well my pt3000 blew the top panel 5/8 apart. broke right down the welds. how common is this? it blew only making about 22lbs of boost. i just had a turbo failure right before this pass. i cleaned it out due to oil being in there. could left over oil residue cause this? there are no restrictions in any of the pipes. was running twin 88's and now switched to twin 91's. 540cibbc. on gas. all data looked good.any ideas?
