Valves ticking after nitrous install

[Morgasm69you]

hey guys i installed my nirtous setup on sunday and it kicks @$$...problem though...my valves seem to be louder than before i started spraying :mad: ...just changed my oil (i've been changing at 3-4k and always synthetic for about 22k)and no difference, any thoughts? and the ticking increases and decreases with RPM's...although it's LOUDER when i have it in drive and have the brake on at a dead stop than if i let go of the brake or have it in neutral...

make sure you have the oem oil filter i think someone mentioned it had something to do with the ticking/chattering lifter noises...... it might also be an exhaust leak...my gaskets on my exhaust blew out pretty quick with zex...so i had to do some tinkering/welding to get it finally fixed. also if you dont have an air fule ratio guage i recommend it...you could be running on the lean side..i would check the exhaust first though

[swifty]

maybe a screw loose behind the wheel. LOL :eek:

Your mod list states that you have the wet kit. If this is the case I would be doubtful that you are running lean based on the fact that our cars are pig rich to begin with but just in case, how did you determine how much fuel to add durring spray? You're probably running colder plugs. This is fine durring spray but not so much for everyday driving.

Another option is to go with a heavier wieght oil. On top of that make double sure you are not low on oil.

ahhh, it is entirely possible to run lean with a wet kit. you can change the fuel jet size to lower the ammount of extra fuel. and i ran 1* colder plugs all the time when i had my kit in my car. no problems with fuel economy, ect.

morgasm-- are you sure its not coming from the trans? auto correct? if so, do you have a trans cooler (sorry, didnt look)? oem filter....i know ive read all the posts about this, but ive used a fram (or what ever they have at the place i go) for 75000+ miles and NEVER any probs. if it is valves, take off the valve cover and do a bit of investigating. even if your not sure what to look for, you could always just inspect and make sure nothing is loose. good luck man

esopt--dayum bro, blew the exhaust gaskets. wow

You may need to re-shim the lifters. Get a feeler gauge and pull the valve cover off and check the tolerances. There is a good detailed explanation on hmaservice.com

[Morgasm69you]

i use an OEM filter, auto with a trans cooler, to see how much fuel to use during spray, just used what zex calls for...swifty thinks it may be the fuel lines for the zex pulsating as the pump doesand rattling against something in the engine bay...hope i dont have to pull the valve cover...that would suck balls...and i usually run 5w-30 in the winter, but i'm using 10w-30 for the past two oil changes...grrrrrrrrr

[FordFasteRR]

10-30 is the correct oil to use.

I do not suggest switching to a heavier weight oil to try to fix a DIFFERENT PROBLEM. Same thing goes for the suggestion to re-shim the valves > LOL < . Valves don't just start ticking on their own for no good reason...



If your engine is ticking, it might not even be the valves. It is likely that you blew a rod bearing while spraying, I have seen this happen in the past and that would require an experienced mechanic to determine if the noise is really a valve tick, or a bad rod / crank bearing.

Nitrous puts a lot of stress on the engine. It is possible that you damaged the engine. I would not spray it again until you get this sorted out.


Also, I have a few questions:

1. when you hear the noise, is the engine cold? just started?

2. does the noise go away once the engine warms up? (if not, the problem is much bigger than you think).



A few points to ponder, just fyi .. valves open and close at almost 1/4 of the speed of the crankshaft, so a vlave tick frequency should be much lower than the crank speed frequency ...

For instance, to help you diagnose the tick ,

1. start the engine, let it warm up.
2. rev the motor slightly using your finger on the b ack of the throttle body ..

a bad rod will tick much slower than a bad valve...

so, tick-tick-tick-tick-tick = bad valves
and tick ---- tick ---- tick ---- tick --- tick would indicate a bad rod bearing...



also, it is possible that you are just noticing the typical beta2 motor tick... this happens with ALL beta2 motors and is clearly noticeable at idle and other engine speeds - this is no big deal at all...... =)


good luck !

[Morgasm69you]

probably just the regular motor tick because its DEFINITELY not a rod bearing...it goes like the valves would...i've continued to spray and it doesn't get worse so i dont even care, its the same noise when i start the car and when its been running for a hour so i dunno...worse comes to worse and i f something up i'll remove everything and let the dealer deal with it hehehehe...oh and ford, i'm sending out that fuel rail asap i just haven't had time...

- THANKS !

Merry Holidays ! < LOL

I had a loud ticking noise and it turned out to be a bolt that had backed out slightly on one of the rocker arms. How does something like that happen? Magic, I guess.

[Morgasm69you]

A. whats a rocker arm? and B. How bad is that????

[ghrpdx]

A. Rocker arm definition and illustration (http://en.wikipedia.org/wiki/Rocker_arm)

B. It's not bad at all ... just remove the valve cover and tighten the bolt to the correct specifications. I suggest you have a professional do the work if this is the problem based on the fact you don't know what a rocker arm is.

Does your Elantra have rocker arms? Mine does not.

[SilverElantra]

yes...ur car does have rocker arms.

[swifty]

where? My Elantra has tappets.

[ghrpdx]

My bad ... I was referencing to the engine in my '91 Hyundai Excel that exhibited the ticking/tapping noise. Stupid me for not thinking about the Elantra as having a different valve train design ... SOHC vs DOHC.
