Rain H8r Valve Cover Modification Master Thread: www.s2ki.com/forums/s2000-rac... - ยานยนต์และพาหนะ
Good Video. This also completely eliminated oil consumption & smokescreening on my 2002 AP1. Just to note as well, Rain H8R also offers the option to modify a brand new valve cover from Honda and ship it straight to your door. This is a great option because you get a freshly OEM powdercoated valve cover with zero down time to your car. This is what I did and I highly recommend it!
Thanks for sharing
Ladies and gentlemen the living helms manual we never got! Thank you so much for the info and instructions you provided sir!
You’re welcome!
Thanks!! My ap1 does this sometimes on street driving! Sometimes when I stop at a stop
Light. Btw my ap1 is in a corolla!😂
Always pleased with these videos! Please continue!
Will do!
Man, thank you for the video!
so lucky to find this channel.
Your videos are very straightforward and helpful. Keep them up!
Thanks will do.
Like the trick with the magnet. I’d like to see a little more about drilling the baffle, where and why the holes are in those positions. Thanks
That will be in another video 😉
@@DIYGuysvideo Looking forward to it! Will probably follow your guide to do my own.
Edit: just did a autox yesterday on 255 square Conti ECS 340 TW tires, and blew huge smokescreens on 2/3 runs. Everyone thought I blew my motor. Consumed 1/2 quart of oil in those runs, and had to stop after the third cause I was out of oil to fill it up with (only had a 1/2 quart bottle left). Newly installed catch can was about half full so in a way, I'm relieved I'm not burning oil in some other way.
The forums have said you have to be pulling big Gs on the track to get the smoke screen, but even on street tires at a 50 second autox course it can definitely happen. This is now #1 on my priority list and I'll be recommending it to anyone who does any kind of performance driving, whether that be autox or track.
I plan to do my own, waiting on your video.
Very informative video , always great video when we can learn something 👏🏾🥂
Switching from Mobile 1 to Castrol Edge helped with normal V-tec misting and blow by for me. But that is minor compared to what you are describing with high RPM's and high G turns. Driving like an old man made the problem go away. My red 2001 AP1 will be 20 years old soon. Still looks and runs great!
Awesome! This happened to me at Sebring two weeks ago, now I know what hunt for 😁
Thanks for sharing my link!
Great info. Have not heard of this issue before but then I don't drive mine on track.
Always informative great vid
I dont track the car, but this info is gold! Thank you!
I too was meatball flagged for this issue. I sent my valve cover off the RAIN H8R and he did an amazing job with a very quick turnaround. He also offers options to red wrinkle powder coat your valve cover and get replacement seals and coil pack connectors. Highly recommended. Since I got it back, I have had zero issues with oil consumption or blowby.
Thanks for sharing!
Such an informative video. Thank you
Thanks for this. I've had massive blowby on certain tracks. Ended up getting a closed-loop catch can setup but checking and refilling my oil levels after every session. Very annoying and expensive in the long run. I'll look into this solution!
@DIYGuys did you consider just changing the valve cover to a 04-05 AP2?
I performed the modification on my 08 so I was already running an improved valve cover.
Thanks for the video. Helpful 👍
2:43 that Porsche was absolutely flying!
I was doing 105 when he passed me haha. Pretty sure he broke a record and did a 1:52 www.speedsf.com/blog/2020/3/3/speedsf-challenge-february-22-2020-round-1-thunderhill-raceway
Learned something new today, thanks
New Softop install video let me know I got a car ready :)
Hahahahaha
Love your videos. Thanks.
Got a RainH8r VC on my 2000 AP1. Only one track day at Gingerman Raceway in MI, but no blue smoke or any other issues.
Good info. Thanks!
I saw blue smoke once on my s2k; I just bought a brand new engine to fix the problem and new chrome OEM exhaust tips
Great video and info
Nice screwdriver set, Costco has them for 12 dollars now for the whole kit. They won’t be coming back so that’s why the price drop so much.
Great video!
My solution was throwing a rod due to lack of oil and finding this video explaining why I burned so much oil in the mountains. The car literally took 4 quarts once I realized I didn't have oil but it was too late... engine was knocking and the oil light still wasn't on. Building sleeved bottom end as I type this.
Might just be AP1 problems if you have an AP1. I doubt you would experience this issue on the street, even if you are driving hard.
Fortunately, I never had an issue with my 2004 S2000. When I went with a turbo, I put in a Crawford AOS and also got a RAINH8R setup for my valve cover. Still no smoke screens on track.
I installed Rain H8r's modified AP1 valve cover on my car and also swapped to using the 2JZ-GTE inline PCV valve rather than the AP1 version. I have 0 oil consumption on track and on the street it's perfect. I have noticed MUCH less oil in my intake arm and manifold as well.
How much oil did your engine use before you modded the valve cover? Do you track the car or just normal driving?
I ended up going with the K20 PCV myself. Not sure if it’s doing anything but theoretically it should
@@DIYGuysvideo It's a bit better and a better designed part.
Fantastic channel & thank you for your wonderful videos of tutorials. I have a question please, when should the Timing Chain be changed on the AP1?, my car has 123k miles & there is no record of it being changed in its Service Records.
Thanks! Timing chain is designed to last for the life of the engine so no change.
@@DIYGuysvideo thank you for your quick reply, I had been told it should have been changed at 100k miles, so I was nervous of daily driving the car hard.
Well that is definitely not in the shop manual. The chain will stretch over time but the timing chain tensioner should compensate for that.
Some people use a pcv from TSX. The TSX PCV has an extended straw reaching further into the valve cover - still leaving 1/2" of clearance to the internal casting.
I actually ended up using the K20 PCV which has a similar straw. I’m not sure if it will help alone but it could be interesting to test that.
Valve cover mod video coming up? Personally I’m going to try using the Supra pcv mod and probably this mod on top. Seen the thread a couple years ago but the way he shows how he does it drove me away from trying but from the small clip you showed, made it seem way simpler!
Yessir. I actually ended up using a K20 PCV in addition to the modification but I’m not sure how helpful it was.
@@DIYGuysvideo it is more free flowing?
It’s not really about flow, it just has a long straw so it should be less likely to suck up oil
There's also nothing wrong with doing both solutions, modding the VC and doing an OCC. Another note, there is no major drawback to putting both the pcv valve line and the breather hose to an open OCC setup like the Smuck one in the video. That stops any potential pull from the intake tract and turns the VC into an output only configuration. I don't know if this will cause any sensor or code issues on certain cars, but it's definitely not an issue if you've moved on to other engine management.
That is true. From what I’ve read there is little benefit to running catch cans on a naturally aspirated motor that supports fuel injection. It is much more helpful for direct injection motors. The drawback to running catch cans in an open system is that you will 100% smell it. I know because I drove that car in the video on track 😉
@@DIYGuysvideo
Turbo DI is where it helps the most from cooking the crap on your intake valves. I just like the thought of an air only air intake....
Thanks for the heads up, I'm just starting to prep my s2000 for track. Will you be making a tutorial video on this subject?
Already did 😎 th-cam.com/video/WkPH67U4UC8/w-d-xo.html
Oh I meant, will you be making a in-depth tutorial on the valve cover mod?
I've had similar problems at the same track with my Integra GSR I'm wondering if that is the same problem
I think I may still do the valve cover mod even though I do have the radium duel catch can system for my AP2.
I would if I were you.
BTW,you should check the other side of the dipstick for oil Level
Anyways great video, I thought this was only an ap1 Issue
Haha I cut the video but after I check the other side
@@DIYGuysvideo I guess my car is not having this issue cuz it needs a driver mod first 😂
And why do AP1s still consume quite a bit during street use where no G forces are present ? Any ideas you could share ? My 2002 consumes 1l of oil in 2000km more or less and other AP1 owners tell me they have similar oil consumption. Keep up the vids, very useful 😉
Based on the research that I’ve done the issue lies in the manufacturing process used for the AP1 Honda S2000. The final engine honing process was different for AP1s vs AP2s. AP2s used a deck plate and AP1s didn’t. This basically leads to some warping in the cylinders which allows oil to get past the piston rings during normal driving. This is why AP2s just simply don’t burn oil during normal driving.
@@DIYGuysvideo so there's nothing to do to cure AP1 oil consumption... thanks for the reply
You could technically rebuild the motor and overbore or sleeve the block but it’s not worth the money.
@@DIYGuysvideo I assume crank vents don't help either.
If you didnt remove the baffle completely (one reason why I havent completed the mod yet) how did you clean the shavings from the back side?
Mainly using powerful magnets to collect shavings while drilling and after. Also using a blind hole deburring tool. Followed by thorough flushing... No guarantees but seems to have worked well for a lot of people, we’ll see.
Do you recommend modding the valve cover just for oil consumption even if you don't track the car?
No. If you have oil consumption on the street you have other issues. Most likely just an AP1.
I’m too slow to get blow by!
soon.jpg
Wished you showed the whole process.
Soon
Are there any downsides to modifying the valve cover? Mine is AP1 and definitely half a quart every 20min session.
If you have the valve cover modified professionally then no. If you modify it yourself there is some risk you introduce which I’ll go over in another video.
@@DIYGuysvideo From what I'm seeing the downside could be leaving metal debris in the valve cover which would be messy. Other than that it's beyond my knowledge.
Noob question, how reliable are s2000s as a daily driver, lets say when they get above the 100k miles?
I would say very reliable, especially if you get an AP2 that doesn’t burn oil. Lots of mechanical enhancements with the AP2.
Hi. Are there any negative effects running a closed catch can on supercharged engine?
Like generally or in the context of the issue in explaining?
DIYGuys in general
Not sure to be honest. Don’t have much experience with super chargers but I know catch cans can be recommended for boosted applications.
@@DIYGuysvideo Thanks for the replies.
Do you drive your s2000 to and from the track?
Yessir
Can ap1 use ap2 valve cover?
Yes but it won’t help much at all.
What I don’t get is why is it happening now and not before . I know you’ve been tracking for awhile so how is it showing up now ?
It depends on the track and skill level. I’ve gotten faster recently and also I haven’t been to Thunderhill East in a while. This issue doesn’t seem to happen at all for me at Laguna Seca or Thunderhill West.
DIYGuys I feel like that is a part of the reason why but not all the reason.
@@Udancearoundme He wasn't pulling enough G's in the specific corner before so it wasn't happening. It largely happens in chicanes when the car is pulling hard G's turning right, then hard G left as you can see in the video @0:59. It forces the oil into the valve cover where it wasn't before then gets sucked up by the PCV and into the intake. It could also be from stickier tires allowing him to have more G's in corners as well. It doesn't happen on every track, just more consistently in a R/L chicane
@Cesar i agree with what your saying but I use to roll in a group of s2000s. 1 out of the 4 would smoke. We would follow each other on track and that one car became consistent on smoking. I’ve also chased down other s2000s that smoke while I did not .
None of y’all had catch cans?
i see you already have the rain8 valve cover mod. But (you may disagree) if your going to the last diamond on the oil dip stick. that is too much oil imo
yes i do track all you have to do is click my name
So filling the oil to the maximum suggested by Honda is too much oil?
@@DIYGuysvideo like i said you may disagree etc imo
@@DIYGuysvideo also have you installed a baffle in the oil pan?
@@DIYGuysvideo well i guess the best argument i can bring up is. how much good do you think that last diamond is doing if it's just burning with the fuel. your not burning a half quart at the same turn on a 20-25 min run
That sucks man. Might as well go fully built track car so you don’t experience street car drawbacks.
Great video!
