Ok i bought car wrecked slowly rebuilding it. it is a 1997 rs engine has a knock around 3500 rpms but does not make noise when it has a load on it only when slowly reving up to 3500 rpms so i figuered it was main bearings drain oil find bearing material in oil little pieces. so start to tear down to change mains and get to the bed pan and take bolts out and it want come off want even budge so their is still bolts holding it on im guessing but i hav looked every where and do not see any bolts holding it is their some bolts hidden some where i mean dang please help thank you

When i took mine apart o had the same problem. There was a bolt next to where the oil filter goes that i overlooked. Came right off after that.

After removing all of the bedplate bolts, use a rubber mallet and try to loosen the bedplate from the block by smacking it carefully.

thank you very much but i have taken all the bolts off that are shown and still will not come off oh and just so you know i am doing this with the engine still in the car... so do i need to take the pully off to get it off????

i could have sworn you couldnt change the main bearings without removing the crank since the bearings are keyed. and you cant get the crank out without removing the pully, timing sprokett and oil pump. plus you have to undo the crank from the transmission.

if your going through the trouble to get to the main bearings, id have the crank atleast polished back up.
if the mains were in fact the cause then i can bet you that the crank journals have some scuffs, and may possibly ruin the new set your putting in.

I don't think you can remove it with it still in the car - there's front oil pump bolt that run into it so you have to tear the whole front end down

Thank you everybody for your help and sugestions and to clairafy you can take the bedplate off with the engine still in and let me tell you what a b**ch it is go the extra steps and pull the engine trust me its worth the extra time it will save you lots of headachs and loss of hair lol... But i go through all the trouble and guess what the mains are perfectly fine look great so that means it is rod bearings all that work for nothing.... Thank you once agian everybody..
