Viggen motor ticking - sludge or not sludge?
Hey all,
First post after lots of reading and learning from other posts. Thank you in advance for any insights you may have.
- I changed the oil and filter in my 1999 Viggen (105K miles).
- Left it at the airport for 3 weeks.
- Drove 5 mins home and noticed that the turbo and motor felt "laggy". It was boosting but something just felt wrong.
- Took it for a drive with wifey (3 miles) while watching a plug-in computer reader on my phone (Dash Command). No error codes, no reported issues.
- Got home and I could hear a ticking from the motor.
- Did all of the research, worried about sludge.
- Listened to motor with a wrench to my ear and the noise was certainly coming from cylinder 4, opposite end of the timing chain. Quiet on the 1st 3 pistons, and then clackety-clackety on the 4th.
- Decided to do a motor flush with "Motor Medic" for 5 minutes, drained and changed the oil with new and new filter....same ticking.
- Crap.
- Took the valve cover off, expecting sludge, didn't see any. Golden color, no nastiness. (see photos attached).
- Removed the spark plug from 4 and found a pretty damaged spark plug. Ceramic missing, spark end corroded, etc. The other 3 plugs look fine.
Is my problem just a bad plug? Can I just change the set and be good? If the plug broke and parts fell down into the cylinder head are they still there rattling around? What should my next steps be?
Thanks all,
John
