when cars do a lot of short journeys or never get to warm up completely, condensation mixes with the oil and forms an emulsion, this then gets cooked when the car does a longer journey and gets really warm. Only an opinion but used to see this a lot inside rocker covers and pollution control systems.
to me that looks like the kind of sludge you sometimes find in the top of an engine, often caused by short journeys, its definately nor black!
Hi Steve, I had a Boxster with these symptoms exactly, start fine in the morning, warm up and then idle roughly, give it some throttle and seemed to run fine. On the odd occasion it wouldn't do it at all. I think it turned out to be the AOS, if I remember correctly you can effectively blank off the AOS, there is a tube coming from it which you can disconnect and then blank off both ends to test it, not sure if its the same on the 911. I know that this might not explain the codes though. Only other thing that might be worth a go would be to clean/disconnect the MAF, but again not sure how this could relate to codes. Hope you get it sorted.
Did you get this sorted?
timbo replied to timbo's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)All sorted now, shows what corrosion can do, thanks to Lauren for help with colour codes, went with what came off the car in the end.
timbo replied to timbo's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)Thanks Loren, since replacing the rear springs, which you kindly helped with checking the colour codes, I seem to have a rather high ride height. I can get at least 3 of my fat fingers between the wheel and the wheel arch. I'll try to check these values tomorrow, but seeing as you and OPC agree on the colour codes I'm wondering what could cause this. I haven't fitted the fronts yet but am expecting the same issue. Just hope I can locate the required measuring points. Do I assume C2 and C4 values are the same.
Hi everyone, does anyone have a C2 mk1 with standard springs and 18" wheels who could measure the distance from the ground to the inside of the highest part of the wheel arch, front and back. I'm guessing ROW models as i think US cars are higher because of the bumperettes.
timbo replied to timbo's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)Thanks for that, there are in fact threaded holes below the plate but perhaps its for another application. Having just replaced what I thought were stock springs with stock springs I'm a little concerned the height on mine is higher than I'd like so I may have to modify the springs. Interesting your top bolts seem to have washers under them, mine don't.
timbo posted a topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)So in a previous post I mentioned that I had two springs break while the car was parked up, today I replaced the rears. While in the car came across a split aluminium plate with two holes in it,should there be bolts in there? The other pic is what looks like the remains of a plastic fitting, (tracker?) anyone any idea what it was.

timbo replied to timbo's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)Thanks Loren for the speedy reply, was a little concerned they had sent the wrong ones as they are different to what is on the car already.
timbo replied to timbo's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)well we've had some cold weather, but not that cold, -5 or so for a few days, but not driven.
timbo posted a topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)Can any one help me with front and rear coil spring colour codes, should they be the same for front and back? the replacements I got from the OPC are different.
A little while ago came to use the car one day and heard what sounded like someone dropping a spanner on the road. On inspection it turned out to be the NSF spring broken. The car has sat in the garage since then, about a month, new springs ordered and I've just waiting for some decent weather. I've been in and out of the garage since then, there was nothing obvious in the car's stance, still looked ok, until today, really cranked over to the near side. On inspection the NSR spring has also snapped! a month later and no mileage. What are the chances of that happening eh!! ....... its a bit of a bugger because I probably wouldn't have gone with OE replacements and maybe lowered it a little. Just seemed a little strange that both springs broke without actually being on the road. I should add that before driving the car the first time a spring broke I noticed some black paint on the floor where the NSF spring was, I think it broke while in the garage.
timbo replied to mocohead's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)have you checked the cat brackets, just saying as i recently replaced the water pump and started the car without this bracket, considerable vibration, also noticed the bracket was cracked. after fitting the bracket no vibration.
how old is the battery?
