Got my pistons in. No knock. I'm happy. Also got my A2 design springs in. And now...

When I start my engine in the morning, there is a knocking sound coming out of my head. I took the cover off and I have seen that 2 lifter are little loose. But all the bolts are fine. After 10 mins. everything is fine. Than I shut the engine for about 30min. and again same thing. Help.

 

Pull out and clean or replace the two lash adjusters that are making noise.

 

I have changed the lash adjusters and still knocking. Is there anything alse I could check?
