EDIT***

Sepa, I had this great argument back to you, but I realize you are just going to talk trash regardless. So I will just say this. If you have a real argument (with information/experience to back it) then I will be more than happy to discuss. But simply saying I have no experience does not make it so, and is just an easy way out for you in the argument. You dont know me, and arent attacking me with your own knowledge (just blind insults). So stating those things means nothing but internet smack talk. So I will just end discussion with you there. No smack talk, no insults, nothing. My initial response, although true, is just going to prolong the argument, which is worthless.



There ya go Claudia :D

 

Why are you guys even bothering to argue?

 

I really dont know Claudia I should know better than to argue with people like this by now, since it will go nowhere. I guess I just get annoyed when someone wants to insult my experience/intelligence with no argument and only assumption. But again, I should know better :D The people that know me know what I know and what I dont for the most part, and even if what I knew DID come from a textbook, if it is correct it is correct regardless.

But, just come post and keep me in line every now and then Claudia!

 

will do I'm gonna do my car test tonight and PM u the results!!!

 

Oh yeah.... you havent done that yet I will do my best to help you figure it out. And I edited above. No reason to waste time with that any longer...

 

well done

 

So.... you guys want to see the other 3 pistons / rods / and the rest of the crankshaft? To prove or disprove whether there really was insufficient oil in the engine right?



But an oil "pump" may be pumping but if there is blockage further downstream, the oil still isn't going to the right places even though there is sufficient pressure right?
BUT, then does that mean there is no way to tell for sure if oil is going to all the right places right? Is there something such as a "FLOW" sensor - i.e. a sensor detecting not pressure but actual liquid movement? Would you need to put such a sensor at every downstream branch from the oil pump to prove oil is flowing to all parts of the engine?

 

That has been in issue for people before (not just with a tC , but in general) Some cars actually measure the pressure at bad places, so you can have blockage further downstream, which will cause a great pressure reading (no warning light) but there will be little to no flow in some areas of the block. I think toyota is a bit better about this, but you can still have a situation where blockage creates sufficient pressure readings with low flow.

Flow sensors can be finicky if you dont have a consistent makeup of the fluid you are testing, unless you use a contact type (paddle type, for example) system, which has its own downfalls due to the mechanical nature of them. Non-intrusive flow sensors can be much more complex to keep calibrated. While they can be very accurate in some instances like aviation and control systems, those systems are maintained much better than the average car is. But yes, a flow measurement would be better if it were feasible in a 16k car. But even having a gauge to determine if pressure is dropping, rather than a light that says "hey, its too late!" is a better alternative.

But as mentioned, most people feel it is not worth the investigation money to get this deep into why it failed, rather than just replacing the engine or rebuilding, which is what you have to do either way.

 

lol.... i don't want to fight. i just hate how people make excuses for this motor EVERY time something f'd up happens to it. do u really think its just a big coincidence that there have been so many issues with the 2azfe in tc's in the only 3 years of production???????????????????

its not a performance motor. its an economy motor (hence the "F" series head"). its not meant to be boosted. its meant to last a long time and be reliable. when u boost it, you are infinitely decreasing the half life of the engine, basically dependent on the driver, the level of modification, and the overall stress being placed on the engine.

lots of boosted tcs have aftermarket pistons, which imo is the only reason you haven't seen MORE blown engines.

before the tc, i don't think there were half as many blown 2azfe's, if a quarter, as Toyota/Scion is seeing today.

dude, don't get me wrong. i like the motor. i just have a few bpu's and had planned on building the motor (if i keep the car, and start saving some $$$ lol) because i like its performance for a fuel economy minded 4-banger.

its just not designed or able to withstand boost for an extended period of time. and the higher you're boosting, the more likely that you will blow the motor sooner rather than later.

thats all. i'm not fighting. its just that i've been saying this same thing since day 1, and all u naysayers have been saying your same denial, denial, denial lines... and over the last 3 years...HOW MANY BLOWN MOTORS have we heard of??

just stop making excuses. its not a 2jz or 3sgte or even 2zz block. CAMRY MOTOR people.... camry motor.

 

Kind of random but isn't there a "filtering" screen on or in some part of the Vortec unit that requires periodic cleaning? I thought I read something about it on here, maybe it was there. I don't know but maybe it got clogged and starved the vital parts of the motor?

 

Well... I can count 4 -5 that I have heard of total (one of those was not boosted and seemed to be a fluke), not counting shops that tried to push 500 whp or people that hydrolocked them in water. I would say that is about as low a percentage as can be asked for. And out of those we dont know how many were built improperly or driven horribly. I have heard of more honda engines (which also are econ engines not meant for boost by the way... but seem to pretty well given the thousands of mistreated ones out there still running) blowing up myself.

And no one argued that the car is meant for boost, I have no idea where that idea came from. If the car is moderately boosted and driven properly, there is no reason to believe it will fail prematurely. If it is boosted to a higher degree, then some bottom end building needs to be done (As with ANY little 4 banger in the econ market). I very clearly stated that a long time ago. There never was an argument about that on my end. The motor is as strong as it needs to be for what it is (And is BOOSTED by trd themselves with no bottom end build, so obviously the designers thought it was safe for moderate levels). I dont try to say it is made for boost any more than I will blindly say it will fall apart given the SMALL percentage of them that have so far.

And again, I have heard of TONS of honda engines that are in reality fairly tough motors blown... it is called kids letting crap shops slap parts on thier cars and not knowing what they are doing.

And I have yet to see an engine (Even one "made for boost") that didnt decrease in life when boosted and/or driven hard. That is 100% common sense. You are placing more strain on the motor, it will not live as long as it would under less strain.

I havent seen anyone really make any excuses in this discussion... I have seen people who seem to want to bash and argue pretty badly, and take things however they can to make an argument however.

 

yes, there is, but that was not the reason that my motor went bad, ill be able to give you guys more precise info on what went wrong hopefully tomorrow or thursday, cause they will be crakin her open then lol.

 

Keep us updated man.

 

no prob. soon as i foind out, cause im being told there is also a good chance i may need a new head cause my valves could be bad too, so well see.

 

I can't help but jump on the wagon here; why would Toyota offer a factory-warrantied supercharger if the car "wasn't meant for boost". Seeing their position on the world stage, i give them a little more credit than that.

 

My thoughts exactly.... but I think it was for the money more than anything.

 

9 Times out of 10 whiteish smoke is water getting into the combustion chamber. This is a definate reason to stop lock and drop it. Most of the time there is a blown head gasket or warped head. Not uncommon amung aluminum heads. Not saying TC's 2.5L is prone to it, but many of aluminum heads have been given the death sentence over the years.

Man oh man, if this happened to me, there would be a call to ZPI for a stage 2 engine! Don't say a word to the wife...

 

You should also take a look at the people installing them for you. Even if they are installed at the dealership, some mechanics at dealers are just plain useless (and of course there are lots of well trained ones as well). If you haven't noticed, Besides the correlation between blown motors to the camry motor, it also correlates to this fact that these superchargers are being installed AFTER they left the factory, at the dealerships.

For the record, I was offered lifetime oil change and tires with my highlander. Took it in for the first oil change, and they dumped in 6 quarts of oil in tere because it's a 6 cylinder. When I complained to them, they told me it's perfectly fine because the 4x4 models requires more oil. So no, I will not feel good about them putting in the supercharger.

Most engineered systems (not limited to automotive) that failed were caused by multiple combination of errors. I won't be suprised if this is the case for the superchargers as well.

 

SC blew my motor but i had a 9.5 psi pully so im SOL...

I had the head gasket replaced and the white smoke stopped but it still drinks a quart of oil every 400miles or so. and it ticks.... a lot.

 

We got a 2.4L buddy ;) just nit picking
