Don't Blow a Gasket! (Valve Cover Gasket Replacement)

When you head out to your vehicle after it's been parked and notice oil leaking underneath it, that's something to have looked at right away.  Oil leaks mean your oil level is probably low and running a vehicle in that condition can lead to expensive repairs.

While there are many reasons oil leaks develop, one possibility is a bad valve cover gasket.  Vehicle engines have a cover bolted over the spot where the engine valves are, and that cover keeps the oil inside the engine. In between the cover and the engine is a gasket that keeps that seal tight.  But after many years of high engine temperatures and vibrations, that gasket or the bolts that hold on the valve cover can fail or loosen, and oil can leak.

You may see dirty oil on the valve cover in the engine compartment, near the spark plugs, or around the bolts that hold the valve cover on.  All those are signs of leakage and time to bring your vehicle in for our technicians to check out.

In some vehicles, taking off the valve cover and replacing the gasket is a relatively easy job. In some models, though, other engine parts are located near that part of the engine and must be removed to get at the gasket, so repair costs can vary widely.

The technician will measure to make sure the valve cover isn't warped so it can be reused. If it is warped, they'll recommend replacing it with the gasket.  

While the technician has that area of your engine accessible, they will also check to see if other components need replacing at the same time, which could save you money.  And because valve cover gaskets usually fail in older vehicles, the technician will check for other oil leaks then, too. 

One of the best ways to be sure your valve cover is doing its job is to have your vehicle regularly maintained.  The technician will periodically look over your engine compartment and make sure you know when things are showing signs of age and wear BEFORE they fail and leave you stranded.

Snake in the Engine (Serpentine Belt)

There's a belt that snakes through your engine.  It's even named for a snake, the serpentine belt.  It'll bite you when it breaks, possibly leaving you stranded.  So, it's good to know a little about this snake-like belt.

In early engines, there were lots of belts. They were used to convert the rotating power of the engine to turn a mechanical part.  But engineers had an idea.  Why not consolidate all those belts into one that ran a bunch of different parts simultaneously? Voila!  The serpentine belt.

It's found in the front or side of your engine unlike older belts which were often in a V shape, the serpentine belt has ribs on it which more effectively connect with the pulleys that power the other components.  A serpentine belt may power the water pump, power steering pump, alternator, and the air conditioning: all from one crankshaft. 

Now, all that's fine when everything is working well and the belt is intact.  But when a serpentine belt wears, gets loose, or breaks, it can affect many engine components at once.  Not an ideal situation. 

If you hear squeals coming from the engine compartment, see a battery light, or the engine overheats, those could be signs that your serpentine belt needs replacing.

The good news is that they usually last a long time, from 60,000-100,000 miles or 100,000-160,000 km.  Still, they don't last forever, and your vehicle's manufacturer usually recommends replacing them when they've gone close to the expected maximum.  It’s also recommended that you replace the pulleys and belt tensioner at the same time as they have the same service life. Regular maintenance and inspection of the serpentine belt is not only a good idea; it’s one of those things that you should not let "slip" by.

Road Trip? Check! (Trip Inspection)

After months of postponing travel far away from home, a lot of us can't wait to hit the road and scream "Road Trip!" again.  But how long has it been since the vehicle you're planning on taking has had a thorough inspection? And is it roadworthy for several days on the highway? Time to schedule a professional trip inspection in our service center. 

When it comes to long trips, before you go, make sure you can stop.  We can perform a break inspection.  Our technician will visually inspect your brakes for wear and how much life is left in the brake pads and rotors.  They'll also check your brake lines and fluids for fitness and fill.

If it's going to be a long trip, it's important that your engine stays lubricated.  The technician will see when the last time you had an oil change, check the levels and inspect the system for leaks.  If you are close to needing an oil change, it's best to have it done before the trip because no one wants to interrupt a vacation with an oil change in a strange place.  It's also better for your engine to have fresh, clean oil rather than driving with dirty, worn-out oil.

Comfort in any vehicle depends partly on the suspension system.  Our technician can examine shocks and struts so you can avoid an uncomfortable and potentially unsafe journey.  Oh, and you'll definitely want to make sure your wheels are aligned.  A long trip in an out-of-alignment vehicle can be a driving nightmare with potential steering problems and tire damage. 

A couple of little things some drivers take for granted are the engine air filter and wiper blades.  A dirty air filter can cost you money by reducing fuel economy; it adds up on a long trip.  And worn-out wiper blades can make visibility while driving in a rainstorm a blinding, unsafe adventure that you never want to experience, especially in unfamiliar territory.

If you're in the habit of having your vehicle regularly maintained, many of these items may be in excellent condition.  But considering the extra stresses a long road trip places on any vehicle, it's nice to have a set of our trained eyes give your vehicle a closer look. That way you'll be able to gaze YOUR eyes on sights like the Leaning Tower of Niles or the Gopher Hole Museum.

In That Case? (Transfer Case Exchange)

Ever wonder how all-wheel-drive or 4-wheel-drive vehicles get the power from the engine to the front and rear wheels? The magic happens in what's called a transfer case.  In some all-wheel-drive vehicles, it's sometime called a power take-off unit, or PTU.

Inside the transfer case is a set of gears.  And to keep those gears meshing smoothly, they have to be lubricated and kept cool.  What does that is called transfer case fluid. Depending on your vehicle's type of transfer case, it is filled with either an automatic transmission fluid, a gear oil that's a bit thicker or transfer case fluid designed to be use for your transfer case.

As happens with all lubricating fluids, the transfer case fluid has things in it that break down the older they get.  They have corrosion inhibitors, detergents and anti-foaming agents that keep the lubricant from getting air bubbles in it. Transfer cases don't have filters in them to clean out impurities.

If you don't have your transfer case fluid exchanged for fresh, you risk damage to the case, and that can run into thousands of dollars.  So the wise driver makes sure the fluid is changed according to the manufacturer's recommendations.  For many vehicles, that is every 30,000 mi/50,000 km, but some require it more frequently.   Your vehicle service facility can advise you on what your vehicle's optimal interval is.

During the fluid exchange, any metal filings that may have come off are cleaned off of the drain and fill plugs that are usually magnetized to catch the stray metal pieces.

If you hear grinding noises coming from under your vehicle or if it is having trouble shifting gears or going in and out of 4-wheel-drive, those could be signs your transfer case needs service. In that case, have our technicians check it out.  The best plan of action?  Keep your transfer case fluid maintained and it should keep you heading down the road for years to come.
