I have another question. I want to wash engine of Pajero Mini 1995 I recently bought, the previous owner didn't maintained it well. The engine is pretty dusty especially the area where gearbox and engine are coupled and I think the distributor above it too.
I got the car serviced as soon as I got hold of it, but the service station didn't put any jet water on engine, just a little bit on the grill and radiator area. He told me these cars have too many sensors, so they avoid putting water on engine so there's no issue when starting after service.
What I'm planning to do is, get engine sprayed on with Kerosine oil, leave it for 10 mins, then wash again with Kerosine oil, or maybe jet water. Do you think it's a good idea?
Of course I've read the advice to not put water on hot engine, let it cool down for about 30 mins before doing something like that. So I'll be careful about it for sure.
