Hi, I’m getting parts ready to get the rotating assembly balanced for my stroker build and I have noticed that three of the pistons have some marks on them. one has a gouge on the face that quite a scratch. Another couple have tool marks on the skirts that I’m more concerned about as there is material protruding from the skirt that may damage the bore? any opinions? I’m thinking that best case is that I can clean up any rough metal and smooth anything proud with a dremmel. Not sure if I may just need to get some replacements though.

So I am now the 10th owner of JohnWs ix touring. So far so good, it's got a lot of miles under its belt, but has been given lots of love so wears them well. It's lpg converted and is currently returning about 25mpg on gas which equates to a little over 50mpg which is way better than my petrol 525iat. It's got an odd problem which seems to just be on startup when using petrol that sometimes it is really lacking power, but when the gas ones on the power kicks in. John kindly supplied a blue temp sensor so I'll change that in. I've also purchased a trans filter for an oil change and some filters: oil, cabin and air. So far just fitted the air filter as it's an easy win. Other problems are: 3rd brake light (factory fitted option) does not work - is this an mot fail? Door tweeters exist but seem to do nothing- do I need to make a crossover and splice them in behind the kick panels? Instrument cluster odo reset not working, lights out and dodgy fuel gauge - Geoff may have kindly sourced me a replacement cluster Rusty hole it the roof at the rear where a previous aerial was - I'll pro get a dab aerial and fit it as in my old touring. Rust creeping in a door bottom and arches. Seems a little low on power when trying to accelerate up hills, it may just be the extra weight of the transmission it's lugging. Other than these items it's great! It's had a decent re spray, electric seats fitted, auto dip mirror, map lights front and rear. The 4wd certainly gives massive confidence in the corners and gives eager handling along with the rack and pinion steering. For the engine oil change opine oils and other sites seem to recommend 10w40 semi, from the records it looks like it's had 15w40 and on here people suggest 5w30??? Given that it's a 190k engine should I stick to the 10w40 "dino juice" ? I'll get some pics up soon

I have finally started the tear down for engine overheating investigation and stroker build on my 525ix. It says in the Bentley to remove the transmission (auto), but I have also read that it's easier to take it out attached to the engine. Does anyone have any experience of this? also any ix specific tips would be useful and massively appreciated. This is a learn on the job project
