The Automotive "Tune Up" Is Dead. Here's What I Do Instead. Sorted Ep.5

[@LegitStreetCars]

What the highest mileage spark plugs you've pulled? From the messages I've received these were the original plugs with 150,000 miles. I mean I have to admit I can't tell any difference in performance with fresh plugs. These newer cars with super high voltage ignition systems are pretty good at jumping a spark, haha. The dual spark plugs probably help a tad.

[@marinmarinov8660]

I got '87 VW passat/santana. The plugs are over 20 years old and over 100k miles. Once I bought an replacement ones(ngk), just in case, but they go bad after less than 2 years and I swap back the old ones (bosch).

[@bayareasolarpower]

In my w211 e350 I found 3 NGK plugs on one cylinder bank and 3 Bosch on the other side. Replaced them with new ngk’s all around and it gave a noticeable improvement in (smoother) acceleration, i think the important thing is that they matched rather than the brand. Keep up the great mercedes content!

[@DENicholsAutoBravado]

I did some original spark plugs at 144k miles this week on a Camry.

[@DENicholsAutoBravado]

Thinking on it longer, I changed some spark plugs on a Mercedes C230/330 (??? can't remember Mercedes models all that well). Original owner. He said he'd never changed his spark plugs before and he had over 230k miles. I had to work a couple spark plugs back and forth to be confident they'd come out, they all needed too much torque to start coming out. I was careful and I saved his cylinder heads. The boss was upset that I diagnosed the misfire cause instead of just replacing spark plugs and then seeing...If I'm paid to diagnose first, that's what I'm going to do. This was the sort of boss who has a crystal ball and when you find what's wrong he always knew it from the beginning. Some people just don't understand the scientific method. Just because the first thing you test isn't bad, doesn't mean you were wrong to test it. Coils are above spark plugs, so I like to check for spark first before pulling a plug. Rule out the easiest first. 2 spark plugs per cylinder is kinda crazy. I like how in the video he said before to not drop anything under the hood. I went quickly to grab a bolt and somehow it hooked a coil with it and it fell into the very tight engine compartment. 1.5 hours later...sigh.

[@jrfish007]

Did my audi at 135k, found the valve cover gasket had been leaking oil into the plug area and into the engine. Wish someone had done the plugs a while ago and found that easy fix...

Thanks Alex! My 2005 CLK55 is benefiting from your knowledge. In fact I went with it specifically, because of your videos. What a nice ride.

My pops was a mechanic for 30 years. He always took his time working on any car never had any comebacks. He said young guys in the shop would Pride themselves working fast but they always had comebacks he said.

[@ptzish]

Another great video. Thanks. A quick tip, speaking of the carbon buildup on the used plugs. When I was taking mine out of them got completely jammed in the head because when I was backing it out the carbon on the plug clogged the threads so badly that it froze the plug in the threads. The plug wouldn't come out and I also couldn't get it back in. I was terrified that I had ruined the aluminum head. I solved the problem by spraying some WD-40 in the hole and letting it seep into the threads. I worked the plug back and forth a bit at a time until it finally worked itself free. The car smoked a bit after I got it all back together but the WD-40 saved my ass, and my wallet.

[@LegitStreetCars]

Great tip! Thanks for sharing and glad you got them out!

Hi Alex. Another big thank you from Ireland. It’s great going back over your older videos on the how to. Torque specs 👍 etc. Everything you need to know 👍. Used this vid to change the plug on my w210 E55 yesterday. Took me over an hour. Love the jokes in the new videos. Thanks again Paul.

[@MrAgustincuenca]

Awesome video as usual!. A quick note to add is that a good thing to check also, specially if your are doing this in your own garage and you care about your car is to check the spark plug gap and gap it to spec just to double check knowing that almost all sparks now are delivered pre-gapped but it is something that won't hurt you doing.

[@jcsuperstars1100]

Mainly just need to check to make sure they haven't been dropped and left with zero gap. The little plastic/cardboard thread protectors help but it can still happen.

[@TheCarTakerGarage]

When it comes to cleaning the MAF sensor...I do reckon the two "sensoring wires" you cleaned..are the Temp sensors in the MAF.The Maf elements are way deeper in the maf sensor.Anyways...the video is very nice :) Greetings from Norway,Stefan :)

[@FireEye-zd4fm]

You can never access the air flow sensor element from the open side of the tube. So you have to take out the sensor in order to clean it.

[@kavras_fs392]

Dude, you are a life saver my MAF sensor was going bad gave me a check engine so i just clean it and check engine went away thank you

"look at how dirty this air filter is" Um... there was dirt there? I must have missed it. Looked like a like-new filter to me. HAHA

You might have missed the main sensing element of the MAF. the bit your sprayed was for air temperature measurement, the main sensor for airflow is near the end of the black housing, accessible through a convoluted path

There is actually quite a few engine items that need to be serviced. MAF cleaning, TB cleaning, Induction cleaning on direct injection, timing belt, timing chains and tensioners (on anything Ford) belts, fluid including brake/power steering/trans. Cop boots or plug wires. Some still have pcv valves.

[@Darksyne]

A good add on to this "tune up" service is to check and replace your cabin filters since you're doing routine service anyway. Periodically changing cabin filters will definitely improve your interior air quality especially if you constantly run the A/C or heat and helps prevent premature Blower motor failure.

[@theil6]

Hi Alex, Just did the air filters, Cleaned Mine they are reusable and pulled the mass airflow and cleaned that as well. I couldn’t do the Pipe due to I need the short Torx extensions. Next time. Thanks for all the Vids.

[@LegitStreetCars]

Awesome!!! Yea just take a look in the pipe and if it's clean just put it right back and you are done. Thanks so much for watching. Alex

[@rockymountboy]

I asked a mechanic what a tune-up includes these days, and he sid the same - change the spark plugs, check the air filter. I asked a mechanic why they still call it a Lube-Oil-Filter if they don't lube the chassis anymore, and he just shrugged his shoulders.

Regarding your question about the NGK/Bosch plugs from the OEM - I had the same dilemma as I wanted OEM spec. From what I reseached, NGK PFR 5 -11 spark plugs were designated for AMG M113 engines and Bosch spark plugs were designated for non-AMG M113 engines. Mercedes-logo spark plugs back in the day were used to be NGK, but then switched to Bosch (not sure if for technical or commercial reasons). Most importantly, AMG M113 engines must have resistor type spark plugs with 1mm electrode gap, which Bosch F 8 DPER is.

[@makeminefreedom]

I have a 2001 GMC Sierra 2500HD with over 160,000 miles with the original spark plugs and wires. I have used AmsOIl since the first oil change and it still runs like new with no oil leaks or smoke out of the tailpipe.

[@DENicholsAutoBravado]

Sanctus Vianney good call. All kinds of people have told me over the years that Denso was original equipment or OE, but at least on 1 car, it ruined my acceleration permanently even though I went back. I wasn't a mechanic yet, but it was very disappointed. I still wonder to this day what was it that it broke? I have all kinds of answers now if you want to know tons about spark plugs, I have a series on the subject.

[@waterzap99]

Neighbor picked up a socket of mine the other day in the street in front of my house. I had dropped it in the engine a day or so before. It was gone, gone, gone. I agree with the Bermuda triangle analogy. I think the heat and combustion process creates some kind of spatial anomaly around the engine. If you drop something, you would think it is right where you dropped it. But no. The reason you cannot find it is because it is in fact not there anymore. Might appear later again though. 500 years from now we are going to fly space ships on this spatial anomaly principle.

[@DENicholsAutoBravado]

Oh waterzap99! Have I got a good one for you! Around 2005 or 6 I was working on my 1999 Chevy Prizm. I dropped a 1/2" to 3/8" adapter. It fell silently. Not a sound. If I hadn't watched it fall, I wouldn't have believed it fell. Not a clink. From sunlight to darkness so fast. I spent a lot of time looking for it and gave up. Fast forward to about 2014. I needed to change my starter. I could find where one bolt head was that held it in, but I was clueless about the other one. There's this deep dark whole on the other side of the intake and also on the other side of the transmission, where I was fumbling around and failing to find the head of this bolt for more than an hour. There's an object which is smooth which feels like it has a hole in it. I thought, could it be a 3/8" driven bolt of some kind. So in goes my extension. I felt it move. I pulled back and whatever it was fell back silently. I tried fishing with my hands, and in this oily hole with all the cushion from dirt and oil in the world was my 1/2" to 3/8" adapter! Excited, and without this extra object in the way I finally found the 14mm bolt head I needed to be on and this starter was coming out!

[@kimdelgado6239]

Hi Alex, great videos! You have inspired me to take on a spark plug change for my 2012 E 350. There is not a lot of info out there for me to reference. I would love to see how you would tackle this job. Please keep the videos coming.

Is it reliable or is the diesel twin turbo V8 known to fail? Much love from Sweden

[@nicke2307]

This is alittle more advanced and involves more expensive equipment but Ive found a throttle body relearn can also help along with a MAF cleaning But you need the dealer scanner

[@springfever2002]

I used to tune up on my cars before when I was in my teens, early twenties, but thought I was screwing up and discouraged me. A mechanic told me that mistakes will happen when working on a car. A part could be bad from the parts store, which makes tuning or repairing your car a nightmare. Anyways, I stopped diying on my cars afterwards, and didn't think anything of it until most recently. My Montero stalled and will not idle. I was going to take it to the mechanic, but I stopped myself. I began reading online, watched some videos, and now I'm digging through the engine compartment looking at air and fuel problems. The MAF seems to be a common issue with Mitsubishi' s, as is the egr.

[@ssk168]

Great video as always. Looking forward to your next video removing front bumper. I will be removing my C32 front bumper so I can install heat exchanger.

[@BlagoP]

The factory plugs are NGKs. If you buy them from the dealer, they will have the Mercedes logo on them and cost an arm and a leg. The Bosch plugs are the cheaper alternative. I did the plugs and wires on my E55 without removing the ignition coils but I am guessing it's much tighter on the C55. Either way, the plugs on my S6 V10 were quicker to change.

[@pd1jdw630]

There are some dealer whom are straight out honest with you. They just tell you the engine has a problem with the timing belt breaking before, oh let’s say 120k miles. And so they recommend you to come in at around 100k miles. But hey. Not every dealer is they same, even though they wear the same badge in front of there shop.

[@JamesAllen300]

They were NGK's out of the factory. The number I have for them is ILFR6A and a gap of 0.8mm. Bosch plugs are FR6MPP332 with a gap of 0.8mm if anyone needs the plug code.

[@69shovlhed89]

1. don't disconnect the coils from the wiring, just swing the whole mess up onto the intake manifold. 2. MB uses ngk and bosch spark plugs interchangeably. 3. be real careful with the airbox screws, they thread into plastic and will strip out. 4. if you do remove the airmass, likely both the seals on the elbow should be replaced. 5. don't fuck with the EGR tube unless you really need to. its easy to fuck it up. 6. lube the airbox to airmass seal before you reinstall the airbox. I've seen more than a few of them damaged from installing it dry. also lube the rubber bumpers the airbox clips to, so the clips slide on and don't bend.

[@nickopedia5669]

With electric fuel pumps and large filters you don't even need to change the fuel filter. That's why they made it so hard to change. Changed mine at 370,000 miles and had no change in rack pressure, because even 370,000 miles of gunk isn't enough to cause an issue. For me a typical "tune-up" involves cleaning the MAF, running injector cleaner, sea-foaming the intake, and blowing out the air filter. Cleaning the maf and air filter probably has the biggest effect. At the same time, don't fall behind on carbon build up because you don't want to do it when you have 1/16" of crud that will flake off in chips and cause wear.

[@ivandzivkov]

I’d still call it a tune-up, maybe less items involved but you are still going over the car & addressing any maintenance it needs & checking for issues... to me that is the definition of a “tune-up...”

[@DENicholsAutoBravado]

Matt's Garage maintenance really enhances how I ride feels in my opinion. Anything that makes it run better makes it feel "more tuned" to me, even though literally modern cars tune themselves. They can only tune as well do as well as the parts they're given, you know? I have a series on spark plugs if you're interested on more in depth concepts I've learned over the years.
