Trance's all motor disaster
 

Hey guy's I remember seeing this happen to 1 other person on here. I think it was Spoon or Spencer, one of those Canadians ;) But anyway I was siting in traffic idling and all of a sudden my idle dropped down and I heard parts falling on the road and then the engine died.
I popped the hood and what did I find?

Son of a bitch, am I missing something? Oh here it is, the end of the Zex/Compcams camshaft broke off!!!
Attachment 37198

Looks like it'll be resting again until I can find the parts to fix it. What the hell causes this? Poor casting? Imporper tourque? I drove it all summer long and was preparing to drive it this winter too until now...

Re: Trance's all motor disaster
 

either the cam just broke or it siezed up from lack of oil pressure :-X

Re: Trance's all motor disaster
 

The problem is all-motor :P

j/k, but I'm sure a bad casting could cause that. Never heard of it happening but anything's possible.

I can't see improper torque causing that. Too loose you might just have the bolt back off and your gear will completely come off the cam. Too tight.... can't think of anything bad that would happen from that other than maybe snapping the bolt when you are tightening or having it be a bitch and a half to take off.

How are your valves?

Re: Trance's all motor disaster
 

how did that itb d series pull

Re: Trance's all motor disaster
 

I don't know I havn't been able to rip into it yet. I'm actually afraid to!!! Hope I didn't do any other damage. Like I said I was just sitting there idling... The cam gear is now messed up too so it looks like I'm going back to stock parts for a little while.
Oh yeah and the ITB's ripped pretty good in the top end on this little SOHC. I swapped back to the standard Honda intake manifold for the winter but there were definately noticable differences. With the ITB's my low end suffered but the midrange and top end was breathing heavy!!!

Re: Trance's all motor disaster
 

I could possibly see over tightening causing that, but damn. :o That just shouldn't happen. :S

Re: Trance's all motor disaster
 

Yeah I thought maybe if I over tightened it it caused it to form stress cracks or something. It's just odd it didn't break before now, I've driven it for a good 5 months.

Re: Trance's all motor disaster
 

that reminds me of the time i was sitting at a light driving jake's old civic when i saw the crank pully roll out from under the car and roll across the street...

Re: Trance's all motor disaster
 

not the first time ive seen a zex cam break on that end, call em and bitch.

Re: Trance's all motor disaster
 

yeah. tell thoes ----------ers you paid like 4500 to have a motor built you had it for a month or so and the cam broke tottaly destroying your motor >:D see what they do about it. sounds like the NE crew is having some bad luck lateley.

Re: Trance's all motor disaster
 

Really? So this is a common problem with those cams? It was the 59300 model.

Re: Trance's all motor disaster
 

N/A is bad luck...

Re: Trance's all motor disaster
 

they are suppose to be tighten to 27lb.ft :P

yea i`d call the and bitch, at least try to get the $ back if anything

Re: Trance's all motor disaster
 

It didn't come directly from Zex I bought it through a distributor on Ebay. Don't know what I should do.

Re: Trance's all motor disaster
 

doesnt matter its their product. call them up.

Re: Trance's all motor disaster
 

I'm thinking either over torqueing it could somehow do it, but more than that maybe the belt being too tight? But even more of a possibility is that the casting was junk.

If it was a Z6 and you need any parts, let me know. I've got a whole Z6 head that I have absolutely no use for.

Re: Trance's all motor disaster
 

Your the man Stealth. I'm going to contact Zex about it but I want to pull the engine appart and find out if there was any other damage suffered (bent valves etc.) I know my cam gear is junk now.

Re: Trance's all motor disaster
 

I'd say you're pretty fortunate that it happened at idle. I doubt anything got fucked up.

Re: Trance's all motor disaster
 

wow, that's really homosexuall. deff. call up zex

Re: Trance's all motor disaster
 

definitely call them up, and don't say "can you do anything for me" say " my cam broke, blah blah, it was installed correctly, blah blah, so how should I go about sending it back to you" try not to give them the option of saying no we cant do anything. and if you have a way of making up proof that you had it professionally installed, then tell them it was.

Re: Trance's all motor disaster
 

Yes, and you can point them to the site www.professionallymadeturbo.com to prove it was professionally installed and you know what you are doing.

Re: Trance's all motor disaster
 

im pretty sure trance actualy is a mechanic

Re: Trance's all motor disaster
 

If this is a common occurance to Zex Cam ( I've Heard of it before too) I would tend to think the threaded hole is no deep enough, and then when torqued down, the bolt bottoms out and causes it to crack.

I've had this on my old motor. Not on the cam, but I used too long of a bolt and it split the aluminum boss right off.

Re: Trance's all motor disaster
 

Damn Steve thats sucks man.

i've heard and seen many different cams break at that exact point, all after market though. thats why i would only rock stockers ;)

Re: Trance's all motor disaster
 

Oh no Steve!! ---- that sucks dude. i hope you get it fixed quik. had to suck pushing it into a parking lot

Re: Trance's all motor disaster
 

contact Joey Copeland

zextech@zex.com

Pull the cam caps and take pics to show no oiling issues.

If you bent valves, it being a off-road product, your fubared,

Re: Trance's all motor disaster
 

just looked on there website, it just says not califorina legal. not for offroad use only. does it say it on the box for the cams or anything?

Re: Trance's all motor disaster
 

well he's not in Ca anyways. I'd call them up and see what they can do. Maybe they can compensate you a new came gear too.

Yay... I'll stay away from zex.

Re: Trance's all motor disaster
 

Thanks alot guy's, and thank you Mista bone for the contact info. I'll get in touch with him. Thankfully I was idling on a hill so I just had to roll back down. But, I towed it home 3 miles with a rope, haha The homemade way!

Re: Trance's all motor disaster
 

Wait, there's other ways to tow a car?

Re: Trance's all motor disaster
 

Theres a few better way's, but I just happened to have a rope and 1 volunteer Subaru to pull me home!!!

Re: Trance's all motor disaster
 

Well guy's I guess I can't go after Zex for it breaking. I ripped the valvetrain appart on the head and everything appeared to be well oiled. But, the middle cam cap and journal was all scored up. The others were fine. So I'm wondering if possibly one of the oil gallery's is blocked preventing any oil getting to the middle cam cap/cam journal. Maybe it seized up and thats what caused the end of the camshaft to break.
Here's some pics.
This is the rocker arm assembly. Where I'm pointing is the scored up areas.

This is the cam Journal. it too is all scored up. Notice the oil gallery plug that sends oil through the rocker assembly. I wonder if somewhere it's plugged up.

Any opinions on what I should do? I'm probably going to put the cam back in and plastiguage everything to see if this head is junk now :-\

Re: Trance's all motor disaster
 

damn
hopefully the head specs out or u got a double damn
funny part is z6 heads cost way less than a zex cam

Re: Trance's all motor disaster
 

if u wanna get rid of ur itbs let me know :)

Re: Trance's all motor disaster
 

It was god trying to tell you single slammers suck.

Re: Trance's all motor disaster
 

fuk man that sucks, i wonder how that could have gotten plugged up like that?
makes me wanna go change my oil again...

Re: Trance's all motor disaster
 

I think the head is fucked, scored aluminium is bad :-\

Re: Trance's all motor disaster
 

I'll trade them for that Type R you have for sale :D

Re: Trance's all motor disaster
 

trance you should have known god hates all motor hondas

Re: Trance's all motor disaster
 

Hard to say wether you can "buff" out the scratches or not, but you may need a new head. Hit me up if you need that Z6 head.
