Look. If you want to check if the PCV si giving you the headache, it is a simple test to do... PCV valve splitts into two rubber hoses going to the intake manifold. Unhook the PCV from the valve cover, (let the cover breathe) and use a bolt or something to plug the two rubber tuber so the...

I hate to have to tell you guys, but it's the rings... I had the problem, and it's the rings. The compression ones are fine, but the oil control rings are stuck... http://www.mazdas247.com/forum/showthread.php?123770462-Smoke-on-cold-start

Ok, so you have that nasty clunking sound it the front driver side suspension, tipically when going over small bumps, but you can not put your finger on it, coz the endlinks are new, bushings are fine, steering arms are good, no slack what so ever, but funny enough, when you turn the steering...

Hello there. Yes, there are more of us with the problem... Well, depends how much you love your car... If you plan to drive it / own it for a longer period of time, it can be rebullt to last... Yes, here in Europe it is harder to get some good aftermarket parts, but over in North america...

Bumping the thread back, with some good/bad news... Well, the good news is: I found the problem of cold start smoke. Bad news: Well, it's the rings... Worse news: The rings are fine, not worn out, not scored, not broken...So, what is it then? Ok, here's the details: Mazda's pistons are...

BUMP ing the thread... Anyone, any news? Bontrager? Mine now smokes on regular morning basis... If I don't startup and drive immediately after startup, I make one hell of a smoke screen...

Just bump-ing the topic to see if we have any news,,, on the smoking issue!!??

Hmmm, good point there... But my car smokes like crazy when cold, and even then, I don't have any excessive blow by, nor my oil consumption goes on the fritz... I haven't burned maybe 1mm of oil on the dipstick in the past 1000 km (approx 600 miles) Well, here's what I did a few days ago...

Did you do something about the smoking issue yet?

Regular...

Huh, I recently did the oil change, and, same thing happens to me as well. It smokes as smoke bomb... It is significant that the amount of smoke increases drastically immediately after every oil change, and reduces slowly, to a point where it almost doesn't smoke, but alas, the mileage forces...

Well, any news there???

Hello there bontrager_steel The exhaust valve stems are always under pressure and extremely high temperature due to the exhaust cycle (high overpressure impulses)... The intake valve stems are always under vacuum, because of the intake cycle, especially when engine is under high RPM but the...

Take a look at this thread, friend!!! http://www.mazdas247.com/forum/showthread.php?t=123770221 I had the same problem... Now I do not have as much smoke coming out on cold stars, only every other time, and just a small puff, like a puff of cigarette smoke... or so... Before the seals were...

Yes, but, even here if you purchase a non-abs protege (it is called 323 here) or one with weaker engine 1.6 liter or 1.3 liter, you'll get rear drums... (scratch)

Yes, the same reason you like drums so much is the one I dislike them!!!! When drums sit over rainy night, and a tiny layer of oxide creates on the drums, next morning it is enough to just barely touch the brake pedal for the rears to lock up... Not to mention I almost lost my head a couple of...

Well, not necessarily, I have 4 bolt/stud wheels and rear disks... It is weather the car has or has not the ABS system... that determines the drum/disk brakes on rear wheels... Drum brakes have an "auto boost" or "self boost" feature, meaning the brake pads have self leverage when brake is...
