Yes, won't hurt anything, you're cutting the fuel delivery to that cylinder and removing a lot of the load. Hoping to reveal piston slap and determine how many cylinders are involved.

After giving it some time and receiving a very generous offer I have somewhat of a plan.
I'm gonna get it looked at by a trusted mechanic before I pronounce the engine dead.
I then have had an offer from the mechanic to supervise and help me rebuild the engine at his shop, I just need to buy parts!
So the beast will run again, I'm very grateful for the opportunity to learn more about the car.
I called a few places around Australia for rebuild kits but outside of ebay I can't really find full kits. Toyota said they don't have anything and basically can't get anything from Japan at the moment so it looks like I'll be going aftermarket. Before I get too ahead of myself I'll wait and see what the diagnosis is and what I'll need.

For the guys suggesting piston slap, how quickly would an engine go from sounding normal, to hearing the slap/ knock line in this case?
My fzfe started knocking in the last couple of days. To start with it sounded like it was a change in the exhaust note (it's been offroad a lot in the just week). Today it was obviously more than that.
My oil pressure dropped and is knocking hard. Sounds similar to the video worse under load.
In sure mine is a big end bearing.

Piston slap isn't going to drop your oil pressure. Slap is annoying but can be lived with for a long time usually.
Stop running the engine!
To me sounds like connecting rod!
Drop lower pan to verify bearings.

Its been parked up since those clips.
Putting it on a trailer tomorrow (hopefully) and off to the workshop to open up the engine and see what's what.

Ok, truck is at the workshop. This weekend I'll be digging into it with a great mechanic and hopefully find the cause!

Not looking good! Will be pulling it apart further this coming weekend.
My only hope is that the crank is ok!

Can't speak for @Burritobut (and he hasn't logged in since Aug22).
Mine was big end bearing failure, and a cracked crank shaft

Ummmmm......you know those are the cutouts in the top of the piston to prevent that, right?
These are not interference engines.

Yup exactly this for me too.
Bottom end bearings were destroyed and the crank unfortunately is cracked.
I have been busy with work but still looking for a replacement engine.
Yeah I am wrong as I am a newb. lol.
For the pro’s-
I just picked up a buddy’s 97. It has recently developed the dreaded piston slap in #1 and #3. This was diagnosed by a very reputable Toyota engine machine shop. But, is this typically something that can be temp fixed from the bottom end with new bearings or….. can they really run for another 50k-200k miles? I have an LS swap planned for sometime in the next 2 years so hopefully don’t NEED to worry about it. Or I’ll maybe find a donor. Thanks
