nothing is sweeter than the chirping of a honda engine when it starts.
That's normal-sounding around here! Change the oil and put it up for sale on Craigslist. $4999 O.B.O No tire kickers I know what I got.
"Her's your problem lady......the engine is in backwards!" lmao
I hardly do static compression testing anymore but I like a lil' old school that served it's purpose until we started doing leak-down tests. I can't wait until you do a leak-down on the #1&2 and see if you get blow-by between them or into the cooling system especially with the overheating symptoms. Now we have relative compression & running compression tests but nothing replaces the sound of air rushing out of a cylinder into the intake, exhaust, adjacent cylinder, cooling system, etc..and no diagnosing waveforms "Old School" :O On the other hand Man I love my Pico...you can turn anything into a science experiment
Honda for Hanna...the journey begins.
Shhhhh! lol
"Runs kinda poopie" I like the technical diagnostic terms you use. Lol. Nice vids. I enjoy watching.
My daughter drove my '89 Volvo 740 6.5 miles ( going by the mileage for the tow home) with the cooling fan and water pump in the trunk of the car. It got hot. After the tow home I put it back together with a new pump and drove it for 9 months before the head gasket gave out.
Thanks for walking us through the diagnosis and sharing your thoughts. Thanks!
Good morning Eric. I hope your having a great week end. Thank you for the tips in this video. I never paid much attention to the color of the metal on a plug so that was one of those "ah ha" moments. I like this little car so I hope you can save it.
OMG CAN'T WAIT FOR PART 2!!! Great series already :) Makes me want to buy a not so good running car and fix it up!
Have a caddy Eldo. w/ the Northstar engine I'll sell you cheap.
Feel free to help me figure out why I'm running lean on bank 1 (LTFT goes beyond +10%) on my Trans Am, I've been ripping my hair out in frustration about it!!
Despite half the compression packing it's suitcases and leaving, it still runs. Silly little things are dammed near bulletproof. When I was sixteen my father bought me a 1981 model. Despite being used to do reverse donuts, roll backs, being severely overheated and being used to have race down to the local beach (ahhhh the smell of smouldering brake pads) it just would not quit. I ended up selling it for $50 just to get it off the lawn when I got something with more power.
This will be a good series.
Cool working on the Honda. I think the head gasket replacement will cure its ailments. Thanks for getting the series on it's way.
9:38 "who guessed number one?" I did dude and it was because of the color of the thread on the plug. In my experience it's usually the 1 that's that color that the cylinder has took the brunt of it. Old video but just thought I would mention it love ya content dude 😁
Loving the series already Eric
Hi!
I always use "Dielectric Tune-up grease" on Spark Plug Boots.It protects electrical connections,ignition parts and wiring from moisture,salt,dirt and corrosion.
Prevents fusing and tearing of spark plug boots and provides high temperature lubrication on rubber,plastic and ceramic.
My grease is made by"Permatex".
Great Video. This is going to be a good series. The "wait for it" video moment makes it's presence known. Now begins the ever long and drawn out coffee drinking - counter top tapping waiting period. I'm betting that no matter what is found it won't be a challenge for you. Oh yeah... My bet was all four leaking. I just didn't think the worse one would come from the middle of the head. In degree from bad to better was #4, #1, #3 with #2 being the least of the bunch. The coil boots tell you a lot but not the whole answer.
I bet the radiator bubbles on #1 & #2, and a smoke test with hand rotation of engine would be great, too.
66k suscribers erick!i remember when i was 1300..keep up the good work..!am learning a lot from you tx..
Old school or not, this seems so much more accurate than guessing based on relative starter motor amperage. Great start!
I was going to guess #1 or #3 the last few engines jobs i had to put pistons and rings in under warranty those were the culprit cylinders... Btw if you ever get a 2013 Malibu with a 2.5 or any vehicle with a 2.5 and a P0411 and the solenoid valve works but there is no exhaust flow out the head, if you pull the exhaust manifold you will see 3 casting plugs, remove the end ones and clean all the carbon out of the ports... theres little slits that go in to the exhaust ports and they fill up with carbon. GM has us replacing heads under warranty, but cars are coming out of warranty, and i recently had to clean one out due to no part availability due to a redesign coming out in the next few months.
very good to know thank you
Not a bad looking car might be worth spending a little on her.
I'm enjoying the series already,can't wait to see more..🔧🔦
This Is Gonna Be A Good Series!!! -Gets Popcorn
Anibal Misael way better cause Eric will show us the process and not worry about fancy editing 😀 that's why his channel is as popular as it is
Great series...the suspense is killing me!
that thing starts up and runs surprisingly well for as much damage as I suspect it has at least that what it sounds like on the camera
I am glad we weren't betting. I guessed the wrong cylinders. Cool series so far though...Keep them coming.
Done a couple of head jobs on these engines. Pretty easy for a head to pull. Been looking for ones with blown heads or over heats for sale to fix up for my mom to drive
Eric you might check the motor mounts. At 2:11 it looks like she's leaving the nest.
Eric I jumped on for the ride gonna be a very interesting video don't want to miss it
Eric o - Check rad plastic for signs of heat damage. They like too crack after overheating. Plastic will turn whitish/grey.
And the plot thickens..... Thanks for the video.
Once the head is off more will be revealed. From what I've seen thus far I'd be tempted to do only the head and head gasket and drive it and watch for over heating. With the right owner that car ought to get another 100K miles down the road. Great series explaining how much time and effort (money) to put into a car like this. How good is good enough considering the circumstances? That's the question. I've dragged many cars home and got them up and running, most of them worked out some were a money pit. Eric knows what he is doing, it's a gamble but the odds are in his favor.
Love these kind of videos, thanks Eric :)
Once it's done that would be a sweet first ride for your assistant Hannah!
Can't wait to see the head off, and the damage. She's in good hands though, no doubt about that.
This engine is in the sad state. Hope you make something good out of it!
he's not getting a low mile engine from Japan...?
: ( he should.
That car is too good to scrap but is a good project car.good to see we are making a start thumbs up eric.
when i get out of worm at 3am i wait a little to see my favorite channel. then go to sleep.
Can't wait the next episode :)
Eric - after all is done - can you show us the difference how good and blown cranking engine sounds like???
All the best
I think the low compression is caused by both a blown cylinder head gasket & either a warped or worse still,a bent cylinder head where it's beyond machining flat !
It’s like being in school this one with a student project car 👍🏻🇬🇧
I hope you keep this series going. Looks like a good one. I enjoy all your videos. Thanks hope you get that hondu running
Eric, I definitely think you should keep this Car and I think if it needs a New engine, get one. JDM Zone has great solid low mile Honda engines from Japan. just a thought. better than going the Junkyard route.
Poor little Honda. I hope you can put it back on the road. Looks like a decent car. Also, leak down test can show compression going out the radiator in the case of a bad head gasket.
I had a 1988 Toyota pickup with a 22R. I had the head gasket replaced three times. The third time, the Toyota-trained mechanism welded and surfaced the head. Apparently a bunch got through that had defective castings. Also, the harmonic balancer wore in the seal area and started spraying oil all over the engine compartment. Cam chain plastic guides broke too... :
Good video The burning question is will it need an engine, or just major cylinder head work as well as a gasket ?
my call was 1 and three were gonna be lowest three being worst of the two but 4 surprised me being relatively good
Hey Eric, put a Chevy engine in it and you'll never have a problem!!! LOL Bloody 3 o'clock appointment dude screwed up all the fun. Can't wait to watch the next vid.
working for Honda for years I must have condemned and rebuilt 100 D17 motors lol. I personally enjoy that body style though..Order an ELD now ! lol
10:03 - i thought for a second Eric was about to go into "Euclid's Axioms and Common Notions " , " Things which are equal to the same thing are equal to each other"
lightningsmokerXx if a=b and b=c then a=c type stuff?
Already waiting for part2..!! :-)
might get away with just resurfacing the head new gasket bottom end sounded pretty good
it seems you like Handooo Eric
great stuff Eric ...
Another great video.😶🌫
Can't help but think that throwing a motor in her be best with your goal in mind. If you've got the time and patience -ya right- I think the bottom end will work out with only sorting the head.
So if close to 175 PSI is good but not great, how high should the compression be on an engine in good condition?
starts and runs better than some of the cars i have driven.
south main auto repair,add commen rail system videos,air bleeding,starting problem issues extra...
So " the little one" has low compression...Ahh bless...It wont be too long before " the little one" is feeling much better and sounding happy. Lets hope that it wont cost a fortune
Love your channel man!!!
When the Vtec kicks in under acceleration the wheels will break loose when you have it fixed. They are so fast.
Right now there are 4 guys thumbs down. Too bad they can do that anonymously, would be fun to mock them.
All of them are in school learning how to tie shoe strings. We expect them to graduate and move on to bootstrap adjustment next winter.
I wish I could come up there and work for you, I miss home, upstate, north chemung to be exact, just outside of lowman N.Y.
I've scooped up half a dozen of these cars over the years. I just buy JDM engine off ebay. $500 and usually good for low mileage swap. Oil pans and a coolant sensor swap over. throttle bodies are not the same either.
Assuming the block is OK. Can this be rebuilt in the car?
put some oil on the pistons and you know if there are some broken piston rings due to the excessive heat.
Very true but I have also found on an badly over heated the rings and pistons can seem fine but 2 months down the line they turn belly up.
Maybe you can get some vendors i.e.; parts,machine shop, etc for advertisement on this project since you are a very popular You Tube channel. Remember the guy with the scraper company.
not sure if someone else pointed this out but isn't it procedure to put a battery charger on "jumpstart" mode so that the battery getting low does not affect the test?
Can you do a compression check on a cold engine. My 91 Honda Civic turns over but will not start it seems to be getting air gas and spark. Wanted to check compression. It does have new timing belt ignition switch and relay. Thanks 👍
That leak down test is going to show air through the radiator cap.
Dont you have to pull the cylinder head to see the damage done?
Isn't it somewhere around 80psi the bare minimum for a cylinder to contribute on a gas engine? The #1 plug looks like it got nice and toasty!
normal compression should be minimum 175 up to 195
Today's engines are pushing 200, old school pre-emission days would be happy with 125 average and start calling for overhaul in the 60s or lower. But usually at 60 you already have a vague idea it's about done for.
I guessed #2, the swollwn coil gave it away, could of overheated the coil with coolant effecting the spark. Thats my theory, correct? i don't know
Does this make sense.... but I like these more DIY jobs that most can do. Don't get me wrong I like all the vids, but the ones that involve the in depth scanning and repairs that are near impossible with out a scanner are for me would just involve the car going to a shop. But hey...atleast I get whats going on and not completely clueless thanks to these videos.
Cars are becoming more and more computerized and high tech, so having the tools is the new game in automotive repair. Luckily a lot of scan tools can be rented at auto part stores for the DIY'ers own use.
So how did the former owner let the car overheat? Bad radiator? Bad hose?
Hey Eric, do you ever use a bore scope? It would make for a great addition to your great videos.
OUCH! That was my ear.....LOL. Looks like you got a pretty good project car in your hands Eric O. Hoping it works out like you want it to. Do you have any big plans for it after you get all the repairs done that's needed?
The cylinders haven't been weak for very long because the plugs are fairly clean and its not belching out blue, its got hot enough to blue a spark plug. That engine must have been pinging and snapping being that hot, surprised it cranks over and runs. When you blue a spark plug you know it got hot, to blue steel your melting aluminum at that heat. Pull the head off see what the cylinders are like. You really can't trust something when it got that hot, excessive heat does hidden damage that you can't see. Don't want to dump a ton of money into a beater car that when running is only worth 1500-2000 dollars.
The blue part is not steel though, it's some kinda cadmium coating of who can really know. The color change is significant, we just can't apply high carbon steel forge rules is all I'm getting at.
new engine time Eric
My friend says to add some Marvel Mystery Oil and spray it with Sea Foam - he works at Pep Boys!
So Is this a side project for you?or are you doing it during shop time,and billing it to the shop hoping to make it back if you sell it?i personally hate working on cars now for fun or after work,i don't want to use tools in my free time unless I'm getting paid for it...
I did!
pull motor put forged pistons heavy forged components in it put it back together an drive till there's nothing left
Grate job, I can't wait for more:)Safe this car:)
Put a k series motor and manual trans. 🤘
I second that motion. K24 NA. than next season Turbo charge it. 3rd year we'll push back the fire wall and drop in a LS7 motor, rear wheel drive it!!!
First civic fwd LS1?
Oh no...not another Fairmont project.
Nah that's a fraud engine, ye olde vtec is good for 200+hp 250-300 hp is enough for any fwd car2.2 out a prelude will do the job with out the weight of the V8
H22 > k series
pull start through the hood or right where the e brake is on toyota pick up.
Rags2Wrenchs hahaha wat
If it's worth rebuilding
i guessed cylinder #2, what did i win?
Hey, I guessed (knew) three out of four upon hearing it crank.
Next time you're in up State N.Y. stop by the shop and collect your, Swift kick in the ass.. Just kidding. Maybe.
Great Video Series Eric O very much Enjoying this series Super entertaining @SouthMainAutoRepairLLC
Wow, the guy melted that one down good! 1 out of 4 survived! Not good odds ...
Can't wait to see inside this one! Definite head gasket ... maybe some barbecued exhaust valves.
Was it Mrs. O's Odyssey? ;)
No wet test?
what's that whistling noise that the engine is making?
Alternator belt slipping, the battery has had a deep discharge and only a quick boost on the charger so after a start up the the alternator is working full field to bring the voltage up.
A severe case of compression regression. What happened to the car?
It was subjected to thermal abuse?
I KNOW that sound... timing's jumped on that D17
or just over rev lead to a bent valve
just put coolant injection system in it.
i'm gonna say it is leaking out the exhaust valves.
