rev up your engines, marky mark, Scotty when I fill my honda
cr-v the pump always stops filling, even though it seems like the tank isn't full
is it okay to add it after the pumps, no it's not modern cars have what are called
EVAP systems, it's an anti-pollution device so that
fuel vapor doesn't pollute the atmosphere, when I was young mechanic
they didn't have that, they just had gas caps and when it got hot and the gas
expanded inside the gas tank, it would just vent out fumes, well now they have
evap systems, and if you have the automatic pump at the station stop
pumping, and you keep squeezed more in, you can end up pumping raw gas into that
EVAP system and you can ruin the EVAP canister, some of these evap canisters
are under the gas tank, you got to drop the tank to change them, they can cost you
seven or eight hundred dollars to swap those things out, so don't do it, now if
you've got a 66 Mustang or something it doesn't really matter, because they don't
have all that crap on them, but all modern systems have them, flater and flater
says hey Scotty I'm thinking of swapping my 2016 Mazda 6 GT for the 2019
Kia stinger, I'm not sure if it's a good idea or not, what car do you recommend
you're talking about swapping a three year old Mazda GT and getting a brand new
Kia Stinger, you're gonna lose your shirt, when you buy a sporty car and you get
rid of it when it's three years old, you're gonna get nothing for a trade, now if you
don't mind that, go right ahead it's your money, the Kia stingers are kind of
interesting fast little cars, and the Mazda 6 GTS are kind of fast little cars
if you don't mind wasting all that money and you want to do it go right, if you like
driving them, go road test one, you really like it go right ahead, but
realize you're gonna lose your shirt if you buy another car every two or three
years, in my father's day you could get away with that, cuz the new cars were
only $1000 and you'd get 500 bucks trade in and pay a thousand for another
one you weren't losing that much, today you're gonna lose your shirt doing that
I'd say if you're gonna do that kind of stuff buy them used,
save yourself a lot of headaches that way, a lot of money too, pig pen and pig pen
says Scotty I'm looking to buy a used v8 f150, I want to do a muffler delete and a
cold air intake and a supercharger for more performance and better miles per
gallon and larger tires, what do I need to do and is
it a good idea, no it's not a good idea,
you know unless you're talking about a real old one that had a carburetor on it you
can do whatever you want then, because they're easy to adjust, but modern
vehicles are all fuel-injected, and if you do all that stuff, you're gonna have
to pay a real pro to reprogram the computer and if you're gonna do a
supercharger, you're gonna have to rebuild the engine because if you
supercharge a used engine, odds are it's gonna blow it from the extra pressure,
you're getting into you know expensive things, if you remember the original
road warrior where he's in a junkyard and the guy's got a little sign behind
him and it says, speed is just a question of money, how much do you want to spend,
it can get very expensive doing that stuff, and for some little vehicle like
that if it's an older truck I don't know if it's worth the money doing it, those v8s
got plenty enough power the way they are now if you want to really fix it up and
have fun and spend a ton of money, go right ahead you can have fun with it,
just realize you can't just buy stuff and bolt it on and drive away, modern
vehicles don't work that way, Steven Crowell and Steven says, what are your
thoughts on the Datsun 280zx okay those were great sports cars back in
the day, Datsun was the first company really, now it's called Nissan, to make a
reliable fast fun to handle sports car that didn't fall apart and cost a small
fortune, they sold a lot of those things those were really fast, they turbocharged
some of them made them even faster, they were great in the day, now the problem is
they're really old now, and I get some customers buy the old ones and decide
they're gonna do them over, now you have to realize that, as old as those are, a
lot of times they're gonna have to do the wiring over, do the computer system
over, it can get very, very expensive they were great cars in the day, they
were really an innovative sports car that went really fast, out here Scotty I
got an 85 v6 2.8 Fiero, it's not working before it stopped it started making some
popping backfire sounds, go on the freeway at high speeds the transmission
wouldn't shift right, those Pontiac Fiero there were bizarre cars, they had the
engine in the back but they had the radiator in the front of the car, they
almost all had overheating problems cuz the front of the car was pointed and
since the radiator was there, it's at an angle and it had fans, and if the fans ever
broke, it wouldn't suck enough air and the engines would overheat and blow
the head gaskets, those things are so old there's a zillion reason that they can
pop, the first thing you want to fix is the popping, now it could be ignition
coils are bad, it could be the engine starting to blow a head gasket, could be
a lot of things, you want to test the compression first see if the engines
worn out, if it's not that check the ignition system, that's often what makes
them pop, and you can also check the timing chain those things had timing
chains in them and if those timing chains stretch, then the timing gets off and
that'll make them pop too, you can check that with the time light, those are the
first things I'd tell you to check, so if you never want to miss another one of my
