    After dropping a valve about 3 weeks ago. i decided to buy a used b20b long block from a place in NJ. for the start of my b20 small turbo project.

    I received in in 3 days and it looks really clean and for some reason it looks to have been taken apart or really well maintained.but that's just a double edge sword

    the good:
    cam caps have honda bond
    rear main seal plate also had HB
    the exhaust and intake ports are clean as fuck only #3 intake is dirty.
    the block looks really clean
    timing belt has a little dirt on it but it looks good
    no rust
    all the bolts were there and not stripped
    all sensors are intact

    i can see clean pistons through the spark plug hole. it looks like a circle inside a circle, ive never seen a piston like that. also the head gasket looks to have been sprayed with copper

    which brings me to my concerns / the bad....

    wouldn't the engine have carbon build up specially on the pistons?

    the cam marks do not line up and the rear black cover is hitting the cam sprockets. one of the spark plugs was also with out a gap, looked like some one pressed it or the piston touched it.

    i am going to change the oil/water pumps and TB from my old engine.
    but i don't know if i should set the timing the way it was or if i should set it at spec?
    if the head was milled because of an over heating then the timing marks would be set up right.

    what would you guys do? :confused::confused::confused:

    Did you find anything 'wrong' with your motor?
