Barely running 2006 Suzuki
VEHICLE: 2006 Suzuki Forenza 2.0L 194k miles
COMPLAINT: While driving, a loud noise was heard and the vehicle died and would not restart.
The vehicle owner called us to ask if we worked on Suzuki cars, I said sure and she said she would have it towed to us. After a bit of time passed while awaiting the tow truck, she tried to start it again, it started but barely ran, she called to give us this additional information and to tell us it was on its way.
Once the vehicle arrived and I got a bay open, I went to try to start the vehicle and maybe not have to push it in. When I first tried to start it, it cranked but definitely did not sound good or start, I thought... oh well, the damage is already done, so I tried a clear flood type attempt to start it, the engine started, barely ran at best... I drove it into the bay directly across the little street beside the building and parking spots.
I’m not sure why, (habit I suppose) connected a scan tool to retrieve any codes, then a quick underhood visual inspection, almost immediately, I noticed the shielding wire for the ckp sensor, next, I went in cylinder....this engine had jumped time, I wasn’t sure if anyone had a known good cmp/ckp waveform and if the owner approved this repair, I wanted to ha be a known good and the current bad waveform too.
The repair was approved,, on teardown, the reason for the loud noise and stalling was easily seen, the idler pulley bearing had come apart and thus the jumped cam timing.
When it jumped time did it bend a valve or 2 that would also cause bad idle . Or ran a valve into a piston,might also due a cylinder leak test to check that out .
No sir, only the poor running from jumping time
Great find Rusty .. love the before and after a always scoping to make are skills better and better
Wow! Never even HEARD of a failed idler like that before. Thanks for posting.
You’re welcome! Thanks sir!
Really? I see them all the time on various vehicles.
Must be the weather. I've seen the tensioner that goes "tap-tap-tap" on the Honda 3.5L, a few times, but no failed bearings, like he showed.
Could be the vehicle mileage as well. I often see vehicles very poorly maintained with well over 100K.
That's every car here. Usually on its fourth owner. "Recommend disposal" is my go-to summary of my inspections. :-)
Good job Rusty.
I didn't know here were any Suzukis left in the heartland. It also shows maintenance intervals are written for a reason. Great captures, and before and after, thanks Rusty
