Well after an initial running, I went for a twenty kilometer drive and was quite surprised by how sweet this motor is. It's very gutsy, responsive and amazingly quiet. At idle I could balance a pencil on it....Haven't taken it above 2500 RPM and possibly will never need to pass the 3000 RPM mark! No oil/coolant leaks yet and it looks like the stainless steel water pump inlet pipe I made might hold...why Kia/Rover ever considered plastic as a material for these parts is a mystery.
Thermo fan has decided to function correctly now too...cutting in when the temp gauge reaches just under the halfway mark. The air con is wonderul and the Clarion wireless sounds like the Royal Albert Hall. This Carnival is pure pleasure to drive, just hope it all hangs together... after a few hundred more kilometers I'll report back.
Think I'll buy another blown up 2.5L...now I know what's inside.
