hey I'm going to be putting a new set of rod brearings and crank bearings in my 97 camaro. can i do this just by jacking up the engine? does anyone have any pointers for me. Also what brand of brearing would you run. a part number from summit would help alot. Thanks

 

pull motor, drop off at experienced machine shop...

Technically yes you could drop the pan and do it, but chances are it would only last a few hundred miles. If the bearings need replaced, chances are something caused it and their is also damage to the crank journals so the only way to do it right it drop it out.

 

haha that would be nice. Ive built plenty of motors so i can do the work. i haven't spun a bearing or anything yet its just my oil pressure is low and i have 150k on the motor. so basicly i just want to just put new bearings in while i save to build a forged motor. Im on a tight buget now.

 

so I can just undo my motor mounts and lift it enough to pull the pan out? what bearing would you run in a lt1. Ive always liked clevite

 

what is your oil pressures? i have 174,000 on clock and still haul'n.
you cant do cam bearings with motor in car, what about those?..
...cam bearings can also go causing oiling issues.....
might just need to try a diff oil and save yer money for that professionally built forged motor. your gonna think OH ****! when you a.(drop a piston) b.(dont fix the problem) or c.(cant figure out why the oil pump wont prime next.......my 2cent.

 

I have always had good luck with Clevite as well.

I'm not sure but to get the pan off and bearings in I think it might be easier to just pull the motor...and if the motor comes out then you might as well hone and re ring it.

A friend has it down to ~2.5 hrs to take the motor out the bottom of a Camaro and I definately do not envy you doing the bearings with the motor in the car.

IF you insist on a minimum 'fix' I would definately do a new oil pump along with the new bearings!

Good luck

 

my oil pressure at idle is around 5 psi and 25 when im driving. my engine is quite and the lifters are pumped up (not making any noise) so im thinking i will try the cheapest thing posable right now. last time a changed my oil there was metal shavings on my drain plug. if the main, rod and new oil pump dont fix it then i will be pulling the motor. whats done to your car? whats your oil pressure at?

 

Thank you this is just a minimum fix for about 6 months tops then im going forged all the way. its just to get me by cuz right now its my only car. so i daily drive it 50 miles a day.

 

have you really thought this through or are just screwing with us?
1. yes you can undo the mounts to lift the motor to remove the pan
2. what are you going to do about the engine cradle being in the way?
3. did you think about removing the transmission and the timing set to get to the crank bearings?
4. how do you plan on installing new bearings while balancing everything else from upside down?

 

so how do you expect to install main bearings with the crank in?

 

WHAT oil are you running?
what are you basing your pressure from? dash gauge? mechanical gauge? ...try a heavier oil and a mechanical gauge before tearing up your motor

 

lol your right. do you guys know if a right up on pulling the motor from the bottom or is it pretty cut and dry? im running moble one 20w40 and i checked it with a mechanical gauge first.

 

omg, the questions asked on the lt1 forum make me

 

^^^ lol whats easier on these cars out the bottom or out the top?

 

I pull my from the top... its personal choice. What do you want to do?

 

i would rather pull it from the top. i have to pull the radiator and the intake manifold to do this right?

 

yes.. its very easy to disassemble these motors including anything in the engine bay.

 

ok thanks jay

 

Bottom. Far easier.
