What are the common problems in Ford Transit Custom engines?

I recently bought a Ford Transit Custom and I want to know what are the common problems I should watch out for with its engine. I'm not a car expert, so any advice will be greatly appreciated. Thanks.

One common problem with Ford Transit Custom engines is the timing chain becoming stretched or slipping, causing unreliable performance and potential engine damage. My advice is to have it checked regularly and replaced if necessary.

Another issue is with the coolant leaking into the cylinders, leading to white smoke coming from the exhaust and potential overheating. I recommend checking the coolant levels regularly and fixing any leaks promptly.
