I just rebuilt my cylinder head and reinstalled it. once i cranked it up the lifters imediately started making a loud rattling noise. Normally this is due to lack of oil. I checked the dipstick and oil level is perfect. I took it to a mechanic and he said the oil pump is building the right amount of pressure at the oil pressure sensor, but it isn't making it up to the cylinder head. He recommended adding 1/2 qrt ATF and driving it for a little bit, so i did and it is still just as lound. I bought some Gunk Oil Flush and the noise is still there.

How can I clean out my oil passages without taking the entire cylinder head off again????? B/c That was a huge pain in the ***!

Please help me here. Thanks in advance,
