Rev up your engines, ok today I'm going to talk about a problem
that most people have at some point in time and that's an engine that's leaking motor
oil somewhere, now my customer here said I've been to lots of places and they can't seem
to find where the oil is leaking from, well they weren't very good mechanics to say the
least, now in the old days to find engine oil leaks we used to have to spray degreaser
all over the engine, then clean it off, then dry it and try to find the leak, well that's
old style, today we use ultraviolet leak dye, now this comes pre measured, you push it to
fill the little container here, then remove the engine oil cap and pour that right in
the engine, it's a measured dose, then the trick is to have some patience, you never
know what pressure is making it leak or where, so you want to take it for a good 15 minute
road test including at least a few minutes going 55-60 mph to build up pressure to see
if it's a rear main seal leak, and now comes the real fun, we get our little ultraviolet
light here and jack the car up in the air, because let's face it, oil goes down by gravity
so you want to start at the bottom and work your way up, and all these kits come with
these funky yellow sunglasses, you need the yellow glasses cuz that makes the dye easier
to see, now the first thing we're going to do is just with the eye and a flashlight and
as we can see when we go to the front of the engine, there's oil leaking all over the place,
so let's look at the front of the engine first, now as we look around we can see the oil is
all over here and we look up we can see it's actually coming from the top too, and I saw
the wiring harness on the vvt was all covered in oil and dye, we're going to have to replace
this, and here we go I got a brand new one, it's got the same connector, the same bolt
on hole everything's the same, and if your curious about what it does, what it does is
it takes oil pressure from the engine and depending on what the computer decides you
need, it sends oil through various holes to actuate the vvt or to turn it off when your
just cruising at a certain speed and you don't need the extra boost, and you might ask why
do they leak, well this part all goes inside the engine and there's rubber seals here that
seal the oil pressure, but if you look really closely here, you'll see this is the part
that sticks outside the engine and there's seals inside there and eventually they wear
out and then they leak outside the engine which is what you don't want, so you just
have to replace them, you don't fix them you just buy another one, there's a hole on top
of the head and it just fits in, your going to have to do a little wiggling as you push
and now comes the fun part, this is the bolt that holds it in, but you can't see where
the hole is so basically you got to stick it in the socket and push it and wiggle it
until it fits and then tighten it up, now here's a trick I learned years ago, I took
a leaf off the vine behind me and stick it in the socket and then push the bolt on, this
way the bolt won't fall off while I'm working trying to get it in the hole because honda
designed it like some kind of crazy mad scientist, here goes nothing we got to wiggle it around
until we get it in, then finally after a ton of wiggling we got the bolt to start and I
can tighten it up, then of course since it's all oily under the bottom of the car, spray
all the oily parts with engine degreaser and hose it off, spray all the greasy parts, spray
it all over and let it soak for 5-10 minutes, and of course don't forget to plug the electrical
part of the sensor in, it snaps right in place, then of course hose off all the old oil and
the degreaser to clean it off, you want to do a fill job and use a flashlight so I can
see what I'm doing, then take it for a good road test, so now you know how to find and
fix engine oil leaks on your car, so if you never want to miss another one of my new car
