On my "02 Avalanche series III I have water in my v-drive. I think I've narrowed down where the water is coming from. On the top of the v-drive sea water comes in, cools the v-drive oil (via a small cooling tube) and the heads to the impeller. On the top of the v-drive is also the dip stick. This passes through the v-drive cover. I removed the cover to troubleshoot a flow problem I was having with a fake lake (different problem). Before I reinstalled the cover, cleaned the matting surfaces and used some RTV gasket maker to replace the gasket I destroyed. Checked for water leaks next time out and no water leaks... GREAT! Well, not so great. I was so focussed on preventing water from leaking, I forgot to ensure no water got into the dipstick hole. As I was checking fluids before our next trip, I noticed my v-drive oil was milky. So I drained it...a lot of it! Filled and drained it again. Oil started clearing up so I filled it a third time and now just waiting for the weekend to go run it again. Other posts I've read have said it takes 5-6 times out and flushing before the oil will be normal. I'm ok with that (I've become a pro at filling and draining!). My question is do I need to be worried about bearings, bearing surfaces, bare surfaces rusting inside the v-drive? Do need to have my v-drive rebuilt? Or have others had similar experiences and after flushing ran with it without a problem? V-drive seems to run just fine right now....thanks for help!
