I think my Cayman reached its expiration date
 

Sorry for the shakeyness up front. This started a couple weeks ago driving home from work. Car's been holed up in my garage since, haven't started it. Terrible clacking, increases with RPMs, driver's side. I'm really hoping it's just a collapsed lifter. I'll have to pull the oil filter for an examination to really know. Then comes the decision of servicing it, replacing the engine, or replacing the car. http://forums.pelicanparts.com/suppo...leys/shake.gif

Anyone care to weigh in?

start with the simple stuff first.....
to me I've heard loose spark plugs sound like that....

Post what u find.

Typically, spark plugs being loose/cracked cause a chirp sound, from my experience at least. Some info on that HERE. Definitely sounds like it could quite possibly be related to the engine. You can always have it towed to a local P car shop to confirm. Here are just some similar threads/videos that sound similar to the one you posted.

Thanks for the links Luccia. Unfortunately my noise gets louder and more pronounced as RPMs increase. This tells me something is really slapping around internally. I'm going to see about offloading the car and just walking away. I can't afford a tear-down, rebuild, or engine swap. To be quite honest I've never owned a Porsche that was so fickle. It's been fun but I don't "love" the car.

Additional update - looks like it is not a [catastrophic] IMSB failure. Pulled the oil filter Tuesday night and just found some small pieces of rubber. Here's a view of the filter:

Sorry for your troubles, recommend you call Vision Motorsports in Laguna to start.

I say it's gone

Brando, that is the outside of the filter correct. Mark

Yes Mark, the outside. I checked the inside - same, no metal.

BoxSinIt -> It certainly feels that way. I wish I could give this thing a Viking Funeral about now.

Hmmmm, sounds like rod knock to me.
Yr and mileage? Any recent service done?

Dwain has a nice shiny 4.2L with your name on it if you choose to go there. GT4 performance at 1/4 the cost.

I heard the same sound and the car still runs.. Turned out the crankshaft and a rod was damaged ��

I'll add that my oil filter did have metal shavings..

Cajun -> Year is 2006 and mileage is 136k. Recent service would be: New rear tires, new MAF, oil change ~3k ago, new spark plugs and coils earlier this year, Softronic ECU tune in March. Nothing that would cause this. If I had the money for that 4.2L, I would jump on it for sure. Going through a house purchase and still owing on the car has made it impossible to overhaul this - otherwise I would be looking at a LS7 swap and AZ plates.

BoxSinIt -> Sorry to hear that. Seems these engines are not as bulletproof as we hoped. I am seriously longing the the days of my 1987 Carerra that had none of these problems, my biggest concerns were lifting in a turn and the stereo being too loud for my wife.

I would definitely take it to an experienced shop and exhaust my options before just dumping it. No chunks of metal is a promising sign, a few thousand dollar repair is definitely better than just dumping it with a "bad" engine.

I am thinking the same, Matt. First reply from the wife: "And how much is that going to cost?"

I guess if I got it repaired I could then sell as a complete running car - get more cash for it.

Burning any oil?

Well my problems started with a cracked head, which led to the an oil/coolant mix.. Then it went down from there. But I had a few overheating issues in the past (I admit I shouldn't of kept driving) that I think led to the cracked head.. Other than that the car was rock steady. 14 years of driving it very hard (2002 Boxster S)

I still have it and its driving like a champ (rebuilt engine) 😃

I would pull the pan; check compression and leakdown. do the basics before sending it to a shop. Doesnt sound good but sound is not 100% reliable. I had a 996 in my shop only making a very slight noise. Thought IMS probably. All 6 rod bearings were non-existant.

Bring it tp a pro just to get a diagnosis it can't hurt

Working in the garage yesterday, I am in agreement about getting it inspected. I'll give Hergesheimer's a call Monday. Just impossible to get anything done with a bike and a car in there, no room... It's either gotta go get fixed, or gotta go.

Oil consumption, I was at about a quart over the last 1100 miles. Luckily it also had no more than a poof of smoke when would I start it up (per usual).
