I own a 02 Z28 with about 5,500 miles on it. I needed some advice on some things. Any help from anyone is appreciated.

1)Is it common to hear a tick when engine idles? Not a knock, but can hear the tick even with hood closed.

2)Does adding a air lid void any warranty? I put it on and now I am putting the stock stuff back on till the dealer looks at car, then going to put the Lid back on. Is a hassle, so would be nice if it didn't void any warranty.

3)What rwhp should I expect, I only have a magnaflow catback(going in Friday) and a LS1 motorsports lid with K&N. Is a A4 car. I was thinking around 295 or slightly more.

4)the air breather on the newer Ls1's, after putting the air lid on, now it sits in the engine compartment which would be easy for it to suck water(should I put something around it to protect water from getting in it?).

5)Is it common for the Camaro to jump around the road. On the freeway I have to correct the sterring all the time and when grooves in the road I have to be carefull. I checked tire pressure and all was good.

Thats all for now. Any answers would be much appreciated. Thanks!

 

1) Yeah, it's no big deal. Prolly the belts, mine makes a slight tick noise as well.

2) I'm pretty sure an air lid doesn't void anything, not 100% though.

3) Totally no clue unless you dyno it yourself. Some get 305+ rwhp bone stock, some get less, some get 285, you never know until you get it dynod. But 295 would be a good estimate.

4) Buy a K&N breather filter. You'll find it under the intake section on most performance sites... it's about $15 and fits on the top of that little tube.

5) Umm, I'm not sure. I don't have a big problem with bumps and stuff just ripping the wheel away from me...

 

thanks for the response. The K&N is on the air tube, but I live in Washington and with rain alot I was concerned. What does the air breather do?

 

That little air breather is the inlet for the air pump I think (could be wrong ). If you've got a filter on it, and as long as it's not hanging down on the ground where it'll suck up water, you should be fine.

As far as the ticking noise you're complaining about, my car has made those noises since day 1 as well (as well as the piston slap ). To me, the noise sounds like lifter noise, and since this is my first car with roller lifters, I'd say it's the lifters (or it could be partially to do with the roller rockers as well, since again, I've never had a roller lifter / roller rocker combo). I wouldn't worry about it too much.

Also, I don't believe there's a problem with an aftermarket lid, since just about everybody puts one on their new cars, and to void warranty, the dealership would have to prove that an engine problem was created because of the lid (unlikely).

In regards to the handling and the car jerking all over the road?? I'd say it's the road you're on, and not the car. There's a short stretch of highway near my work where there are deep ruts from continuous heavy traffic (car and heavy transport truck), and I find my car will sometimes get pulled hard from these ruts, but I don't think there's anything wrong, because on 98% of the roads I drive, the car goes where I want it to go. Also, since Z28's have wider than average car tires, they will be a little more tendant to follow wide grooves vs. cars with skinny little tires that will follow their own path, and not the ruts on the road a little easier.

Anyway, hope that helps.

 

cool, I have a appointment to check the alignment tomorrow, they do a free one under 6,000 miles. And the roads do suck around here. I was thinking it could be the rockers too. Thanks for the info.

 

 

Very mechanical sound correct? TICKY TICKY TICKY (YES)

Thanks for the info, is appreciated.

 

Well for one my 02 does have that same sound and I actually think that it could be the Injectors !!

As for the whole air filter deal, I have seen something like that before and it seems that the paper filter is better then K&N and other aftermarket filters but it all comes down to when you are actually getting the air when the car is moving is a different story..

It is like trying to dyno cars with Ram Air versus cars without ram air.. If the car is not moving but sitting still on a Dyno, then of course numbers are going to be similar.. This is just my opinion...

As for the car Jumping around, I agree with psychocabbage and others are saying that it is due to the road and not your car.. even my car does it when I hit bad areas on the freeway or even bad areas of town.. When I am on a Nice Flat Surface, I can let go of the wheel @ 80+ and be straight as an arrow.. Keep an eye on your front tires treads and if they are wearing unevenly then you have a problem...

 

even moving, the air filters ability to bring in air will not be changed. The MAIN difference btw the stock paper filter and ANY aftermarket Cotton/GAUSE or FOAM filter is the "FILTRATION" that is, how small a particle can get through. K&N(cotton) and AMSOIL(foam) both flow the same, but they both flow less than paper.. Now a smaller particle of dust or whathave you can get through the paper filter that would possibly be trapped in either of the two aftermarket filters. So, in a sence it can come down to looks, price, performance, and durability.

For me, a newer paper filter every 6 months is fine at about $15-$20 because the power justifys it.

If I were to use and aftermarket unit, I would use the Amsoil one. Why? cause its black and the foam actually looks like it would catch more crap. Plus it uses a cheaper cleaning solution as it isnt "oiled" but washed.

(note: I have excluded the Holley filter as it seems to be similar in design to the K&N. I will be doing track runs soon with everything just to have the track times to substantiate my findings.)

 

The ticking maybe piston slap.....welcome to the club

The lid won't void your warrenty, but if GM can prove that it is the reason for something malfunctioning, they won't fix it.....Just be safe and change it when you go to the dealers.

Expect around 300rwhp with an A4, thats what I got with similar mods, but then again I think my car is a bitch.....

Just zip tie the air breather to one of the wires, thats what I did and everything seems fine......You don't plan on doing any aquatic traveling with your car do you?

Jumping around on the road??? I haven't witnessed anything like that??? Unless you mean when you smash the pedal and the tires are spinning and it kicks around a little, I have witnessed a little of that

 

Have the same problem :

5)Is it common for the Camaro to jump around the road. On the freeway I have to correct the sterring all the time and when grooves in the road I have to be carefull. I checked tire pressure and all was good.

It's the wide tires, don't worry about your car....There's one road nearby my house here in Orlando that I really have to be very (very) careful on with the 275/40/17 tires I put my 245/50/16 tires (incl. the rims of course) back on my car (only the front) and drove on the same road again, just to compare it... the result ? No problem at all with the smaller tires..... could be the tire brand, too...... well, when it's time for me to get new tires I'm going with 245/45/17 in the front....

 

My Camaro jumps around quite a bit. The solid rear axle has a lot to do with it. My Maxima is 100X more stable than my Z. I noticed when you lower the F-body, springs/shocks/relo brackets and panhard it is a whole other car. Much more stable.

 

Thanks for the help all. Dealer said all was fine, so is just the tires doing it, car came with goodyear GSC's and they have a pretty deep groove and pattern. When I have to get new ones I will just go with Firestone SZ50's, had them on another car and were great. I also talked to 2 dealers and they both said as long as the air lid didn't cause the problem, then it's ok, and at the same time the guy is showing me his MAF screen he removed from his car(kinda funny). I love this board, you get responses! Thanks all for your help!
