ok, i took my engine apart, sent it to be re sleeved, and i finally got it back, well, i go to check the letter stamped on the block so that i can cross-reference the crank to see what color bearing i need, and, wel, it was a number, not a letter. the number 4 was stamped there. at first glance i thought, oh, it's an "A", but i looked again, yes, it's a number 4. i am confused as hell, i can't figure this one out for the life of me. has anyone else had this problem???

also, i had never actually checked, i always thought that the USDM base Prelude was a BB8 (don't remember where i got that info, it was even used as a reference with my GReddy turbo kit), well, i had never really payed that close attention to my VIN number, but while i was cleaning the block, i noticed that the VIN number said BB6, not BB8. ok, does anyone have a clue which is which for sure???

 

A buddy of mine has a factory service manual for his lude. I will try and look in it to get the answer for you. What engine do you have?

 

i've got the factory manual, it doesn't help, is says i need the letter off the block, not a number

 

where did you look for the letter? on the bottom of the block where the oil pan bolts up? there should be 5 letters there. each one of those letters corresponds with a number stamped on the crankshaft, and that tells you which bearing you need for that journal.

 

NO LETTERS!!!!!!!!! it was just numbers..... 5 stamps, number 4 on each

 

maybe they're all numbers on obd2, or 96-up cars.

 

the B18C5 i tore down last week had letters..... the book even says it should have letters, but mine has numbers

 

very weird.

 

your tellin me
