I three days to replace the chains and everything that goes with it (ie: head gasket, water pump, thermostat, upper and lower chain tensioners, and general clean-up).
I would recommend picking up a good manual for the GA16DE before doing something this involved. We used the Haynes manual, and it got us through it pretty well.
Finally, for the no-start condition, find out what the engine is missing: spark, compression, or fuel. Hows the distributor cap, rotor, wires, and plugs? A little more info would help diagnose the problem.
First of, if this is an SE-R as you stated, don't go looking for a manual for a GA16DE as that will be of no help to you. 
You have the SR20DE.
Second. It might be easier for you to just buy a low mileage JDM engine and swap it in there. Cheap and has more stock HP than the USDM engine.
Just my thoughts.

LOL, I thought this was in the GA16DE section. My brain's fried, don't listen to anything I said about upper and lower chains. There's only one on the SR20DE.NismoPC said:First of, if this is an SE-R as you stated, don't go looking for a manual for a GA16DE as that will be of no help to you.

Still, if he picked up the manual, it should have both engines in there.

ok, first take the valve cover off, jus follow all the bolts around the valve cover till it's off. Jack up the right side of the car, remove the wheel and expose the crank pulley.
With a breaker bar and a really long extention, put the socket on the Pulley bolt and begin to crank the engine slowly at the crank pulley (have a friend do this part). While he's cranking look at the cams and see what they're doing. Make sure the timing chain is nice and firm around the cam gears, at this point, you can try removing the distributer and see if it's just not catching on the cam notches.

BTW, how are you so positive the distributer isn't moving, have you taken the cap off and checked out the rotor movement? Are you saying it's firing on the same cylinder once per stroke??? Ever consider it to be the coil or something else?
oh and for all those who did not read, this is a 94 sentra se-r, with the twin cam motor, i am just learning about these as i am a firebird, guy, and added this to my small car collection, i also own a 98 durango, a 88 firebird v6, and a 91 firebird formula, and those r both project cars, this nissan is my daily driver as i am giving my missus the durango

Like I said, you need to take the valve cover off and see what's going on in there, maybe the chain somehow fell of the exhaust cam (if that's even possible). You'll get a much better view of things when you are able to look at the chain and cams.
ok guys the verdict is in, i took off the valve cover, cranked the engine over, watched the cam chain move perfectly.... watched the rear camshaft move perfectly... watched the front of the front camshaft move perfectly.... watched the back half of said front camshaft stay perfectly still, hhhhhhhhhmmm. i wonder, OOOOOOOOOHHHHHHHHHHH I GOT IT!!! what is broken front camshaft for 100 alex???? yes i win, the jeopardy challenge!!, but in all seriousness, it came down to a broken front camshaft, so more help guys, which cam is the front, exhuast of intake? and does it really matter when i get one? i assume it does as the front one drives the distributor, but i just want to make sure, as like i said before, i am new to foriegn cars, and especially twin cam cars, p.s, anyone of u got a good used stock cam u want to seel very cheap, i will pay for shipping too???!?!?

The cam closest to the front of the car is the exhaust cam. I would like to see pictures if you got a camera...duranged said:
Check around the classifieds, maybe someone upgraded to performance cams and has some stockers to sell. Try www.sr20forum.com as well, they might have more SR20 stuff around there.

"oh and for all those who did not read, this is a 94 sentra se-r, with the twin cam motor"
just for future reference, dont use this description any longer...they all have twin cam motors (GA16DE=GA:engine series; 16:1.6 liters; D:dual overhead cams; E: Port fuel injection) (SR20DE=SR:engine series; 20:2 liters; D:''; E:'')
Your car is an SE-R, you have the SR20. You should join SR20forum.com, all of the members are SR owners, and can walk you through everything.
good luck with everything!
