rev up your engines, today I'm going to
talk about a vehicle that has strange
problems when you start it up and listen
under the hood you can hear that first
metallic sound now I'm not talking about
the noise that's as evil swine's are
making all day long in the background on
my video I'm talking about that
metallic rattle you heard once the
starter engaging and the engine action
start and the other odd thing is when
you corner fast on this sometimes the
oil pressure light comes on even though
the oil level is perfectly normal at the
full so it's not low on oil so I got to pull it in the driveway and check it out and when
you look under the hood you can see this
has a 1 AR FE engine here it is it's a
four-cylinder engine and if you do a
little research you'll see that the
engine has been known for reliability
but it has one main problem the variable
valve timing system has a tendency to
make a knocking sound on cold start ups
now you heard that first knock watch
what happens now that it's already
started up
now the only thing you hear is a little
valve rattle it's got a hundred and
thirty thousand miles but you don't get
that metallic on the first startup
because the variable valve timing system
ready as oil pressure in it it only
makes that noise when you start it up
cold but I do have to say the oil is
really dirty so I'm going to change the
oil and filter run some quality oil on
it see what happens so I can jack it up
in the air so he can change the oil
and stick a jack stand for safety then
got an oil drain pan it's often hard to
get the oil drain bolt on and off I use
a long extension bar and a socket then
it's easier to pull them out and get
them tight without wrecking anything as
you can see with the long bar when you
pull in a long bar it's a lot easier to
get them off then we can get the rest by
finger then out comes the oil it's
really dirty and if you don't want to
have future problems get a new gasket
for the oil drain plug these things only
last so many times they don't cost much
so buy them before you change your oil
then you're not hunting around to find
one if you only have one car you can't
drive it so I package I buy these on
Amazon I buy packages like 10 then I got
ten of them and I know I'm never gonna
have to worry about having a problem
leaking or stripping because it's got a
nice new gasket each time and they don't
cost much now when you do put it back on
this is where the giant extension works
best because once you get it on you can
easily at the other end push it so it's
nice and snug it won't be too tight but
it'll be tight and it won't leak now you
got to change the filter too but
unfortunately this is one of these swine
designed paper ones where there's a
plastic container it hides inside you
have to have one of these metal tools to
get it off it fits on and gets it off do
not buy one of those plastic tools
they're crap they'll break get a metal
one like this this particular one is a
vim solid metal look at that this
is not cheap it will last as you can see
your snaps right on nice and tight then
again look and here's our extension bar
because these things can be hellacious
pulling them off
as you can see now it's turning it'll
come off and down comes a whole assembly
which will take off then you get the new
filter and it just goes inside pushes
right in and there's an o-ring here you
replace the o-ring
luckily the SDP oil filter the kit comes
with a new ring just go a little pick
slide it under get the old one off and
then slide the new one on it goes on a
last groove get a little better the all
going on push it around so it slides on
nice and doesn't stick now if your spins
on and get your socket keep turning took
it snug now it's tight and it won't leak
oil it takes about four point six quarts
of oil pour it in slowly because these
Toyota's don't take oil fast they have
baffle plates and if you pour it too
fast you're gonna get oil all over the
exhaust and it's gonna smolder now I
love these giant jugs cuz they got a
little clear part and since we're
putting in 4.6 it'll be a little less
than half a quart left so we'll do it
till it gets down to here
a little bit more then we'll start it up and check it and whatever you do don't forget
to put the cap back on
I've had people leave the cap off oil
gets everywhere can ruin stuff make sure
you put the cap back on and don't forget
to get rid of the jack stand cuz if you
drop it with a jack stand you might Bend
something now we can let it down that'll
start her up
another one off of my five minutes and
if you notice compared to what it was
doing before the overall engine is
somewhat quiet too you don't hear the
valves clacking as much it's quieter than
it was this is why I have to keep
beating people over the hat to change
your oil regularly you don't want to
ruin a great engine like this by having
dirty oil running low on oil I had a
customer a few months ago bought me a
Toyota Camry had the same engine sounded
like it was falling apart she only had
half a quart of oil left and she said
well I had to change six months ago I
said did you ever check it and she said no
her car at 140,000 miles it was burning
on a little oil she never checked it so
please change it regularly, me on this
particular vehicle I change it every
5,000 miles with normal stop and go city
driving you don't want to ruin this
beautifully designed 2.7 liter
four-cylinder engine because the oil is
either too dirty or gets low that once
you shut it off wait about a minute then pull
off the dipstick and check it in this case it still needs a little bit more
you can't always go by the
specifications that a computer gives
that's why you check it so we're gonna
put the rest of the total 5 quarts in
then turn it off
and wait another minute for to drain and
check it again and now it's perfect it's
on the second dot which is full between
the top top the bottom dot is one quart
now it's full and this is another reason
you'll want to double check your work
you can't always believe the data I've
seen them off sometimes as much as a
couple of quarts the dipstick works
correctly always go by the dipstick
reading on level ground after you warm
it up and then shut it off and let it
sit for a minute or two so the oil
drains down you get the correct reading
now I'll take it for a spin
hey that's running quite smoothly and
guess aht a lot of that noise that's
gone you can hear a tiny bit of valves
but hey that's normal for a car with
over a hundred thousand miles let's look
under here
we're cornering the oil light is not
coming on like it was before fix and
maintain a well-built engine happens to
be making some odd noises you didn't
hear before and here's some bonus
questions and answers 18:08 saysScotty
please help I got 2010 Nissan Pathfinder
v6 50,000 original miles I got the
battery place now my car won't start
doesn't click or anything the battery
terminals are clean I don't see any
blown fuses help odds are your
anti-theft system is locked itself in
and the reason I won't do anything cuz
you turn the key the anti-theft system
is stopping it from starting if you have
a remote somewhere that works go get it
lock and unlock it lock it unlock it
sometimes that'll fix it here is a trick
that sometimes I've seen if you don't
have the remote anymore something's
wrong with the system this will often
work disconnect the battery for a couple
of minutes before you reconnect the
battery put the key in the ignition and
put it to the on position not start but
on where the lights would be on they
won't come on because you got the
battery disconnect with the key turned
on then connect the battery and
sometimes that can fool those anti-theft
systems because it sees that while the
ignition key is turned on so therefore
the key is in the car and not a little
start the car and if that works great
live with it that way if neither of
those things work find a mechanic like
me we get on our fancy scan tools we
plug them in and we first check to unite
that system and sometimes something just
breaks and it sounds nuts but sometimes
just replacing the battery in a car
finishes off something in an anti-theft system and
when you put the battery cables back on
in a system there could be a little
power surge or a spark and it can finish
the anti-theft system off but trying my
systems to fix it first because a lot of
times you got a remote that'll fix it or
disconnecting the battery for a couple
of minutes to turn the key on put it
back on
then it'll start again I seen that work
many times curt says I'm looking to buy my son an 08 Lexus
is250 has over two hundred thousand
miles the guy wants 4500 bucks it's a
one owner car severed man right next
well first I would want definitive proof
that he's the original owner of the car
that's two hundred thousand miles and
it's an 08 that tells me it's
probably a lot of highway mileage
highway mileage as I told millions of
times its equivalent to 10 percent city
miles so say that was all two hundred
thousand miles on a highway gotta be
equivalent to 20 thousand miles stop and
go driving in the city the guy wants
forty five hundred bucks but that's
200,000 miles on it and is 12 years old
I would try to pay less myself
regardless of it's a one owner car
two hundred thousand miles is two
hundred thousand miles most people don't
want to touch a car like that they're
not gonna get any guarantee I would try
to pay less for the vehicle if you have
a mechanic check it out and he says
everything's fine that's okay and he
says yeah it must have been a lot of
highway miles you know cuz it's an
excellent shape go ahead and buy it
you're buying it for your son
forty five hundred bucks for a car that
costs ten times that when it was new
what the heck you know for mechanic says
it's okay it still could be a good car
I'm just cheap I'd pay a lot less, so if
you never want to miss another one of my
new car repair videos, remember to ring that bell
