I don't think he's saying that a GOOD cat is at fault, more like a cat that is 17 years old and clogged up...


Metal shavings are from the reciprocating saw




O2 Sensor

I definatly know I will be putting a high flow cat - back system on...

BTW those 17 year old cats are worth lots of money at the scrap metal recyclers.

that's why all the crackheads cut em off! lol

and i'm glad my exhaust system is getting freed up, no cat (O2 sensor BEFORE the cat, so it shouldn't read abnormally if i remove the cat.)and NO MORE CROSSOVER!!!!

i'll be starting a thread on that soon too

*EDIT* actually instead of starting a new thread, i'll just post it in my 3VZ REBUILD thread..

Awesome camo! I want to get rid of the crossover too, but might have to just keep everything stock until cash is in hand for the project.

id guess yes.

i know i do. but i also perform all the maintenance, so failure time is exteneded.
i dont just turn the volume on the radio up!

the last 22re that had a bad HG, i drove till it died becuase i knew, and saved for a replacement.
same w/another motor. got ~10kmi from a motor that sat for 10 years... w/a little love



the only other option is to replace it every couple years, in lieu of(or prior to) required maintenace.
id rather pay a '1 time' maintenace bill than a new car payment, which has devalued once the tires hit the hiway.

I would sell it directly to the metal recycler, the junk yard is an extra middle-man.

Thats pretty much what I meant. I know I probably misuse the terms "junkyard" "salvageyard" and "scrapyard" sometimes lol.

So I'm cleared on ordering the rebuilt longblock by my bank (took out a small loan) And I'm calling Oregon Engines to have one of their Super Stock VeeZee's sent my way!

The one I found here takes lots of scrap metal like copper, aluminum and cats, I don't know what else. They were very busy and rushed me out pretty fast (with cash in hand ) In a bad area of town and lots of bums with shopping carts bringing in stuff to sell.

Next time I go I'll have to take some pics, it was quite a sight LOL.

Got my 3VZ-E Super Stock the other day - started a thread: https://www.yotatech.com/forums/f116...thread-211659/

btw - got $163 for my old cat - I think that just about pays for the whole new exhaust (minus headers - which I'm not doing)

And oops! Look at the damage to the head:



A pic of the same area on the gasket around #1 shows evidence of severe crushing - the kind that comes from a head that overheats and expands excessively, crushing the gasket:



It looks like these are the redesigned slipperplate gaskets that toyota used in their service campaign gasket fix. And it looks like they may solve one problem and introduce another. Since I used these gaskets when I replaced mine in 2001, I'm wondering whether they're going to fail in the same way. I have a little over 60k miles on mine, and its still running fine. Haven't done a compression test lately, tho.
Interesting. I've posted somewhere on here before that I believe the 3VZE is very sensitive to overheating. I had my gaskets replaced in 1997 as per the recall campaign. In the early summer of 2004, those small coolant transfer hoses on the intake manifold decided to blow at different points so a few times it got really hot. My bad, as I didn't pull over right away (I had good reason). The driver's side gasket (at the #6 cylinder) let go eight months later, costing me 1500 bucks.

I just came across this thread, sorry so late. But I also had the original head gasket from the factory on my 88 3VZ-E fail in the same spot on the #1 cylinder with ~218,000 miles on it(a testimony in itself to the supposed predisposition of the 3VZ-E to HG failures...yeah right!). I just wanted to put this pic in here to add to the evidence being gathered of such occurances. There was a corresponding ding in the #1 piston too. Just no pics of it, sorry.
Mine.

Yours.


Notice on mine the pre-slipperplate design of the first OE Toyota head gaskets for this engine? Makes you wonder why they changed their minds on that. That one lasted ~218,000 miles/19+ years.To answer that question, they didn't really change their minds of course, but rather were forced to change the gasket material from asbestos(like my 88 had)to graphite, after finding out what a mistake that was they then switched to the slipperplate version. So in reality it was entirely due to the 2nd design revision(asbestos to graphite)that lead to the 3rd revision(graphite w/slipperplate). Blame OSHA for the whole fiacso, because that's what really happened.

BTW, try using some SeaFoam every once in awhile. That sucker looked NASTY!!! See how much cleaner mine was from doing so on a regular basis.
