Someone should make aftermarket little rails that go over the cams and lightly spray them with oil like the newer toyota stuff is with roller followers and last forever literally 300k+ miles and all the valvetrain looks fine
FR. looking at VQ springs like ??? Brands that'll list pressures want the better part of half a week's pay for 62-80 on the seat with about 180 @ .450" Others won't list pressures i can find but if you trust em they can take .600" Or another will give you 90 on the seat for twice as much as their 80 spring and don't list pressure at .450"
those Ti retainers look good because of the locator sandwiched between the retainer and spring that might be a different story without the locator in place
Watch what you pointed out and the shinny rings at the top of the holes that the bucket go in I see that the bucket is rocking. Is that not part of the noise? I had this in the old day when they used to cut the cams and raise the bucket to compensate.
Maybe I'm seening this wrong, but to me It is normal that there is less or no wear on the cylinder head cam saddle and more on the caps, because the springs are pushing the camshafts upwards all the time, even if it is honed It still can take lot of clearance, you need enough and the right oil to maintain the oil film, because there is constant pressure applied upwards. Taking in account that the camshaft rotates half of the speed of the engine and that the only spikes in pressure are seen more on the exhaust lobes in a micro seconds as it needs to open against the lower leftover pressure from the combustion gases, the cam journals can take a lot of more clearance, just need the right amount and type of oil, oversize journals with oversize camshaft with a good machining work I guess it is possible.
I've been getting stuff pvd, magnetron, and chemically coated for various reasons and I've sent stuff back or thru it in the trash. You can definitely coat oem buckets but you should be expecting some loss if you send used ones always wise to send extra
I have the BC stage 3+ cams (10.4mm lift) in my VVTI GTE head. The machinists never clearanced the head. The cams don’t bind anywhere. Engine has never been ran. Would you recommend pulling the head and getting it clearanced so they don’t get starved of oil?
@@campbeln the s2’s don’t hit either. They are just close enough to become a problem on some castings. That’s why the failures are sporadic and only a few lobes and not all. Castings are not consistent so there is variance. I would just pull the valve covers off. You can email me pics of the buckets and lobes.
Seems like if cam clearance was off the follower wouldn't look perfect after some scotch brite. I wonder what it is about the metalurgy of the stock followers that won't allow it to hold coating
I happy to discuss weight loss, im a ex bodybuilder , im not a business or any other, like ur videos, i will tell you science behind what i learned, experience
Jay from RS Garage pulled a head you guys did off a 2JZ in his latest video and said he would not reuse it. There seemed to be some questionable machining done to it. Are you able to comment or give us some more info?
Around the 6 min mark Jay mad a comment about the tooling and tool path used to clearance the cams. He also mentioned slight burrs after machining. But I didn't hear anything negative per say. I definitely didn't hear him say anything about "poor machining" or not used the head again because of machine work. Jay is super knowledgeable. Dave is as well. You have to be very careful in deciphering or repeating what's said if you take it out of context or give it extra emphasis that wasn't there initially. I'm sure Dave will view the same stuff, and knowing Dave he will make a change in house to prevent it again in the future. I can tell you as a machinist myself that Dave does amazing work. And there was nothing done to the head in Jays video that would cause concern with me personally as far as using it in its current state. Just my opinion
That head as a come back in April. It was here because it was installed and was started up without any lubrication on the cams or buckets. One of the buckets even seized in the hole! Obviously, there was lots of damage there, and the installer errors continued, as we can now see. For the machining part, a mechanic mentions how it is "different" than what they do, but if you don't own a CNC an endmill is a perfect option to get the clearance. And he doesn't know the difference between a square end mill and a ball end mill because he describes a ball end mill in the video, but we wouldn't use a ball in that arena. I think he should stay in his wheelhouse. He doesn't own a single machine and relies on others to machine everything for him. He might know short block assembly or tuning (not sure if he actually does) but I have forgot more than he knows about anything he mentioned about us. I will say I didn't like the small burrs but it's been there for 35 hits or probably the whole 70 hits is it really a problem or is he trying to find something to start controversy. I would think the latter.
@@headgamesI mean, burr’s like that are always a hazard regardless of if they happened to stay there for however long. Something small that can be an improvement going forward. He’s not wrong to mention that. But sure seems like there’s a lot more beef going on here than just his comments in that video if you are going at him like this.
I'd love to see you lick your elbow, jk lol. GSC S1 cams on a 2j here and curious about the life expectancy for a street car application. The wear on the lobes have me concerned shortly after break in. Self built, self lashed. Not your product just to be clear. Thanks for posting great, informative content.
@@headgames GSC5044 Beehive springs and 700hp max for the streets for now. In a couple years I'll push it to 1000hp if I decide to source a transmission and rear end for the car. Thanks for your response!

Looking forward for that "how to have an idea how to read the spring specs"

well yeah because the spring height would no longer be correct

Thanks ✌🏽

At 6:04 is that a crack at 12:00 a clock 🤔❓
no cracks
How were the main bearings and connecting rods?
I happy to discuss weight loss, im a ex bodybuilder , im not a business or any other, like ur videos, i will tell you science behind what i learned, experience
In other words , it was the vent valves? Will they get noisier as the car warms up ?
It was the intake valves
At 3:27 is that a crack or no? Looks squiggly
no cracks!

@@headgames 👍 Appreciate the reply Dave. Great info you dropped on the Street Alpha Podcast.
I know no one else wants to see but a d16z6 sohc honda im wanting to make more power. Currently at 500

how to pick a valve spring lol
Jay should take the video down and you guys make better products together and be friends again. Real sad seeing Jay's video bashing your work
