it doesnt come with the cover i think, thats why i m confuse about all this rite now and what does blue top mean?

blue top means the valve cover is blue.

If that f20b was taken from a jdm accord cf4, it should be dohc.

ok, i'll add a pic tomoro

my dad and i did not ask the seller ==
my dad made a decision to buy this because engine running smoothly and silently lol, and we didnt know what engine it is either ==

don't just simply buy without knowing what kind of engine it is, it's like marrying (buying) a Vietnamese wife and the worst outcome will be the wife left suddenly and leaves u with nothing

lol, i am lucky this time ==
will check carefully next time

Looks like a D series?

Not even close to F20B...more like standard PGM-EFi engine to me.
And definitely SOHC.

but isnt it a F20B?
somewhere below the engine says so?

Its an F20B SOHC!
This engine series was used in the CF4, CF5, CF9, CL3 Honda Accord.

150hp/6100rpm
137tq/5000rpm
6400rpm redline
9.5:1 compression ratio
85.0mm bore x 88.0mm stroke

F20B has SOHC n DOHC versions... the one u have is obviously the SOHC version.

anyway, it is true that CR-V also use F-series engine?

ok, thx guys

it is a F20B. the first version from SM/CB Accords

F20B got many type wor..

CRV is B20B and K20A
