How do you flush metal out of motor?

Okay, what should I do? The gear on my cam that drives the distributor got eaten up and I am going to be putting it back together in a month or so with a new cam, oil pump, and distributor (or just a new distributor gear). See the pic and you can get an idea of how much metal is in the motor by the amount of the gear that is missing.

This motor has 6k on it. How much do I need to do to try and get all of the metal out of it while it is apart? I was not going to remove the crank and pistons. I just planned on removing the caps one at a time and checking the bearings on the cap and the crank. I would also check rod bearings and the crank without removing everything.

Do I need to really try and flush everything out?

Thanks

Personally me... I would look for chunks and have somebody spin it over by hand. If its been wearing like that your filter should of caught most of it. I would swap oil a couple of times though. After fire up, break in, then do it again just to make sure. then do it again till u feel comfortable...Thats what I would do, but theres some people that would tell you to take it apart.

It does not get in the bearings without getting past the filter somehow. Cut the filter open, if it isn't absolutely plugged with metal, it didn't bypass.

I would pour diesel fuel or kerosene down all the pushrod holes to clear any grit out of the valley.

I'd pull it apart and flush the whole motor out. Probably I'd just run it down to the local machine shop since I don't have a degreaser tank and just let them tank it for me. Would mean a set of cam bearings, but I can live with that if it means a known clean engine thats not going to get screwed up with metal shavings. I'd also want to look over all the bearings anyway just to be safe.

I shredded a couple dizzy gears before, I kept killing cams with the "recommended" steel gear. After the second cam gear died, I put a plastic gear on and all my problems went away. I just changed the cam and gear (& oil) each time. Didn't have a problem with it. It may not be the best way, but it worked.

Wow, I really did not want to do a full teardown. That is why I had AD Performance put the shortblock together! Now I have to do it all myself anyway! I don't trust any local machine shops to do anything, which is also why I had ADP do it.

How much will I miss with some kind of solvent and a compressor to blow things out?

there is no mannor to really be assured that it is clean inside the oil galleys unless it is torn down and washed / scraped / brushed clean and then using long brushes, go in thru each galley ...


but a lot of times, you will take the chance of just cleaning out what you can see, and then putting in new bearings and be done with it.


only when it fails again afterwards,
will you regret not tearing it down...

there is no way to know....

you will do what you think that you can get away with.






do you wipe your a$$ just once or twice,...??

or do you keep on using paper and water to clean it all up iuntill you think that it is clean enough to eat...
