tech says intake leaking,but i have had no problems with motor runs fine i replaced old thermostat that was sticking 2 weeks ago but have no others problems with motor would there have been obvius signs of a intake leak

 

So if you see no problems then why take the techs word for it? Try another shop.

 

are ya losing coolant?

 

yeah if your loosing coolant its probably burning it

 

if the intakes leaking your either loosing vacuum or burning coolant.

 

check your oil! the 350 in my 97 had a bad intake gasket right in the very front (drivers bank) and it started slow then began dumping massive amounts into the oil. or you could be burning it.
