Thread: Im so pissed

u are building a motor with no fsm big mistake since its the first time.

i have the specs.just to confirm

Ouch i made that mistake once with a set of s4's. That was an expensive mistake and will never mix up cam caps again, or improperly tighten them. I mixed up the cam caps and used a set from a different head and not the ones for the head i was working on.

There are FSM's available around. Just look for them.

bad idea you always wanna lay the cams in there to the point there is the least tension. If the bolts feel like they are getting hard to turn before the cap is all the way seated then back them off slowly and try again. But if you do it correcty and tighten the bolts slowly starting at the back end of the engine (the #4 piston area) then you will be good. Once caps are seated torque them down to spec and take a wrench and turn them slightly by hand to make sure they move freely. Then put on and set your cam gears into position and tighten those down.

It isnt a hard job and ive done soo many of them ints not even funny and i have yet to ever break a camshaft doing them.

Good luck on the next time around and definetly get an fsm, i have the procedure memorized since doing it soo many times.

You might want to re-memorize that procedure. You don't start at cylinder #4. Not for loosening. Not for tightening. Pretty sure it's all the way on the other side where you start, and then you go from the middle outward after that.

I did mine the other day and was very careful because I knew they were easy to break. Sorry to hear about your misfortune man. I feel for you.

For reference here's the section of the FSM you need: http://www.nicoclub.com/FSM/Sentra/1994_Sentra/em.pdf

And here's the directory with the entire manual:

ive always started at the #4 side, the #4 side of the cam is the part that is always sticking up higher while the front caps are almost all the way seated and the front of the cam is almost all the way seated.

Here is how i do it. I install the cam to where the least tension will be put on it which is almost in the tdc position of 10 and 12 but slightly off. I install the caps and tighten the bolts by finger until the bolt heads are touching the caps. Ill start at the #4 and do 1 turn at a time on each bolt and head towards the front of the motor, if it seems like the cap is getting bound then i stop and usually give that cap a 1 turn loosen and it has always unbound itself then start get it back with the others. i do that until the caps are completely seated then i follow the fsm bolt tightening sequence which works from the middle outwards to the edges of the motor.

Ive never broken a cam, warped a cam, broken a cam cap bolt or had one that had problems turning. Matter fact i hardly ever get caps that bind but occasionally they do if the cam isnt perfectly lined up with the cam bores but again a simple loosening of the bolt just slightly will always unbind the cap and seat the cam properly. Again never had a problem, EVER

thanks guys
