I believe that you are right: your drive belt is broken. Unfortunately, this happens to everyone at some point. The best course of action is just to replace the belt. I don't believe anything happened to any internal engine parts...

Hello there, thank you for asking about your 1991 Geo Storm. After your comment about flooding the parking lot with steam, this symptom leads me to believe you may have a failed head gasket. A failure in this seal will...

When your car begins to knock due to a lack of oil, this could mean many different things, such as broken or bent valves, a bad camshaft, rod or main bearings (https://www.yourmechanic.com/services/center-support-bearing-replacement), and many other different things. As you may...

This may be a sign of a failing idle air control valve. The idle air control valve is located on or near your intake manifold that monitors the air intake as it is mixed with fuel prior to being injected...

It sounds like one of the shift solenoids is not functioning properly. I would recommend having a technician come out from YourMechanic and pull the codes on the computer, replace the shift solenoid (https://www.yourmechanic.com/services/shift-interlock-solenoid-replacement), and change the transmission filter and...

There are usually two different issues that cause the engine to stall or reduce RPM in situations like this. The first thing I'd look at is the idle control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) or sensors that monitor the fuel system. The second...

Your low-pressure reading of 80-85 psi is a bit high. Even with ambient temperatures of 100 degrees, a reading of 50-60psi is normal. A few things can be causing that high reading. First, if the system has been charged recently,...

Hello, thank you for writing in. The cost of replacing your valve seals is going to vary by the technicians available in your area, and the availability of parts. Unfortunately, accessing the valves can be very difficult and its can...

The purge valve is mounted on the engine and you will see hose connections from the valve to the intake manifold as well as a wire harness connection. The purge valve should be tested to determine if it is actually...

The protocol depends on the codes that have set, which are quite varied. Problems with these systems on your particular model and year can stem from blocked oil passages to failed solenoids (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-variable-valve-timing-vvt-solenoid) to wiring harness issues, not to mention...

With the age and mileage of your vehicle, it would probably benefit from a throttle body service including cleaning the idle air control valve. Over time, oil and carbon build up on the throttle blade so it does not sit...

Hello. The PVC valve shouldn’t cause your oil light to come on. Most likely, the problem is that the oil is low, which would cause the light to come on. The oil pressure could be faulty, which would also cause...

Hello there, thank you for asking about your 1986 BMW 635CSi. It sounds like you've checked all of the low hanging fruit. The previous owner may be right - some vehicles (only German ones come to mind) can develop a...

You need to pull out the coil and check to see if there is oil in the spark plug hole, or on the plug wire boot. If there is, then replace the valve cover and spark plug boots after cleaning...

Hello. You can try and clean the IAC valve, but if it is bad, it will need replacement. Cleaning the IAC valve would only be a temporary fix. The IAC valve is usually attached to the throttle body, and can...

Replacing the timing belt is not a job to take lightly. If you have never done one before, I suggest you get a shop manual. If your belt broke while you were driving, you probable bent valves in the head....

The KIA 2.4 liter motor is what is called an interference motor and this means it will bend valves if the timing belt breaks or jumps timing. You will need to have cylinder head removed and bent valves replaced if...

Hello, thank you for writing in. For exact specifications on tools needed and a step by step procedure, you will need to access a service manual for the vehicle. Typically you would expect to use a 12 mm socket or...

Hi, I will be glad to help you with this. If you already have a new cover, the required service is valve cover gasket replacement as that service already includes removal and re-installation of the existing valve cover and, in...

In your initial question, I did not know that valve damage occurred as a consequence of a failed timing belt replacement. The 4 valves that the shop "claims" were damaged might merely represent what they "think" was the extent of...
