What did you do with/to your Boxster today?

[skucera]

Qingdao, I like your solution. I'm going to have to rummage around my local scrapyard to see if I can find a couple of those for my car. Both of my windows started to not drop last week when the smoke was at its worst. I'm a little tired of pushing my window down that quarter inch before closing my door with the top up.

Thanks,
Scott

Replaced spark plugs, new spark plug tubes, installed new HT coil packs, and did an oil and filter change. Now she purrs with no rumble at at 3000 rpm. Hopefully the oil leak goes away too with the new spark plug tubes. Will find out tomorrow morning, to see if there is a spot on the floor at the right side by the tire.

Hmmm... I still have the light rumble on 3000rpm after fixing the vibrations on the same rpm by swapping engine and transmission mounts.
Also, have changed the plugs, plug tubes, oil & filter, but not the coils. Could it be that the coilpacks would be reason for my car's rumble?

These cars make a rumbling sound right at 3,000 rpm, due to a resonance in the engine. Mine does it, but I only hear it while in the lower gears where the road noise is lower.

Sounds like exactly what is with my car has. Light rumble but it's annoying, since speeds I drive here is fairly much on close to 3000rpm. I'd like to think that Porsche cars would run smooth thru out the rpm - at least my two previous ones were (1986 944 and 1985 Carrera 3.2).

Coil packs are one of the items that was highly recommended to fix this problem. I've only put in about 50 miles since doing this service, but from what I noticed, the rumble is gone. Also, the Pelican site says to change the spark plugs every 10000 miles, so if you've got more than that on plugs you currently have, I would change both of them at the same time. Your already in there, so why not. I had over 20k miles on the plugs and when I took them out, the tips were almost gone. LOL. Good Luck.

I changed the plugs approx 5000miles ago and the current plugs condition is very good. Car runs awesome besides the light rumbele at 3000rpm.

No CEL's of any kind of, not even pending ones. I have Durametric and that can't find any issues - at least so far.

Also, regardless of the weather (dry and sunny, humid, misty, heavy rain, etc.) car runs real well. My understanding is that if coilspacks are going bad, most of the time it would be related to cracks on the coilpacks and cause problems especially on the wet weather driving conditions.

Do you mean the exhaust resonance at around 3.000 rpm or are there real vibrations somwhere in the cabin or stearing or somewhere else noticable?

What engine mounts did you use? The original Porsche front mounts have a new design. This mount might cause the problem with vibrations in my car. But my vibrations are in every rpm range.

The rumble is evident especially when I lift the gas above 3000rpm for lowering the car speed - the at 3000rpm it shows up. Only very seldom it is so strong that I could call it a shaking, but it is not on the steering only. It's rather on the car body, so I'd expect it to came from engine since the speed of the car has nothing to do with it - happens with every gear at same rpm.

Ordered the engina mount from design911uk and it says on the receipt that "This product supersedes Porsche's old part numbers: 98737502304"

Transmission mounts are branded 'Rein' that has been commented to be a good choice on few of the Porsche forums I read.

After driving it a little more yesterday, the rumble may still be there, especially when I downshift to lower gears, it is noticeably less rumbling than before though.

I want a rumble at anything above 3000rpm! If I don't get that growl or famous boxer motor rumble something is wrong.

The motor and exhaust noise is what makes these cars notoriously fun, stop worrying and just drive it!

I replaced the coil packs about 8k miles ago with a set my friend gave me, he said they were only about 30k on them. I think the combination of not changing the spark plugs and using old coil packs may have been my issue. I'm not gonna mess around with used ignition parts anymore. LOL. Good Luck.

Seriously? 10K?? I get well over 100K on my Chrysler and Subaru spark plugs!

psh lightweights.

I do about 5 k on my RX7; then I torch them and brush off the carbon build up.
