    Are you charging batteries on your DD?

    I swear I read somewhere that you shouldn't charge the battery if the ambient temperature is above 20C (heat kills). If true, perhaps this is why batteries go bad in the first place, it's quite warm under the hood? I have my onboard NOCO trickle charger (no temperature compensation) on timer to...

    Skyactiv Intake Valve Deposits - Photos

    Skyactiv engines have built-in catch can that drains back to the sump. EGR is managed by the valve timing, as indicated above.

    Does powder coating weaken an alloy wheel?

    I have bought four really old alloy wheels (2003) from Silverado to be used on my '14 Tahoe with winter tires. I had them sand-blasted and powder-coated, as they were in terrible shape. The shop had to do stripping and powder-coating twice, as they didn't like how they came out the first time. I...

    Mazda Skyactiv PCV System

    They essentially have a built-in catch can with integrated PCV valve. It is maintenance-free, as everything sepatated/condensed is draining back to the sump. It appears to be effective, however owners that install secondary aftermarket catch cans report amounts of oil caught. I bet that being...

    Catch Can on the Caravan (250km)

    Here's my setup. Just after draining the first (black) can after a cold spell. Quite nothing in the second, transparent can. This survived -22C. Gotta see what's going on on the clean side of CV system yet.

    Hope the picture shows properly. Here's how mine looks like. This time it's gotta be a charm for you!

    Catch Can on the Caravan (250km)

    I don't think that frozen settled water at the bottom of the can affects anything, at least not for a while. In the type of can that Stevie uses the input hose discharges from the top. The PCV flow hits the bottom, then goes up again and gets out of the can through the output hose, also at the...

    Some really nasty cold weather starts. YIKES!

    I'd be careful with charging the battery in-car in this cold. First, not every charger works normally at -20C, if at all. And it is not generally recommend to charge the battery at this temperature either. I have an on-board Noco charger under the hood of my Tahoe, and I disconnected it today...

    Catch Can on the Caravan (250km)

    I'm gonna air this question again. Why there is no concern about stock thin long plastic PCV tube freezing at the lowest temperature observed on this planet? Yet there is a seemingly definite possibility of thicker, larger internal diameter specialty rubber hose freeze at normal winter...

    Catch Can on the Caravan (250km)

    Stevie's results replicate my observations. I'm in Ontario, by the Lake (similar ambient temperatures). The stuff from the can never gets frozen. I have slightly different setup in my Tahoe, two sequential catch cans. First is similar to his, the second has a glass jar as the condensing device...

    Mazda SkyActiv FZ 71,210mi

    I'm posting this on behalf of Mazdas247 forum member. I thought this might be of the interest, as Mazda ATF UOAs are not widely represented here. The vehicle is CX-5 with 71,20mi at the time the sample was taken. This particular transaxle does not have an easy way to perform a complete fluid...

    DIY catch can material?

    Compressor air separators could be a good starting point. The filter would have to be taken out, replaced with a center tube, baffles, steel wool, etc. But the idea of a shell is sound. If only there was a larger one...
