i mentioned a weeek or two ago that my engine was making a tapping noise, sounding similar to deisel engines. in my manual it says that replacing lost oil or adjusting the valve lashings can solve the problem. my oil level was as high as it could go safely. i adjusted the valve lashes a couple of days ago. i did everything according to procedure, except that i couldnt rotate the crankshaft ccw, i had to rotate it cw, but i had all of the markings matched up for TDC. now, the noise is louder, and more even. it sounded more irregular before. but its a constant tapping now. my manual also mentions that it could mean that i have worn out valve train parts, or my timing belt could be improperly tensioned. im almost positive that the timing belt was replaced within the last 20000 miles. my parents owned my car before me and they took it to the shop before i bought it from them. it was at like 103000 miles. my mother and i remembering the mechanic changing the belt anyways bc it would need it soon. my dad thinks it was never changed. it doesnt look worn out or old though. anyways, im pretty much just troubleshooting right now. any advice would be appreciated before i have to get it checked out by a prof.

 

I'll copy it to engine tech also. keep an eye out for it there.
