Taking a Sharpie marker and coloring in the wear area on the oil pump driveshaft would quickly eliminate or validate current rubbing/interference as a possible culprit.

Any chance camshaft end play versus the depth of rear cam “freeze plug” be too tight allowing contact?

TedRamAirII · 08-22-2019, 08:39 PM

Has anyone spun the engine over, without any spark plugs, with the distributor in, and hear the noise when cranking? If you did then took the dist out and didnt hear it? then "there's your sign". If the distributor gear has any undue wear in one spot, then the cam gear would be a suspect. I'm kind of surprised the oil pump has such a thin bottom plate.

Is it me or is the oil sludge- like in that oil pan pic?

TedRamAirII,
I honestly don't remember if we did that or not. I have everything written down on a notepad in the garage. I'll check tomorrow. My head is just spinning over this engine. Test after test after test and the same ol knock.

grivera,
Here are a few pictures from an oil change we did on June 2, 2018. Looks almost the same a little more than a year ago.

I mean the pad on the block, so no matter what distributor is used it would still be off. Not your problem I'm sure, just brain storming.

I still think it's going to be something so simple that no one ever thought to look at it.

Va68goat · 08-23-2019, 06:41 AM

dataway,
I hope it's something simple but at this point it looks like something simple inside the engine. I think there are a few more things that the tech has to diagnose.

IS that metallic, ferrous or aluminum, moly? assembly lube, or something else?

Va68goat · 08-23-2019, 12:41 PM

STEELCITYFIREBIRD,
We've run a magnet through each time and didn't find anything concerning. I know the June 2, 2018 oil change Paul indicated that it was assembly lube.

The tech is coming over Monday to check the spacing of the balancer to the timing chain cover. He noticed that the balancer was so close to timing chain cover that he couldn't even fit a piece of paper in between the two. He's coming over to possibly add spacing by taking a little more off the timing chain cover. Paul had to grind down the timing chain cover because of the aftermarket balancer.

The tech asked me to take off the balancer to save him some time. So my buddy and I did that today and we notice an oil leak at the seal of the pan. Whats a good fix for that? Just add more sealer?

mgarblik · 08-24-2019, 08:08 PM

If the balancer is a source of any type of knocking or ticking, there should be witness marks on the balancer or timing cover where contact has happened. Good luck.

Va68goat · 08-24-2019, 08:16 PM

mgarblik,
Yeah...it was a long shot but it doesn't seem like thats the source of the knocking noise. There wasn't anything suspicious. What about this oil leak that I now need to address. Can I just put some more sealer and hope for the best?

gtospieg · 08-24-2019, 09:17 PM

More sealer won't do it...you really need to seal the gasket to the pan and the timing cover which can't be done adequately with the pan on. I assume this engine will be coming back out(sorry about that) and you can fix the leak then.

Honestly, I wouldn't worry or be concerned about the little oil drip right now. Stay focused on the prize. That little drip is either the front crankshaft seal or the front of the oil pan. Easily dealt with later. Especially if the pan has to come off for more evaluation, no need to seal it up 100% now. Good luck with this.

grivera · 08-24-2019, 09:51 PM

Barely any clearance between balancer and timing cover- that isn’t good. Have you checked crankshaft endplay?

Va68goat · 08-25-2019, 07:40 AM

gtospieg,
Damn..Yeah, it looks like this motor is going to have to come out at some point. If the tech is the person thats going to open up this motor, I'll let him know about the oil pan seal leak.

mgarblik,
Yeah that makes sense. Just frustrating worrying about intake vacuum leaks and oil pan leaks and we're no closer to finding the source of the knock! I'll post some pictures of the back of the balancer so you can see it. We didn't see a smoking gun. If you look at the pictures of that I posted of the oil leak, you'll see some marks on the timing chain cover but I don't know if thats from Paul making clearance.

grivera,
Here are a few pictures of the balancer installed. The tech tried to fit a piece of paper in between the balancer and the timing chain cover and it would't fit.

Wow! Was it scraping with engine running?

Paul- was it that close when assembled? Wondering if the thrust bearing has been compromised.

Va68goat · 08-25-2019, 08:13 AM

grivera,
I just took some pictures of the back of the balancer. I spun it around a few times so you can see it at different angles. I don't see anything. I think the pictures of the balancer installed may have been a little deceiving. It looks like it's hitting but theres no evidence to show that it was.

redhawk44 · 08-25-2019, 09:15 AM

My first thought when I saw the pic of the front of the crank was that it seemed short. I just closed mine up and put the balancer on and while I didn't measure it , it seems like there was more of the snub sticking out.

Seems the front crank journal and crank timing gear would affect the depth of the balancer rather than the length of the snub- I believe the balancer sleeve buts up against the face of the gear. That being said, I assume the short appearing crank snub is an optical illusion as it’s a factory 455 crankshaft. If so, the balancer dimensions may be off.
