Ben Connor: This guy's great.

Michael Gutierrez: I've been running my 97zj jeep for almost a year. (5.2 magnum) and have no problems other then dirty coolent o flush it once a month and use straight water :D

Edward Crowder: Scotty, I have a 2001 Sierra 1500 with the 5.3 engine. It is currently flashing the SES light and giving me a P0300 code. After checking the spark plugs I found this one ( https://www.dropbox.com/s/sgg616ms61ayil2/20141115_151522.jpg?dl=0 ) with oil on it and none of the others did. Could this be the result of a head gasket gone bad?

Munky332: assuming this kit doesnt work on a diesel?

Petey Pablo: Mr. Kilmer, would you say a car losing coolant is a bad head gasket? i see water dripping out the exhaust pipe and the water feels cold but i'm not sure if it's actually coolant or not.

SuperZX: Scotty, I had an unfortunate incident yesterday with my 2007 Escalade. It was driving fine and once I parked it, it started blowing off White steam (or smoke?) and some scorching smell along with some fluid, which exploded all over., I check the engine bay and a heater hose (the left one with the Black fitter connector) was broken, After an hour, I started to drive it in the parking lot again, and I got the "Engine Hot Turn A/C Off" message and more smoke came out. I had to tow it to a near shop. I hope I didn't do any damage. My question is, I had no warning messages or reduce engine power while I was driving to my destination. It all happen after I parked. Do you think I could had blown the head gasket? Thanks in advance!!

Sami Hamid: Hey Scotty, have a 95 Civic EX here. After various overheating issues I have replaced nearly everything involving the cooling system (cost me little to nothing in money so not a major loss). New OEM rad cap, upper and lower rad hoses, OEM thermostat (there wasn't one originally in the engine when i first bought it HA) and new overflow bottle. slowing running out of option as to why im overheating. most of the time the needle goes up only in traffic after a while, so i wanna point towards the fan. but the fan turns on when the needle rises up a little (like midway), and then it drops back down to normal. also the overflow bottle gets past the max line alot and the rad is almost bone dry sometimes when i go to check the next day. so i cant believe that its only a fan issue. ive bled the system several times, and for the most part the car doesn't overheat much but after past experiences its a little concerning to see that temp needle go up past normal. 

kris200998: also its rarely just a head gasket my friend open up his engine to change a head gasket turned out the block was cracked, pistons were worn,rods were worn ended up changing the whole engine

chevyfan999: Trying to figure out if I have a blown head gasket keep getting different answers the engine sounds fine and it's not overheating but there's oil around the oil cap and it's losing coolant but guy says I need a new water pump that it's not a gasket one guy says it is Idk it is a old car and took good care of it if this car goes Idk what to do

Tomlin James: or since its a Toyota you should just go head at 100,000 miles and replace them since that is usually when they fail.

Railbox200: how accurate are these test?

Alex Chevez: Scotty please help me I want to know how to calibrate. The valves in my chevy astro 2000 4.3 vortex engine because have some noise at the passenger side the sound is like if two peaces of metal hitting. Each other. Sound it's not. Too loud 

Sean Gomez: Hi I have a 1997 cadillac catera and it blows out alot of smoke out of the exhaust. People tell me it needs head repair but i dont know. the car runs great except when it starts heating up it blows alot of smoke everytime i accelerate. When i dont accelerate its still blows smoke but less than when i accelerate. when its cold theres no smoke. What should i do?

Marco C.: Scotty, so i bought one of these and tested it, let the car run for about 2 minutes, and it turned blue-green (more blue than green), and its on a gasoline car. Does that mean i have a small leak?

Mickey Bauer: Scotty can i use this test on an engine that only cranks but wont start? If not what would be the appropriate test for it? Thank you

David Mootoo: Hi, I have a 1998 Plymouth Neon 2.0L DOHC (thank you for your sympathy) and my diagnostic said "Cylinder 1 misfire" and the car does not smoke in any way at all. I tried doing the steps in your video, but I was unable to change the coils because of the way the system is made up. Also, just like in the video, the 1st spark plug is really bad, but the rest of them are in relatively good condition. Any suggestions on how to proceed? I live in the Caribbean and my specimen is a left hand drive bone-stock configuration originally from Canada (if that helps). Thanks...

Bruno Erick Gomez: Hey I have a Honda civic that I bought all ready with the engine light on til today that they stole the battery of it I got another one used and started the car it ran as it always do til later on the day the engine light started Blinking and it felt like the car was losing power when I was in a red light so could it be the used battery or wats youropinion?

CJ Daoust: Hey Scotty, I have a 1991 Nissan Sentra Xe 5 speed standard. Ever since I bought it I believe my car has only been running on 3 cylinders. My friend's dad said he could hear a ticking from under the 2nd cylinder valve, and also my exhaust makes a puff puff puff noise when I'm at idle in neutral. Is this is blown head gasket or a bad valve or dead cylinder? I have full compression in all cylinders and I believe oil is leaking into the 2nd cylinder valve , not burning the fuel either. Also a strong rich smell of gas too. 

Maleekus: I'm concerned my wifes '02 Jeep Liberty has a blown head gasket but her radiator doesn't have a cap. Do I use this tester on the overflow tank? Thanks much

Amber Mills: What causes coolant to leak out exhaust flange?

crackermoves: Scotty HELP!! I have a 2000 Chevy Astro van 4.6 Vortec and there is a little coolant getting into the oil ( Not much) however there are no signs of a blow head gasket.. It runs perfect and never overheats.. Whats going on and is coolant squeaking in from the intake manifold to the oil perhaps???? Help help!!

Raquel Mayes: Hello Scotty, my radiato on a 2000 Honda accord is broke, I ran the car hot several of times. However, the car turns over, how confident that the head gasket has been blown???

Jackie Lee: You are a hero..!! I have Subaru forester 2000, at the moment the engine is overheating and no hot air come from the fan. thermostat was replaced to new one, but it has still same symptom. In this case, is it obviously the problem of blown head gasket? cheers

ryann2k1: Hi Scotty. The white smoke coming out from my mitsubishi magna (some black oil not thick when touching the muffler tip). The engine oil is fine but some amount of water is gone from my coolant reservoir. The combustion leak test is showing a change from blue to green. I only did the test about 10 mnts as too much smoke coming out and im afraid disturbing my neighbors. The car runs normally, just the white thick white smoke from the muffler. Do you think this is the sign of blown head gasket?

E. M. Torres: where do you buy this kits?

Naseer Syed: Thinking of buying a cheap e39 for $500. Previous owner says engine overheats because if head gasket. Do engines overheat due to blown head gasket?

vano83: This guy looks like Dennis Hopper! 

Kaio Rafael: Hi Scotty, I am not English native speaker and I wonder what the heck you say in the beginning of all your videos: "...... your engines". I do not understand the beginning of the sentence. Thank you. :D

Zach Pascoe: Scotty I've got a question for you. I have oil in my radiator so i assumed a blown head gasket and bought one testers. I performed the test twice and each time was a negative. Is it possible if the leak is small enough this test can miss it or can something else cause oil in the radiator? 

Rick D: If the head gasket is blown will white smoke come out of the exhaust ? And can oil leak out from the head gasket ? My friend says the dealer is going to charge him 1260.00$ But what are the signs of a blown head gasket ! His 2004 Corolla only has 143,000kms

compaq988: Hello, I have a 2005 ford escape 4cylinder 2.3l, the car was been driven with no oil in the engine and suddenly stops, please, do I need to rebild the engine or the head gasket?

pieter vanham: Hey I have a 1999 Honda Civic LX 1.6 liter 200 horse power engine and its making like a buzzing noise near the valve cover. What do you think the problem is. It only happens when the A.C is on while the engine is rotating.

Andy Gulliver: Ford Focus Ghia 02 - temperature gauge permanently off the dial! Not even drove it 2 miles - head gasket? Mechanic suggest that as all the coolant, pipes and engine sounds smooth including oil levels that its the sensor after engine steam cleaned?

nonamename: how to tell: You have a Subaru.

john darmiento: I accidentally spilled a bit of engine oil into my coolant reservoir, maybe an ounce, will this do my engine harm? 

iRhinoPro: You are cool 

Beaniclava: Correct me if I'm wrong but isn't this test less conclusive on diesel engines? If so how else would you tell? 

phunkyphantom619: my fiat bravo 2.0 makes a hissing noise when i accelerate before you get the tsss noise off the turbo, is there a leak in my pipes?

CarsTrucksAndAirplanes: Where did you buy that kit?

Vet: When I graduated High School, all I wanted to do was kick back and relax without having to do any homework. But I realized I have no money to do anything fun. So I went to a San Francisco Vet School to get trained to make money. But seeing your videos, I am gonna be an internet marketer on the side. Let me know if you have any tips. Thanks.
