Rod knocking after pulling trailer up steep hill

Definitely interested in camshafts removal/ installation process. I thought that a camshaft cradle is used, but is not. Would be very helpful to see the process. In the cradle you can lock camshafts so they don't accidently smash valves against pistons.

 

again, I don't know nuthin about nuthin but even if it was 10k OCI, shouldn't be this sludgy right??

 

The more we see the worse it gets

 

It's unrelated to the engine here, but why don't more people soap and hose down the engine bay... especially before tearing down the engine? So much random dirt and grime that in many cases could be rinsed off before opening up sensitive areas.

 

Prior to an engine tear down, yeah, I get that, but as a general rule, no good ever came of washing down an engine bay simply to clean the dirt and grime away.

 

Makes it much easier to get to things and check stuff without needing to change your shirt or degrease your hands after lol.

 

At

The reason it’s not recommended is just because the water can inside wire connectors and corrode things like that. Not such a big deal in a hot and dry area that it’ll evaporate fast, but if you’re doing it in the Northeast or something in winter, probably not a good idea.

 

Okay, here's the timing chain.



and the cover.



And the oil pump



Next we'll get to the crank/bearings. After that I'll loop in the local dealer that did all the oil changes and get their feedback. I want to be able to point to the part that we can prove failed to warrant the tear down before I let them know the story.

So far I haven't seen any bearing surfaces that are smoked, just sludge everywhere.
If we pull and clean the heads and check everything, I don't see why it couldn't just be put back together and run, then we'd know what we have.

 

Are you sure they actually did the oil changes ?

 

Wow, that thing looks baked!

 

Well you sit in the truck the whole time. I could hear them draining and refilling, but you can't really get out of the truck and watch to know specifics. I'm not sure what they did every time, but they check air filters, cabin filters and a bunch of other little stuff, rotate the tires, etc. Hard to be specific about each time, it's been 177K miles.

 

Are those rubber o-rings on the oil pump? They look cooked.

 

That motor got hot .

 

I would certainly ask for a printed copy of the service record.

 

Looks like RTV to seal the timing chain cover, not a part of the pump.

 

Yep, I'm sure we'll have some money in gaskets.

The water temp has never been hot on this rig, even after the rod started making noise <shrugs>, even in the times it's been offroad.

 

They let you sit in the truck while they work on it?

 

The dealer lube shop is a drive up, you just roll in, they do stuff and then you roll out, never get out of the truck.

 

I've watched every Toyota engine teardown video I could find in the last hour. NONE of them looked like that inside. What's up with the brown film all over everything?
