okay it's happen all of us we're driving down the road we got the AC on fresh air
not recirculate and we can smell a burning smell in this case it's an oil
burning smell smells like oil so what do you do you put on your gloves and get to
work now I've been wearing these gloves long before there's any kind of virus
attack cuz I'm lazy and I washed my hands and
it actually keeps you from getting caught sand chemicals on your hands so
these gloves are real handy let's open the hood see that smells coming from now
when you smell oil the number one culprit is a valve cover gasket which
then seeps down and gets on the exhaust manifold which is really hot and then it
smolders now in this case it's quite obvious cuz when you look closely you
can see oil is dripping down getting all over the place and that's what's
smoldering but if I learned one thing from my father hello I said when we were
fixing flat tires in the old Texaco gas station
check the whole tire you find one nail it might be more so you still want to look
all around to see if there's any other obvious oil leaks get your bright little
flashlight all around and I don't see any
I think place else that's getting on anything the rest is pretty bone-dry
now the lady who owns this car is a new customer she had taken it to one of
these chain discount auto repair shops some young kid was working on it when
she got it back it still smelled exactly the same she knew something was up that
they didn't do a very good job fixing up they said they put a valve cover gasket
in well we're gonna take it apart see if they actually did or if they totally
ripped her off or probably even worse they put the gasket on crooked or
something and it was leaking even worse so let's take it apart it's a relatively
easy job and I just got a few my tools and spikes the case I have to keep
running back and forth basically just need two sockets a ratchet and a little
extension and the first thing we're gonna do with the 10 millimeter socket
is take off the stupid beauty cover just in the way really doesn't serve any
other than making it more annoying to repair take the two bolts off get out of
the way then we're gonna remove the ignition coils cuz they're in the way
it's another 10 millimeter it's four of them one two three or we can take them
all out easily I put the screws up here so I don't lose
them and if you're the forgetful sorry take a picture of it with your phone
then you'll know what your gods wearing you won't screw up putting it back
together and we'll just move them out of the way put them over
here and how they're all in the way then we gotta take these stupid hoses off
just twist this off comes a PCV hose and there's another hose here on this urn we
squeeze it a clamp this one's a little stock so we'll probably with a
screwdriver that's easy way to get them off now
that's out of the way and we just have to move all the bolts that hold into
place and handy enough they're all ten millimeters too well just loosen them
one at a time there's a whole bunch of them they're all over the place
don't forget the ones in the middle and the ones in the back can't even see back
there so get the old flashlight out so we don't miss any of them now they're
all loose and we'll take them off can remove them one at a time
I'll put them in the front here so I remember where I put them want you
loosen them they're really to get off my hand just look close make sure we're all
gone alright nothing the halls now know we'll pull it off cock we pull it comes
off they put a new gasket its supple silicone but they twisted it and had it
crooked so it was leaking down now we're not gonna make that mistake so I use
this 3m weatherstrip glue when I get the new gasket I'm gonna put all glue on the
inside if you notice when I pulled this off it just fell out not being glued in
when he put it down it pinched sideways and then leak you glue certain spots
push it in and let it dry for about a half an hour then it won't slip and
pinch like it did with them yeah what we're waiting for the gasket to come
they're delivering it I'm gonna wipe the edge off to get all the oil off it fell
through when it was pinched all the way around get it nice and clean while we're
waitin we'll see this thing at seventy two thousand three
forty a mile which for Toyota rav4 is nothing even though it's 12 years old
barely broken in and when we look at the top of the inside of the engine
it's an immaculate shape cams are all clean there's no sludge buildup or
anything everything's nice and shiny this cars been taken care of in a timing
chain tight as can be which is a good thing it was a much better design when
they went to timing chains originally a time he bounced it a rubber would break
and they were pain in the butt to change these up chains change they already take
care of it they can last basically forever since the chains inside the
engine the covers off so we see inside its bathed in oil the whole time so it
stays lubricated and it can last indefinitely oh we have the gasket what
will deal with fog little bits of this weather trim sealer in little parts
every once in a while little hair a little middle little layer then a couple
dots in the middle there and a little there with that on tight so it doesn't
leak dry out then you just get the whole gasket assembly check out which way it
goes goes this way and we'll start putting it on and realize this goes in
the middle so push that in a little then you just feed the whole thing around
dress it in so it snaps you want it in tight that's nice and tight and make
sure it's all in its groove the whole way around the previous person didn't do
it this fell off when I picked it up cuz it was just in loose when he put it on
and twisted this way it can't twist you make sure it's nice and solid in with
the 3m weather stripping and the middle too and then let it dry about an hour
okay now it's dry you can see and hang it upside down it's not gonna fall off
and mess up like the previous guys worth did then we simply place it back in
place line up the spots get all the wires out of the way so a little wire
stuck over here then we'll start with the big bolts in the middle because you
want to tighten it from the middle out we want to do all the middle one so put
this one here and there's one in the back and we tighten from the more
out we'll do the back metal one get it finger tight in the front middle one
finger tight then the inside so we get them finger tight then we do all the
other boats working our way out don't want you Snug them all up from the
inside out you then get them talking with a ratchet from the inside out so
we'll start on the back you'll get it tight the touches then a little snug the
same thing here with it so it's snug then we'll do the inside one here the
other inside one then we do the outside ones and the other outside one the top
one here and then the top one on the other side and on the last two now we
know they're nice and tight and we know they didn't bend and twist and leak and
like before cuz we had glued parts in so it didn't fall down and overlap we find
the holes it's over here somewhere there it is
put that back on squeeze that clamp on it goes yeah we'll go over to the other
side through the PCV hose ways to coil the ignition coils go back on it get
them out of the hole they fell into that one go there and goes here and that one
goes there and we touch the four 10 millimeter bolts back in you got a
wiggle or line them up nobody else tighten them all up then we got the
ratchet out and finish them off the next thing we're gonna check the oil cap to the old one
the gaskets pretty much flushed it's worn out here's a new one with a new
gasket you can see this gaskets gonna seal better than this one so we're gonna
change the cap to know people often don't think about the camp and that dumb
gasket can wear out so it's on their neck get it nice and snug and of course
you don't know how much I was lost so let's check the oil
what's not even on a dipstick so we're gonna have to add some oil so I'll add
some oil put in 1/4 stand as we measure it we can see it's on the bottom
that means it needs a whole quart so in goes in the other quart so check it
again and now it's on the top dot it's full screw the cap back in make sure that
gasket doesn't follow any of course you're gonna start it up check for oil
leaks
voila no more lake all dry so the next time your car starts to smell why not
fix it yourself with a little better work it's an easy job to do in many
cases and here's some bonus questions and answers Jenny says I got a
Volkswagen Passat 2-liter turbo a shop replaced my main computer cuz it wasn't
running now it runs but the transmission doesn't shift right what could possibly
be wrong Volkswagens are endless money pits as
you're finding out yet to buy his expensive new computer for it well
everything on Volkswagen is so computer run and I had that same problem happen
with a customer years ago they had the computer changed at another shop and it
ran ok but it didn't shift right well it turns out that Volkswagen has the
computers they're coded and when they're made they're coded either for a standard
transmission for an automatic transmission when I hooked up my fancy
Volkswagen scan equipment I found out that the ECM that the other shop had put
in had been coded for standard transmission but my customer had an
automatic transmission so go to a batter mechanic I have them check all they
gotta do is plugging in it and they can go through their Volkswagen stuff and
they can see what it's coated for and it could very well be that yours is coated
for a standard transmission and all it has to do is be recoded for an automatic
transmission I've seen it before but that's how Volkswagens are she's you've
changed a stupid part on them you got a recode the computer they're just
absolute monstrosity when it comes to fixing them which is why I tell people
if you have brains don't buy a Volkswagen not any modern ones
