???????WHATTTT?????????? ???????WHATTTT?????????? You really need to read what you wrote. 90% of it makes NO sense at all.
If you follow the Brazilian system to the end, you will not only need to pull out the tube from the EGR valve and intake manifold, but also close the hole on the intake manifold with a special part. 17123-37010 Cover, Surge Tank
prove to them your an idiot, come you up with bulletproof plan something not add up reveal to you your flaw you come here stating that you gonna fix you a head gasket then some trolling narrative on that internet made you have hope that you didnt, and that your prius was just drinking its oil from PCV/EGR then your panty was up in a bunch when you found out again that you need to fix you a head gasket what an idiot now that dust settle, come you up with bulletproof plan and share the whole process with forum exact plan: get you all the part that make prius engine bulletproof, build it with clear picture and help other keep their gold in their pocket, and keep gliding through their realm japanese engine purring you read couple post on this forum where people put jdm part in their prius engine goal: put you some high grade quality product inside your japanese block experiment: can we make prius engine not have the gasket issue and be bulletproof? get you the highest quality gasket even if it is not toyota get you jdm piston/ring/connecting rod bearing get you maybe new jdm connecting rod (optional) anything high grade made in japan catered to solve this issue (within reason) suspicion: with some investment, we can build BULLETPROOF jdm prius engine and solve the headgasket issue once and for all yes, also @MAX2 spill sauce on the brazilian prius without the egr scam woah, could this thread take you the whole way, make your 1.8 japan work of art bulletproof? where 1. bulletproof inside engine with jdm, 2. do an actual egr delete where no exhaust get inside your japanese investment get you around the "check engine" using nerd method summary: everyone spill the sauce on what need to get ordered asap, and spill the sauce on how to do nerd stuff about the full egr delete
Are we rapping or creating automotive poetry? There is nothing that will make a gen3 engine bulletproof or even as good a gen4. No one is putting JDM parts in their gen3 engine. Some put in the Toyota revised parts for a gen3 engine like pistons, rings, intake manifold, egr valve, head gasket and updated ecu software. But doing that on a bad engine can easily fail when the block or head have cylinder scoring, warping or the head was not rebuilt. I assume you mean get around the egr delete check engine light and code. Please describe how you do that; it's a new one to me. The egr test runs almost every drive and tests for egr valve control. It also tests for flow at cruising speeds and for no egr flow at low rpms. -------- What have Thousands of people before you with Worn Out engines done for high reliability? a) Replace with a professionally rebuilt engine from a place like Hybridpit and ensure they get the version with revised pistons and rings. This option could be implemented by most shops or by some diy'ers as could option b). b) Replace their gen3 engine with a hopefully better low mile gen3 used in Japan JDM engine. This is the lowest cost option here but the biggest risk. It may not be low miles and it may not be used in Japan. It could be a JDM engine from 2010-2021 but there is no way to tell which year. It could also be another worn out US engine sold as JDM. Nevertheless it is an option that might make sense to the budget constrained buyer who does not want the cost of option a) above or the complexity of option c) below. c) Attempt to install a good gen4 engine into their gen3 car usually with gen3 ecus, exhaust, egr system and some custom wiring and aux cooling setups. This option is almost always diy. How to avoid a worn out engine is another subject that is irrelevant at this point. Plenty of theories on Priuschat.
woah they are obsessed with putting your exhaust back into your engine why can't we just rig it up like the Brazilian prius that does not have the egr? can't we remove the egr plumbing, then play with the computer and program it the same as the Brazilian version so that it runs fine without the egr nonsense? also more reflection: you don't think you saw a radiator cooling down your Japan investment is that true? that there is no radiator? woah in the new age, your manufacturer cannot afford to give you a radiator, since they are bogged down by fees/lawyers/egr crap so now, when you buy a car, you literally have reengineer their system so you can protect you asset/gold, unbelievable plan: experiment with your part prius to get to the bottom of: running your engine without it taking in exhaust into intake when you do the heart surgery on your main prius: your fixing to install a big ol radiator with the plumbing and everything, just too cool down your Japan hybrid robot covered in plastic, inhaling its own fart, woah summary: experiment with prius software to try to make it run like Brazilian prius without inhaling fart, and add you a big ol radiator to protect you gold/Japan engine you think if you figure out the Brazilian software to get around inhaling fart, then a radiator will make your Japan hybrid bulletproof now: Japan hybrid running fine, just burning 2 quart oil per month, but it has not left you yet stranded keep you thinking and planning the big surgery theory: if you get your engine to run without inhaling its own fart, and you add a big ol radiator, your Japan hybrid will be bulletproof
True, its more related to bypassing the EGR, but from what I read it did seem OP was trying to fix the HG too
Ok I will play along Because you need all the Brazilian ecu software for multiple ecus and likely their wiring harness. Toyota USA is not going to sell you that because it's a technical problem for them to execute at a dealer level (no real gurus there) AND it would be a federal and Cali state offense. No one has "jailbreaked" Prius software and network integration, no matter what one individual here claims he plans to do. So you either block the egr flow (no need to delete) and live with a check engine light OR you realize the egr flow is only a problem when your car burns two quarts a month. Solve the oil burning with options a, b or c above and you get a smooth running, no oil burning engine for 100k-150k more miles. And that is not irrational "spitting hot fire". Of course it has a radiator, several in fact. One for the engine coolant, another for the inverter coolant, with other coolant heat exchangers for fast warmup and of course, the cabin heater. The gen3 cooling system works great and can take 110f with full ac all day long without breaking 200f. The light comes on at 248f and should say "Stop Now or Else". The reality is gen3 head gasket and oil burning problems do not need overheating to occur. In most cases failed engines have never overheated. The cooling system has two electric water pumps which on occasion with high miles "might" fail. Some will preemptively replace the engine water pump at ~150k or so. However others including myself just change the coolant every 50k and have the original water pumps 320k later. . This, in my humble, non-spitting opinion is the heart of your problem. Fix this with options a, b or c and you also get engine reliability along with reduced carbon clogging up everything.
In that case my question is answered. I didn't know that removing EGR systems was illegal. Makes sense though. One note, I keep seeing the fact that Brazilian Gen 3s lack it. I would assume that is because that country has lighter exhaust regulations? Also is it possible that temperatures there don't need the engine to be warmed by it?
Yes Brazil probably doesn't need it to meet emissions laws. Which is the purpose of egr (exhaust gas recirculation), not to warm the engine. Some efficiency gains are possible but typically in turbo charged engines. Gen2 Prius have no egr and they meet emissions primarily due to a very expensive catalytic converter people like to steal. Gen4's egr was redesigned to take cleaned exhaust after the cats and never needs to be replaced or cleaned. Another system most people don't know about helps the engine's throttle body warm up quicker. It's called the Exhaust Heat Recirculation System and is under the car behind the catalytic converters. It is pretty elaborate but since it's reliable on gen3s no one complains about it. Even if it fails it can be bypassed without generating codes. Gen4s sometimes have that problem.
nerd call, you're not being trolled ok yes put you out a nerd call: nerd, we call upon you to open our eye and tell us how to run prius without egr, just like the prius in brazil, maniupulating harness/programming with a tool, something we know you got the sauce but cannot share for whatever reason why do people wear a shirt that say, "I am the warranty"? ok yes, here is some sauce, play you with the wire harness and trick the system using all nerd method there will be no consequence since the car total anyway, experiment start soon exact what y'all witness in the thread: all new connecting rod bearing, piston, ring, head gasket, spark plug, injector, etc for inside engine, then, add you a big old METAL radiator after you throw away half the engine bay in the garbage if successfully trick computer and have no fart go inside your investment, then we share the sauce with world if not, keep egr system intact, and fully plug the exhaust port into intake, but that also starve the engine from air since prius without throttle, does not take in much fresh air is the statement true: now, your prius does NOT have the harness plug into egr, BUT since the plumbing is still there, while it is idling, it is STILL pulling in fart into intake critique the statement your not being trolled, give the thread a second, we fixin to do major surgery/custom thing/nerd stuff reasonable plan: get your part prius alive again, move it to the work area, rip off all the plastic junk, experiment with nerd tactic start to get the new part for your engine to build ordered maybe: fix you back up the part prius enough to drive, use it while you do major heart surgery on main prius
