Last ran the zed 3 months ago.

Cranked it over today and a sound you don't want to hear was heard....clank clunk clank.

Took off the rocker cover and 3 lash pads are stray. Yep, just siting about out of their correct position.

Looks like 3 valves stayed in their last static position (open or partially open) and decided not to move.

I suspect the pistons have slammed into the valves and knocked the lash pads off.

Probably got 3 bent valve stems now and maybe a notch or 2 in the pistons.

 

I have another L20A in the shed. Came out of a R30 Skyline (I think).

Has turbo, where as the one in the zed now is efi without turbo.

 

Is now the time to change?

Remove head, then assess.

Remove head, then assess.

Great advice, and doesn't take too long.
Any other approach is just guesswork.
