"it's been running rough for a few years" that's a big ⛳

These CR-Vs often burned valves due to never getting a valve adjustment. The exhaust valves were set a bit too tight from factory. There’s a TSB from Honda on this for the B20 engines.

A reasonably priced scope and a clamp on amp probe, can provide a super quick overview of an engines mechanical health via a relative compression test. As you likely well know…Of course I only mention this with the benefit of hindsight from your video. Fully appreciate you were only doing what you thought prudent. You got to the root cause of the issue quite quickly. Nice work. 🍻

Sorry you did the last things first. Back in the '70's my mentors taught me to first verify a good base engine and then proceed.

That was funny. Filled up the washer fluid first and change the oil on a misfire. Oh well hopefully you broke even.

When I did work experience with a mechanic in 1993 when I was 15 years old I noticed that the mechanics did a compression test before they did the tune up !

Maybe checking the compression before doing all of the other work and parts replacement would have been a good idea? Would a valve job be our of the question? I guess they aren’t being done much these days?

All of the recommendations made in the video are fine for helping prevent valve problems. The number one thing that was not mentioned at all is to check your valve lash and keep them adjusted properly. This is the number one reason valves get burnt. Exhaust valves get tight over time and need to be adjusted to keep them from being held open. Most of the time it is recommended to check and adjust if necessary every 100k miles. No reason you can't do it earlier though. A lot of the time the valve cover gasket will start leaking around the same time depending on how much the vehicle is driven. Excellent time to check them while you are replacing the valve cover gasket.

I'm so sorry. It's so easy to get focused on the task at hand. I've done this kind of thing a dozen times myself.

I have been an auto technician on and off since 1992. Went thru a 3 year apprenticeship starting in 1993 thru a local junior college and the NCDA. It was pounded into our heads that you always do a compression test before attempting a tune up or any kinda driveability problem. Also why change fluids before fixing the rough running problem? Love your channel and your videos, not trying to bash you, just offering some free advice for next time.

I topped off your washer fluid and added air to the tires and now you need an engine 😂😂

Im gonna be honest you shoulda fixed the misfire before you did all that other work, but i gotta thank you for still posting the video is was a great video as usual. Keep up the good work.

The sound alone when cranking the engine over is a red flag with a cylinder down.

It's now a 3 cylinder engine. Slap a Geo Metro badge on it and carry on.

I give you props dude. I work at a dealer and I’m used to using a rack and whenever I do side jobs I work on the ground and the next day I’m sore lol. Can’t imagine how tired your body will be or cramping when you’re older. Good luck.

valve replacement is super easy on that car

To the comments saying he should have done the scope first, that is a diag. Diags cost fees. Customers don't want to pay for diags and so IMO the correct thing to do is offer to diagnose the misfire and do the tune up if they insist. He did an extra $100 test and he did the labor requested by the customer. Most of my customers are going off what a shop told/quoted them anyway so they don't want to pay for the 2nd opinion, just cheaper labor.

Got your oil change done,, by the way your engine is junk. 😂

I think you can put your old blue 2000 CRV’s engine in the car! You dismantled that car a month ago and that engine would be perfect for it!

Your videos inspire me brother! I have been a professional automotive tech for over 10 years. Im currently serving in the army . I get out next year and I plan on starting my auto repair business. I live your videos and the business truck. Was thinking about checking out some auctions out back home and picking one up. Any advice on where I can get one ? Or much much they usually range in price ?

Listening to the customer just cause they say it might need a tune up was for sure the wrong call. If you just ran the compression test in the beginning and followed by the scope work you could’ve saved yourself and the customer money and time. Love the videos tho just my two cents

8:50😆, now thats max performance.

You think that cabin filter is bad, try replacing one on a Buick Verano or the last generation of the Chevy Cruze. You may as well do the heater core while you're at it.

So in this case do you still charge the customer for the tune up, keeping all the new stuff on the car even though the motor is shot? Just curious how you tackle that.

I don’t believe changing the cabin air filter would have straightened out the rough idle.

Honda's need valve adjustments, at least most have solid lifters and need periodic lash adjustment. Usually intake valves loosen up over time, and exhaust valves recess into the head and tighten up. Exhaust valves that hang open for too long get hot and burn up. There is a saying "tappy valves are happy valves", which pertains more specifically to Honda's. Most people neglect this service and burn up their exhaust valves.

Bro I understand the hustle in cold weather. Im in Ohio

Thank you for sharing this video very informative, so question did the customer willingly pay you for the parts and labor to the car . ? If you provide the service you were asked to perform and then discover a dead or broken engine whom do you believe is the responsible player in the end towards monies . Thanks valuable lessons .

when you get your car tuned up every year, do you change the "filters" both in the engine and the glove compartment? is that necessary? if a person wants to save a few $$$$ can a person do it home?

Hi, greetings from San Diego. Why did you do compression test last and not first? Like your videos.

I once had a Suziki Swift 1.3 4cyl burn a valve. The guide was so worn and rocked from side to side. The valve got hot because it wasn't transferring the heat into the head. Couldn't find a head so I just lapped in a new one and drove it til parts got so hard to find so I threw in the towel

when you mentioned dead motor? can you replace "that part" and get the person back on the road? How much do they cost to replace? is worth it? esp if you did the usual tune up?

South Carolina is a rust area? Looks like a save if it's just an intake valve... Timing belt job at the same time the valve is replaced and new gaskets & the owner avoids a car payment on a newer /used vehicle with more plastic and electronics that'll fail sooner than later.

Here's an idea for the customer... If they live close to a vocational technical school with an automotive shop, have them do that work of removing the cylinder head and changing the bad intake valve... Throw in the timing belt tensioners and water pump too... And check the serpentine tensioner while they're under the hood... Free labor and customer pays for the parts. Hands on training on live cars is one of the better ways to learn besides reading a book

You missed the #1 cause of burned valves on Honda/Acura. Valve Lash. That is what likely happened to this engine.

Could an exhaust manifold leak cause a burned valve?

What killed it was lack of valve adjustment these engines need it done every 60,000 miles to be on the safe side

Many old honda require valve adjustments at 100k or inspection, many people don't check, or even know the manual states it. I had mine adjusted because i bought a car used

Maybe you can buy it from them for scrap value and part it out like the other one ?

If car or truck is running rough I get paid to diag to find out what the issues first . I don’t upsell other things until Iam fully confident on the complaint is fixed or will be fixed .

I heard the engine when you put it on ramps and was like nooooo you shouldn't have topped off the windshield washer fluid or air the tires cause that sounded like rod knock and is trashed

Why is the engine dead? Can't you just get a valves replaced and cyclinder head serviced? should be easy on a 4 banger, right?

Runs rough and sounds like a ticking time bomb

Hi mate, where did you get that bore scope from?

Lots of stuff being done with a bad engine in it I would have walked away from the job cause once you put your hands on it you own the problem and if you can't fix it your not going to be looked at in a good way for awhile that's why I tell all my customers new parts have to be bought and you agree to the fact it might not fix it depends on what it is

Always verify the costumers complaint and do some diag instead of assuming it’s a regular tune up

Can you tell me where you got that scope from? I want one.

Don't understand thought processes here , screen wash ,cabin filter etc with a major obvious engine fault if did that where i work minimum verbal warning and retraining. And how do you do a tune up on ECU controlled system. Just saying my opinion.

tune-up is no longer needed on today's cars. So you should of started with finding out what the problem is first.

What causes a car to stall after putting it in drive? I've already checked for vacuum leaks, changed my spark plugs, changed the air filter, changed the pcv valve, cleaned the throttle body, cleaned the MAF, and it still stalls

Just be hearing the engine. Thats no spark plug issue

Valve adjustment probably is needed

Time for B16 Si head or B18. GSR head!

That's why they call it Auto Joke Ernest lol!

When I heard the engine running I suspected it didn't need a tune-up it was something worse

first things first, weehy the motor so rough and than the rest

What scope are you using?

you completely took advantage of this customer. this customer needed an engine diagnosis; not regular maintenance. You wasted their time and money.

thank you for the video and tip!

Earnest , that did not sound even remotely healthy 😂 upsell an engine swap with a small discount

What was the customers reaction?? 😮

Did you still get paid

The fact you waisted the client all that money. When you could of found this out in 5 mins of looking at a scanner

I think the engine is still salvageable. Those engines are common in the junk yard. Just get another cylinder head, get it resurfaced, change the head gasket and it should last another 80k+ miles. I dont see it costing more than a slightly used newer car.

Talk about an 'arse-about-face' job!!!

that voice does not sound like Ernest!

Are ever gonna do real job on a engine

Aren't you supposed to be the professional? Why would you listen to the customer advice? I think you should have verified by at least cranking the motor in flood mode to listen for an issue. It is pretty much my go-to.

🤣

Too bad you were asked to do a tune up, not diagnose a poor running problem

What's wrong with doing a good old fashion valve job? I cannot believe that you junked a motor because of a burnt valve you need to go back to school!

If something is running real rough and you have a misfire on the ECU… please run a compression test FIRST. Or else either you or your customer are paying for shit it doesn’t even need or can use. Never trust your customers lines of “it just needs a tune up”… how do they know? 😂

Bad motor? Pull the head and replace all valves…. 10 hour job? Takes less then 4 hours to pull the head…
