Symptoms
Sluggish response, smoke and DPF trouble. Unsealed 4X4 has seen diesel intake runners choked down to a hole the size of a 5-cent coin, and says the 2.8's EGR cooler likes to leak.
The fix, step by step
- Remove and clean the intake and EGR valve every 50,000–100,000 km or so, as Unsealed 4X4 suggests, and check the EGR cooler for coolant leaks while it's apart.
- Replace gaskets rather than reusing them.
Tools & part numbers
- Basic metric tools
- carbon cleaner and scrapers
- new intake and EGR gaskets
