It wouldn’t start because the coils were melted in the block, could of repaired all that and the engine would of ran just fine, it’s a Honda after all.

I have this motor in my car. 400k and going strong. Nice to see the tear down!

For those that don't know the Honda R18 is very similar to the Honda d series engines except it doesn't have performance VTEC on the camshaft the Honda R18 engine or the Honda R Series engines performance VTEC is in the intake manifold past 5,000 RPM a flap in the intake manifold will open up so that it uses a shorter intake runner

Usually the head has slight warp but ive also had the cylinder liners slightly sink/drop/shrink below the deck surface making decking the block necessary

I worked at a Honda dealership for 14 years, and ran the parts dept for 12 of those years. There was a defect in the block casting of early ('06 and I believe some '07) Civic R18s that caused the block to crack on the back side, towards the firewall. This caused a coolant leak, and engine overheating. If you look on the side of the block, you may be able to see the crack. We replaced TONS of these blocks under warranty. Other than those blocks, it is a very reliable engine. It doesn't have the potential for mods like the B or K series engines, but it's perfectly adequate for a daily driver.

thanks for your content, it's great

Thanks for this interesting video

Great video! I spent many years in the trade, but have never tried this while wearing shades. 😁

These run forever if you dont turbo it 😂

Thanks for the video man. I love this motor

Great video. Subscribed

The coolant passages were known to break. Honda has technical bulletins related to the r18. Its a known issue on the earlier models

enjoyed that Im old but new to dismantling engines. Wish you would get into the habit of treating all parts as if they were going back onto the car good habit to get into even when you know something is toasted. Otherwise very enjoyable

I absolutely love the Honda R18 civics over the K20 SIs and to see that camshaft get pulled out of that engine almost made me nut😅😅😅

Hey just wanted to know what bolts you used for the engine stand can’t find long enough bolts

This engine might be okay to run, new rebuild but these suffer with head gasket failures a lot

19426-RNA-A01 is the stamped steel gasket between the heater outlet and the head?, block? When it leaks it give the indication of a blown head gasket resulting in a broken/ split radiator. My gasket imprinted itself in the poor outlet casting. I filled the impression and pits with JB Weld and sanded it on glass. Worked fine after that…..but first a new radiator or 3 and every other coolant part replaced…. It was the last part of the coolant system I checked.

DO YOU NEED TO ASSEMBLE THE MOTOR WITH THE PARTITION PLATE YOU HAVE IN THE BLOCK? I PUT MY OWN TOGETHER WITHOUT THE PLATE AND IT'S BEEN RAISING MY TEMPERATURE

Hi....Can I know the cylinder pressure of Honda R20A?

How many miles did it have on it?

I once bought one of these a few years ago it was a 2007 Honda Civic and it was not overheating at first cuz I bought it in spring but during the summer it kept on creeping up there was a crack in the block and I replaced the engine after I replaced the engine a disassembled the old engine and found that there was remnants of an old dipstick in the oil pan these motherfuckers that sold me this car knew it had overheated did not tell me and also replaced the dipstick so that I wouldn't be able to tell

It won't maybe because crank sensor???😊

Скільки цей мотор проїхав ?

The middle two cylinders are not two and three The middle two cylinders are 3 and 4 the second cylinder is on the far right hand side of the engine where the fuel line enters the fuel rail

I have that car lol they run for ever 🏃‍♀️

11:16 blop 🤣 Why did the owner overheat it? You can see signs of overheating early on and still be able to prevent this. Did the owner do this on purpose?

11:17 that's what she said

The most likely reason it wouldn't start is that excessive heat warped the cylinder head, possibly also the block. Skimming the head would probably have gotten that engine running again. The soot on the pistons is normal, pistons tend not to melt, the gasket usually goes followed by the head warping. This guy seemed to be enthusiastic but the things he said would discourage me from having him fix my car 🤣.

Honda piston rings killing your engine 😊

One of Honda's best engines lol. I've owned all kinds of Hondas and this thing is a hot pile of garbage. About a year after buying my Civic I get a letter from Honda saying that my R18 engine block can crack it anytime! Plus it's a gutless turd.
