Im putting my engine back together and im using the same stockpiston setup (pistons and rods). Questions though, should i use the same bolts to put the pistons and stuff back on the crankshaft? I read somwhere that you should buy new ones because there self locking, but should i just put locking adhesive on the bolts or something? Any advice?

Alsoi never read thay you need oil or assembly lube or anything between the rod bearings and piston rod when putting back together, but do you?

do not install the bearings dry!!! buy some assembley lube.....and you can reuse the rod cap bolts......just torque them to 19-24 ft lbs......if a little loctite makes you feel better then use it..I have on some motors and not on some others with no prob done both ways

also lube the cam good to before install.. then prime the oil pump when all back together before start up

ya alright, but i have assembly lube, i just wanst sure if it was needed between them, but i figured it couldn hurt anyway. Thanks for the help. While im at it thought, what would i torque the oil pan bolts to?

I snug the oil pan bolts down...but I believe the spec is 11 to 14 ft lbs....maybe a little less

I'm going to be as positive about my comments as I can and don't intend it to be rude or mean in any way.

I love to hear about someone building their own engine, because so many are afraid of what it takes to do it right and doubt themselves and never attempt it. I always try to encourage others to do their own builds because of how satisfying it is to drive down the road/track in an engine that you built yourself.

That said, I think you were not quite ready to attempt a build by yourself yet.

There are so many things to be aware of and to consider when building an engine and the fact that you had to ask if the rod bearings need lubed before being assembled tells me you lack important information and experience.

I am concerned that other areas of the engine may have been put together incorrectly without you even knowing you did something wrong. I'm worried that you didn't do enough "homework" and research before attempting this project.

Clearances and proper torqueing of bolts is critical as well as when, where, how much and what type of sealant is to be used in certain areas of the build.

I really do hope your engine performs properly and doesn't smoke, leak, etc., but youroriginal questionmakes me think that there are gonna be problems on down the road for your engine.

I wish you well and likeI said at the beginning, this was not meant to be negative in any way.

ya im young and this is definitly a learning motor, but i have people working on this motor with me who know many of the asnwers to the questions i ask, but sometimes i just like to get other advice from otherbuilders, beyond just one to two people. We all have to start learning somehwere and i know how a lot of people on this site are extremely expierenced and know what there doing, so getting info on this site only allows me to learn that much more.

hey man i think its awesome... homework or not you still had the ***** to tear it down and give it a shot... keep asking questions... any little thing you come across, and you'll be fine...

Right way to do it is before you assemble it, take the rods and a set of ARP rod bolts to the machine shop and have them resized. The stock ones are a typical failure place if you have too much fun with the car.

When I did my first motor, I paid an engine building pro 100 bucks to basically stand there and correct me when I was wrong, I was wrong a lot. I doubt the motor would have lasted very long had I not done that. Best 100 I ever spent, I learned a ****load from him in the 3-4 hours we were there.
