You might need a valve job if it's still making noise.

before i did the valves they were not as loud as they are now,
i made the loser, im sure the intake was .003. i changed it to .005. im not to sure about what the exhaust was before i did them. so should i tighten the up more than they are now? something like intake .003 and exhaust .006?

Factory spec for the B18B and B20B/Z is:

Intake: 0.003"-0.005"
Exhaust: 0.006"-0.008"

You adjusted one of them too tight and its not closing all the way. The ticking sound is likely the valve guides being worn and allowing the valves to wiggle just a bit side to side.

thats what i thought, so i did them again this morning and now they are super quiet.......................but i took the car out tonight and after 10mins of ridin they started to get loud again. so i went to my boys house and let the car sit for about 4 hours and did them again, now they r quiet again. i drove they car home. its like an 20-25min ride and they r good know. anybody know what i did wrong???

youdontknowmeeither

my guess is that the first few times you tried the engine wasn't cold. so your valves weren't within tolerance the first few times and the's why they were loud.

the car stays outside not in a garage, when i did the valves it was the next morning. i let the car sit overnight. and its been pretty cold outside lately. but im gona take the car out today and see if they get loud again
thanks everybody for your help, if anybody else has any ideals of what it could be just let me know.

Im assuming you are rotating the engine for each cylinder correct? Are you tightening them down to spec?

yeah. i did the #1 cylinder at TDC with the cam marks or holes in the cams facing up. then for the #3 i went 180 degrees counterclock wise. the marks were facing the exhaust. i did the same for the #4 and the marks were facing down. then i did the #2 the same and the marks were facing the intake. i just went outside and they were still quiet so ill see if they stay quiet tonight
oh yeah i notice i had a fuel leak from the injectors so i just changed the o rings and stopped the leak.
