Should I Replace Cam Bearings and Freeze Plugs On My Build?

I dont really want the added expense, and I dont have the tool to remove and install cam bearings. I can pick one up for about $30, then buy the cam bearings for..hmm. like $20 at the most?.. is it worth $50.... I didnt take the cam out yet (only thing left in the block) but when I do if they look ok should I leave them in there?..

I wonder if my machine shop will want them out for cleaning?..

and for freeze plugs.. if I can pick them up for $20 or less for the set I think it would be a good things to do since it would be a beotch to do in the car. since I have the enine out now. will my machine shop want those out to?.. or is it better to leave the ones in there in since they are not causing problems now?

Thanks

also, I need to pick up the liquids required for engine building. the box that my rods came in says to torque the rod bolts to 40ft lbs using ARP Moly Lube.. Thats like $14 for 1.6oz.. is there a cheaper replacement I can use?..

and I believe I read that you need to coat the head bolts with somehting?.. What?.. and whats a good brand?

Also, can I use threadlocker on anything?

what about breaking in a cam?.. or anything for that mater, should I coat anything with any kind of lube when asmbling?.. and then should I change the oil after the first startup since all that stuff will be in the oil?.. (Is there a way to prime the oil pump?)

If you are taking the block to a machine shop, replacing the cam bearings and freeze plugs shouldn't be an issue for them. Those are two things I would definitely have done.

If the block is cleaned by the machine shop, everything (including cam bearings and freeze plugs) are removed. So, your question is really moot.


From all your basic questions, sounds like you really need to buy a rebuild book.

For me, getting new bearings and freeze plugs on a rebuild is not even a question, I would if I was you, no reason not to really.

if its a hydraulic roller cam there is no break in. just slather it with cam lube when you install it. replacing the cam bearings and any other bearings like bombebomb said shouldn't even be a question. Replace them!!!! i understand money might be tight but cheaping out on little stuff like this will bite you in the *** later. just my .02

Let them buy them, then they are responsible for getting the right ones.

I replaced my cam bearings and core plugs myself at home. It can be done, but you have to make sure you know how to install them properly. But for the cost it would probably be better for a machine shop to do it than a first timer. You're risking a lot more than you would gain and the price will be roughly the same.

As far as the assembly lube, you can technically make some using half straight 30w oil and half lucas oil treatment. Your torque readings will be about the same. However, assembly lube isn't expensive. I would just pick some up. If you are that worried about cost that the price of assembly lube is questioned than you should really think about if you want to do a rebuild in the first place.

I do want to do the rebuild.. the block in already bare. Going to send it in tommorow.

I purchased ARP moly lube for the bolts, and ARP asembly lube, and ARP thread sealer. So I should be good there..

I also ordered core plugs, and cam bearings

Let them do the bearings. For the price of the tool, they can be installed by them. They do go ina specific way as well, so like Rich says, let them be responsible for them.
Don't worry about the cam lube. I will dig around, I am sure I have more than half that bottle left, I'll throw that in as well.

My shop wanted $60 for labor to replace cam bearings. I have done it before in school, I just bought the tool for $36.. I can handle it.
