Hi guys,

Let me introduce here, cause this is my first post. My name is Igor, I live in Dubai, and since I moved to UAE, I got very interested in offroading!


So we decided to buy a used Nissan Patrol, because they seem quite reliable cars, and they are very valued in this part of world.

I found a 1999 Nissan Patrol with 4.2L petrol engine, with carburetor, for a Ok price, since I said the used one are very, but very pricey here!!

So my first concern is:

- I couldn't found that this type of engine was ever installed in 1999 Y61 model. I found on Internet that only injection engines, and mostly 4.5L where instaled in that year (https://en.wikipedia.org/wiki/Nissan_TB_engine)? Is maybe this engine installed later in the car?

- Second problem is that engine, when is idle sounds like diesel? I read, again on the Internet that this could be a piston problem?

I apologize if my question sounds silly, but I am really not a mechanical guy ))

Kind regards, and thank you for your answers.
