How To Swap Honda K20 K24 K-Series Camshafts

[@speedacademy]

For all of you wondering - This is a stand alone video that we decided to put together showing the process of swapping cams into a K-Series. It's not another cam swap or a part of the other series. We didn't find too many DIY K cam swap videos to reference so here's our take.

This is the best video by far on you tube to replace camshaft on a Honda K24 with the engine on the car. Thank you guys

[@johnh8546]

Only tip I would add is to pullout the spark plugs makes the engine easier to turn over so you don't have to fight compression. You can turn a K24 over with 1/4 inch drive ratchet with the plugs out.

Y’all really taught me valve adjustments thank you

[@wiltfongdc5]

Awesome video. Just did the cams on my RSX and this helped a lot. Only thing I could say is that when you are cleaning the timing tensioner cover be careful with the blade because I accidentally dropped in down the timing cover into the oil pan lol. Got it out and it's running perfectly now. Also as far as the bungee cord goes I'd say 90% of the time the chain will skip on the bottom and there's no point in really trying to be careful from it skipping. Just make sure before you remove the tensioner and you set the motor to TDC you look at the crank mark and cam gear marks so if the chain does skip you can just install the cams with the gear marks lined up and all the slack on the tensioner side

[@mandotorres746]

I feel so much more competent great tutorial by the dead weight guy he has a calm approach he is a good teacher explains in detail all the way in a calm manner very professional GO TEAM DEAD weight!

[@chadwickwicky67]

6 years and still helping us change cams. Much appreciated. I have a couple of questions hopefully someone can answer. 1) I’ve read people mentioning “preloading” the tensioner, is that necessary? 2) I’ve seen it mentioned that VTC gear needs to be in unlocked position before torquing as well as the opposite. I don’t believe where was mentioned here. Am I overthinking it ?

[@stevenblack2548]

This potentially has saved me a headache. My new head bolts have stretched and now I’m having to tear it down again to re torque them. This is a huge help. Obviously I have to do a little bit more work but this is awesome. Risky stuff but just might make it easier. Thank you!!! 🙏

[@caraddictmotorsports]

Great video. Just did a lash adjustment last night for the first time and that tool is nice. I ended up using a 10mm crows foot and a flathead.

[@chadwickwicky67]

not sure if I’m misunderstanding but I believe he did mention that the lobe should face upward didn’t he?

[@caraddictmotorsports]

​@chadwickwicky67 I did miss it. You are correct, he did at 11:05. I'll edit my comment.

[@chadwickwicky67]

I just want to make sure I didn’t miss anything , I’m about to do this 👍 By the way , I’ve seen others break loose or remove the cam gears when it’s in the engine which looks a heck of a lot easier, is there any major reason to remove them this way instead? Out of the vehicle?

[@caraddictmotorsports]

@chadwickwicky67 To break the cam bolt loose, you just have to secure the camshaft so you're not replying on the timing chain to hold the breaking force. You can do it while the cam is still bolted down so it's more stable.

Smart move keeping the chain under tension for the crankshaft sprocket.

[@the_JDM_fanatic]

How does the centreline make a difference .. 108 / 112 degrees? Put cams in my k20 dyno says it made more power but had to hear the vtec x over but also doesn't feel like it really made any power

[@shinski8114]

wow this video taught me how to do alot thanks i cant imagine it could be this easy tho

Thanx for the vid, helped to have this info when installing my cams. Btw is he (Ruiz? I didn’t quite hear his name well) anyway he sounds like he could be from Hawaii and funny people have asked me if I’m from Canada because of “accent” or the way we talk. I guess if he is born and raised Canadian then I see why, we tend to talk similarly 🤙

Don't own a k-series and still watched!

[@bobbydelamar606]

What cams did you install? Can you just swap in a 50 deg vtc and leave cams? I'm going to do this and Type S oil pump on my 1989 CRX K24A2.

[@MURATSEYİTHALİLOGLU]

How many torque wrenches should I buy to disassemble the engine, to remove the cylinder head, to remove the pistons, to remove the crankshaft.

[@Freestoner707]

You did the same exact video back on Nov 28th and you used a fancy K Tuned tensioner cover. I didnt see that this time but I'm positive it's the same video.

[@speedacademy]

It was shot at the same time but instead of making that video 45mins we split it into two. So yes there are some reused shots.

[@thestigsgermancousin4479]

all the things you do just to get more jam :) love it

[@isaacmoore3285]

There's a TSB out for VTC rattle on cold start that uses a very similar process but you're only removing the intake cam. It's a bit of a pain in the ass at first but once you do a couple its smooth as butter.

[@electro7173]

I know it's a long shot but I thought I'd ask, mine has that exact starting rattle/tapping since the my k24 accord engine was rebuilt from bottom to top - except it was quieter and always made noise from engine on to off. And the mechanic told us it should go away with time. One week later and the noise got awful loud and we said heck with that and stopped driving. What is more likely to be happening; the vtc actuator failed completely, or somehow not getting enough oil pressure to engage? I really don't wanna keep getting bad projection from mechanics.

[@thisaznboi88]

Very nice. Would you do a video on changing out the valve stem seals while it is still on the car?

[@speedacademy]

If you watch our Mustang or S2000 Cam Swap video you'll see the procedure.

[@drivingway2fast]

Lol @ someone's kijiji notification going off at 6:45

[@ryanmccurdy1179]

I may be overlooking something... but as long as your timing marks line up why do you have to keep tension on the chain?? Feel it would be easier to do without keeping tension on it when removing/reinstalling cams.

[@Ninjatuuna]

Ryan McCurdy there is another marking for the oil pump chain on the bottom of the motor, keeping the tension on the top chain keeps the gear both chains share from moving.

[@CyberScott86]

Step by step! Love it! Thank you for this!

[@MrDannyd9]

1:59 is this motor going to end up in the junk pile with the other Honda motor? (reference ungodly amount of RTV on oil pan seal)

[@vic62cu]

I was curios to see how other techs do there cam swaps, i see some key points that raise awareness i would use a paint indicator on chain and sprocket to identify tooth alignment also that. Chain tensioner looks bad why didnt hold tension when you removed it. The VTC actuator needs to be unlocked.

[@kudzy11]

I was searching the comments for this. Yes, i thought the VTC had to be in unlocked position when installing it, then locked and torqued?? I'm about to put my new 50° onto stg 4 DC cams and have getting as much info as poss. Other info I've seen says it must be unlocked 🤔

[@vtecbanger3180]

So as maintenance do a chain tensioner? Also I thought cam swaps kill dependability in a k20 unless going with tsx cams? I'm just looking for daily driver advice.

[@Mawology]

Vtec Banger don’t cam it if you plan to daily drive it. Usually gives you a more aggressive. Rougher idle ect. Good cam set on a built motor can add 15-20 whp

[@carlosbuenrostro7191]

Why wasn’t there any assembly lube placed on the cams?

[@georgekolotouros230]

Carlos Buenrostro I can't believe these guys. No lube . Dummmys.

[@robjr323]

Because it's a straight forward swap

[@brookvalliant7813]

Roller cams don't need it. Cover in oil at best. The old non roller cams require the assembly lube for the break in process. No break in for roller cams.

[@chaserevstuning9271]

I would have put some lube on it to prevent a dry first start up. Other then that not needed.

[@beefnotesaplenty]

Carlos. I noticed that too! Literally came to the comments to see who posted about the dry valvetrain! WTH!

[@waseembux7537]

Hi there, based in south Africa, would a k20a4z cam swap into my k24a3 motor be worth looking at ? I have a set with the vtc gears attached, so it's sitting in my garage and just wondering if itl make any power?

[@817on3]

I did a2 stage three skunk 2 cams in my a3, when you go from the a3 two lobe to the a2 three lobe you need to get a full three lobe set of rocker arms, i just got type s rocker arm and cam cap assembly hope this helps, you just want to look at lobes and the style of vtec

[@JD-rl8kr]

Does the cams add much power?

[@Blessedlife808]

Can you just change the camshaft?, you don’t need the tsx ecu? To tune.

[@brettershoalar9001]

11:55 yes Sir, I also like to go a little tighter-because if you locking up the adjusting screw, the valve lash opens up a bit. I've done this job 3 times on my K20 and it luckily behaves the same over and over. Do you guys know anything about a resurface of the adjusting screw? Why am I asking? ->Cuz I had some issues with them on my D16ZC. They tended to flatten up. It took me to read a bunch of valvetrain books and found a line that states: This can probably happen if you're running the engine with an enhanced valve lash. I've done everything by the book, so what's the problem right here?

[@temoari]

Hey mate. I've got honda crv 2013. Now if I take of chain tensioner like you have will work on a single cam aswell??

[@michaelpugsley1618]

did you guys have to degree the camshafts

[@MarkMyWordsXx]

How much more power should this make?

[@302dan4]

[@MR-zi6rv]

Good job guys

[@chongpooka2769]

My dad took out the plugs and used the power steering pump to move the engine around

[@kalebchapman4849]

did you use the same gears and switch out the cams

[@jayaskoo]

"Obviously" he knows what he is doing. Haha looks like a fun job.

[@Motorsportsgeek]

I dont see why worrying about the chain skipping a tooth on the bottom if you have a timing diagram, the crank just has to stay at TDC and you count the number of links from mark to mark on the cam shafts., even if the chain falls down the timing cover, a magnet can easily fish it out.

[@speedacademy]

Because if it skips then you need take apart the bottom to line everything up.

[@hey_neighbor]

How do you know what position to put the camshaft in? Take note of the original one before removing?

[@georgebrandt541]

Stock ecu will work with camshaft upgrade?

[@RealLeskot]

I heared that aftermarket camshafts may cause problems with tensioner, it that incorrect?

[@PeterHernandezPetesbusylife]

Can I swap out the cams in my K24A4 engine with true V-TEC cams? Like the cams in the K24A2 engine? If so then what cams can or should I get?

[@speedacademy]

No, that motor does not have the same VTEC system as the A2 so sadly if you are looking for more power you will have to swap over to an A2 motor as the A4 is very limited.

[@PeterHernandezPetesbusylife]

Speed Academy what about switching out the timing chain tensioner? I’m considering the Skunk2 timing chain tensioner

[@MiguelangelGarciaReza-pp6vh]

Has any difference with tsx cams?

[@jesusbugarin227]

I don't get the purpose of removing the K20 cams. And for what year of motor... Is this meant for the 02-04 K20 motors since the 05/06 are slightly better. And what K24 cams are you using?? Also does this work for a stock motor or is this just for a motor that has some Bolt ons done.

[@morganburt3688]

[@dawn9340]

Tried to go to your shopping page but it isn't open yet, need a cam. I have an '03 EP3 with a bad camshaft (galling), which I hear is not uncommon. I wouldn't mind doing an upgrade on the new cam, but I am still using this as a daily to work. Any suggestions on a Cam? Is a new tune required if a go with a stage 2 cam, as the car has to pass inspection? Let know if you can. Thank you.
