injector dynamics noisy?

[speedjunkie]

I installed some ID injectors and now I hear somewhat of a chatter from the turbo side of the engine. I also added a phenolic LIM gasket to space the fuel rails so they don't rest against each other, maybe that's part of it, not sure. Anyway, wondering if any other ID owners had this problem. Thanks!

Intake leak would be my guess.

Here is a video I took earlier for the sound.

EDIT: Yeah I think you're right. I ran the car and felt for air around the LIM where it meets the engine and it's definitely leaking at the bottom on the front side of the engine.

Just to confirm, that is most definitely an air leak. Though, it sounds more like an exhaust leak... Where did you get the gasket from?


And on a side note, the ID injectors should not be making that much noise.

These injectors are mechanically VERY NOISY compared to any others. These BOSCH (ID re branded) injectors are like that in all cars, I have exactly the same set in a Toyota V6 OEM car and they sound like a little Diesel !!!

Mechanical clicking loudly is the norm with these, nothing to see here, please move on. (4 x ID 1000 fitted to my RX7 sound exactly the same as the Bosch injectors in my daily)

Yeah I could feel the air coming out from the bottom front of the LIM, it definitely sounds like an exhaust leak though, not like an air leak. There is some noise that sounds like an exhaust leak but other than the flex pipe on the DP I can't figure out where it's coming from because I have everything super tight/clamped together in the exhaust system. Anyway, maybe that's the noise you're hearing for the exhaust leak.

The gasket is made by GIZZMO and I got it from MomentumGT.com. It seemed pretty sturdy but maybe it isn't really.

Well I'll listen for the injectors themselves after I fix the air leak. Maybe I'll post up another video then.

OK, I got the LIM and all that off. The gasket is not broken, cracked, or damaged in any way! I have NO idea how this thing isn't sealing. I'm thinking about putting high temp RTV on there and reassembling, but I really don't want to have to take this all back apart again. Plus I'm not sure if it would stay sealed anyway even with the RTV.

The LIM has some dimples in it, but none along any edges to where it wouldn't seal. Man I'm confused.

I'm going to check around and see if anyone else is using the Gizzmo LIM gasket.
