Blown head gasket at 65k miles

[Atticus]

Good to know if any 100 series owner has a comment about a 80 series they are required to post it in the 80's forum so the comment can be "approved" if not they are a ball less coward???

Well, landtank can fight his own battles, but I find it irksome when people don't know what words mean. Look at Landtank's post, and what he actually says. Then look at your response to his post. Then realize that your statement and Landtank's statement have very little to do with one another. If unable to realize said disjointedness, return to high school and relearn English. Repeat step one.

Or, I'll save you the trouble by pointing out that Landtank's post didn't say anything about pre-approving a comment on the 80's. Anyone can have an opinion on the 80. Here's one: I hate their fender flares. That statement has not been pre-approved, but I'm pretty sure Rick will let it slide.

Cheers,
Jay

Exactly.

Exactly.

Where was the coolant leaking? Was it dripping down? Were you getting white plumes of smoke from the exhaust? Find it hard to believe that you have a blown gasket at that mileage. A 2nd opinion may be in order.

I second the second opinion. This is the first head gasket leak I've seen reported on this board. Has the anti-freeze ever been changed according to the maintenance records? Open the radiator cap and see if it has the Toyota red anti-freeze. Stick with the Toyota anti-freeze and change it every 30-45k miles. If the leak is anywhere near the front of the engine, I'd suspect the water pump or the water inlet housing o-rings or hose connections. There are two drain valves for coolant on the engine that coulod leak but both are on the driver's side. Anti-freeze also flows through hoses to the oil cooler loacated where the oil filter screws on. There is also a bypass hose. If your up for a DIY inspection, remove the front under side splash pan and look up from the bottom to pinpoint the leak location.

Hey Jimmy, next time you have a comment about a posting in the 80 section show some balls and respond there.


The comment on reliability was centered around the fact that the government outlawed the use of asbestos in HGs and that large displacement engines were more effected by this because of their size and all the manufacturers where scrambling trying to redesign a substute material. Your 20 year old 22RE doesn't meet the criteria for comparison as it is a small displacent engine with an asbestos HG.

You have a point there, Rick. The '90-95 3 liter V6 4runners were so notorious for blown HG after toyota switched to non-asbestos HG's that toyota offered to replace the HG's free provided the vehicles had < 100K mi. I have heard that Toyota volunteered to switch first while domestics flat-out refused saying they couldn't re-design their HG's in time. Well, Toyota's decision showed pretty quickly in the 3 liter V6. Maybe that engine had less tolerance for HG faults (the '88 4runner V6, the first year the V6 was introduced, didn't have any HG problems). However, the HG problem was fixed after '95 with the introduction in the '96 4runner/taco. Yet, we see '96 and '97 LC's blowing their HG's, when Toyota at least had the HG material problem/know-how fixed by then and the problem fixed in the 4runners. Why would they continue to use suspect HG's in LC's for another two years? That just doesn't make sense. Maybe they figured the 1FZ was robust enough so the HG's wouldn't blow until after 100K mi (and by then, warranties have long expired), or a number of a multitude of reasons. BTW, how are HG's holding up on overseas 80's?

In response to my 22re HG replacement, the timing chain/tensioner was being replaced at 120K as PM since at that time, it was my sole vehicle and I didn't have the $$$ to get the LC for 5 years. Since that was also my road trip vehicle (we'd take lots of trips to Death Valley and isolated locales like that), I didn't want to take the chance of hearing the timing chain rattle of death hundreds of miles from civilization, hence the t-chain replacement. The mechanic who did the work said he'd pull the head (FSM recommends to pull the head, but one doesn't really need to do that), hence the new HG. I also had a TRD cam, header, and enlarged exhaust installed due to major lack of power after installing bigger tires & OME lift. I have a co-worker who has a '87 w/ close to 300K mi, original HG, and he drives 90mph all the time. But again, maybe that's the asbestos advantage!

Anyways, back to the main thread, a blown HG on a 2UZ is practically unheard of, unless the PO didn't maintain the cooling system at all or mixed red and green coolants, used tap water, etc.

I'll point back to post 16 regarding the maintenance & what's apparently wrong.

Also, you mention mixing red and green coolants, the toyota service advisor who was a tech for 15 years said that was no big deal. Anyway, I can't argue one way or another, that's just what I was told.

Jim_Chow, my understanding on the 3.0 V6 engines was that there was an issue with the shape of one of the exhaust manifolds and it causing a heat issue on one side, but since I don't own one I haven't really investigated it.

On the 80, the 1FZ-FE was slated for 1991 production but was held off until 93 for whatever reason. They might have just gone with what they had. At some point during developement you just have to pull the trigger and release a product, and deal with it's short comings later.

No doubt though, the HG failure rate is really picking up some STEAM .

FYI for everyone, the head gasket problem for the 4Runners and trucks was not fixed in 96. It was not quite the epidemic of the 90-95 but there weren't as many units on the road yet. Failure rate of these early engines (5VZ engine V6) was pretty high. The difference was the newer ones, the HG would crack and leak coolant externally, 90-95 was an internal leak.

I know somebody might ask this - most of the 5vz failures were very low mileage, less than 30k, If you have one with high mileage your fine.

So while you may have thought Toyota had there HG solution the did not.

My insight - I worked at Toyota when the 90-95 recall came out and we were getting pretty tired of doing the HG (I like fixing things - not working on an assembly line) on those older vehicles. Then we had about 5-6 5vz engines come in one week all with leaking gaskets, we all thought oh shi* here we go again on the next generation none the less.
