Another Noise….

Ok- so it was doing in gear and coasting but not rythmical nor rev dependant.
I would suggest the diff, but I assume from the clip the car was stationary... It's rather like the tranny but I'm starting to discount that as well if was still there and stationary.


It takes me back to the crankcase.
Have you checked the cylinder head bolt and the oil scavenger pumps- both throw bolts that can end up in the oil ciculation.

Well to be more precise the cylinder head can, which can then bust the scavenger pumps which can the throw chunks into the lubrication system?

Drop the sump (pan) and have a look?
I'm hoping for a happy ending.

many, many lwfw's have been sold and used by Porsche owners without problems. the owner of Aasco has been interviewed by Excellence mag. and has been in the Porsche business for something like 40 yrs. You can call him and actually talk to the man himself (like I did), unlike most 'vendors', today. He IS the mfg.
I can't see why you'd need the tranny in , to run engine as long as you have the fw and crank sensor in????? Also ,I wonder if there's an easy way to open up the trans.? How about physically rolling it over, carefully, on the lawn (after draining oil) and listening close for something loose ? Stand it up on the bellhousing etc. But then you said the problem got worse and fast so it could be a disintegrating bearing- I too, feel your pain Homeboy- hope it's a simple fix for ya'

Woody,
Apologise if I offended anyone re LWFW, was just relaying what I have read.
It was not based on personal experience so in hindsight perhaps I should not have mentioned it without foundation.

I was just trying to give Homeboy other avenues of investigation given that he was drawing a blank.

I'll stay subscribed to see the outcome but won't post anymore on this as I am no a porsche mechanic.

Good luck guys.

[woodsman]

Understood ESSEX. It's so easy to relay and so difficult to investigate- for all of us.

First, guys thanks for the insight and responses.

I was moving the transmission around today…to get it out of the way and get into the freezer (which is not a Porsche so it still runs). I noticed that the tranny housing made a loud 'ding' noise. A thought said, "Where have I heard that noise?"

I rocked the transmission again and it made a noise, another 'ding'. I then shook it violently - to simulate the action of a LWFW and it sounded like a bunch of marbles in a can!

It is the clutch release lever mechanism hitting up against the housing. Who picked that? Next question, what is supposed to stop the lever from slapping the housing like that? This is a little more than I bargained for with a LWFW. Too many things vibrating cannot be good. Pity! The driving part of the LWFW WAS GOOD!

Now to confirm my suspicions….I need to start the car. You guys sure I can start the car without the transmission attached? It looks so naked!

at one end it should sit on a ball that's covered with a rubber slipper(?) and held in place by a clip ( I think!), at the other, the slave cylinder shaft. In the middle it's clipped to the release bearing and located on the trans. output shaft. And I've never started mine without a tranny in but was just rationalizing...

That's about the best i could describe it too. All parts present and accounted for.

Have to start it to be sure tho…right?

if I was in your shoes , I would

[woodsman]

As I lay my head on the pillow last night, I suddenly remembered that without the tranny in, there's only ONE ENGINE MOUNT!!!!!Something to consider before starting 'er up Homeboy.
Also, I 've found a 'release arm pivot' piece ( looks like it's a NON-pivot piece actually) on Pelican that my car doesn't have- maybe yours doesn't either???

Homeboy/ Woody

Could the problem possibly be the mounts?
Homeboy- you say all expected parts of the release lever are present and correct.

Not having any experience with LWFW myself, could the vibrations (if of course there are any) be too much for 'older mounts' therefore allowing it to move side to side and cause the lever to hit the housing.

Woody, would new mounts (assuming) they are not new hold everything tight and straight which would stop that side to side movement?

I dunno, just a thought.

Hi Woody,

Thanks for thinking of me BUT you are putting in way too much time! Don't take your problems to bed, take your wife instead…IF she is your problem, then you still have a Porsche! My wife is GREAT…so I can't even spell Porsche when "my head hits the pillow". Another story.

My Pcar is a 6 speed not sure IF it has the piece of which you speak. I got a whole kit from Pelican and installed a new release arm with the clutch. Even replaced the little rubber thingy and spring.

Essex,

All my mounts are new. Transmission and motor mounts have been replaced in the last 15k miles or so. Since you may not be familiar with the LWFW…YES the DO vibrate quite a bit. "gear lash" is technically what it is referred to as. That is why you need a dual mass - although it is double the weight! That is also why some older members do not recommend them.

Saw others do it without problems and thought I could too. Ah well, I will take it on the chin and put the old one back in!

Anyone feeling lucky and wants an Aasco LWFW for around $500 - let me know! It has around 1,000 miles on it. I will even include a clutch and pressure plate with same mileage. It's like getting a clutch and pressure plate FREE or only paying a couple hundred for a LWFW. The Aasco is re-buildable too, you can replace the friction material.

Thanks for all the efforts. i will try to eek out some time to turn a wrench this weekend.

No fun to write and not drive!

[woodsman]

Hey Homeboy maybe you should hold onto that LWFW and clutch combo until it's PROVEN that they're the problem.
My car is a 6-speed too. I found the part on Pelican and have ordered one from Porsche for my car.

[Homeboy981]

Not the flywheel. Eliminated the transmission.

Started car without tranny and it is still making that hideous noise AND I could hear it OVER the open headers!

Going to pull the plugs, check the Water Pump by removing the belt and starting….

Would faulty chain tensioners make that noise?

Any other suggestions?

[woodsman]

Is it possible to have someone with the right lever(!) to turn over the engine by hand while you listened??? Check compression. I wonder if you installed the exhaust after removing the serpentine belt and then used a stethoscope to pinpoint the area? Before doing that, check the oil filter, including cutting it apart. Remove IMSB and inspect. Seek pro-Porsche tech and pay 'em what he's worth.

Any update??
