Dyno test

My Mazda got tested on a dyno. I'm proud to announce that the measured power (92,3 hp) was even slightly higher than the manufacturer's data (90 hp). And that after 17 years and over 125,000 miles! Now who would prefer a new engine that can't even last that long?

Here's a video footage:

Rubber exhaust mounts replacement

My Mazda had been making annoying noises for a month until I finally figured out what the problem was - the exhaust mounts/hangers. After I've replaced them, Mazda is wonderfully quiet and I enjoy driving it again!

I must admit, it's been a real struggle to install the new mounts. The task seemed easy, but it turned out to be very exhausting.

I replaced the three rear mounts on my parking place and the two front mounts in the inspection pit. I've found the first option easier since I could help myself by holding the exhaust with my foot while installing the mounts.

Front MacPherson struts overhaul

I've overhauled the front MacPherson struts. My Mazda has now new springs, upper mountings, thrust bearings, bound stoppers and dust covers. It was a little tricky to compress the spring - it has only four coils and it turned out to be impossible to compress the spring enough while it was attached to the spring only. Fortunately, attaching one end of the spring compressor to the strout solved the problem.

Control arm replacement

I had to replace the left front control arm, since there was play on the balljoint and the rear bushing was worn.

Luckily I've managed to do this on my parking place without a pit. The only trouble I had was with the stabilizer link - I couldn't remove it, but I've heard it's a common problem. I used a rotary tool to remove it and bought a new link.

Mazda running on synthetic oil now

Two weeks ago, I've cleaned my engine with an engine flush and poured syntethic oil (5W30) into it. Mazda is running much better now. Most importantly, it stopped emitting white smoke from the exhaust! I'm really glad I've changed the oil although most people would advise against it. They always say that you don't pour synthetic oil into an old engine and that you never change for "better" oil. This whole thing is more complex though.

This is how it looked like on 10W40:

Compression check

I've checked the engine compression in my 17-year old Mazda 626 1.8 - it was very good! 200, 185, 200 and 200 psi. I guess it's true what they say about the good old Japanese cars.

I've checked it because I was worried about the white smoke coming from my exhaust. Now I think it might be due to the recent oil change. My Mazda is running on 10W40 now. The oil type recommended in the service manual is 5w30. I will soon change the oil again and see if it helps.

PS. Here is my "how-to" video made during the cylinder compression test https://www.youtube.com/watch?v=1xnoOHZfhco

Ignition switch Mazda 626

Shortly after buying my Mazda 626, I've experienced occasional troubles starting it. The car just won't react and suddenly, after a few tries, it would eventually start. Whenever it didn't want to start, I couldn't hear anything (not even a relay), which indicated that something was wrong with the ignition switch. I removed it and checked it with my multimeter, but it seemed fine and it didn't look used or broken. Nevertheless, I couldn't think of anything else causing such troubles and I really don't like it when my car experiences starting troubles, and the new ignition switch was quite cheap (around 25 dollars), so I've replaced it and it has solved the problem for good.

Mitsubishi Lancer Evolution VI

Lately I've had a chance to take a ride (as a passenger) in a Mitsubishi Lancer Evolution VI Tommi Mäkinen Edition.

I've never taken any interest in race cars before. My friend showed me how this car accelerates and makes u-turn drifts. The adrenaline kick was amazing. The car was very loud when I was standing outside of it, but in the inside it was quite quiet.

Here is the heart of this car:

Sooo many switches:
