Turbo Rebuild???

[dragracer3346]

When is it time to rebuild a turbo? My 2000 f350 ccd has about 176,000 mi, and doesn't have the power I think it should. I have a 4" exhaust with free flowing muffler, diy intake, and a Superchips programmer. I have noticed the inter-cooler pipes are oily both by the inter-cooler and the turbo, so I am thinking my seals are leaking? is this possible that by rebuilding the turbo and buying a new compressor wheel that this could restore the power it should have? I used to have an early 99 psd and it had noticeably more power than this truck, and had 300,000 mi but also had a new turbo. Thanks in advance for the advice

The oily residue is normal. That'd be your Crank Case Ventilation (commonly referred to as CCV). The crank case pressure is relieved (stock) back into the intake before the turbo therefore causing the oily residue which travels beyond the turbo and can be seen in and sometimes around the intercooler boots. Some have modified their CCV to eliminate what youre seeing. All in all, youre good.

In reference to your difference in power, that may just be your chip. Hard to say with the variable amounts of power from different products in what youre experiencing. The 7.3 is an old plow horse either way. Slow and steady.
