If You have a Northstar engine, I’ll do the work! The common and most expensive issues for Cadillacs is overheating, coolant loss, oil leaks! I do modifications to eliminate head gasket issues. I do lower end resealing to eliminate the oil leak problem. Northstars, 4.0 and 4.6 are also found in Pontiacs, Oldsmobile and Buicks. I have a base price for either issue and sources for redesigned parts to ensure the factory flawed design is overcome.
For consultation on procedure and price, I can be reached at (316) 789-3762.
