I trust Jeff with my car & his honesty! He became my mechanic one year ago. I wouldn't have anyone else service my car!

Fantastic experience! I didn't know all of my truck's problems, but John helped me with whatever he could today, and let me know what needed to be replaced. Thank you!

He got here about 20mins early. He got right to work, he was quick and accurate. I will use him for all my work. Also I read a review about him being in a beat up car, that’s common sense for a mechanic because they fix cars so they can have a car a lot longer than the rest of us who know nothing. Don’t judge a man by his car when u need him to fix yours

He was good with the inspection--however, I was given the impression that Your Mechanic would be able to do the work for my truck. I did get an email to let me know that the company could not do the timing chain replacement. So for $80 I got a roadside inspection but no repair. I'm not sure what a shop would have charged for the same service. Richard is polite and he came early. But I think trying to have consumers do their own car diagnostics is a mistake and certainly not worth $80. I e-mailed your company with my own idea of what is wrong with my truck and I wasn't even close.

Graham quickly diagnosed the problem with my car and gave me an honest assessment of the issue, that along with some good advice on how to get the repair done right for as little cost as possible. That honesty, combined with his professionalism, friendliness, and obvious expertise, made this the best experience with a mechanic that I've ever had. Much appreciated!

Noise from engine or exhaust Inspection Service

Your car’s engine makes quite a racket. Some sounds are music to the ears like the exhaust note of a finely tuned V12. (Some manufacturers have resorted to placing speakers under the dash to simulate the sound.) On the other hand, some are cries for help, such as the jolt of a backfire, the snake-like hiss of a ruptured hose, or the incessant tapping of a defective lifter.

Common reasons for this to happen:

Here’s a guide to engine noises and some potential causes.

Whirring

Description: A vibrating or buzzing, much like the sound a window fan makes when turned on.

Cause: A whirring sound that changes in relation to engine speed could indicate trouble brewing under the hood. There are a myriad of possible causes, typically on belt driven accessories or the belt(s) themselves. Your mechanic will start by listening to the bearings of your alternator, idler, and tensioner pulleys. If no problem is found, the water pump is a likely culprit.

Hissing, Gurgling, and/or Sizzling

Description: Hissing sounds like air or steam escaping from a pipe or hose. Sizzling is like a slice of bacon in a hot griddle.

Cause: These three sounds often go hand-in-hand with an overheating engine. The hissing means your cooling system has possibly developed a leak. Gurgling sounds like a coffee pot percolating, and is the result of coolant boiling (which is abnormal in a properly operating system). Sizzling is the result of that coolant or oil landing on a heated engine component like, say, the exhaust manifold. The best course of action is to pull over as soon as safely possible, let the engine cool down and call a mechanic. If the car isn’t overheating but is still hissing, other possible maladies include a clogged exhaust and catalytic converter, but these are usually associated with more noticeable problems driving.

Loud Exhaust Note

Description: We are not talking about a throaty, grumbling, wonderfully musical exhaust note. No. We are talking about loud noises that occur unintentionally and suddenly.

Cause: The most likely perpetrator here will be a broken muffler or exhaust pipe. If a loss in performance accompanies that noise, then the problem is likely something deeper, possibly a cracked exhaust manifold or broken catalytic converter.

Backfires

Description: A blast from an M-80. Technically, a backfire is fuel detonating outside the combustion chamber. It can occur in either the intake system or the exhaust system, depending on the cause.

Cause: The most common is moisture or water in the fuel system. While your car’s gas tank may be tightly sealed, H2O can still seep in as the result of condensation caused by changes in humidity and/or dramatic swings in outside temperatures. The fuel filter should remove it, but some water can get by, especially if the filter is old. An unbalanced air-to-fuel mixture is the suspect of interest here, and may be from leaky vacuum hoses or a malfunctioning air intake valve.

Sputtering

Description: Imagine a jerking action from the engine and/or powertrain. The engine indiscriminately loses power, or rpms fluctuate, as the driver accelerates.

Cause: An incomplete combustion event. While this doesn’t sound dire, it can cause serious damage to other engine components, specifically catalytic converters. On 1996 and later models, a misfire will typically be accompanied by a flashing check engine light.. Have the technician check the ignition system, not just simply replace the spark plugs. This includes examining the ignition coil, rotor, cap, and wires (if so equipped).

A blocked or malfunctioning fuel injector will also cause your car to sputter. In some cases, it may be accompanied by a steady clicking sound.

Tapping or Clicking

Description: Imagine the sound made by a watch's movement or a ratcheting wrench. It’s a metallic tick, as though someone is striking the inside of the engine block with a metal stick in a rhythmic manner.

Cause: When tapping is engine related, it is usually more pronounced at idle, and increases in speed with engine RPM.. It may disappear at high speeds. In this case, it is probably upper valve train or tappet noise caused by either low oil pressure, excessive valve clearance or a defective hydraulic valve lifter.

The most common cause -- and easiest to remedy -- is that the engine is low on oil. Another answer is that there is some blockage in the system. Culprits could include a worn or damaged oil pump or a clogged oil filter. If you haven't had your oil and filter changed in a while, consider doing so immediately.

If it's not an oil issue, it's potentially related to the valve train, as we stated above; i.e., a serious internal engine problem that is preventing normal oil pressure from reaching the upper valve train components.

Spark Knocking (Preignition)

Description: A light, metallic knocking sound, usually under acceleration.

Cause: Knocking is most commonly attributed to improper ignition timing, lean air/fuel ratio, overheating, or improper fuel octane level.

It's a common misconception that there are benefits to using a higher-octane gasoline in your vehicle than the owner's manual specifies; however, using a lower-grade fuel can very well produce engine knock.

Bearing Knock

Description: Bearing knock is typically a deeper tone, directly related to engine RPM.

Cause: It is typically associated with excessive main bearing clearance (a regular, rumble-like knock), worn connecting rod bearings (sharp, irregular knock).Bearing knocks usually involve labor-intensive repairs. The good news is, regularly performed preventative maintenance (oil and filter changes) will typically prevent bearing damage from occurring for the life of your vehicle.

What to expect:

A top-rated mobile mechanic will come to your home or office to determine the source and cause of the engine or exhaust noise, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.

How it's done:

The mechanic will typically begin by listening to identify the general source of the noise. In the case of potential belt or accessory noise, a stethoscope is used while the engine is running to listen to individual bearings under load. A noise that has a corresponding drivability concern (misfire, preignition), will usually be approached with a scanner or code reader, to determine which electrical system may be malfunctioning. Internal engine noises (knock, tick) will almost always begin by checking the engine oil level. If the oil level and condition are acceptable, a more extensive disassembly may be required.

How important is this service?

Given that a noise can indicate a minor or major issue, it's wise to book a mechanic to perform an inspection as soon as possible and learn promptly what's at the root of the engine or exhaust noise.
