The Engine Is A Goner, Warped Head And Long Block!! - Page 2 - Toyota

Is your ECU/ignition system going to accept an engine that it wasnt initially programmed to accept?

I understand its the same model engine but what about unique ID's for each engine.

Are taco engine's made in the US?

i was thinking about popping off the old valve covers and getting them powdercoated fire engine red just for the heck if it, what do you guys think???

I just looked in the factory service manual and they do look the same. Great, now you can pick the parts that are in the best shape.

My buddy who is the toyota tech trainer did extensive research on the matter and he says it's a direct swap, he said we'll probably have to put in a new water pump but other than that it's a straight swap

I'm not sure how the engine id's matter?

And the engine was made in japan

Can I have a piston and connecting rod? I think it would make a sweet paper weight. I'm being dead serious too.

Back on topic, I think its really neat that you are taking this on yourself. And look forward to future pics and updates at your unfortunate expense!

hmmmm it would make a sweet paper weight, you'll be at the the top of my list if i start to part out the guts, im not sure what im gonna do with the internals yet, i may keep them in there for my coffee table or strip it bare and paint the block- ill keep you posted!

ah thanks, im looking forward to it too- i wouldnt have the guts to do it if i didnt have my friend that knows these cars inside and out so im looking forward to learning lot, my buddy told me "hey you have a pretty awesome truck, im sure you'll get good money on a trade for a 2010" and i said hells no im not getting rid of this truck itll be 5 years on june 11 and im not even close to being sick of it!!

hey so you have any ideas of things on the engine i should powdercoat? im thinking of doing the valve covers red, and wheni get the engine outta the engine bay im gonna detail it all clean!!

As far as over heating goes, the V6 is the first Toyota all aluminum truck engine. I remember years ago, when the Chevy Vega (worst car ever made) would over heat, it would warp the head. I don't know if the aluminum block had anything to do with it, but ....

Josh, good luck in your engine swap. I will be looking everyday to see how this goes. Be sure to post some pics.

There are a billion maybe 50 billion cars and trucks that have aluminum blocks and aluminum heads and have been driven billions and billions of miles all over the World.
It's a well known fact if your engine any engine made from aluminum or cast iron, is over heating it's a good idea to shut it off and call a wrecker.

Telling the forum if only you had a cast iron V8 you would have been good to go is IMHO just plain stupid.:awais:

Agreed. No engine, whether it is made of aluminum, steel, or kyrptonite is impervious to overheating. In fact, when it comes to warping, you're better off with an aluminum block and aluminum head than to have a steel block and aluminum head. The reasoning there is because of the dissimilar materials mated to each other, as compared to the identical properties of two similar metals. When aluminum heads were first put on iron blocks years ago, there were quite a few problems because of the dissimilar metal issues. But of course the engineers figured it all out by redesigning the head gaskets to better deal with the movement caused by the way heat acts on dissimilar metals.

Josh,

You do realize that engine is set up for a manual transmission, right? If you're planning on keeping your automatic tranny in your 4Runner, you're gonna needs to swap over a bunch of stuff...

When the belt broke I was only a mile away from the dealership and the engine was running hot so maybe that made the existing problem worse?

I have been thinking of the aluminum block engine ever since you started this thread. When I got the 2001 4Runner, Nissain had their Pathfinder with a aluminum block, but Toyota wanted to stick with cast iron block in their trucks.

I see that members are praising the aluminum block engines. Sure they are in lots of vehicles. Toyota jumped on the band wagon with this engine. I just wonder if it was the right decision. Taking a 4Runner out in the woods can be tough, with lots of abuse.

"I went 4wheeling and mud got caked in the engine and caused two pulleys to seize which in turn caused the serpentine belt to snap."

I know Toyota will come out with a new 4.6 V8, I wonder if that has an aluminum block? I think they are abandoning their tried and true principles here. Having a engine that is heavier, less horse power, but built for abuse, I guess was was then and things change. I bet the new 4Runners will have 5 lug nuts on the wheels, instead of 6. I know less weight and "lots of vehicles have them and they are fine".

Here is a link to an article about the R&D that went into the 100 series Land Cruiser when it was released in 98 w/the 2UZ-FE. The engineers say that iron was selected for the block due to its strength and "bulletproof durability". They researched aluminum blocks and they weren't up to the task. It also discusses how all the internals of the engine are beefy.

Another interesting point is the chief engineer makes an effort to say they used NO hydroforming in the production of the frame; however, today's 200 series has a hydroformed frame which Toyota raves about.

Riverrider, yes I understand there are billions of cars with aluminum blocks, those billions of cars were not meant to be driven under the harshest, most extreme conditions in the world. They were not meant to carry 1500lbs of people and gear across the Australian Outback in 100 degree weather for 300k+ mile duty cycles. I am sorry, but an iron block surpasses an aluminum block in strength and durability PERIOD.

False, there is a GX owner on another forum whose engine hit the red line on the temp gauge more than once due to a dirty radiator.

There are no ill effects on the engine at all and has resumed normal operation after a through cleaning.

i agree with you, and i cant be for certain overheating was the cause- because the misfire symtoms happenned way before (weeks to a couple months) i ever even seen the temp gauge climb so who knows what the hell happenned inside that engine until we pull it apart which will be happenning this weekend

yeah im aware, i had two engines to choose from at TAP and one was this manual trans, 2006 engine from a xrunner and the other was a 2005 from a tacoma, auto but there was no known mileage, so we decided to go with the one with the known mileage because with the other who knows how many miles was on it, but yeah there will be many things to switch over including the ECM
