What's up HT! I picked up this swap an threw it in a shell I'm building. An I fired it up an I'm getting this crazy rattle / valve noise in the head I believe. A friend told me it might be bad lost motion assembly.. Any input or ways to see how I can check possibilities to find the problem would be appreciated as I'm almost done with body work an paint. Gotta get this bad boy on the road lol.
I did record videos of the noise best I could. First video is a complete cold start and second is after car is a little warmer.

BTW I did pull the valve cover off an pushed on the lost motion assembly an it didnt stick. That's the only way I know to check them.

 

power loss?

compression test?

sounds like vtec problem...

 

No power loss
Vtec kicks hard
Compression test is next
What should it be at??

 

less than 150 it would be a problem

 

Ok I'll check it after work.
Thanks bro
