Got an 1989 CRX Si. Seafoamed the intake manifold/combustion chamber and now it makes a loud knocking noise. Possibly a valve train problem, im not sure, tried diagnosing it but to no avail, i can't rule out the problem... just a loud tapping/knocking around the top-end. And the clutch pedal also vibrates when depressed half way which didnt happen before the 'seafoam process'. Anyways, i'm looking for a new engine preferably not a d16a6 motor. Maybe a step up, like a b18a1 motor. I need a thorough parts list and walkthough guide, not a "USE SEARCH BUTTON" or "GOOGLE THIS AND THAT" bullshit... I need to find all the information all from one place without looking at 2, 3, 4 sources for information, since it gets a bit confusing. I've been reading the forums a bit, and it seems like the 90-91 b18s are the easiest to swap with minimal wiring. So to my understanding these parts would be required: D16a6 parts used: Distributor Harness ECU B18a1 parts used: engine transmission axles Misc. parts used: engine mounts is this correct? also can i fabricate the mounts? do i have to pound the engine bay by the shock tower? swapping pulleys? or cables? etc.......thx in advance!
