I just brought my 87 GT home today with the new performance V6. I had my mechanic readjust all the rockers, and I still hear them tick a little louder than stock. Is this normal for a higher lift hydrolic cam? I can hear it get louder as the RPM's pick up. I can also hear it from inside the cab. It does not sound like lifers with no oil, just louder.

I forgot to mention that I have a crane cam.

could it be the injectors ticking?

the difference in cams really shouldnt cause any ticking.

After building the engine in the 88GT, not to mention fixing the exhaust, I now can hear the fuel injectors at work. I don't remember how noisy the pintle injectors were, because I replaced mine with a set of Multec ball-type injectors. The Multec injectors have a distinct click sound. I pin-pointed the noise using a mechanics stethoscope.

Luck!

I always thought that the first sign of exhaust manifold leak sounds like valve tick.

both my fieros had some tick, both had good manifolds, I too found it to be the injectors.. some tick louder than others.

I have a ticking sound between 1500 and 2000 RPM. Just when I'm accelerating at a normal pace. And it happens in every gear. Even in neutral, I think. I'm not sure what it is. It's been doing this ever since I got it about 6 months ago. 4 spd, by the way.

I vote injectors, in my 85 and 87 gt they both tick.

I am thinking more the injectors, since they did sit out of the car for a while. Plus they are the stock ones with 126K on them. I am going to drive over to the shop that built the motor and have them listen.

I have the same thing. The ticking gets louder and faster with the RPMs. I too have 126k on the engine.

Dont forget about the valves...a lot of manuals have a misprint which causes valves to tick, i too have a ticking sound, but im elaving to the valves as it gets louder throughout the rpm's.

WHAT?!?

higher lift/duration cams with NEW rockers will make noise till they "seat" i just spoke with the dyno tuner then it will be about 1/2 as loud with 1500-2k miles on it...

I have a high lift, long duration cam in my 2.8 with stock injectors and about 100 miles on the rebuild. No clicks, ticks, taps or knocks- so far...

My exhaust manifold leak sounds just like ticking. Take a piece of hose or similar and use it as a stethascope around the mainfolds. If there is a leak, it will be really noticable through the hose.

The injectors do make some noise themselves. Also, the engine probably needs to break in still (?).
