The best advice that I can give you is this. Do not drive your car if it is overheating or has no oil pressure. If you see a light or gauge for high temperture or lack of oil pressure, pull over safely, as quickly as you can. Driving a overheated car or one with no oil pressure will destroy the engine in moments. I have priced engine replacements from $1500.00 to $7000.00 with the average remanufactured engine at $5000.00 installed!
