Tahoe compressor leak?

Barrnone on Sun August 17, 2008 5:35 AM User is offline

Year: 1995
Make: Chevy
Model: Tahoe
Engine Size: 5.7
Refrigerant Type: 134a
Country of Origin: United States

I have been tracking down leaks for awhile now, with help from this forum I have been making good progress, Thanks!

I added dye to the system, this showed a leak around the body of the low pressure switch on the accumumlator, replaced it. A couple of weeks pass and vent temps start rising fast, can't find any new evidence of dye showing including in the water drain from the box. In frustration, and a little lack of patience I decide to evac and recharge even though it shows a small vacuum leak. As it is recharging I happen to here a hissing noise from the compressor area, so I start really checking things out, the only thing that I notice is an oily residue around the clutch and face of the pulley, there is no evidence of dye. So after all that, should the clutch show any signs of oil? If it should not and it is coming from a leak in the compressor does it take a while to migrate out so that signs of dye might not show up yet?

Thanks for all the help.

Sounds like you have a shaft seal leak. Seals can be replaced with the proper tools which can cost as much as a new compressor.
