2005- 2006 v6 head gasket issue

New member but long time visitor with 05 prerunner. Im starting to see more and more members posting about head gasket issues on the early 2nd gens. Can we get a poll going with some type of mileage/year of members with and without this issue? Also can we get a little indepth on the type of oil used (including how many quarts) i know it shows 5 quarts but most refill at 5.5 quarts. Sorry if this has been covered just trying to figure out if this is a serious issue that i have to prepare for. Also as @KenLyns pointed out. Coolant change out with mileage if possible. Thanks

 

06 with 99,700 no problems yet. but I got a feeling I will be doing some preventative maintenance soon. like trans flush and diff change with maybe a timing chain. I use mobile 1 full synthetic with a quart of lucas. 5.5 quarts total

 

Desertrunner24 i just turned over 65k and will be doing the same. How about your oil changes.. (how often? 5 qts or over as most say to do? Also what type synthetic or not? ) thanks for the info

 

It would probably more relevant to list the years/mileage at which the coolant was replaced.

 

KenLyns yes thank you. I knew I would miss a few things.

 

Good to hear no issues. Seems like it might just be a selected a few with the 05-06 headgasket issue. Hopefully they will post some of the preventive maintenance they did or did not do.

 

05, change head gasket somewhere around 160,000 miles.

 

There's little wet oil spot from corner of valve cover seal near dipstick . Got the truck last year the Milage is @167k running like champ.
Not sure what the previous owner did.

 

every 3k for me with 5.5 qts. synthetic

 

@libagui. 1 taco down. Any information on the maintenance on the taco? @Sae68 good deal! Thank you everyone for the information!

 

Oil change each 5000 miles just whatever 5w30 with correct service and SAE label. Never change coolant.

Mine is leaking at 138K. I don't think it matters when u change your oil or fluids just if its leaking and what mileage. Slowish leak maybe getting a bit worse. Right bank towards the rear

 

I didn’t want to start a new thread since there’s already a lot on this subject. But I can’t find the specific info I’m looking for. I’ve read that the Head gaskets were updated on the later 06 models. Does anyone know when specifically these were updated? I have an 06 Tacoma that was manufactured in August of 2006.

 

March/06 with 207k miles, changed coolant with Xerex Asian Formula, at about 100k.

 

Pretty sure mine is leaking. 03/2006 186k miles.

I have a bad idler anyway, thinking about replacing them all along with the water pump, and belt tensioner.

 

This doesn’t seem to apply to all 05-06. How many miles? Do you know the maintenance records? I Just changed coolant @70k with the oem toyota pink coolant. Original coolant still looked good. Currently at 72k. Also im bot aure when the updated gaskets came in. Hopefully someone can chime in soon.
