Re: 22nd and 23rd Series Suffix information

I'm glad this helped. My engine code starts with H. Everyone keeps telling me that means I have Hydraulic lifters. Not so. All 23rd series engines started with H. The additional suffix codes are after the numbers. Just like all 22nd Series engines started with G, then the numbers, then any additional suffix codes. If I did have hydraulic lifters; at the end of the numbers there would be an (F). At least that's what my research shows.
