Ticking....

[02TruBlueGt]

My valves sound like they are ticking after my dyno run yesterday. I use 87 octance and the guy who did the run at isp rev'ed a lil high i think he took it to almost 7k which i wasnt very happy about on a bonestock internally GT any idea this might have caused it and if i should od a valve adjustment now??

 

[BurningRubber]

WTF, 7k!?! It should have cut off at 6250 unless you have a chip or tune. Stock valves float way before 7k...

Valves are non adjustable on these cars though, just hope he didnt mess something up by spinning it that high.

It's not uncommon for some to hit 7000 rpm with stock internals,but with after market cams.I personnally don't do it,but some do/have.But if your stang is stock,and untuned,he should've hit the rev limiter first,which is 6250 rpm.
What year is your stang,and what miliage does it have?
Sometimes with continuous rev'ing,or high rev shifts,and miliage,things ge tired out.

Sounds like you need to stay the hell away from that tuner.

You might be hearing the injectors because they tick too. Or it could be an exhaust leak. Take a stephascope (sp?) and see if the noise is comming from the valve covers. If it is, sometimes lucas engine oil or STP will stop the ticking.

Well he isnt my tuner. Its ISP racing mainly does evo's rx7s sti's Supra's so i was actually the first mustang he has ever dyno'ed so didnt know what he was doing it was a dyno day. Its a 2002 Gt 51k miles idk how high he went but he said he went to around 7k upwards of there. So yea ill take it to a real mustang shop maybe first ill do the stethascope (sp?) to it and check

 

[deftsound]

rev limiter would have kicked in hes full of ****

 

[1low03gt]

Weird!!

 

[04GTMustang]

i guess it could be possible to rev to 7k cause my car revs to 7k if im just reving it in neutral. I dont try to but sometimes the needle will shoot to 7k and then drop but i dunno if its actually hitting 7k rpms or its just my stock tach

 

[02TruBlueGt]

The car still runs fun and has as much power as before the dyno. I think it may just be the injectors or something it sounds fine until i really start to get into it. So imam take it to JPC and see what they say about it.

 

[02TruBlueGt]

ok so i just went outside warmed up the car and did the screwdriver trick to act like a stethoscope. I didnt hear and wierd noises from the heads. The car only makes the ticking when moving not idleing, and it doesnt change loudness depending on my rpms, the car runs fine no problems. I was thinking of maybe uping the octane to 89(mid grade here in md) from 87 (regular) and seeing what that does cause maybe it is the injectors what do you guys think. Also as far as the guy who earlier said run lucas or stp oil what weight and synthetic or non synthetic. I was told by a ford dealer to run 5w20 Synthetic so thats what i did on my oil change, wrong choice?? What oil shoud i run.Im new to fords always been in hondas but always wanted a mustang.

Also i just took my father for a spin and he said its sounds like pinging. How would i go about getting rid of pinging?? Mods are Slp loudmouth, slp catted x pipe , bbk TB and BBk CAI up the octane im using 87 now shoud i go to 89 or 91 whatever mid grade here is

So see if that corrects your problem, go up to the highest you can, then back down. Detination is not good (really). If it goes away with the good stuff, then go from there. With the mileage, you shouldn't have carbon build up, but it's possible. Carbon build up can cause higher compression to occur, causing pinging. Other than timing adjuster or a change in tune, the bolt on mods shouldn't have anything to do with pinging.

 

[02TruBlueGt]

well just so happens ill be filling up today so i guess to mid grade i go to see what happens. Again only makes noise when putting a load on the engine not idling not revving so i know its not m valves tapping.

 

[02TruBlueGt]

i think im also ordering a sct tuner in the next couple weeks and am gonna have jpc dyno tune my car so maybe that will help i am going to the track in like 2 weeks i want this pinging gone lol any other suggestions what it could be?

 

[02TruBlueGt]

Could a banged up fuel filter cause pinging?? My friend was supposed to change mine before we went to the dyno while i wsa changing my oil. But didnt cause it got to cold. What he did tell was while in the process he bent on the end pipes the on on the fuel tank side before being filtered. So i looked and its really bent. Could this clogg the filter and mess up the mixture and screw things up?? I have one should i throw it on, and maybe that will fix things??

Never let that guy work on your car again

Yes, I think a bent fuel line will restrict flow and cause cavitation in the fuel.

 

[02TruBlueGt]

i have a new fuel filter and could just run up to a local shell where i have a few friends working and get them to change it think that could clear up my pinging??

 

[Kilgore Trout]

Its worth a shot Always best to have things like fuel lines in perfect condition, not all f'n bent...

no doubt! the fuel filter was just changed and the gas came out like green not clear like it should be lol sooo dirty so maybe i should go to a different dyno! so it isnt over revved and re dyno maybe higher numbers
