The Engine Is A Goner, Warped Head And Long Block!!
this is a continuation of my last thread:
Oily Spark Plug On A 4th Gen and Misfires On Cyl 6... HELP!!!! this past saturday night i brought my truck over my friends house (a toyota tech trainer) and we did a compression test on all cylinders and cyl 6 was pulling 199psi which was high compared to the others and that was the known cylinder that has been misfiring on startup, so we decided to do a compression leak down test, we put the engine at TDC and pressurize the cylinder and then we take off the radiator cap and guess what we see??? constant and consistant bubbling which means that the head/block is warped and since its a aluminium block its pretty much shot, sooooo i need a new engine at 128,000 miles!!! so with the info at hand combined with all the past tests, we now know we need to pull the engine which a engine pull and replace is gonna run about 20 hours!!! my friend then starts the search for a 1GRFE engine and he finds one the same day at a specialized toyota recycler up in sac only a hour away. i am going up tomorrow morning first thing to buy the engine, its from a 2005 sport with only 50k miles on it and with my buddys toyota discount its only going to cost me $1400 for a practically new engine, then the next step is the fun part....... 20 hours of pulling out the old v6 and putting in a new one, and dont worry i plan on documenting the whoe thing!!! is anyone curious about what im going to do with the old engine? well im gonna strip down that aluminum block and make a sweet coffee table hahha

Sorry to hear about your problems with the engine, that is not good news for the rest of the 4.0 V6 owners. I decided to put this in the 4th gen. section, instead of the "genaral section".
If you are going to document the swap, I will go ahead and make this thread a sticky. Hopefully, the rest of us won't need this thread, but sh*t, happens.

Your right about going with a V8, different components, harness, computer, maybe even a different catalytic converter, anyway, it would be hard, not impossible, but hard.
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.

Here is the stats on the engine: From a 2006 Tacoma Xrunner 61,000 documented miles Original plugs still in it and regular maint performed So it's still a very young engine, I can't even remember hitting 60k it seems so long ago

i asked my friend about why the engine was a goner and how come it cant be fixed and also why does it seem that newer toyotas just dont last as long as older generations and he told me its all down to the materials used, he said this engine can continue to run for years in its condition as it is all i have to do it just keep adding more water to radiator to keep it going, and there are many people out there probably with this same issue, but internally the engine just keeps getting worse and that not what i wanted, i ant to fix the problems and have a good engine again. he also said that the reason the engine is all aluminum is because of comsumer demand, they wanted a 4runner that can get 15-20mpg and how can you possibly get that? well you have to shed 400 pounds by going to a aluminum block and heads among other things- the older generations had cast iron blocks and can take more abuse but thats just not the same with aluminum ![]() the only symptom i can possibly recall to what cause this whole issue was one time i was towing a decent sized load probably 2500-3000 pound load in traffic and and then water temp was fine but then the a/t temp warning light came on and i pulled over immediately for 30 mins to cool down then i went home and it ran fine, but it was around that time frame that i started noticing the misfire but i cant be fore sure if the misfire happenned before or after-

Looks like you have a nice clutch, pressure plate and flywheel there too. Also the air intake assembly looks different than the 4Runner.
