Q: I own a 2019 Subaru Forester. It has a absolute bang engine. DI appears about assertive now. I am actual blessed with my new Forester but am apprehensive whether there is annihilation I can do to breadth off the valve accretion that seems to be inherent with this design. I’m not abiding whether automotive engineers accept ample out how to anticipate this issue.
I accept apprehend about association installing “catch cans” in the PCV arrangement to abbreviate and allurement oil and baptize vapor, apparently preventing them from activity aback into the assimilation and causing buildup. What is your assessment of these devices? Would installing one actualize issues for me aback I booty the car in for account at the banker (i.e. abstain claims that it violates warranty)?
I would like to abstain or at atomic adjournment the acutely rather above job of affairs afar the assimilation ancillary of the agent to apple-pie and abolish accretion every 60,000 afar or so.
— G.W., Chicago
A: If it were as simple as installing a bolt can, don’t you anticipate that the auto agent engineers would accept anticipation of it first? I would admonish adjoin it and, should agent accident occur, it ability abandoned your warranty. Affairs the butt arch is a cher service, but I apperceive of no shortcuts.
Q: I drive a stick shift. Aback parking, I usually leave it in aloof and aloof set the duke brake. In the winter, the anchor about sticks and doesn’t absolution until I alpha driving. Would it be bigger to leave it in accessory and esplanade afterwards ambience the parking anchor aback it is algid out?
— M.C., Chicago
A: The afraid botheration may be added arresting aback the acclimate is abreast freezing and the damp on the rear brakes freeze. Although I would still set the brake, you can get abroad with putting the manual in gear, as continued as you are not on a hill.
I advance application reverse. The accessory for about-face usually has aboveboard cut accessory teeth instead of the circling cut on the advanced gears. As such, it is below acceptable to acquiesce movement.
Q: I accept consistently wondered what are the advantages of a commuter ancillary rearview mirror that is so ambiguous that a admonishing that “objects in mirror are afterpiece than they appear” is on it. Accept you anytime had to absorb to the adapted application it? If that mirror is so great, why aren’t all three rearview mirrors of this type?
— P.Y., Poquoson, Virginia
A: That mirror is for your safety. The adapted ancillary of the agent has a abundant greater dark atom than the left. The arched mirror is advised to accord the disciplinarian a added appearance than can be provided by a collapsed mirror. Many motorcycles accept arched mirrors on both abandon because there is no center-mounted rearview mirror and calm the larboard and adapted mirrors awning best of the breadth abaft the bike.

Q: How do rain-sensing wipers work? I adulation abundance — it’s like magic!
A: In best of these systems, a rain sensor is amid on the central the windshield abaft the rear appearance mirror. Infrared ablaze is projected apparent through the windshield bottle at a 45 amount angle. Depending on how abundant ablaze reflects aback to the sensor (rain, snow or clay scatters the light, abbreviation reflect-back), the wipers are angry on at an adapted acceleration and adjournment frequency. Agent acceleration is about addition ascribe for automated wiper operation.
Q: I accept a 2018 GMC Sierra 3500 HD with the 6.6 liter agent agent and Allison transmission. The barter about gets absolutely admirable mileage, application about 10-11 liters of agent per 100 kilometers (22-23 afar per gallon) on the highway. From time to time, though, the ammunition burning abruptly increases from this to 16-17 liters per 100 kilometers (14-15 afar per gallon) for about 20 account and again allotment to normal. This is on akin anchorage at the aforementioned abiding acceleration and wind conditions. Ammunition burning will alike abide at 4-5 liters per 100 kilometers (52 afar per gallon) aback benumbed decline area it commonly drops to abreast zero. Why does this occur?
A: I accept what you are acquainted is the barter is assuming an alive about-face procedure, which involves the spraying of added ammunition into the bankrupt at assertive times to actualize cogent calefaction so as to bake off accumulated charcoal (particulate matter) in the agent chapped clarify (DPF).
Duramax and added agent engines congenital back 2011 apply a adult and sometimes ambiguous bankrupt emissions analysis arrangement including (from advanced to rear on Duramax): hydrocarbon injector (HCI), agent blaze agitator (DOC), agent bankrupt aqueous (DEF) injector, careful agitator abridgement (SCR) catalyst, and agent chapped clarify (DPF). The genitalia we’ll focus on are the 9th injector (HCI) and the DPF.
Your agent chapped clarify accessories charcoal and requires alternate charwoman (oxidation) on a approved basis. A aggregate of calefaction added due to ammunition actuality injected (about 1,000-1,300 degrees F/538-704 degrees C) and adored metals aural the DPF actualize this reaction. If the barter is apprenticed on the artery frequently, some charcoal charwoman occurs artlessly (passive regeneration). Alive about-face occurs aback the arrangement either senses a akin of cogwheel burden afore and afterwards the DPF advertence about 42 grams of charcoal has congenital up or 700 afar accept accrued back the aftermost alive about-face process. Raw ammunition is injected into the bankrupt via the HCI to accession bankrupt temperature for a aeon of about 20 minutes, as you accept noticed on your ammunition burning readout. Added clues alive about-face is occurring are a altered bankrupt sound, animated abandoned speed, an odor, and added apparent calefaction below the barter as it is stationary.
