Gotta put the video on pause while I go change my oil ....

How appropriate that this was for the oils campaign

[jameswhiting]

4:03 not a cam sensor, it’s a vvti solenoid, if it’s full of sludge then there is no oil to the vvti controller then the cam leaves the chat 😂😂

[psylence]

Yeah how long ago was this Rav4 project because the Brumby is in the background?

My Mini has been in storage for 7 months... BRB, going to do an oil change real quick.

I wanna see you guys spice these engines up a little more man. Cams, stroker cranks, rods, big bore, cams etc... I wanna live vicariously thru you guys. Yeah nuggets are fun.. but let's see some absolute beast nuggets every now and then.

I have torn apart a couple of Lada 2101-2107 engines, most of them look even worse than this one, because back in the day they had no good oil, so ran M10 oil. But the engine is so simple and designed with large gaps for bad oil to flow, so it works like this for pretty much the whole life of the car. Oh and nowadays we don't have thick oils, so pour 15-w40 and the engine is not happy. It likes 15w-50 and still has low oil pressure. They fixed the issue on their newer engines like the 2108, 2109 and the Niva.

For what its worth - The hole in the upper shell of the bearing typically leads to a very small hole in the upper half of the rod, which squirts a small jet of oil towards the piston/cylinder wall.

Check out another channel on youtube called "I Do Cars"... it's a guy in Missouri USA who owns a salvage yard (wreckers to you guys) and his whole thing is tearing down blown up engines to see why they failed. Some of the failures are catastrophic others are like the RAV's engine... it's a pretty interesting look into why and how engines blow up. He also does videos on how the salvage business works. In most cases, the engine failures are caused by neglect... lack of oil changes.

After the "Dyno Disaster" i was patiently waiting for this lol. Not the bearing I thought shat the bed but jeez that's sludgy

[HeidiFegles]

Regular maintenance is key. Also caring about the vehicle you drive, it’s amazing how many people buy a car and do nothing to it but out fuel in it, drive 100k to major failure. No oil changes, pretty much nothing, then mad that it didn’t go 1 million miles

[crezychameau]

I wish I had this many friends into tinkering, a night wrenching with tons of friends who know their way around tools sounds like an insane good time !

[IahushaIahuah]

When I saw the oil pan taken off when you first started i saw the engine sludge

[button-puncher]

Run diesel oil in an unknown engine. It has MUCH stronger cleaning agents in it and can help clean out old sludge. Change after a week.
BTW, diesel oil can also free up and old/marginal manual transmission. Same process. Only run for a few days, then put gear oil back in.

The Brumby is back for warranty issues...!! Ha ha.. Love your work guys... Now i know why you guys are in shorts...!

[skylarstark]

Would love to see Issac on the channel more (or his own if he has one). He seems to know his ass from his elbow in this kind of stuff!

FYI ... I deleted the balancing shaft on my 2012 Mazdaspeed3/MPS3 and it's not as bad/rough as people says. I get quicker engine respond. It's been 4 years and 60, 000km since the delete. OEM driver+passenger engine mount, only the gearbox mount is solid.

[itsneuman]

exact thing that happened to my engine. Toyota 1zz. Openly admit to poor maintenance. Mine happened at 185k miles. Car leaked and burned more then I could ever change. So it was just a matter of time before low oil level and heat caught up with it.

[huddy]

I rebuilt a 2az-fe for a Scion Tc was not cheap even going with some chinese parts the ticket is put the gen1 intake cam in it and the gen3 rav4 exhaust cam it has some chop and really wakes one up

[liamcollister]

By changing the oil to a good Castrol might have accelerated this, the cleaning agents in the Castrol may have dislodged the sludge.
