From the sounds of it the 'well used' camshafts decided to finally give up the ghost when the extra load of the double springs caused a small crack to become a large crack.
From the previous post they are Tomei 270's.
How old were they, or was the purchase condition unknown???

Update!
Well,
The damage wasn't that severe, but the two intake valves in the #4 cylinder has to be replaced and luckily I do have extras. The cams were checked for stress wear and guess what, the intake cam was due to break in another spot as well (I think it was around the #1 cylinder). Quote from my machinist "You were doomed the day you installed those camshafts". Not quite what I wanted to hear, but he knows I'm not about B.S. , so I needed the news given to me straight. The head will get repaired for free and I guess Jon and I need to handle our business as well.
We have a NOPI event on the 14-15th of August and I am planning on having this car tuned and ready. I'm in the process of purchasing slicks instead of using my drag radials and running a crap load of boost, so I'm glad this happened now and not later where it would be pretty hard to justify no abuse. It sucks though, so now I'm going to take a trip on Tuesday to pick-up an SHO I purchased off ebay and attenpt to drive some 24 hours from Massachusetts to Miami, Fl, so I will be out of sight Tuesday and some of Wednesday. This should take my mind off some of the drama.

Well,
The trip was too much to be visiting anyone. Nasty traffic in Boston as well as the rain. Ran into more traffic heading to Rhode Island. Exchanged money for car, starting heading back south, 1 hour delay on the Jersey turnpike and made it home 24 hours after exchanging money for title 1914hours.
Off topic, but related, "Jon" slw240, please contact me ASAP. I don't want our business to bleed to the forum, but you're not responding; soooooooooo..........Please contact me with the information I had emailed you.

Nope, I've built 3 CA's with friends and while I've worked on more SR's, I really like the CA.
If you knew what Dee expects from Jon and Ray and how he thinks someone else shoulf take the fall for his bad luck, then you might understand. It's ridiculous.
**** happens to all of us, it's called bad luck. Sometimes it's an oversight due to our own screwups.
Dee trying to put this on anyone but luck or himself just adds that much more edginess to our community.
i've had 3 water pumps on the same engine within 3 years, **** luck, that's all.
He should take it in stride and stop expecting Jon to trade cams back.

Sorry that I don't post whore myself all over NICO. I actually dont post here often precisely because of the abundance of people like you. So f.u.c.k off.
I dont give a s.h.i.t if you dont believe I've built 3 CA's. Bottom line is that I have, and moderators of the forum can attest to it.
And what's with your insecurity over me driving a BMW? Does it make you jealous you prick? I work hard to pay for what I have and it's not the greatest goddamn car anyway.
It's too bad that you can't spot a whiny bullsh.itter, but Dee is a classic, and I've met him in person.
Why don't you have him tell you the story about going 180+ in his Pulsar NX, then the cop pulled him over and let him off cause he was so impressed...
Unfortunately for Dee and the rest of the NICO tall-tale tellers, I am decidely NOT impressed by people who tell ridiculous lies to my face and expect me to think its real, much less 'cool'...
So go on, crawl back under that rock and I'll go crawl back under the rock I call 'FreshAllloy'.
In case you didnt notice, I generally just use my time to make informative and helpful posts here, this being the exception solely due it it's assinine nature and complete unfairness to Ray and Jon.
Cheers,Sean (my real name)

Actually CA cams to break if you don't tighten them down in the right order or at the right rate. Trust me I did it myself on my CA. And Sean has built a few CA's.
The CA can be a real PITA, especially when you start tearing them up and re-building them. Me and Rock (who Sean helped) were some of the original high HP CA guys. I was the first guy in the united states to get CP pistons for a CA. They used my factory ones as their prototypes.
The cam thing can't be anybody's fault but the person who put them in. It's easy enough to break one, I did it myself. But don't blame it on sombody else.

sean and paul, thanks for comming to my aide, but it wasnt really necessary , nor the way i wanted things handled. if anything it kinda looked abit agressive, i still have yet had a chance to email Dee since me and ray spoke the other night, i have had a very very busy shcedule this week ,and i dont work normal hours, i havent really been online, i only caught wind of what was happening here cause a fellow forum member thought i should see this and help keep it from turning into an all out bash fest. i know you guys mean well but i would have liked to at least talk things over with dee before everyone went before me.
we will get this worked out and ill let everyone know how it goes good or, bad.
thanks for the kind words but please come to me first to get more info before coming on here stirring these fellows up.
thanks jon

Quote » new camshaft seals and new vlave cover gaskets and half moons.[/quote]
Dee, Im assuming you are referring to the cam caps when you say 'half moons'. I cant think of anything else on the engine that would be referred to a 'half moon' besides the main caps and bearings which you stated in your original post were the orignal old ones. please correct me if I am wrong.
Anyways, the cam caps and cam journals are align bored from the factory with the cam cap torqued on the head. This makes every cam cap unique and specific to the original head. If you used new (which is impossible unless you bought a new head from nissan just to harvest the cam caps. becasue they are head specific) or junkyard caps they would most likey cause the cam to bind.
Even if this is not the case, cams are easy to break if torqued down improperly or if you used the incorrect valve springs as Paul has stated above.
Edit: I just realized Dee is probably referring to the rubber seals for the end of the cam journals on the CA.

I really am sorry guys!
Surprise!!!!!!!! I am the CA18_htr............To all the ladies and gents of the CA forums and NICO in general, I sincerely apologize for allowing this to go this far, but as some of you may already know, we had some issues with the forums and the mods as well as the bigger ups, could not log on under own screen names. But without further a due I'll address this portion of the post immediately to Sean or freethinker. I don't owe you anything, Sean. First of all, to say you met me in person and didn't talk that crap to me then already let's me know that you are "SOFT". A real man would've spoke his words in my face, but I take it this title doesn't fit you. So all that garbage you took your time write in malice towards me doesn't mean a thing (Only to you). You must really think about me everyday to gather the intestinal fortitude to waltz your happy kiester into the CA forum and try and slander my abilities and knowledge. You were born with hate, but I will make sure you keep it out of this forum and any other one in NICO since we NICO people tell too many lies!
Second, if you have participated in building a CA engine, good for you. I could care less because you've never contributed nothing to "Our" community as you so call it in your post. You are but an apprentice in building engines and a prime example of someone who really needs a life and a friend. So I say to you, this ain't none of your business "sean" and if you wouldn't let your hate interfere with everything that was disclosed you would clearly understand that I have no beef with Ray or with Jon and especially over some cheap @$$ camshafts.
Now to Paul, as much as I respect your accomplishments with the CA, I am dismayed at this comment "But don't blame it on sombody else". I think you guys are too busy reading the thinking-boy's post that you instantaneously assumed that I'm blaming something on someone and in all actuality I did not.
I'm a performance buff and I get a kick out of faulting myself for my own mess-ups; it just makes me better the next time. I'm not perfect and I will never be, but I know what I know through experience and not because I was handing someone a socket or wrench and then claiming I helped build motors (I build them by myself).
Update is no bent valves! Faulty oil seal caused oil to leak past valves and into the chamber resulting in a misfiring cylinder.
As for putting the camshafts in, none of you have no idea that I install those critical components using a chilton's manual. That's right! A chilton's manual. And the sad part is, I knew something was wrong when I put my cam gear and went to set the intake cam gear to its timing mark (It just turn a little too much). But like any kid with some new eye candy, I finished putting everything together because I was eager to see the fruits of my labor and start tuning on this new rebuild. Even the crank turned a bit too easy, but I was insisting that it was a new engine thing and I shouldn't worry too much. Crank up the car and a miss right away. Never giving the camshaft a 2nd thought because in my mind they were good to go and I was just excited about trying something different.
The problems that occurred did not come from user installation. though I've never broken a cam before, I have stripped the bearing cap threads twice in other CAs due to improper tightening sequences. So I know better and don't need to be told otherwise by anyone.
And "rocksco" that is exactly what I meant in reference to the half moons. My initial observation of the motor was pure speculation and I only mentioned Ray's engine smoking because he brought it to my attention at the time and wanted my advice on what he should do. And then all of a sudden, my engine is doing the same thing, with his old camshafts, but with a miss and taking on oil, so I was lost like everyone else. Just like I stated before, I'm not perfect, but at least I was able to disassemble and take it to someone who can help me figure this out. And contrary to what anyone might think, I am VERY well supported, respected and proven in my neck of the woods and don't have anything to prove to anyone but myself. And once proven to myself, I can share my factual findings with my fellow CA18 owners.
If any of you are interested in being a judge, look at the picture on the 1st page with the camshafts installed in the head. Look at the intake cam journal towards the #4 intake cam bearing cap (There's 6 total and #1 is the camshaft seal bearing closest to the camshaft). Look at the 2 lobes that are on each side of the bearing and tell me if you can't spot the irregularity in the position they supposed to be in.
Jon/Ray,
I am so sorry that this got stupid like this as I only posted to get Jon's attention and not Ray's. I have no business with Ray. Jon and I was discussing this via personal email until Jon stopped responding. And I indicated to him that I know how busy he gets and how he disappears for awhile, but this was something that needed to be discussed soon. But when people come into our fourm and create havoc like freethinker/sean did and then turn around a make a comment like this Quote »Unfortunately for Dee and the rest of the NICO tall-tale tellers, I am decidely NOT impressed by people who tell ridiculous lies to my face and expect me to think its real, much less 'cool'...[/quote] we must quickly intercept them, report them and have them banned "Point Blank". I personally will see to it that it doesn't happen anymore because his intent were a little more than just of the discussion-type.
