My 318....Is no more..... :(

-
was the oil slinger installed backwards?

and does the dampener still have the metal bell pressed around the snout?

you can pull the fuel pump to see if the eccentric is loose, 4wiw

I've see where the eccentric comes loose and rides against the cover and in a matter of time cuts through and =water in the oil
 
Rule of thumb is.....its safe to have 10 psi of oil pressure for every 1,000 RPM's your engine is making.....70 PSI at an idle seems like to much....sounds like either a cam or crank bearing spun its position and the oil holes no longer line up with the block which in turn is boosting oil pressure do to the blocked off galley.....and the screeching noise you are hearing is probably a dry/semi dry crank/cam journal due to no oil getting to that one spot.

atleast that is what it sound/looks like to me.

could be something stupid though.....I have seen oild worn out carbs make that noise when sucking air through......I have seen a bad vacuum line suck air through a crack and make that noise.

as mentioned before,it could be the cam rubbing against a worn out thrust plate.

its worth going over things a bit more and then if you have to....pull the engine and go through it.

you can do a basic rebuild on that engine for $500.00 easy enough,gaskets,fluids and a cam kit or crank kit......or spend a couple hundred on a used local runner just to get your ride back on the road.

either way.....it may be a curve ball and be more money but think of it this way....say you were sick of it and were ready to sell it for $2500.00.....now say you may have to invest $500.00 into it to get it back on the road.......now add those two numbers together.....would you really sell your running and driving ride for $3,000.00? I wouldnt.

so hang in there and figure it out buddy and good luck!

good points....I did not even think of the eccentric coming loose
 
Could be the front pump bearing in the trans....check for the noise in all gears.
 
well. I pulled the oil filter and drained it...there are no metallic particles, I ran a magnet in it as well...no metal particles...I checked the trans, I don't think it could be that...I'm almost certain the oil slinger is correct..I guess I could pull the fuel pump and check the eccentric..And yes, the damper still has the metal bell stamped on it...

normally I would pull the drain plug and check because the metal will normally settle to the bottom of the oil pan if there is any.

and I could see where he may think it could be the trans making the noise...I have seen them make some funky noise's before.

one trans in particular I had was a 42RH in a jeep grand cherokee with a 318 in it.

I was driving it down the road and it sounded like nails on a chalk board....a very prominent screeching noise......BUT it was only soon there after that my tranny started shifting funny and the hole truck started jerking and then I lost over drive and I beat the crap out of it lal the way home and went to the yard the next day and got a new tranny and problem solved lol.

so I wouldn't rule tranny out just yet.

you really need to determine exactly where the noise is coming from and then move forward on diagnosing what could be worn out/failing that would be causing the problem and then you can move forward on fixing it.
 
You sure it's not the freakin flex plate bolts hitting the freakin dust cover on the tranny that made the same noise on my 440 build?
 
Well it sure sounds like its coming from the engine...It gets louder as you rev it...

torque converter spins with the engine so it is not to say that its not the tranny making thew noise as if the issues was in the tranny it would also make the noise get louder as you revved it up
 
rarely have I seen them make a noise BUT I have seen the oil pump gears wear into the oil pump cover over time which could cause a screeching noise.....I have seen this mostly on melling parts though.

doubt that is your problem but figured I would mention it
 
It's got to be something else. Not a spun bearing. Just take it slow and check out all possible causes. I know how you feel. I've been there with other cars. You'll find it. Best, Mike

I understand, point taken....I'm just stuck now. lol...don't know what the hell it is, but it sure sounds like its deep in the engine, and it has to warm up slightly to make the noise...
 
did you put a new distributor bushing in?I have had them to seize to the shaft.Any way if it comes to it go for Moss Landing.I have had good luck out there. hope it is not serious

IMO don't run it anymore...you will cause further damage if it is internal...drain the oil through a white rag or paint filter....look for bronze or copper looking material..if so bearing problem...pull her out..take the timing cover off first and have a look see....then flip her over and take the pan off and have a look see...start there and you should find something...then take the main caps off and see if you spun a bearing...

No, no new distributor bushing...

Water pump bearing.

Not that either...I had it running with the belt of, still made the noise...

I'm gonna have to agree with you on this one...I did drain some of the oil though and I found no metallic particles...I did run it one last time right now, and I noticed that when you slightly rev it very slowly, the noise progresses...Like the cam may be thrusting forward...You can't really hear it when you rev it fast, just kind of a slow progressive rev and the noise becomes evident...

Also, I'm gonna pull the fuel pump like was mentioned before to see if the eccentric is loose...I'm not really sure on what to look for though, or how to tell...
 
I have always used blue loctite on the cam thrust plate bolts and the fuel pump excentric bolt...
 
Back in the day when we used to do timing chains on these engines we would replace rhe front crank seal, and it would squeal. To fix it we'd take a knife and with the tip scratch across the balancer hub where the seal rides six times evenly spaced around the circumference.

stick a flat head screwdriver in there and pry a lil between the eccentric and timing gear or even wiggle it between the cam gear.

see how much the cam/timing gear moves forward.

does this one have a windage tray?
did you use the washers under the 340 main bolts if so?
if it has the tray and you didn't use the washers...the mains are loose or not torqued enough cause the possible bearing issue.
340 main caps r taller than 318 caps-bolts bottom out slightly giving inaccurate torque reading.
just shooting in the dark...
 
OK well I got the timing cover off...One thing that was kinda of weird was when I was pulling the harmonic balancer off..It came off by hand, it was a little difficult to do by hand, but as I grabbed it with both hands and wiggled and shimmied it off, I didn't have to use a puller...Is that bad?? Do I need a new one, and check the radius of the crank snout?

The timing chain is a double roller and was tight, didn't appear to be worn out, and the cam thrust plate behind the timing gear was tight, and it doesn't move forward. The eccentric was okay and so was the oil slinger..

And the harmonic balancer wasn't rubbing on the timing cover either...

So I guess the next step is to pull the cam...So I'm off to pull the manifold and rocker gear to get that cam out...

I havent read the hole thing yet but I had to stop and comment as soon as i read this lol......THAT IS NOT RIGHT!!!!!!! you should NOT be able to pull it off by hand! you SHOULD have had to use a puller....them suckers should be on there GOOD.

now you need to find out why thats the deal.

was it even onn all the way to begin with? were the bolts tight? was the center bolt tight? you may have the wrong balancer for that crank?

does the front seal look like it has wear? does the balance have any wear groove in it from the seal? does anything else look out of place.

I do know that it should come off by hand though,so something aint right
