no longer smooth engine
 

i just start my engine ZC sohc vtec same as d16z6

egale Hbeam , vitara and super kit from FJT , acl bearing , block gurde, block work was done to make rods fit, piston to wall 0.004 inch
i start the engine yesterday and i found that it no longer smooth engine and i thought the hi sound came from the head i adjust the lash ( 20 intake valves , 25 for the exhust valves ) but the sound of the engine still not smooth. is that natural ? and idea will be great

Re: no longer smooth engine
 

Do you mean the engine SOUNDS noisy, or that it RUNS rough?

Re: no longer smooth engine
 

wow i hope your not from an english speaking country. well if its not running smoothly go through all the normal checks, compression first to make sure everything is good. basically start over and try to locate whats bad. some more info would have helped a lot more.

.004 will make your ---- sound like a diesel no dought
Its the story of a built engine...

Re: no longer smooth engine
 

Diesel noises ftw.

more info.

got to do what you got to do. O0
.003 or .0035 would have been my choice.

Re: no longer smooth engine
 

.003-.0035 is a bad idea for 400 whp. All the big power boys are running .006+ with years reliability.

Re: no longer smooth engine
 

.003-.0035 is too tight? my SRPs recommend .002-.0025....is that no good?
