Services Performed
- 4 faults stored o/a – engine did long crank prior to pulling in shop. Checked for engine oil level or oil leaks, no leaks visible, oil at full mark. Cleared faults and started engine, no faults returned. Check crank position sensor reading and ran through checks for camshaft timing solenoids and timing adjustment while running/driving. All checked OK at this time. Previous shop replaced cam adjuster solenoids and we can find no issue with crank sensor at this time. Performed many starts on vehicle and it never did a long crank symptom or had any faults. We let vehicle sit over night 2 nights and checked cold start in the AM as well as start the engine several times through the day, with test drives – no cel or faults stored. Drained engine oil and took oil sample, refilled with fresh oil and set level to full mark. Fine metal debris still visible in oil – same as last 2 changes. Performed test drive and scanned for faults again – no faults stored, engine is running well at this time. We suspect an oil supply issue to the timing components during cold start/initial start, intermittently which is causing timing faults and extended crank symptom. Based on fine metal debris in oil on last 3 oil changes, suspect internal engine damage from driving vehicle with failed cam adjuster and oil control valve (we fixed last visit) and have verified the repairs 2x and find no issues at this time other than the CEL returning after the customer picks up the vehicle. We cannot replicate the symptom after several attempts to re-create and diagnose.
