04 GMC Envoy 4wd

Hello, If your mechanic is telling you there is a problem, and you do not agree with it, then get another opinion from another professional. If you have no measurable oil pressure, then you can't run the engine. Basically it's a matter of you trusting the technician or not. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Sorry to hear about your Envoy giving you the cold shoulder. If you had fuel in your oil, it could be a sign of a leaky fuel injector or a failed fuel pressure regulator, causing fuel to seep into the crankcase. Running with contaminated oil can cause severe internal damage, including washed-out bearings and cylinder walls, leading to low compression and oil pressure issues. Since your mechanic mentioned no compression and low oil pressure, it's a good indication that the engine might be toast. However, before declaring it a total loss, compression and oil pressure tests must be done to confirm the diagnosis. If the engine's truly blown, replacing the fuel pump or oil pump won't bring it back to life. If you need any further advice or if you'd like any help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
