The braking system on your car requires a lot of pressure. The vacuum booster is one of the main sources of this pressure. This booster will take the pressure that...
The engine in your car can only run when the right number of controlled explosions are performed. During the explosions, there are a number of gases that are produced that will...
The EGR valve is the heart of the emissions system on an engine. EGR is an acronym for Exhaust Gas Recirculation, and that is exactly what it does. This wonderful...
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...
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 to wiring harness issues, not to mention mechanical...
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...
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...
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...
If you have an engine that is running rough and misfiring and the exhaust is sucking in sometimes then you may have an exhaust valve that is sticking open. You should have a compression test to the motor. The valves...
Of course, first confirm that the plugs are correct for the engine. The wrong plugs, and/or missing crush washers, can cause interference with the piston. If the plugs are correct, the cause of the mechanical interference can sometimes only be...
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...
If you didn't change plug wires, cap and rotor, those could be causes. Also, the distributor itself would have to be tested. As far as the fuel injectors, you just want to be sure they are actually getting a signal,...
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. It is possible that you have a bent valve but instead you may have a warped valve seat. Whether or not that is the case what is most likely causing the lack of compression in your engine is a...
Check the combination valve on the brake system. If the valve is sticking, then the fluid could be getting trapped and not returning. To check this valve, loosen the brake line on the back side of the valve (the side...
Hello, thank you for writing in. Standing on the passenger (right) side of the vehicle, you will want to look under the air duct between the intake and the air filter. Below it you will see two connections. One is...
The valvetronic motor is stuck or not functioning properly and causing the engine to not start up. I recommend replacing the valvetronic motor. The motor is designed to cycle itself when turning on the ignition, so it is good to...
Hi there. If the valvetrain is out of adjustment or the lifters are stuck and making a tapping noise on the top of the engine, then that could damage the engine when driven. I recommend changing the engine oil and...
Hello - this is a challenge, since you have multiple serious problems. The P1259 problem is most likely what is putting your engine into "limp mode". P1259 in a Honda is a problem with the variable valve timing mechanism of...
Hi there - your Odyssey engines valve train is adjustable, and requires an occasional adjustment, or you get a bit of clicking as you have noticed. Make sure the proper engine oil is in the engine, and that there is...
Hello - your Windstar has composite plastic valve covers, as do many engines these days. While being lighter and less expensive to manufacturer, they tend to get brittle with age and heat cycles. A momentary surge in crankcase pressure, or...
Hi there. When it comes to having a loss of compression in an engine, there are 4 locations that can contribute to the leak. Locations: Bent or burnt intake valve Bent or burnt exhaust valve Hole in a piston...
