M40B18 heating

[apsaires]

Hi,

Well I've done a few works on my E30.... New head gasket, new houses (fuel, air and vacuum), new Walter Pump, new thermostat, new viscous coupling, new Sparks plug wires, new soark plugs, and I've changed the injectors (which has a little less debit)

Now the engine heats up a little... What do you think can be the problem?

Thanks

Sometimes the thermostats are just dud. If it is slowly over heating I would say thermostat

Need more info on the nature of the over heating really
