This was the only problem with the block. No shops would weld it in the car so i took the whole motor apart. Now that the whole motor is out i just want to change the necesary internals. I'm also going to a S/C setup.

 

First off what are your power goals. 2nd is if you are gona replace all the componets with oem parts why wouldnt you do something aftermarket. You can go with a set of rods and pistons and play with compression if you are going FI. First tell us what you final goal is and then we can tell you if its worth playing around inside the motor. If you have the money to spend, send me your short block and I will have ERL Sleeve it and install new componets of your choice. Then you can start out with a good solid motor ready to throw whatever you want at it. Otherwise fix your problem put the motor back together and get back on the road.

 

I want to stay stock with the neccesary mods to with stand the s/c setup. As far as i know i will have to change the bearings and pistons rings. Maybe the piston and rods depending on there condition.

 

I would of got someone with an aluminum tig to weld that piece back on, retap the hole or helicoil it.... sounds like you went through alot of work for something that isn't that serious.

 

He may have gotten someone to weld it, but he'd be hard pressed to find someone that would be willing to stand behind his work, welding an oil port on an engine in close proximity to combustible gases. If the welder was properly trained, he wouldn't do it.

Besides - it would be hard to get a clean weld, given its location in the engine bay. You just can't "weld the piece back on". You can't have any remaining fractured surface left because it will act as a stress riser, causing it to crack off again. If the weld failed and resulted in a blown engine, who would be responsible?

And if someone were to drill and tap the hole, some of the turnings would end up in the galleries. And since this port is located post-filter (the oil passes through the filter before coming to this port), these turnings could end up at the bearings and plugging oil ports.

 

Yeah, he's doing it the right way. Anything else is 1/2 assed. I know a guy who had to helicoil up a single bolt in the head, he wasn't careful, got shavings in the motor and F'd his engine up. I can't imagine welding, drilling and taping and not getting shavings all over the place.

 

Block is at the shop right now

 

Looking at the parts the crank, pistons, and rods are in good conditon. piston has some buildup what do i clean it with? talked to the guy at the machine shop and he recconded i change my bearings. should i do it? also what are the procedure for that b/c of new bearings? I know i will need new piston rings but where do i order them and what size do i get?

 

Your not doing this by yourself are you
