    Mazda5 Undercarriage condition - Your opinion on the rust?

    Its hard to tell from pictures at the front there, but I don't see any obvious holes, there's still a bit of painted surface on the subframes, and the pinch welds running along the sides are straight, so I'd suspect its mostly surface rust. This will give you an issue with all the small 6mm...

    Mazda5 rattling like noise from the front right

    Yes to all of those. Suspension noise can be tough to track down, but I've found that if I'm going in to the front suspension on an FWD car, it's always easiest to just try to replace everything short of the springs & struts if they're in good shape. Strut top bearings, LCA's, tie rod ends, sway...

    Lower control arm bolt stuck

    New control arms likely will mean that the car needs an alignment - this could explain the pulling and vibrations

    Mazda5 wheel swap question

    Yes, I put 17" wheels from a contemporary Mazda6 on my 5, they're slightly wider at 7" vs 6.5 but the offset mostly accounts for this. Tires wider than 205 on the 7" wheels may rub on one of the inner wheel well plastics slightly when the steering wheel is fully turned - this happened with the...

    What have you done to your Mazda5 today?

    Yes, the main purpose is for a bike hitch or rear carrying tray - I don't plan on much towing but having a hook-up for lights will be nice since bikes or cargo in the tray may block the normal taillights. With that being said, I towed a small enclosed U-haul moving trailer about 1000 miles...

    What have you done to your Mazda5 today?

    I recently picked up, cleaned, painted, and got new tires onto some old 17" Mazda6 wheels, and I think they look great! Also got a roof rack and tow hitch installed, and need to get around to the trailer wiring harness one of these days.

    Any cheap and reliable hatch bike rack for 2015 Mazda5?

    The biggest problems with the style of bike rack that just use straps to hold on to the rear hatch are that they can dent the rear hatch around the license plate where the bottom presses, scratch or scuff the paint with the pads pressed against the hatch or the hooks, and make it...

    Worried about piston rings...

    I may go down that route at some point too - in this case I was looking for panels that would make noise if I shook or hit them, and applied foam weather-stripping or felt-tape to the back to deaden the vibrations. The main culprits were the cowl panel around the wipers, the rear part of the...

    Worried about piston rings...

    At the time of the last compression pressure test a week ago, there still was positive pressure in the crankcase trying to lift up the oil fill cap. After another week, and the oil smell does not seem to be coming back. Additionally, unscrewing the oil cap and trying to pull it out while the...

    Worried about piston rings...

    Well, after all that, some sea-foaming, interior cleaning, and repeated aggressive driving once it's warmed up, the oil smell seems to be going away and not returning. Compression seems to have increased by about 5 psi across the board when warm, so that's a start, but I haven't been able to do...

    Worried about piston rings...

    Yea, that's my assessment now too... no harm in trying some more aggressive cleaners now, and driving it like I stole it. After doing some errands today, it definitely still smells of oil especially when everything's nice and hot like coming off the highway. I'll keep looking for external leaks...

    Worried about piston rings...

    Well, everything's back together now - new PCV, thermostat, coils, intake & cabin air filters, fresh oil and coolant, and things seem about the same. I can't tell about the oil smell yet since I basically fogged the neighborhood out on first start-up with all the oil poured into the cylinders...

    Worried about piston rings...

    I haven't used MMO specifically for cleaning in this way, but there are a bunch of people online that seem to swear by it, and it was less aggressive than pouring acetone, PB blaster etc (a few other of the suggestions I ran across) down there! It does not seem to be fully draining into the pan...

    Worried about piston rings...

    I've seen piston rings get carbon'ed up so that they can't rotate and don't seal well all the way around the bore, or don't wear in an even pattern over a long period of time. This typically happens with a lot of very low-load running, idling, cold-starts etc that don't allow the oil and coolant...

    Worried about piston rings...

    Got the intake manifold off today - lots of fiddly plastic clips for wiring and such that got accidentally broken, but zip ties will hold everything in place on reassembly. However, the PCV looked perfectly fine, and was still functioning as a one-way valve when I sucked and blew into it... so...

    Worried about piston rings...

    Digging into how to remove the intake manifold now - I've got a thermostat on the way, is there anything else that should be replaced while I'm there?

    Worried about piston rings...

    Well, compression when warm is 150-155 psi, so a little bit higher than when cold. There is still a pretty strong oily smell in the van when driving that dissipates when its off with windows & doors open. I think I smell a little bit of oil in the exhaust when idling too, which does not bode well.

    Worried about piston rings...

    Well, all the plugs looked good - no thick deposits or anything and a nice tanish-reddish color on the ceramic. Dry compression readings were 142, 142, 146 and 148 on a cold engine, I'll have to re-test after warming it up but for the moment I'm not too worried there. Phew! Next it's time to...

    Worried about piston rings...

    I was planning on doing a compression test later today and inspecting the plugs, and possibly going digging for the PCV. What compression should I be looking for? My 2012 van has the 2.5L L5-VE, but all the service manuals that I can find are for earlier model years with either the 2.3 L3 or...

    Worried about piston rings...

    I bought a 2012 Mazda5 a couple weeks ago (minimal rust, 108k miles, manual trans), and flew a few states away to buy it (not that many manuals available!). Everything seemed to be fine on the drive back to the dealership in the car, but I also had my face mask on when sharing the car with the...
