at which point you can build a forged motor if you wish If you get something like 170-185-130-175 then the 3rd cylinder is indeed shot and the rings need to be replaced. repeat for other 3 cylinders and write it downĬompression should be anywhere from 160-200 depending on miles (more miles = more wear = less compression) I did a test at 35k at sea level and had 185-190 across the board insert compression test kit into a cylinder, floor the gas, and crank the motor over until the needle stops moving up (friend comes in handy holding and looking at the gaugeĥ.
crack some beers and rip the IC off and plugs out as fast as possibleĤ. drive around for 20 minutes to ensure the engine gets fully up to tempģ. Invite a mechanically inclined friend overģ. go buy a compression test kit, its like 20 bucks or something, you can get it at any car parts store - Ģ. When you get the car back do the followingġ.
I drove the car straight to the dealer immediately after having that smoking episode (there was a LOT of smoke so I was quite concerned) and didn't have any more smoking during that drive (15 minutes or so). I only noticed the smoke after idling for 5-10 minutes and then subsequently for the next 15 seconds or so after driving away from that idle period. At this point it's not clear if the issue is actually due to the turbo or not. He is going to talk to Mazda Canada to see if he can still get them to replace the turbo under warranty. The service manager seems genuinely nice about the whole thing and has waived all the fee's they were going to charge me. What they actually did was run both a compression test and leak down test and both tests did show issues with the #3 cylinder. So they didn't open the engine as the advisor told me. I finally got some real information rather than the half-truths that the service 'advisor' was feeding me. I went back today and talked to the service manager. Thanks for all the support you're giving me.
Moderators? do we have a "how to" for turbo removal and re install for folks yet? The K04 is a simple rebuild for the most part for one who knows and has the tools. Seriously i hope you can find a good performance shop who will tell you what is really going on. If you find out it's is the turbo it's gonna be a lot less painful to rebuild then replace it. I do not know what it costs to have the labor of removing and reinstalling because i just handed them the turbo. And it was not that expensive and is like new or better. The good news may be that i just had one rebuilt by a diesel shop.
If you only smoke blue after idling with a hot motor it's prolly turbo. Please ask for test results that prove the motor is the culprit. There are a couple tests that they can do to figure this out, and probably worth the price as compared to motor replacement. Yes i suggest that you have another shop that you can go to and trust for a straight answer.
