intake may be cracked as well

[allanbrogdon]

You are a good troubleshooter! My father had a shop in the 70s. Huge shelf full of Chilton's

[josiahtomlin]

Love the videos! Could you possibly do a short or video explaining how you got to where you are today and how you acquired all of your knowledge?

[OscarGonzalez-pkbl]

Always dropping knowledge on us . Thank you

Man, that's a true technician. I bow to you, sir

The second part, show casing the scanner being plugged in, that machine will actually just tell you it has a intake leak, and the possible locations, while stating, to change the one gasket, you will need to change the others to fix the primary intake gasket... I love those scanners. My 20 year old scanner isn't as nice as yours, but in a few months, I am getting the Snap-On unit with the Blue-tooth and additional WiFi hot spot module. My buddy brought one a few months ago, and dang is that unit so much more smarter then my old school unit. All the real time or LIVE graphs of any and or all sensors and I/O of any ECM/BCM is just amazing, which also allows access to transmission controls and read/write adjustment for alterations like tire size to transmission shift points/RPM.. just amazing what can be done now days. Not that I mind manually checking a sensor with a DMM in most cases, but, scanners, although kinda expensive, they are so worth it, if this is your occupation and love what you do, and most of all, desire to make your job easier.

I know I will have to get one soon, due to Porsche's ECM nutcasery, not to exclude Audi and their silliness in their ECM's, that are now starting to flood in from the past 5 to 6 years worth of their production models.. but will even be nice on domestic makes too.

I love your videos, masters of their craft are amazing to watch. Keep up the good work!

Good tip, that's a good bleb on that tyre . 👍🇬🇧

I had a 96 Contour that had a check engine light for 2 years and one of the things I did check was the intake gasket and used brake clean around the intake ports and it actually worked. Turns out the gasket was leaking. But that was not the problem. It turns out it was a aftermarket mass air flow sensor that was about two years old. Went to a junkyard found another Contour took it out and made sure it said Ford on it. Then put it in and never had another light again. 2 years of replacing regular maintenance items. I had even cleaned the old one. Never thought it would be a part I had actually replaced at one time.

Okay this is super useful. I have had vehicles that I could not find a vacuum leak on as the engine didn't change much if at all with that method. Definitely using this trick next time!

[samuelsafer]

I have a 2002 and a 2004 LS v8. This is a very common issue. Please save the 06! They are the best of all the LS years!

[luisvalencia]

Dude !!!! You’re a very knowledgeable tech and your tools are off the chain

[SubsonicWave]

I used brake cleaner for finding a vacuume leak once. Ended up setting my engine bay on fire cause it was an egr gasket if I remember correctly. 10/10 recommend this method👌

[vaughngordon]

That trick has been around a while. Before the O2 sensor though, we just turn down the idle and fiddle with the choke. If it would idle only on choke and you spray she floods up.

[Mark_]

Smoke machine is the best at finding small leaks.

[RogueFamilySmithers]

What's more fun is chasing down an invisible air leak on exhaust side that's causing the O2 to peg lean. It turned out to be a very small hair line crack in the weld on the O2 bung. Had to watch O2 and use shop air and spray all over cuz the intake side check good but was getting false air and O2s where all new in a dealership new manifold cat combo on a rav4 I think it was, I do remember that part was a 3 week wait and around the $800 area before the 4 new O2 sensors, one of those split bank inline 4 cylinders

[ktcarroll]

I just did a 06 Explorer 4.0 and it was actually the intake was cracked on the very top I temporarily( maybe permanently) fixed it with JB Weld and it purrs like a kitten

[FoolOfATuque]

So let me preface this story with a disclaimer: I am not a mechanic, I am a mechanical designer and the other guy is allegedly a mechanic. My parents neighbor brought her truck over. Not running well, no pickup and lean codes from the O2. I sprayed down the intake and didn’t notice any RPM changes with brake clean. I told her I didn’t see any RPM changes, but I still thought it was intake gaskets. I didn’t have time to change them for her, because it’s a big job. She says she has a friend who can do it. 6 months later I see her truck is back in the yard. I asked her if the mechanic had done the intake gaskets. She says, “no, he told me I need a new engine.” So I said I have time to look at it again this weekend and to bring it over. So she brings it over and I work half a day to change the intake gaskets. Purred like a kitten after that.

[kennethcrotts]

I had a Ford Ranger that popped back at the store and immediately started to run like crap. I was worried about it cracking the intake but luckily it blew the pcv valve hose off. Found it with starter fluid.

[MechanicalTriage]

That’s all good and shit, until you find the misfiring spark plug wire!!🔥🔥

[lmontecarlo]

Till you have a coil missfire and 💥🔥don't ask me how I know lmfao 🤣
