The V6 vs the V8
I was recently told by my friends, 2 of them are mechanics, that V6
engines run perfectly for a while and when they break down they cost
more to fix than a V8 or a V4. And they aren't too reliable after a
This is the kind of question that has no real answer because it is
trying to compare apples and oranges. Most V8 engines that have been
marketed in the last 10 years are overhead valve push rod engines bred,
born and built in the USA, the V6's during the same time are probably an
even mixture of push rod and overhead cam engines from every country in
the world some very good some very poor. The small block Chevrolet
engine has evolved into a very dependable good performing engine, that
with fuel injection lasts along time and when it is rebuilt it is by far
the most reasonable priced parts wise of any engine in the world and in
this same thought most American built V8 engines are good values. The
V6(non overhead cam) on the other hand is "almost" as expensive to build
as a V8.
The overhead cam versions are "much" more expensive as most of these
engines are built in Japan and Europe by a multitude of manufacturers.
All foreign built engines no matter what the manufacture are twice as
expensive as their American counterpart - check out the price to rebuild
a 4 cylinder Toyota engine like a 22 RE which is very popular. The 3800
Buick built V6 which was originally designed in 1961 and has probably
been sold in more cars then all the other V6's combined, is still
reasonably cheap to rebuild, usually goes wellover over 100,000 miles
before requiring anything major and therefore disputes the 2 mechanics
opinions. As far as I know the V4 that is referred to is one I have no
knowledge of as I think SAAB was the only company to market this
configuration and I'll guarantee that it is very expensive to maintain
let alone rebuild.
