Trade in my V6 for a V8 or sink $$ into the 6?

Small detail, I said 50% more, which is not double. Our V8 gets ~14mpg. 50% more is ~21mpg, which I understand is possible by some V6 owners which I consider to be sane & otherwise reasonable people.

Double would be ~28mpg. Only car-based or diesel SUVs are going to stand a chance at approaching this.

Now, if you consider ~14 to be way too low, I'd like to know about it, because quite frankly I wasn't really prepared for the amount of fuel this thing drinks.

if yours was a v6, and you drove it the same, you would be getting about 16mpg. NOT 21.

I get 16-18 with my v8....
 
FWIW i get 18-19 city and 20-22 highway dependent on load, hand calculated, not from the dash display

exactly. that's with the v6. I get 16-18 in town with the v8. not sure on the highway, as I don't travel far very often.

my point was just that if hes only getting 14 with his v8, he cant expect to get 21 with the v6. his driving style wont allow it.

oh for sure. if I'm driving like the elderly i get those numbers. if I'm in a hurry somewhere I'm definitely getting anywhere from 15-17 at best. your foot determines your mileage more than the number of cylinders you have, and on 4runners the full time 4x4 vs selectable 2x4 is negligible
 
This isn't a valve cover gasket, it's a head gasket, the one between the valve head and cylinders. You need to completely disassemble the head including cams and all associated parts, and pull the exhaust headers. The book value is 20 hours of labor. This mechanic needed 8 entire days to do it:

Well yes, I understand the difference between a head gasket and a valve cover gasket, which should be clear in my post. I think a lot of people consider removing a head/heads on an overhead cam engine to be voodoo. It's not that much different than a cam-in-block engine, which is fairly easy. And yes, I've done it before (multiple times) on Ford modular V8's, both SOHC and DOHC (current GT500). Just doesn't seem like that big of a deal, and given the cost of paying someone else to do it, I'd certainly tackle it myself.

And the mechanic that required 8 days to do it should go back to serving Slurpees at 7-11.
 
I have only had my V6 for about 8 months so far but it seems more then adequate for daily use & based on my experience towing a 6X12 Uhaul trailer packed full in the past with a Tacoma & same engine I'm going to say it's up to the task to do so. Is it going to be fast? Heck no, but it will do the job easily & I think the only one's NEEDING the V8 would be the one's towing a heavier amount OFTEN. Sure the V8 provides more torque & sounds better but many ppl get the job done easily with the V6 & save mpg in the process. The V6 in this truck is very capable & for most ppl will get them where they need to go without any issues. I'm not an advocate for either but based on my experience both engines are well equipped for your needs.
 
I'm willing to bet that my v6 with long tube headers and intake could pull just about as much as the v8 could. Its surprising how well the v6 responds to upgrades.

Are they actually worth it? I'd like to add pep to the v6 but it seems like nothing short of a supercharger would make a noticeable difference
 
No. At some point you can't compete with pure displacement. A larger displacement engine is by fact of reality going to be able to pull more torque than a lower displacement engine.


You can add all the gizmos and scam chips and still run to to the hard truth. That is why a v6 with a high HP will still usually have a harder time towing than a v8. The power curve and torque profile can't match a larger displacement engine.
 
V6 will never sound like a V8.
V8 is a dying breed. Thanks to the man.
Tree huggers hate big bad V8's unless they need one(tree) moved or their trailer pulled.
 
I think its worth it. I noticed a huge difference with just adding headers. I have larger heavier tires than stock, and I still have tons of passing power. And plenty to tow anything a 4 runner should be towing. Yea the v8 would be nice, but I like getting a little better mileage. Plus maintenance is cheaper on the six. Not to mention there are way more out there.

I never drove the v6 4th gen. Having the v8 I dont think I would like the v6 much minus the bit better MPG. Its not like the V8 hauls like a sport car. the power band is a smooth torque and hp wise. I was expecting it to me close to my past x5 v8.

As for maintenance. you are paying for 2 extra spark plugs. Also people fret about timing belt and water pump change, and this is with many vehicles. Its time consuming but its like any other service, and only every 100k miles. I rather do a belt change every 100k than a chain change every 250k. However I never kelp vehicles that long Sigh.. Hopefully this one keeps me occupied for 5 years, but I doubt it.

one of the biggest reasons that theres still an ongoing debate between the 4.7 and 4.0 on this forum at least, is that the power band, while no identical, is very smooth and steady for both motors. lots of low end torque from both motors
