Super useful information. My wife's truck has this same engine, made life interesting with gasket replacement at 362000km but runs strong still. Just hit over 600000km in September and still runs great. Yes some of these engines can be a hassle, I guess it depends on what kind of life its had and build/repair quality it underwent will determine most major issues. We pull 3000lbs quite often and do lots of uphill driving and haven't had much issue. Won't do it forever and she is getting old but it is a good engine for us.

I love the new text color! This write-up is hella helpful. I have run into all of these problems prior to finding this thread, I am glad i'm not the only one (and i've seemed to approach each the same way recommend). Also everyone, our powering steering pumps DO NOT take power steering fluid. huge mistake i've made. Thought it should be added for newbie techs like myself.

I build a lot of 3.0 engines for people and block condition is a problem if maintenance is not done on schedule. Toyota themselves recommend the green antifreeze. Engines with cast iron blocks have been used since engines were created an pose little problem if coolant is replaced on a regular basis. What you have here is a cast iron block with aluminum heads which causes problems with dissimilar metals and intergranular corrosion. All cast iron blocks will corrode if antifreeze is not changed. Even worse is that the aluminum will corrode as well.
Your best bet with these blocks is to flush and change the green antifreeze every 1 to 2 years and if still worried about it then run a sacrificial zinc anode in the radiator. You can buy a radiator cap with a zinc anode connected to it.
The Toyota red won't fix a system that has already corroded.

Question VF1A transfer output shaft

I'm in need of an output shaft(mine is bent) for a VF1A transfer case out of my 94 Runner. Anyone know where I can get one? Also need a rebuild kit for this transfer case do they have one anywhere?

Even though you are hijacking this sticky thread, I will respond.....

Where are you located?? I have a low mile VF1A in good condition I might part with.

Apology

All,
I apologize not sure how this happened, It was not my intention to do so. I'm at a loss to find a good output shaft. I'm located in Sioux City IA, 51106.

I wanted to say thanks for the informative sticky. I've checked it out a couple times keeping my 91 4runner going and it's been great!

Output shaft

I am not familiar with that part number. Is that the out put shaft for the automatic or the manual? I have a complete transfer case for an automatic if that is the one you need.

Some great tips

Bought my '94 3.0 4Runner in 2000, with 98k miles on the motor (after previously owning an '84pu, '88pu and '89 4Runner). We call her the Black Pearl. Through the years, I've done much of the suggestions/tips in this thread. Lots of upgrades done for off-road and performance, too. She went to 379k miles before the dreaded head gaskets went again in 2015 (for the 4th time!) and cracked the upper block. Got a re-manufactured motor and was on the road again. Gone through all the heartaches of all the HG issues, and thought I was done with them, since I've done so much of the suggested maintenance, mentioned here. Damn, it it didn't happen again this weekend! Guess whoever rebuilt that last motor, didn't find the "new and improved Toyota head gaskets" to put on. Geez. I've got 420,500k miles out of her...thought I could hit the 500k mark. "Oh, what a feeling, Toyota"!...right? Wife is bugging me to get to get rid of her. Gonna miss the Black Pearl.
