Hi Stephan, I think you can still recover this and use it since the damage is not a large portion of the flange. So here is what I think may be a recovery plan for your bearing housing: 1. First, mill a clean opening between the remaining good bolt holes as shown by the yellow liines 2. Machine up a replacement part that is a similar size...it doesn't have to fit the missing sector perfectly, because it is just acting as essentially a thick washer. 3. Machine up a clamping plate, similar to what is used on some other turbos to clamp the bearing housing, as shown in the image to the lower left. Since the locating feature appears to be the fit between the bore and heat shield, there should be no change there. The bolting flange, will off course now rely on the overlap of the clamping plate, but by using a good steel for the plate, it will have much more tensile capability than the original nodular cast iron, so there should be no concerns about the blow off load capability. Just a suggestion to maybe help save you money and get you going. Good luck! Chris

Hello Chris! Thank you for your input,highly appreciated my friend I have put together the compressor housing and the compressor back plate, these Will be put to storage together with the mambatek compressor wheel for the future! Work continue trying to Free up that stucked heatshield in the turbine housing without hurting turbine wheel...that might be Difficult because i have to get in between the turbine blades with Metal drifts trying to Free the heatshield (It is made of cast iron) and has become one with turbine housing....

Hi Stephan
Heat the entire assembly , and put ice into the heatshield , it should contract away from the thicker scroll
Cheers John

Hello guys! A update on my project, today i managed to separate the turbine housing/heatshield, i had to use a press and press on the turbine wheel...forcing the heatshield out,the turbine wheel seem to be ok i Think,can not see any damage to it The heatshield look a bit sad after my violence to it trying to BONK it out with a drift,screwdrivers etc..... now i need to find a serviceable bearing housing!! Anyone in here might have such?

Hi Stephan
LOL.............most turbo parts are made in China , the major manufacturers have Plants there .
Its only a chunk of cast iron :-)
Cheers John

No that was NOT Good at all,infact it was devastating!! My thoughts are many now,how Good is a chinese replacement?what is your experience there John?.....a bearing housing is one thing BUT a turbine wheel is a totally different thing.
