classic spun bearing sound . Sorry dude

 

just replace the braings and make sure the crank looks okay before it is completly trash and hope for the best..

 

same thing happend to me, im gonna guess rod bearing... get a new crank while your at it, and prolly another set of rods also

 

well there was no spun bearings and the rod bearings where fine but the main bearings shot to hell and i found out what caused the oil pressure problem a bolt on the cam came loose on the oil pressure side but here some pics

 

how bad do the journals look? Hmm, there isnt THAT much metal in the oil pan, you should have seen the pics from my rod bearing problem... just dayuuummm metal everywhere

 

what is weird is i lost the main bearings but not the rod bearings thats the first time i have seen that

 

my old a20 did that, the 2nd one was rod bearings

 

Well i put new main bearings in then i started it up and it ran for about two min's then it seized up . but i am not out i have another b20a but it needs pistons so i am going to take the pistons out of the other b20a that has the bad crank and in the b20a that has the bad pistons so two make one.

 

 

thought you were going forged on this engine?
