I took it to a dealer and they told me that i had a head gasket starting to go bad that let coolant into that cylinder after i shut the engine off resulting in a rough cold start. The tech specialist gave me some nice information and after research i learned toyota knew about the faulty head gaskets in their vehicles and came out with a new redesigned one, but they never…

    Blown head gasket at 150k miles. Potential to overheat to overheat while in operation leaving the passengers stranded or start an engine fire. Every local mechanic shop i received estimates from in knoxville was very familiar with this issue for this model year and the internet forum searches have hundreds of complaints for this same issue. No recall has been issued for this problem.

    Loss of coolant with no visible signs of leaking. Replaced so many things and keep getting misfires and vsc lights on constantly. Rough start up for about 30 seconds every time started. Slight over heating if idling ... All points now lead to blown head gasket in which i read more and more and common with 04 v6s.

    This 2004 toyota 4runner had 145000 miles on it when the check engine light came on, along with vsc and vsc trac lights. Engine ran rough/rumbled for few seconds after each start, then the rumbling would stop. At autozone they diagnosed a p0306 error code. Took it to the dealer who scanned code # 0306 #6 cylinder misfire. Further testing showed coolant seeping under headgasket, and dealer recommended replacing…

    My 4runner check engine light came on and the vsc trak off lights came on with it. The trouble code indicated #6 cylinder misfire. After checking all the sensors it became obvious that there was a slight loss of coolant. Checked the engine and found that the head gasket for #6 had failed. Looking on line i see that there are hundreds of complaints about similar problems around the 120k miles mark. Isn't toyota…

    Cylinder 6 misfires caused by oil leaking into cylinder 6 combustion chamber around spark plug. The issue is traced back to a head gasket failure on the 2004 4runner v6 engine. Cylinder 6 is the weak point where such failures occur especially at start up and when the engine is cold. There is clearly a design flaw in the 2004 v6 4runner's head gasket which requires many hours of labor to repair and should be covered…

    After reading online there are hundreds of reports of cylinder #6 failing with a head gasket issue which results in a 2500-4000 $$ repair bill. Toyota had a major recall for the 2nd generation 4runner because of head gasket issues. They really need to address this issue b/c there is obviously a major problem with the 2004 4runner v6 engine. *tr

    Rough idle at morning start up. Vsc, trac off indicators illuminate. Obd ii code of p0306, misfire cylinder #6. Having to refill engine coolant on a weekly basis. Premature head gasket failure. Toyota super long life engine coolant is slowly leaking into cylinder #6. Rough idle noticeable at morning start up because the fluid builds up to a considerable amount overnight. Estimated cost to fix is $3000. *tr

    Engine is leaking coolant into the #6 cylinder causing misfire, rough idle, and check engine light to illuminate - apparently a very common problem with this v6, 4.0l engine leaking at the #6 cylinder - obviously a manufacturing defect to have head gaskets failing at the same location. *tr
