Check the weep hole on the water pump and also the thermostat housing flange. Also check your oil for evidence of coolant as this may indicate a leaking oil cooler. Cheers!

Pat, what is the "weep hole" and why is it there? I noticed I have a large leak SOMETIMES in my new 97 stroke. It wasnt there yesterday or the day before but a couple days ago it was..and dripping bad. seems like its intermittent. around my tstat housing gets wet and the temp sender too.

Fatk22, look on ebay, Theres a guy who sells a lot of them. I got one for my old truck and it was real easy to rebuild, new bearings and thrust collar and the whole deal. If I were you, id get a new ball bearing turbo.

The weep hole is on the bottom of the waterpump snout. Any coolant leaking past the shaft seal will drain out this hole. The T-stat housing is also a big leaker and can be a PITA to get leak-free. A new gasket and making sure that the "housing ears" (where the bolts go) are slightly bent upward so that the gasket is compressed when the bolts are tightened. Cheers!

Don't worry about any other problem until you find out where the coolant is going. If no one has been keeping up the additive in the coolant you might have a junk block due to cavitation.

Don't mean to be the voice of doom but cavitation damage is a real possibility if the SCA levels were not maintained. Special coolant testing and maintanance is required with the PSD. What was the reason for the rebuild?

Lot's of good reading if you use the search function.
