Hey! I've read some of the posts here regarding this topic but I'm still confused whether I have a Euro R or a Type S engine. I bought a 2nd hand 1996 Accord with a swapped H22 Euro R supposedly but the s/n doesn't match up on the internet.
H22A 4020091 is the s/n on the engine and according to Wikipedia:
H22A-4020001~ is a Type S and;
H22A-4000001~ & H22A-4100001~ are the Euro R.

According to this site H22 – Honda Thomsen (wordpress.com):
same s/n with the Type S but
H22A-5000001~ & H22A-5100001~ are the Euro R.

Also, the s/n doesn't seem consistent. the 91 font doesn't look the same and it seems like it's a little bit deeper.

What to look for aside from Red Valve Cover? because the seller insists it is a Euro R but the s/n says otherwise.


​​​​​​​Thanks!
