Ford expadition and put on a new head gasket now you have no horse power?

It sounds like you're having a serious issue with your Ford Expedition after the head gasket replacement. Losing all horsepower is a major problem and could be due to a few different things, even if the head gasket replacement itself was done correctly. Here's a breakdown of potential causes and what to do next:

Possible Causes of Power Loss After Head Gasket Replacement

1. Incorrect Head Gasket Installation: Even if the gasket was new, it could have been installed incorrectly, leading to a leak or improper sealing. This is the most likely culprit if the problem occurred immediately after the replacement.

2. Damaged Cylinder Head: The cylinder head itself may have been damaged during the removal or installation process. This could cause a compression leak, leading to loss of power.

3. Timing Issue: If the timing belt or chain was disturbed during the head gasket replacement, it could be out of sync. This would prevent the engine from firing properly.

4. Damaged or Clogged Fuel System: While unlikely, the repair process could have accidentally damaged a fuel line or filter, or there may be a clog preventing fuel from reaching the engine.

5. Other Engine Problems: The head gasket replacement could have masked pre-existing engine issues, and the power loss is a symptom of a different underlying problem.

What to Do Next

1. Re-check the Head Gasket Installation: Have a trusted mechanic double-check the head gasket installation to ensure it was done correctly. This includes checking the torque settings of the head bolts.

2. Inspect the Cylinder Head: Ask the mechanic to inspect the cylinder head for any cracks or damage that might have occurred during the repair.

3. Verify Timing: Make sure the timing belt or chain is correctly aligned. If it was disturbed, it needs to be reset.

4. Inspect Fuel System: Ask the mechanic to inspect the fuel lines, filter, and fuel pressure to rule out any problems there.

5. Diagnostic Check: If the above checks don't reveal the cause, it's time for a comprehensive engine diagnostic scan. This will help pinpoint any underlying issues.

Important Note: It's crucial to find a qualified mechanic experienced with Ford Expeditions to diagnose and repair the issue. Attempting to fix it yourself without the right knowledge and tools can further damage the engine.
