Got this ride from Saudi embassy last year in June, it was owned by an embassy employ and was driven just around 73000KM.
The problem was there even before i got the ride, however, it didn't effect the performance much back then and not even now but i can't stand it.
I am pretty sure the engine must have been washed when hot as many people like me don't have much idea what harm it could do. I remember my self washing it when hot back in June this year.
And by my experience of last 1 year I think I'll have to establish a small workshop at my home for engine maintenance and repair as most of the local mechanics don't know what they are doing except replacing things and can't guide you in the proper direction.
The problem is, i don't know what tool and other equipment I'll require, may be you can help me a bit.
