Ahhh Thankyou for showing this. I couldnt find the Cold start injector time switch for nothing ! Nice that you showed it out there in the open. Many Thanks

I like the setup that you have with the blue silicone hose change out and also the plug lead wires, The thing is down the bottom of the world in New Zealand it's hard to find and if you do find this it's darn expensive. I just found some of the coolant hoses through Amazon for more than half the cost including shipping but other companies don't ship to NZ only USA.

The sensor closest to the driver's side can cause hot starting problems. To combat fuel vapor lock, the ECU raises fuel pressure after a hot soak based on what that sensor tells it.

I used CRC freeze-off to get my 3VZE water temp sensor out with a 19mm Fuel line crow foot socket. I didn't break it. On that sensor is the part number from Denzo. My replacement was an exact Denso replacement with same PN. There was a copper crush washer on it. My sensor was original Denso from Toyota Japan Factory 34 yrs ago

A while back I had a leak coming from there. My 91 pickup had a recall for the head gasket years ago and the dealership did and they ended up warping then small little bypass block and just put a whole bunch of silicone so it wouldn’t leak. After years the silicone started to wear out and started leaking. I kept leaking coolant behind the truck and it would run along the transmission. Took it to a mechanic and he explained to me what the dealer had done years ago. Had no choice but to make a thicker gasket and add silicone to seal it . Sucks they don’t make that part new no more . And it is a pain in ass to get to as well.

This may be the drama im having atm, was the 4runner going into limp mode kinda where it looses power if a certain speed is reached? I've a drip leak and its either this or welch plug, can't think of any other reason why. Thanks mate

Great video. I have a leak from back there but can see if it's the hose,gasket or a crack or untill I dive further in. I here from alot of threads it's that u shaped bypass hose that starts to leak.

@JaymoTheGroGuyde

4 жыл бұрын

Hey thanks! Yeah that u shaped one on mine was ruined when I got back there. That bypass sits just above the exhaust cross member that leads out to the cat. So all that heat just rises and melts/hardens anything that isn't metal. I'd suggest going with a high temp hose when replacing. You can take it all out without removing the plenum. But I'd suggest pulling all the bolts that hold the plenum down, and then lifting and turning it over toward the passenger side without removing any vacuum lines and resting it there. From that point it's accessible and you save time rehooking the lines

Great description of this water bypass outlet. I recently replaced the temp sensor (ECT?), among other things, and now I notice my temp gauge goes much higher than previously. I was concerned about this reading. But now I am wondering if it could be the sensor I installed causing a high reading? It wasn’t OEM. THOUGHTS?

Impossible for me to tell you without seeing it. I can give you idea, the back part of this engine right where that part sits gets extremely hot due to the cross over exuast header design. All that heat rises onto this part. The seal can warp, the plastic bvsv can get brittle and snap. The hoses can become old and crack. The seals for the sensors can get cooked. Gotta get back there with a light and a mirror and check the damage. Here is hoping for you that it's actually this part and not the back side of the engine and a blown gasket

If you're hood is in good condition there is the vacuum diagram there that will show exactly where they go. I suggest going one by one, replacing each one as you take it. Then either take some pictures when done for reference or lable each line and where it goes for next time.

Large black sensor where? Most of the sensors on 3vze are metal unpainted. The mass air flow sensor or volume air flow meter is on the right side of the engine bay above the air intake piping.

The bvsv with the broken attachment tubes is not for the EGR system. That is one of the components for the Evaporative Emissions System, aka gas tank fume collection and burn off thingy system gizmo stuff.

Why remove that and bury it at the rear of the engine again? A couple of lengths of hose and a few small pieces of metal, couple of fittings and a bit of welding and I moved my son's to the inside passenger fender. Burying that at the rear of the engine wasn't Toyota's finest moment. Your engine seems to have a lot more space between the firewall and air chamber than my son's, on his that block was nearly completely hidden. Changing or checking any of the sensors was totally impossible. WAS...
