Piston Slap: A Rust-free Mazda for the Current Millenia?

Sajeev,

I recently bought a 2016 Mazda6 Touring. The salesman gave me a crazed look when I told him it absolutely had to have a six-speed manual transmission. But the dealer managed to find two manual Mazda6s within about 300 miles, one of which was 45 minutes away and painted in Deep Crystal Blue paint with the black interior I wanted. I’ve put about 400 miles on it and it’s a great looking, smooth shifting car; I’m very happy.

I expect to get flamed because it isn’t brown, diesel or a wagon, to which I respond in my best Sean Connery voice, “Suck it, Trebek!”

Piston Slap: Feelin' Rotten Sans Seam Sealer?

Hey Sajeev,

I enjoy reading your posts on TTAC. This one is a chassis related question and concerns rear quarter panel rust issues on old school Hondas.

I’ve got a 2000 Civic SiR and I’ve poked around the rear wheel wells to figure out why that may be. It seems that Honda didn’t seal the rear quarters well enough. There is no sealant present on the inner skin of the outer portion of wheel well. The outer skin just tends to ‘fold’ into the inner well and just ‘sit there’ as exposed metal.

Hi Sajeev,

Long-time lurker on a daily basis for over 5 years now. Not sure if this is a worthy question for Piston Slap but here we go: In about two weeks’ time I’ll make my final payment (0% loan ftw) on my 2008 Mazda3 GT 4-door (‘S Grand Touring’ in US spec) with just over 97,000 km. It has served me well with no at-cost repairs other than routine maintenance (some minor stuff was covered by warranty). I have been looking forward to payment-free living and would happily keep the car for many more years, but one thing has been rattling around in the back of my mind…

Piston Slap: Limited Use but Unlimited Potential?
TTAC commentator jdmcomp writes:

I own a Jaguar (Ford Era) that gets driven only about once a week, with jaunts of a few miles to several hundred. I keep syn oil in the engine. I have owned this car for several years and the only problem to date is the flat spotting of the tires. What should I do to keep this vehicle in good running condition? Is weekly driving enough?

Hello Sajeev,

My conundrum is as follows: I am a graduate student with another 1.5 years left of school. I commute at least 200-300 miles a week living in rural Maine (so a car is a must for me). My ride for the last 4 years has been a 2002 Mazda Protege5 with manual transmission. Bought in August 2007 with 69,000 miles, now at 143,000 miles. The car has never outright let me down and I love the balance between fuel efficiency, utility of the hatch, and fun to driver factor. What I don’t love is that it keeps rusting away. I have had minor rust repairs performed in the past to get it to keep passing inspections – the rear wheel wells, the floor beneath the rear seats. The rust around the windshield became bad enough that it started to let a little rain water in (though me and a tube of silicone quickly “cured” that). This car is by no means cosmetically perfect anymore, but it still drives great and has been kept up mechanically. Again, grad student – I feel like I am supposed to have a beat up looking car.
