Ranger, Edge: Ron, I am trying to glean some info on what

Customer Question

Hi Ron, I am trying to glean some info on what I think is a damaged head gasket on my 2001 Ford Ranger. the check engine light throws a p0304 and a p0402 code and there seems to be a little brown color in my coolant. But it doesn't seem to run rough at all and has power even up hills. I had a mechanic take a look. They did a compression test and said only cylinder 5 was low at 80psi and recommended tearing the whole engine apart to inspect the cylinders for 2,800 bucks. I thought I would get some other advice before taking extreme measures

Hi. What engine is in your Ranger? a 3.0?
Customer: replied 1 year ago.
It is a 3.0 and just for further info I just drove it a short distance and noticed the check engine light went off
Expert:  EricFromCT replied 1 year ago.
Ok. The brown in the coolant could be normal if the coolant has not been replaced recently. A lot of times you can rev the engine and see bubbles coming back into the overflow if the headgasket is blown.

Have you tried to replace anything yet to fix the p0304, cylinder 4 misfire?
Customer: replied 1 year ago.
No I haven't done anything yet

The 3.0 is known for having some valve problems. If it was low on compression on a cylinder a cylinder leak test should be performed. If you are testing for headgaskets a block tester can be used in the cooling system to check for exhaust gasses. Thanks.
