Parts & Accessories Spare parts Engine, gearbox, and transfer case available. The engine has a ticking sound on the right side. The problem occurred after changing the spark plugs and the lifter malfunctioned. It needs a lifter for 250 SAR from scrapyards or new. The gearbox is very smooth, and the transfer case works perfectly. The engine oil is changed every 4,000 km. 4-speed. I just bought the engine, gearbox, and transfer case for 3500 SAR and want to sell them. The reason for selling is that I bought a 5.3 engine, gearbox, and transfer case for it. Please do not lowball.
