i just got a 91 crx hf. the tranny is blown and i got another one to put in. however i noticed today when i cranked it that there was a light knock. im pretty sure its coming from the motor and not the tranny. what do i need to do to fix this. new bearings?

 

very likely your case if it's from the motor. for the price of bearings though, a couple more bucks and you could get a si motor, 20-30 more hp and no screwing around w/ innards.

 

yeah, i would suggest looking for an si motor, hf motors arent really worth going to all that hassle

 

well im gonna have a LS/vtec in there in a few months, but i need this. i figure if im going to be changing the tranny, isnt gonna be much more touble, i could just pull the whole motor out and do it all at one time.

 

If it is indeed the bearings then crank will have to spend some time at a machine shop..And is it really worth it to rebuild a motor like that,,that wont even be used soon?? Just buy another sohc motor..There so cheap now days

 

why bother!! just grab another block from the junk their like everywhere, dont even mess with the insides

 

i dunno if it is bearings, i dont know what it is lol.

ive only put together like 3 motors, i dont know much about what cause what :0p

Spun bearings usually come from either over revving the engine..Or not enough lubrication..

 

so what causes a rod knock?
