Rocker Arm Soup..... I miss my CA (sorta)

[Movingviolation240]

How this all happened Raced 2 bikes







I had to throw that last one in there for all my old CA18 buddies..... damn tin can motors.

dah! that sucks! how long she gonna be out of commision?

[Movingviolation240]

Getting a new one tomorrow at 9am as soon as Kenjuku gets into work. My GF is gonna pick it up and drive it over.

Should be to work ontime at noon

Paul

[GTS4-R]

u got RAS? if not, would it have prevented that?

[Movingviolation240]

I have it, but it happens anyhow

Paul

[Hijacker]

it looked like it split where the RAS made contact

[Movingviolation240]

The RAS isn't bent, dinged, or otherwise looking like it even had a workout. There was a little spot where you could tell somthing touched it, but it was hardly noticable (almost could have been put there when I installed it).

But I only broke 1 so maybe that's what saved the rest of my motor from coming appart.

I also found out that they run pretty good on only 3 cylinders, enough to drive like 60 miles at 80+mph anyhow. And it will still make 1 bar in that configuration, but it lags a lot worse.

Paul

[Hijacker]

the rocker was probably just old and weak.

[Onizuka]

did you get stiffer valve springs?

[Movingviolation240]

nope, step 1 cams and just the RAS. Scott at Secret Sercives seemes to think that that's acceptable. I missed a shift so I can't say that he's wrong, just my dumbness that did it.

Paul

[Hijacker]

i dunno. missing a shift wouldn't stress a rocker like that. i think that it was just ready to go

[ImportIntelligence]

Man oh man, we have 2 motors in the shop now that look exactly like yours. Pesky rocker arms. The FSM says to replace these items as well as the rocker arm keepers aka valve shims. Nissan's fired for this design.

[Onizuka]

At least they built the bottom end right

[Hijacker]

thankfully!

[Movingviolation240]

well, when I say 'miss a shift' I mean 8000+rpm 3rd to 2nd at about 100+mph.

Not good for long term use

[Hijacker]

ok. that's different. i was thinking of closer to 6500

[NeedCAforS13]

BWAHAHAHAHAHAHAHAHA! what are rocker arms... come on, really, I've never seen those;)?

I am gonna have to say read the sig, and remember the good old days! BTW, this is excellent for all the silly SR guys (both here and OrlandoForums) that think that RAS are the end all cure for Nissan's bad design. Come back to the dark side Paul! :firedevil

But in reality, this sucks man:(... if you need any nissan oem parts, call my cell saturday, and I'll get you your stuff! I hope its not too expensive to fix it...

BTW, gotta link this to the CA forums for ya:pface

nope, step 1 cams and just the RAS...Paul

How high did you rev the motor? Valve float sucks. I wrecked an L-series valve train a few years ago.

What's the lift on that cam?

Edit: Ouch... 8000+ before the downshift? Bro....

Sean

Too bad nissan forgot to put a manly bottom end in the CA

My rocker arm stoppers sheild me from everything! Including stupid people named sean and all his CA cronies!

[NeedCAforS13]

lol matt... CA cronies attack!!! gotta kick 'em while he's down, otherwise I just don't stand a chance:pface

Sean

[Hijacker]

funny how that works

[Phax]

Before this gets too out of hand, I have to stand up for my motor real quick. Paul downshifted at 8000 RPMs. 9 out of 10 KA-T's won't even spin to 8000RPMs. CA's will do it, but will they be generating the same amount of torque at that point as an SR?

One of sixteen arms broke. That's not bad, for stock valve springs and cams with more lift and duration than stock.

Paul, am I safe in assuming that SS removed the 7800RPM rev limiter? Do you always rev your motor that high? If so, I'm jealous... and can't wait to finish tuning mine.

[NeedCAforS13]

yeah obviously 400+HP SR owns my ~250HP CA... probably even on 3 cylinders... I'm not a huge SR20 or s14 fan, but I'd make an exception and take Paul's car!:boink

Sean

*edit* or your car too Phax... two of my favorite cars on NICO:bearchug

[Onizuka]

One of sixteen arms broke.

one of eight

This is all in jest by the way guys, we all know that all Nissan motors totally kick arse so there is no point in bashing.

[Hijacker]

yay! i can keep my car!

[NeedCAforS13]

what he said ^ I completely respect the SR, its just not for me... every engine has its strong/weak points:)

Sean

[Hijacker]

some engines have more weak points than others. take the CA for example -=ducks!=-

[Nathan]

9 out of 10 KA-T's won't even spin to 8000RPMs

Since were having fun in this thread I'll just have to say that the KA-T's wouldn't NEED to spin to 8000rpms, we've got the displacement to make up for our lack of revs AND we tend to have more low end torque Sorry about your rocker Paul, have a blast putting the new one in

[float_6969]

yea, I've got my RAS for my CA on order....Oh wait...Hehehe. JK Paul, but good luck with it and hopefully you don't have to deal with that again!

[Dori Dori]

RAS is to prevent valve float people. Rockers are still a suck *** design and can/will break from running at high rpms and/or tons of power.
