So i bought this engine being told it was a d16a6 si swap. And I found it has an oil leak aon the headgasket as well as off timing.
So heres my info to provided anyone who can hrlp me decode it. its a none vtec head its code is a PM9-4 (9/3) I've Googler on d-series.com and other decoding FAQ but none have my code ..

 

afaik it is a non vtec sohc head as found in various non vtec 1.6 and 1,5 engines. from what i can tell the most significant difference is the valve springs.

 

well see I originally thought it was a d15b2 head after finding out it wasn't a d16a6 head.
now I find out it can't be a d15b2 due to it being a year 93' head.
so you or anyone from H-T members can help me if really appreciate it!,,!
