Question on Rod Bearings

[Crizcocane]

Ive purchased rod bearings off sho source and was planning to have my mechanic replace them for me. I try to stay away from the insides of engines.. After lots of reading on here I understand they usually need replaced on high mileage SHOs. Mine has 250k+ My mechanic warned that engines will often fail after just replacing rod bearings as not other internals. However I don't have the money to do a big engine job. So what I'm asking is it safe for me to go ahead with the rod bearings and not have to worry about the rest of the engine? She runs like a champ now. It seems many of us on here have done just bearings with no problems but I have no idea what else they have done internally. Thanks for any advice!

You’re safe. We do rod bearings as a maintenance item, preventive maintenance.

Get another mechanic, he's an idiot! The only way the engine shytes the bed after a rod bearing change is if the "mechanic" screws up the job.

If you don't know the history of the car, and especially if it's an MTX, get them replaced as preventative maintenance.

My original 89, which I drove hard for 182k miles, but didn't lug, had the pan dropped by the next owner at 200k for an oil leak. Bearings were still good, with no copper showing. I later had an 80k mile 95 MTX, with a questionable history, which started ticking, and the rod bearings were toast. YMMV.

This ^^^^^^^

Your mechanic has very unusual theories; very, very, very, unusual theories.

Thanks for that information I'm gonna to a shop my racing buddy's go to for their engine work. Not gonna take the cheaper risk with the engine at stake...

Just know that you can do the job with the engine in the car by dropping the y-pipe and oil pan. So you will need oil pan seals (they only go on the ends) with rtv and probably a graphite donut looking gasket to seal the y-pipe to the catback exhaust.
