Need help identifying a knock

[John_piv]

Hey y'all.
Finished a ZF-5 installation a little bit ago and went to go test drive the truck. Engine's knocking, hard. I was hoping it was fuel knock, so I cracked all the injectors; to no avail.

I run WMO, so I'm hoping its something gummed up; but I want to see what y'all think. Could be blown turbo as well. Tons of oil in the cold side, but that could be from the PCV.

What're y'all thinking?
(Fingers crossed it ain't to much to fix)

Pull the dust cover off, it's your problem.

You very well could be right.

Of course his cats won't be safe anymore, but his truck will be quiet.

Seriously?

Don't have any cats, and do you mean the cover on the bellhousing?

There was a discussion a few weeks back about how the dust cover saves feline cats, not catalytic converters. Jesus Freak is just trying to make a funny. I doubt it's the issue.
I don't know enough about wmo burning to really be helpful, except to hopefully eliminate that it's not the transmission.

Yes, seriously, the dust cover under the flywheel.

 

[John_piv]

Yes, seriously, the dust cover under the flywheel.

Tried that, no change. Did seem to be contacting by a hair, but not the source.

 

[Jesus Freak]

I don't know then. The single mass flywheel will bump it just right and make a terrible noise.

 

[Jesus Freak]

WMO shouldn't cause it to make any noise.

 

[John_piv]

WMO shouldn't cause it to make any noise.

That's what I thought, I've been running it for about 9 months without any issues. My thought was maybe something could be gummed up and causing fuel knock.

How long had it been since it was started before finishing the transmission install?

One thing that's nessicery if you run a heavy mix of WMO like us Florida guys can do is a monthly blow out. I have to get hay once a month and it's a 60-70mile round trip with some steep hills and good pulling opportunities to get the EGTs up and clean out the precups, valves, and such. So if you've just been casual driving for the last 8mths, you need to GET ON IT!!!

It started just before. That's originally why I did the trans swap, it I thought the clutch / trans gears had gone
