Head gasket issue for 2004 4runner V6 (a thousand time)?

Ok folks, i guess i must be number one thousand something who is reporting to have a head gasket problem. I tried to post as a reply to another thread but it didn't go into the system.

My car: 2004 4runner SR5 V6 (1GR-FE) 2WD. Bought it brand new on Jan 2004 and have over 155,000 miles on the car. The car has been flawless...until last week. Never tow and just simply using this as a commuter car to/from work. Gas mileage is the only complain of course.

All 3 lights (engine, VSC and trac off) and engine code P0306 was thrown one morning. The car vibrated violently in the 1st 15 seconds but went away after the car was warmed up. My car was way overdue for spark plugs change so that is what i had my mechanic do. A new coil has also been replaced (misfiring on cylinder 6) was reported. After 2 days of normal experience, the lights came back on again and that is when my mechanic suspected about the head gasket issue. After running the color radiator test, it was confirmed (yellow color which shows gas leaking into the radiator). After i got a big quote for the fix, there's when i hop on to the internet to find hundreds of reports about this issue dating back to as far as 2008. The issues affect mostly 04 4runners with V6 engines. My mechanic has done work on a FJ cruiser a few months back so he has seen this before already. The symptom is the same as what others are experiencing here.

Contacted Toyota customer service to report this case. No recall or repair assistance was offered. My case # 1309061140 was recorded. Only 4runners from 88 to 93 were on the recall list. So i am on my own.

Quick question, if i fix the head gasket issue (which i have to do whether i keep the car or not), will I be required to do this again sometime in the future knowing that it is a design flaw? I have seen reports of this with engines around 90K.

What else should I replace while everything is being taken apart for this big job?

No you will not have to deal with this again in the future. If you go buy a new head gasket from the dealer it will be redesigned. So the new head gasket apparently fixes whatever flaws and premature failure the old one has.

I would get the heads completely rebuilt. Have your machanic take your heads to a machine shop and have them reseat the valves, resurface them, pressure test, etc.

You should be good to go for another 200k+ miles.
 
The head gasket job will cost around $2k to do this. We also saw a little leakage in the bottom front of the engine (water pump issue possible) so we will do that as well. For the last 9 1/2 years of ownership, it has been troublefree so far.

I am not sure how much more resurfacing the valves are going to cost. I will find out next week. I guess if the head is already out, I might as well get that handled.

Anyone here have a 4th gen with a V6 engine that has over 200K miles without having to do the head gasket? I am just curious. My other car that i sold (Camry Solara V6 with the 1MZ-FE) had over 265K with no issues other than leakage from all of the seals.
 
[MENTION=46138]chmura[/MENTION] is right. The head gasket has been redesigned so you should be good to go. When/IF it fails again, your rig might have well over 350K miles (will you still have it?)

$2K for a head gasket fix sounds pretty good in my book. I've seen quotes in the $3-4K range. Also good to know you reported it to Toyota, if enough get reported and someone makes some serious noise, they MIGHT issue a recall.

IMO, I'm still not sold on the idea that there is a widespread problem with the headgasket on our 4th gens.

Sucks to hear that you have this problem, cool to know you aren't "throwing her away". Sounds like your truck is still solid.
 
Guess I'm one of the few that hasn't had a head gasket go. 265k going strong, coolant sits at 190 even during hot Texas summers. I've towed full size car haulers out of state and off roaded my share, I do not baby it. My 1GR has been good to me.
 
2004 4runner head gasket victim

Called Toyota to report and they told me there is no alarming amounts of reports on this problem with this vehicle, none to my representatives knowledge. Hmm? . 153,000 miles . Consider myself lucky to have found it leaking and not completely shot? no rough start, loss of fluid at gallon a day, heat off/on, no power loss or mileage affected.

Very angry and frustrated..2004 sr5 4runner well maintained now sneaky head gasket

I dated a gentlemen that purchased this 2004 sr5 4runner brand new.. oil changed every 3000 miles very well maintained. He told me a year ago his trac lights and o2 sensor showed at sametime that is what he was told.. this thing was so well taken care of he assumed it needed it's first tune up at 150,000.. Well reason he told me all this since broke up in our relationship about 1 month ago my 21 yr old daughter he helped take care of was given this very nice gold 4runner! I immediately took it in for tune up and to check everything! To only be disappointed that no4 cylinder had condensation! And that is why the lights are on trac etc.. check engine.. told it wouldn't do any good to change 02 sensor because it was some sort of heater communicator o2 sensor.. and will be out till head fixed... wow he is frustrated, and you'd habe to see how well maintained this vehicle was kept up! I haven't took it to dealership yet to complain and wondering from reading everyone else s forum if it would matter... any suggestions would be nice to do but unfortunately hoping to find and honest mechanic that fixes it right.. my understanding it's just a small drip it's only misfiring at moment! But I need to fix asap my daughter has autism and panics.. not good for something that can just tear up ( what if my daughter thermostat locked up and really ran hot and she panics and stranded on road) that kings of scenerio.. any suggestions would be nice! Thank u

I have an 04.

Just hit 200,000 a few weeks ago.

Still going and no head gasket (knocking on some serious wood right now!!)

Hey chmura. I've been doing research and I'm still finding old part numbers for sale on oem retailer sites. Is there a way to confirm that the parts have been updated or can I use a parts for a later model like 07-08?
