1. Why is my Isuzu 4JB1 engine blowing blue smoke after a cold start?
Blue smoke often indicates oil burning. In the 4JB1 engine, this is frequently caused by worn piston rings or a damaged 8-94391-696-0 piston skirt allowing oil into the combustion chamber. We recommend a full cylinder inspection to prevent further block damage.
2. How to identify if the 8943916960 piston needs replacement?
Look for scuffing on the piston side walls or carbon buildup in the ring grooves. If the piston-to-wall clearance exceeds 0.15mm, a replacement is mandatory to restore engine compression and fuel efficiency.
