If you have a valve cover leaking oil onto the spark plugs then it can cause a misfire. This does not mean the leaks are the cause but a possible cause. I would recommend having a mechanic like one from...

Hi there. Typically the issue you're describing is ignition or fuel delivery related. It could be as simple as a crankshaft sensor that is faulty or as complex as a fuel / air mixture issue caused by a faulty mass...

As a mechanic that has worked on cars for over 35 years at both dealerships and independent shops I can tell you that most repairs done to a car will not cause another problem unless it was directly related to...

Hi John. Thanks for contacting us today. Oil in front of the motor, near the crankshaft pulley, is often from the front crankshaft seal. Although this is not normal, it is common with an engine 20 years old. I'm not...

You most likely have a fuel filler nozzle that has an outer hose with an outer hose in it. If the inner hose comes off of its mounting at the inlet of nozzle then it will restrict the fuel trying...

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...

Hi there. If your vehicle is not equipped with the immobilizer system, but yet it is causing your vehicle not to start, then there is a problem with the engine control module. Most of the time the module can be...

The lack of heat being generated by your system may indicate a clogged heater core. The [heater core]((https://www.yourmechanic.com/services/heater-is-not-working-inspection) is a small radiator like unit that circulates the hot coolant from the engine through the heater core which then uses this...

What you are describing sounds like a faulty starter solenoid. A faulty starter solenoid will generally produce a clicking sound when turning the key. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity...

Hi there. From the description you have provided, your vehicle's P0335 code is not being corrected by replacing components. Assuming, the replacement components are correct by application and of OEM (original equipment manufacturer) quality. It could be, the crankshaft reluctor...

Hi, thanks for your question. I'd be happy to help. The diesel battery may be heavy duty compared to the petrol engine. The two batteries should be compared for size and height to be the same and the terminals should...

Hi there. Diagnosing a vibration sound is very difficult to do remotely, which is why most mechanics will test drive your vehicle first to attempt to replicate the sound you're experiencing. However, in most cases, the type of sound you're...

Hi there. The first step would be to have the front end inspected to see if the upper and lower ball joints and control arms bushings are worn out and need replacement. If something is worn out and cannot be...

Hi there. From the description you have provided, leads me to believe the slow and no crank may be, a battery and/or battery connection issue. It could also be, a faulty starter relay or starter concern. Proper diagnoses should be...

Hello. The truck is designed to have a lower oil pressure at lower engine speeds and more pressure as the engine speed is increased. This sounds like it is normal operation of the gauge and oil pressure in the engine....

The cost to replace the engine may exceed the value of the vehicle. It will cost less to replace the engine with a used one versus overhauling the existing engine.

You are getting codes to each and every major sensor on the engine that is needed to run your motor. You either have a major malfunction with the ECU or a problem with the harness not being wired correctly. You...

Hi. If the code is still present after both sensors have been replaced, and the engine is stalling, further diagnostics is needed. First of all, a new sensor doesn’t always mean a good sensor, especially aftermarket ones. Check the sensor...

You will need to check the engine intake for vacuum leaks and if not then replace the sticking idle control valve and then relearn the idle by disconnecting the battery and then reconnect after 10 minutes. Start and hold at...

It sounds like your fuel pump is not working properly. The engine is not getting fuel if it has to crank that many times and still barely starts. I would recommend getting your fuel pressure tested by a certified mechanic...

Ideally, you should have aligned the marks before you removed the timing belt. It sounds as though everything is completely disassembled already. This makes things a bit more difficult. I would only recommend assembling it the same way as you...

Hello...The vibration problem that you are having can be resolved and your question is a good first step toward resolving it. There appears to be four (4) mounts in your application. Presumably you replaced all four if you suspected the...
