valves

[11secty]

is there an easy way to check your valves. i mean i know your probably gonna have to take the valve cover off and check them running but i was wondering if there is a way to do it with the motor not running. i just had my motor completely redone and its either the valves or the injectors are really loud to ... or is it possible since the lifters are new that they are taking a while to pump up assuming we have hydraulic lifters...

i know on small block chevys there is a way to do it but i cant remember that way either

thanks

and oh yeah are my stock injectors suppose to be that loud i mean you can hear them over even the exhaust

Re: valves

the injectors have been known to make a ticking sound, very similar to a lifter. it has a lot to do with how well and how far they are seated into the intake and fuel rail. search for injector noise....there's a lot of info out there.

Re: valves

stock injectors are very loud, there was a tsb from the factory about it. it is possible tat you have a loose rocker causing the rocker/lifter to make noise. check your preloads.

Re: valves

preload thats what they should be set say if i were to turn the motor over by hand and torque them down when they are closed?

Yes you make sure both valves are closed by looking at the rockers and then loosen the set nut the go back down with the nut while you are twisting the pushrod with your fingers and you feel the rod stop turning thats 0 lash. THen thighten the nut down another 1/2 turn or so.

Re: valves

thanks phil and by the way got the chip yesterday put it in today along with the 50 lbers( thats a story in its self) but i like it a lot

quick question though even though the chip itself is on o the led display is what really matters right? and what settings or letters are for race gas?

Re: valves

1/2 turn is stock, lots of aftermarket lifters are 1 turn and some are more. you want the plunger in the lifter to be 1/2way down the travel in the lifter.

Right leave the chip switch on 0. I put a paper in the box that had the timing and fuel settings didnt I?

Re: valves

yeah but i dont know if i start at 0 and the first eight are pump gas or race . i do see that as it goes up it adds more fuel and timing is that when i use race gas say on number 9

Re: valves

For pump gas use the 15 deg timing and with race gas use the 18 deg. The fuel # changes the amount of fuel at WOT. Use a rich setting unless you have a wideband. 0 is leanest and as the #'s go up it adds more fuel. Idle and part throttle will no change.
