Help engine knocking

My engine is knocking and I know it's coming from the head but I have no idea what's wrong

 

97 toyota tacoma

 

Perhaps blown head gasket, or cracked head.

 

Any way you could post a sound byte or video? Anything else you can add to the description? Under what conditions does it knock, or knock the loudest?

 

i replace the head gasket and shaved it.

 

Shaving the head will increase the compression ratio. Not sure exactly how much, but it certainly explains your engine knocking. Try using a higher octane fuel and see what happens.

 

I did and I'm lil more then full oil and for now it stopped but I'm gonna wait till it comes back. Hopefully not but it's Not that bad cause my dads a mech and has a shop... I do, do everything myself.

 

Run a fuel system cleaner to remove carbon deposits. Higher compession means you need higher octane fuel. You may have to buy a case of 104 octane boost.

 

In Hawaii, not much altitude. Shaved head will add to issue with higher compression. First, I would try getting rid of carbon, then if it persists, see about retarding the timing a smidge. A higher octane may be in your future.
