Perhaps the P11EE is the key rather than a lifter problem per tsb (in this case)

Interesting. I haven’t heard this theory yet. Thank you!

FYI - it COULD coincide with your scenario because when a crankshaft position sensor (sometimes referred to as "CKP" or "CPS") goes intermittent, it be CAN BE when the sensor becomes warm/hot. The caveat being many times problems with the sensor trigger its own code.

If a hot sensor is the problem, it would:

1. Cause the engine to stop if it is running
2. Cause the engine to not be able to start until it (the sensor-not necessarily the engine) to cool sufficiently.
3. If the engine happens to be shut off before the heat event, the temp could rise when off (kind of like how a steak continues to cook when resting off heat) and reach the point where the sensor problem triggers, to the car could appear to fine, but unable to restart.

See caveat about CKP codes.

TO ME, the pipes seem kind of pricey for what it is - it's not like they're replacing the actual valve or cooler (at least according to what's in the statement).

Interesting as they are stating the direct/port injectors for #2, seeing as it does not SEEM to be the issue of the past. Assuming it is correct, I can kind of see that price. Even good aftermarket injectors can run $300+ EACH, and they are saying BOTH direct and port, which requires removing the intake manifold (and all the junk along the way). Obviously, a lot of the steps would be done concurrently when doing both.

I'm glad I DIY though.

For the coolant hoses, it's POSSIBLE just because it's in the same general area, but if it was the cause, it would LIKELY just be a particular hose - not multiple hoses as indicated (at least to me).

 

[wty]

Just to what it's saying, current Ravs use 2 fuel injectors per cylinder - 1 direct (that injects fuel directly into the cylinder, and one port (that injects the fuel BEFORE the cylinder)

This is what makes Toyota's method superior to other full direct injection systems. Cars with ONLY direct injection (VW being infamous) eventually crud up the intake valves and require crazy cleaning (which can include blasting with a nut shells (for example) to clean the crud up. Toyota uses the dual method so the fuel injected via port washes over the valve as it goes past the valve into the cylinder while more fuel is injected via direct. The main drawback is with 2 injectors per cylinder is that it can make things more expensive to both diagnose and/or fix.

It appears they are saying both the port and direct injectors, but in your first post you said you already had "injectors done." Was that all injectors, or just particular injectors, was it injector replacement or just dumping injector cleaner into the tank, etc.?

It's POSSIBLE a plug can be bad from the get-go, though not very often - who did the plugs/what kind of plugs/where did they get the plugs?

Edit - I just went through the thread and saw that a dealer did the plugs and coil, so most likely Denso or NGK plugs and Toyota (Denso) coils, so more likely fine than bad - but still POSSIBLE.

 

[wty]

Has anyone done a compression test?

 

[wty]

What did you mean by "injectors were done?" Replaced, replaced all, dumped fuel injector cleaner into the tank and ran it through? There are a lot of variables in that statement.

 

[wty]

I don't know what they're seeing, and it's only screen grabs, but I don't PERSONALLY see any reason to replace those hoses - in the full video, does it show some kind of dripping or corrosion around the ends of the hoses? I don't see any issue in the grabs myself.

You said "both injectors" - both injectors for ALL cylinders, or both injectors for only one cylinder? That would be a pretty impressive bill at dealer prices if all injectors were replaced. Perhaps post a snap of the receipts to date so people can see EXACTLY what was done to date.

Edit - OK, I think I see pink, but it's not clear enough to see what the pink is - coolant, marker ink, etc. Like if it's all coolant, some of those are in pretty odd places if it's leaking hoses around the EGR system. An example is the pink around the oil dipstick (last pic).

 

[wty]

Perhaps take better pics yourself and post. Your description of it being "foam" is odd, and the pink is oddly bright for residual coolant, even though Toyota's current LLC is pink. "Staining" from residual coolant (like from a leaking hose) doesn't usually look like "foam."

 

[wty]

Hard to tell on the others, but the first pic is definitely coolant leak at the hose/pipe junction. The "foam" is residual chemicals and chemical reactions that can occur between the coolant, surrounding air, and at times the metal of the tube (in this case). That first pic is pretty blatant, and if so, I am surprised the first dealer didn't address it even if it wasn't covered under warranty. That much doesn't happen right away, and would have been leaking for quite some time to develop that type/much residue. A fresh leak would just be some filming and staining.

What is the mileage, and when was the last time the coolant was replaced (if ever)?

 

[wty]

At 84k, the coolant likely doesn't need replacement yet (unless it's contaminated) - Toyota Pink is rated for 10 years/100k - but from the looks of it, it has been leaking for some time.

 

[wty]

TO ME some of those spots don't APPEAR to be anywhere near the EGR valve or cooler, but it's hard to tell.

The red circle is the EGR valve, the green is where the EGR cooler would be attached to the valve. Both would have hoses going in and out to deliver coolant through them.

egr valve for your rav - coolant tubes circled

This should be the same for yours - egr cooler with coolant pipes circled
