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

 

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

 

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.

 

Hany is not a n00b, and you can tell from his sig he's not from an English speaking country. Help our overseas homey out, y0!

 

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

 

Diesel noises ftw.

 

more info.

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

 

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

 

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

 

one man's opinion over 50+ ? ill take the 50+ even if the one man is JD.
