Another Noise….

Yep. I tightened it. How did you know I have a tendency to 'over-torque'? That's what I get for relying on a torque wrench…beats a stripped bolt I guess!

I made it almost 1,000 blissful miles. Just enough to be left wanting. The speed and sound of all the cumulative mods is certainly intoxicating.

Here's hoping it is minor.

But, for now, she will remain parked - while I make a living! Those houses don't buy themselves!

houses be dammed, get 'er ass up and get in there man!

Just to update…got the engine torn down to the point of RMS replacement. Thought I would find an improperly-torqued bolt.

Took it all apart. The transmission is out and dry with some dust, not bad. ALL the bolts were tight to spec. No exhaust shield rattles. No muffler noises. 02 sensors & header bolts are tight. LWFW was stuck on there like glue too. No slippage in the pressure plate bolts either. Water pump has 8k miles on it.

Was it all for naught?

Things to still check:
* Spark Plugs
* Header Bolt Torques
* RSS Pulley - though I doubt it
* Oil Filter for metal pieces

The starter motor (see pic). The shaft had a little 'play' or 'wiggle room' in it, is that normal?


I implore you...Can ANYONE possibly suggest something else to check & help a Boxster guy out?

Thank you in advance.

Hey Homeboy,
You are just not getting the breaks.
That sound clip was very short (I understand why), but by the time it had fired, and disengaged the starter it was very hard to pin-point the sound.

Was the noise rythmical- in time with the engine revs? Or was it random, like a pinball banging in different directions?

If it had rythm could it be crank related (shells/bearings) or even a piston picking up on a bore.

I ask as I have read that replacing the dual mass flywheel with a LWFW can have detrimental effects on other components if the are not lightened and balanced also?
So whilst everything you have just taken apart and reinstalled in the last 1000 miles might be tight- the issue could now be something deeper inside with something indirectly affects by the mods?
Rather than just something loose from on the new components?

Keep us updated buddy.

you said;' it was definitely in the tranny' when I implored you to listen closely before taking 'er apart. I wonder if you could run the engine without the tranny in? then you'd know which it is. I know from first-hand experience that sounds travel and bounce off things in cars. Does the tranny look like it's been apart and if so , did they forget something?

Hi Woodsman,

Can I run the engine without the tranny on? I need to put the flywheel on for starter to engage…but that is a possibility to try the old Dual mass FW and see IF it still make noise.

The tranny does not look like it has been rebuilt. Of course, I have heard that the LWFW can cause some issues, maybe it rattled the transmission to pieces? It is curious I first heard the noise between shifts and then 'out of gear' and now ALL THE TIME!

Thanks EssexPorsche,
I KNOW you were "Made to care by your Mum" but I appreciate the sentiment and the suggestions just the same. In fact, you should thank your Mum.

In answer to the one question about the noise being rythmical, it is not. It is like a pinball hitting different spots and being thrown around by centrifugal force. It certainly sounded like a loose nut rattling around. Guess that describes me now..although not funny IF you're the nut!
