Hello from Stockport

Hello and welcome to the site :)

As long as the engine oil is changed every 10,000 miles they are a good strong engine, higher mileage engines will probably need the timing chain kits replaced
Hello and welcome.
Like Vocky says, so longs as the oil and filter is done regular (I'd say every 5000 miles) they are a good strong engine.
