Metallic tink
 

So I’ve been hearing a metallic tink from the passenger side engine. It’s regular and evenly space. Not loud enough to hear from the cabin but can hear it through the engine idle with hood open and ear near there. Slightly slower than the DI clicks. I used a a stethoscope but couldn’t really pinpoint it out since in couldn’t reach the side of the head well. I can hear it from the oil control valve area and also on the block near that area about the same loudness. Nothing from the driver side that matches the right side or at least nothing that slow and regular. Increases speed with rpm.

What do you guys think?

Is the car stock?

Yes stock motor.

AT or MT?

Does it do it after the car is totally warmed up?

The cams spin at half crank speed so if the noise seems slower yet steady, could be in valve train. Header leak can cause metallic sounds as well.

MT and yes

OK, so it's not that cam thing that the AT uses.

Must not be a heat shield, unless it slow to warm up and to cool off.


:iono:

Yea I’m as stumped as you. Best case scenario is header leak, worst case scenario is valve train damage.

Well, OK.

Lets see, you said:

Like suggested you may check the exhaust and make sure you don't have a leak.

Since you can't hear it from inside the cabin, I would suggest you just ignore it. These engines make all sorts of weird sounds, that a lot of gasoline engines don't.

Back in the day, I would have called a valve lifter out of adjustment. But, since this puppy uses "buckets" tightening up a little valve slack is a pain in the butt. Besides, being a little loose (chattering a bit) is better than being too tight (can't hear it - can cause a burnt valve).

Besides if the engine is really hurting - it will send you a CEL.

That must be some crazy engine swap. How did you get two engines in there?

No swap, an add.

Sorry OP.

Back on topic, is there a running problem?

No problems, pulls the same, no idle issues, no cel. Don’t have a reader that can pull how the engine is running so can’t tell if any is out of spec.

:slap: you had that ah com-en.


:D
