Just serviced the Firevan. Put 10w40 castrol get semi synthetic in it (it was on sale in Tesco) and fitted the correct EFL90 (well halfords equivalent) oil filter (it had a zetec EFL600 oil filter on it).
Now the engine once it warms up sounds really rattly, like piston slap or cam knock.
It's an ex German Fire van so has low mileage on it, and sounded fine before the oil change. I've checked the timing just in case it was that but that's made no difference.
I'm guessing the oil I've put in is too thin hence the noise.
I'm going to order an EFL600 filter and refit that as thats what i took off instead of the EFL90 I've fitted but what oil do people recommend for a Pinto?
Am I on the right track here or is it something else?
