Carrera 3.2 rattles when warm

[tonygray]

Hi guys, new to this forum and I'm after a little help regarding a tappy kind of rattling noise coming from the engine.

I have a Carrera 3.2 Targa(65000 miles) and have owned it for nearly a year now. Apart from a few starting problems in the beginning due to a dodgy DME relay and engine earth strap it has run well and started fine. Within a the first 6 weeks of owning it I had the oil lines changed along with a general overall service.

Over the last few months I have noticed that the engine, when warm, has seemed noisier. This is most noticeable when driving in an indoor carpark or next to walls as the noise bounces straight back at me. The noise characteristics are:

- hardly noticeable when warn if at all

- more frequent as revs rise

- it is a sort of tapping/rattling noise

This is the first Porsche I have owned so I don't really have anything to gauge the noise against, only what it sounds like when it is warm which is fine. I recently put the car into a reputable independent Porsche garage to get the tappets adjusted. Upon picking the car up I was told that the tappets did need adjusting so figured that was the noise that I had heard. It was started and it sounded fine but in hindsight what I should have done is take it down the road for a few miles to get it nice and warm and then listen to it. After driving it for the last six weeks I am sure that the same noise is still there and it is not my mind playing tricks on me, paranoia and all that!!

One of my biggest concerns now is that I have read about the valve guides wearing at around 60K on the 3.2 motors so if anyone could shed some light on that that would be great. Would worn valve guides get noisier when warm?

Any help is much appreciated.

Cheers

Tony,

Some mechanics have been succesful in locating "mysterious" engine noises by the use of a stethoscope.

Ask your mechanic.

Good luck,

Gerry

Does it have a light weight flywheel? If so the rattling is normal

[wvicary]

I'm sorry but is it louder with cold or hot engine? You switch around hot or cold in your post. What year is the vehicle? If it has oil feed chain tensioner they could be the fault. What weight of engine oil?

[magcuda]

I am guessing 3.2 is a 84-89 911. the 87 and 88 had valve guide problems.

if your mileage is actual then that is in about the right range.

also could be the hydraulic chain tensioners

if you give year and model when posting it helps with answers
