265 V8 cam bearing replacement

[Michael L.]

OK, now I'm considering repairing the cam myself. How hard would it be to remove the cam, take out the rear bearing, cut a groove in the cam ( if not there) ? Could I remove the bearing and drill the holes myself and re-install, or would a new bearing be in order? I ran the engine for about 10 minutes to see if heads would oil up. Since it is just back bearing, taking the cap out would give me access correct?

PS, if driver though Nevada / Utah on I-80, avoid Lonnie Clark at "The Shop" like the plague, he is the so-called rebuilder who refuses to make good on a $2000 rebuild that he screwed up.

You might wont to just pull the engine because you need the trans out of the way to get to the rear cam bearing plug and radiator out to clear the cam out if needed to cut it then the balance then // re-installed hitting it, oil pan off to get the bearing out of the area .

Re: 265 V8 cam bearing replacement

anytime you have a engine rebuilt insist on a dyno run even if it cost you $200/400 because that way there you will have no leaks or any other problems

Clem,
If in this case the top end didn't get oiled, and the motor blew, during a dyno run, I am curious how the engine shop would do anything more/less than they already are (NOT) doing?
Are you suggesting that it would be more their liability if it blew right after the rebuild, assembly and dyno? Than with a rebuild, assembly and the owner just trying to oil her up before starting (or in this case 10 min run)?

Thanks,
David

Very simple. If the engine is blown during a dyno run, the shop is going to have a very difficult time telling the owner it was HIS fault. Plus, they're going to have a very difficult time returning to the owner a blown engine and expecting to be paid for their work. The fact that the engine was blown, if it's not otherwise obvious, ought to be discernable from the dyno charts.

I would think that if lifters did not get oil then camshaft lobes are oil starved also. After 10 minutes there is probably damage to camshaft lobes.

If the dyno run is not successful, don't pay them until it is successful. (Hopefully, the engine won't put a rod through the block! Eek!)

Also, if the builder knows upfront the engine will be tested, I think he will be a little more careful as he builds it.

Joe and Bill,
I hear what you are saying, completely agree and understand as one would hope, but seeing Mike only had the engine a few days and ran 10 minutes that any 'Reputable' engine shop would have stepped up and tore down the engine to see that it is/was oil starved because of what we all know without even seeing the motor......

My my point and key operative word here is 'Reputable' which it sounds like his engine builder is NOT. I am not so sure requesting a Dyno would make the builder act any different. Character and Integrity are built in and it's not something that comes and goes.

I do however agree that it'd be a lot harder for them to collect their money.

Re: 265 V8 cam bearing replacement

Engine is out of car and broken down. The cam did have a groove cut in it, BUT, it was only 5/16 wide, it would not have covered both holes in the bearing. The bearing has two holes in it, I probed both with a 90 degree pick, one hole is open one is not. So both issues would prevent oil getting to the top. The shop had the right idea, just did not do it right.I'll have a wider flat (1/2") cut in the cam and replace the bearing and make sure both holes are open. I only want the cost of gaskets, sealant, machining the groove and bearing a rear cap paid for. I'll do all the work and not charge for the time, I think that is more than reasonable....
