NOISY 997T ON START UP

Recommended Posts

Just had a major service including spark plugs of my 997Turbo at a Porsche dealer.

Since its been serviced on a cold start Ive noticed the engine is really rattly for about 2-3 seconds, then it settle down to normal.

The noise is like a mechanical rattle for a few seconds almost like it is running dry until oil gets there then it quietens to normal.

The car has done 35K, didn't do it prior to its service and the noise is it has to be said not a nice noise.

Is this something anybody has experience of and can help with?

The Porsche centre at the moment are stating they don't know how it could be linked to the service...

Thanks,

What oil were you using prior (brand and viscosity) to your recent service? What did the Porsche center put in??

Is the oil level correct???

Maybe there is something wrong with the oil filter and/or the valve inside the filterhousing, and comes empty at a longer standstill. The filterhousing is mounted upside down on this type of engine.

Not sure what oil was in prior to service as Ive only had it 6 months.

Oil level is bang on max level

Well, the problem with being at "max" is that you don't know if it is overfilled, and if so, by how much. May be something to consider.

Agreed. It shouldn't make that noise. I would take the car to another shop and have the oil level and filter looked at. There are two 'O' rings on a TT's oil filter. If they are not installed properly it can cause a problem...I wouldn't drive it until I had it looked at.. A Turbo engine is about $50k..

I can't stress how important oil level is in this car. I'm currently fronting a $28k engine rebuilt b/c one of the connecting rod bearings failed...most likely due to insufficient lubrication.

HiI have the exact same problem, my car wasn't even due a service, oil level was good, when the noise started, it just appears for 2 seconds on cold start.Anyway so I gave the car a oil+ filter change, using Oem filter and mobil1 0-40 oil,filled to the right level.The rattling noise still comes during start up.Any other ideas what it could be?

Mark, you said you had the spark plugs done at the service. Just wanted to be sure you've looked into making sure those plugs are nice and tight. Loose plugs have been known to cause a rattle.

Just a thought here.....Easy solution. Since you just had it done at a dealer...Bring it back to them and let them figure it out? Also, if anyone has ever tried to change the plugs you will appreciate that you cannot check to see if they "are nice and tight" unless you have about 8 hours to kill and still will only be able to reach about 3 of them...

I would just take it back to the dealer....Good luck to you!

Hi

I have just had my 997.1 tt serviced and after the car was left standing for 5 days on the start up it sounded like there was no oil in it for 1-2 secs.

The dealer has used Castrol edge 10w-60 fully synthetic oil,the car has never made this sort of sound before it was serviced.

I know the oil is thick so I am a little confused as to what made the car sound like a sowing machine.
