PCV Valve Replacement

Energy from exploding fuel is what powers your engine, and some of the vapors from those explosions escape into the lower part of the engine, which is called the crankcase. These gases are made up of nearly 70 percent unburned fuel. If the gases are allowed to remain in the crankcase, they can quickly contaminate the oil and turn it into sludge. Sludge is one of the biggest enemies of your engine—and it eventually leads to engine failure. The pressure build up can also cause seals and gaskets to blow, which is why the gases need proper ventilation.

Gasoline engines used to include a hose that let the poisonous fumes vent out into the air. Since 1963, the federal government has required gas engines to have a special one-way valve installed to help reduce dangerous emissions.

The positive crankcase ventilation valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Clean air is pushed into the crankcase through a breather tube. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil, but the life of your engine too. The PCV relieves pressure in the crankcase, preventing oil leaks.

Eventually, your vehicle’s PCV valve will become gummed up. Once that happens, it can’t move enough air through the engine to keep it working efficiently. If the PCV valve is sticking enough, it will result in oil leaks, excess oil consumption, and a failing intake system. If you experience surging, hesitation, or leaking oil, it could mean that your PCV valve needs to be repaired.

Consult your owners’ manual for recommended PCV replacement intervals. Most manufacturers recommend having it replaced between 20 and 50 thousand miles. However, some manufacturers don’t list intervals for PCV replacement.

Usually, we can diagnose PCV system problems with a visual inspection. Fortunately, PCV valve replacement is both quick and inexpensive. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency.

If you have had your car for a while and this is the first you’ve ever heard of a PCV value, ask your tech to check yours out or call Loren’s Auto Repair at 406-755-7757.

Wheels To Thrive Information

Why We’re Doing It (Wheels To Thrive)

In 2011, Loren and Denise Sallee asked their son Travis to move back home and help out with the family auto repair business. Travis wanted to help and moved home with his wife Sandy and their daughter Cielo. Once he got home, he started seeking training and education opportunities within the industry so that he could continue his parents legacy and commitment to service with integrity. It was at one of those trainings early in 2011 where Travis got the opportunity to participate in a round table discussion with other shop owners from around the nation. One of the shop owners had the idea to give a car away. It made sense, after all we fix cars all day long for people and often we have the chance to come across a vehicle that simply needs too much work for the owner to justify, but where the car is still nice enough to fix and can be of service to someone else.

Travis and his parents talked about how they could go about giving away a car. Just giving the car to someone they knew didn’t seem right either. After you have been in this business for a while, you definitely start to learn that there are a lot of people who need cars. If we gave the car to one just person, we’d have to leave out everyone else we know who may need a car. Then the idea of giving back to our community came along. Loren and Denise have a long history of working with groups and charitable organizations within the valley and they know that there are many good people out in the community who are actively trying to make the world a better place and serve other people. Finding a deserving person that we could help by giving reliable transportation to seemed like the right fit and the right way to go about giving away a special prize like a new car.

It took a couple years to put the program together and in 2014 we were able to give our first car away. Now in 2017 we are able to give our second car away. This year our giveaway vehicle is a 2004 Ford Explorer Eddie Bauer Edition. We think that just about any of our typical customers would be proud to own and drive a vehicle just like this on a daily basis. The vehicle did need quite a bit of work to make it reliable again, but we did it. We fixed everything we could find on it. We even put brand new tires on it.

So as a family owned business, here we are, ready to give a away our second car. We are very proud to have this opportunity to give back to our community. We’re excited to find the right person and make a difference in their life. Giving back to our community is important to us and we hope that you will participate by spreading the word or nominating someone you know who is out there serving others.

Thank you,

Excellent service!! We are from Wisconsin and found Loren's on the web. They were able to fly in a new front axle and get us on the road in just 3 days at a very reasonable price. A quick follow up visit for adjustments allowed us to continue our vacation as planned. Absolutely recommend them. Mark was personable and knowledgeable, they offered a shuttle service and John was a great technician for our Xterra!!

This was the best car repair shop I have ever done business with. For being a young woman, who honestly doesn’t know a ton about cars, they were very thorough in explaining things and I trusted that they weren’t trying to rip me off based off my lack of knowledge or me being a young girl. Too many times have mechanics/car maintenance men try and rip me off. Once someone tried to charge me $180 for an oil change! Ridiculous. But not with these guys. They were awesome. My car broke down at a horrible time when I was busy with work and about to go on vacation. I had my car towed there and didn’t have time to stop by. They inspected it very soon after that, and got ahold of me. Then I was out of town for a couple weeks and they let me keep my car there. Even when I got back they had put it in the shop the night before so all the snow would melt. They were very friendly and even have a complimentary shuttle service when needed. I wish I could give the names of all the people who helped! Chad was awesome and answered all my questions and my dads when he called from a state away haha! The young girl who picked me up from the shuttle was super nice and has good people skills. If I ever have car problems again they will definitely be who I go to. Thanks guys!

Lorens never disappoints! They continually meet above my expectations. They met competitive rates, they have been upfront with charges and even gave me a loaner vehicle while doing their repairs. I will only ever use this shop. Mark at service desk is amazing and very knowledgeable!

I'm out here in West Glacier on vacation. During the trip, we hit a pothole and the exhaust started making a loud noise. We figured a hole had rusted open or something similar. We called Loren's Auto Repair to get it checked out, and they were awesome with recommendations. They let us explain the issue and then confirmed what we thought it was. They weren't able to get us in before we left, but they were kind enough to suggest a mechanic in town that possibly could squeeze us in. This conversation was a sign of trust and good business. The prices they quoted were fair and had excellent customer service. Thanks!
