Hello all - Not much of a mechanic here. Just would like my 88 RX-7 conv with 13-B non turbo engine to keep running well. Anyway, here's my problem. I just had the oil changed 100 miles ago and now (at 118K miles) the engine has a knock in it. Not a small little ping but a deep knock that increases in intensity as the rpm's increase. That sounds very ominous to me. Any advice? Thanks!

 

first stop smoking crack, and get some new pistons. :O)

 

i think you might have spun a bearing and you might need a rebuild now..

it all worked out fine. it was just a belt that was tearing up. car runs great again.
