LOL I found that one out with the hoses to my oil catch can... one of them dangled too close to the turbo (still about 10cm away) and it started to melt!!! Lucky the hose had metal reinforcment in it so it didn't all perish away :)

You are lucky, same thing happened to my turbo oil feed/return line but the hose metal reinforcement didnt hold, oil leaked out caught fire on the exhaust and the turbo starved of oil. eventually the bearings collapsed and cost me a HKS2535. So yea, be carefull with oil supply to turbo!!!

by the sounds and looks of it...the oil in and out is a pad type flange with the plain hole in the guts. Hence why you prob have adapter plates made up with like a hose tail on the end. braided lines and fittings wont do you any good unless you can then adapt them to the flanges or you find some a/m adapters ready to take fittings and braided lines. If im right, the only way i can see you getting away from the pad type setup is to tap out the two holes and put fitting directly into the turbo top and bottom and then get ya braided lines to suit....s/s teflon lined is the go:)

My old turbo was pad type oil in and out, had alot of those problems with it also. I reckon every turbo should be tapped for fittings straight out of the factory, even oil return.

Yep that is dangerous and dumb . I'd say the plate bolted to the top of the bearing housing is warped so not flat and won't seal oil in . That aside the use of rubber hose and wormald clamps is ridiculous given the heat in that area .

I would be removing that "adapter gadget" and flattening it with a big hammer .

Then I would be looking at the oil feed hole in the top of the turbos bearing housing to see if it has a thread in it . If it has your in luck and can screw an adapter fitting into it and then plumb a propper braided line or even steel pipe if you like . If its not threaded buy the two bolt plate adapter from Garrett or which ever turbo parts supplier you use . Then screw the threaded adapter or banjo and banjo bolt into the bolt on plate . Corky Bell has a chapter in his book Maximum Boost devoted to turbos and oil inc supply and drains . I suggest you read it .

Cheers .

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
