Hey guys, as I was doing some cleaning to my D16Y8 engine, I took out some lifters from rocker arm assembly to clean. I guess I put them back the wrong way or something but now, my engine is making a knocking sound. Anyone knows how to adjust those? I can't find it in FAQ or anywhere.

These things under the cover.

 

Valve Lash Adjustment. That's what you need to look up.

 

Thanks. You da man!

 

wait you took part of the valve train apart and mixed parts up? you are supposed to put everything back in the same place it came out of ,everything wears in a certain way if something has always been in a certain location it's worn unique to it's place on the cam, you never mix up parts like this, that's one of the most basic rules of doing engine work,keep everything in order

 

Ah. Valve lash adjustment adjust valves gap right? Not the little cylinders inside the rocker arm assembly?

 

I didn't try to. One of them jumped out. The other 3 stayed the same. And I had the cam at TDC. So, I thought if I line up with the hole on the little cylinder and the whole on the cover, it would be correct. I guess not. Any suggestion?

 

Ok. They are called "Lost Motion Assembly".



Is it possible to adjust them back to spec?

 

Well, good news. I just need to replace new ones. No need adjustments.

Bad news. Knocking happened because I didn't lube them when I put in thinking engine oil will get in there by itself. FML. They are shot now.
