Nissan navara 2.5 2009 59 plate

Description:

Just wanting to know what I could get for swaps on my navara

Had new engine fitted when I bought it
I purchased the engine from north West engine services and runs great

12 month mot just put on this week
And service as you need to service new engines 500 miles after fitted

It has a oil leak from the front crank seal
Runs perfectly fine until gets warm and looses power.

Soon as you pull over turn off then back on it runs fine again I have no idea why it's doing this

Looking to swap for something of the same size or estate car as I've just bought a caravan and dont want to risk towing it incase the car looses power while towing
