R & R 4.6 ANYONE DONE IT?

Seems my 2010 4.6 engine has had some kind of chemical reaction in oil system and the RESULT was a complete engine SHOT TO *&%^ 154,000 on it! So purchased used one and cannot find detailed info on how to R & R. Hoping someone can point me in right direction. I do not deal with local dealership (past issues with my Tacoma) I did research on Toyota Tech site and even paid for the 2 day trial and nothing on actually removing engine! I have the certified mechanic and all the parts but some actual true instructions and tips would be beyond appreciated!
I replaced the engine in my 1985 4Runner with my dad years and years ago but WOW THIS IS A WHOLE NEW BALLGAME!
Have had 85, 96 and 02 4Runners, still have my 02 Tacoma Limited V6 with 210,000 on it and now after only 4 years of ownership of Tundra it has let me down! HELP!

 

Hi, I'm thinking r&r is removal and replacement. I find it odd that there was a chemical reaction of some sort? Where there oil additives? These little 4.6's are usually bullet proof and long as the oil level is maintained. I hope someone else chimes in with more mechanical knowledge.

 

So, Stacey, chill...it's all going to be OK.

From the Toyota Tech site, what you needed was the 2010 Tundra Service Repair Manual. I've never used the tech site, so I have no idea how it's organized, but the 2010 Tundra Service Repair Manual is what you need. You can try to memorize it, but I recommend printing the pages you need.

In the 2010 Tundra SRM go to section "1UR-FE">Engine Mechanical>Engine Unit. That sub-section should begin with a lot of diagrams identifying engine parts. Then, it should have a section entitled "REMOVAL". It begins by unplugging all the wires attached to the engine...I highly recommend some kind of effective labeling system.

Good luck, Stacey. Let us know how it comes out for you, If you're smart enough to buy a used engine for it, then you can do this...I guarantee.

P.S. You may want to investigate the "chemical reaction" diagnosis a little further before you pull your engine out. In all my decades, I've never heard of such...might be B.S. to steal a gal's money. It wouldn't be the first time unscrupulous male mechanics have preyed on the innocent.
