Engine replacement
When an engine has failed internally, replacing it is often the fastest way back on the road. We inspect the engine, confirm the failure, and give you an estimate for a replacement engine before any work begins.
Overheating is an emergency
If the temperature gauge climbs into the red, pull over and shut the engine off. Driving an overheating engine can warp a cylinder head or ruin a head gasket. See cooling system service.
Start with the check engine light
Many engine problems announce themselves with a check engine light long before they get expensive. See check engine light diagnosis.
Frequently asked questions
Should I repair or replace my engine?
It depends on the vehicle, the damage, and how long you plan to keep it. We inspect it and explain the repair or replacement that fits.
What does a ticking engine noise mean?
It can be low oil, a valvetrain issue, an exhaust leak, or normal injector noise on some engines. Check the oil level first, then have it inspected.
Why is my car losing oil?
An external leak from a gasket or seal, or oil burned inside the engine. We check for leaks and smoke to tell which.
