Junkies 97 RS Rebuild(1st timer!)

[boostjunkie333]

Ok, well there's one corner that looks like it doesn't have any of them at all. But it also looks like it's not supposed to so..

Guess i'm fine there.

My next question is, I took the cam shafts out of the head with the sprockets still on them. I changed one oil seal pretty easily. The other shaft, I believe the exhaust one, has this magnetic black cap on the end of it, preventing me from being able to slide the oil seal over it. I need to take the sprocket off, but how do I do this without it being in the head? Suggestions are welcome, as I can't seem to get a good enough grip on it to break the bolt loose. Should I reinstall it in the head with the caps just long enough to break the bolt loose?

Have someone hold the cam while you use a breaker bar. I'm sure there's other ways but that's what I did. You can reinstall it back in, but you'll mostly just turn it, even with the springs applying pressure.

[SilvrEclipse]

Yea you have to hold the gear while you turn the bolt. You may could put the side of the gear in a vice and turn the bolt. Just dont crush it.

Ok, ill try and see if I can figure out something without damaging anything.

Update:

Should be getting my motor and rods and rings back all this week on diff. days. Should be assembling the motor this weekend. Will post if I run into problems, but I dont think I should bc I've already found out everything I didn't understand ahead of time, and I've walked through all the steps, so I should be good.

[boostjunkie333]

Held the camshaft in my hands real tight and had someone use an air wrench to pop the bolt loose. Came pretty easily. Got my motor back and all that. Balanced rotating assembly, and now I gotta wait for the rings to come in tom. So im going to go ahead tonight and get the crank in the block at least.


Does anybody know, when the rods go on the crank, which way to the bearing locks need to be facing? I feel like it needs to be a certain way..

[boostjunkie333]

Ok so the main bearings laid into the block fine and lined up right. I laid the crank into place, and laid some pieces of plastigauge on the mains journals. Got ready to put the bearings into the bed plate, and they dont fit right. They are the right size, but the little grooves dont line up, like on the bed plate the notch is on the left, and on the bearings the notch is on the right side. Dunno how this happened...guess ill go back to the machine shop.

[david-b]

Are you sure you were using the right bearings for that? As long as you got 420a bearings, they'll line up right. I understand what you're talking about with the tabs not being the right way but don't understand why.

Amnd the bedplate doesn't have a gasket. It has a very fine crosshatching on it so when it gets torqued down to the block it forms a perfect seal. But MAKE SURE that O-ring is between the 2 by the oil filter.

[SilvrEclipse]

This is a common problem. There is actually 2 different 420a blocks, and thats where the bearing problem comes in. I had the same issue, its not a big deal just get a dremal and grind out the area for the bearing tab to sit in

[boostjunkie333]

That's actually exactly what I did, was grind tiny notches in the bedplate journals so theyd fit in. Problem solved.


Dave, make sure the o-rings are where now? Im not sure I understand where your talking about

[david-b]

I'll try to take a pic for you when I go to the garage where my spare block is. It goes between the bedplate and the block. It's the only place that looks like something can go. Right by the oil filter. I believe its the red o-ring that goes there.

[boostjunkie333]

Hey which way do the rod journal locks face? front of the engine?

[boostjunkie333]

And also, I can re use my arp head bolts right? I read somewhere, although I may have read it wrong, that you can't re-use them. Is that bs?

[david-b]

You can resuse them forever

[boostjunkie333]

rods locks towards the exhaust sidE?
