You have not been doing regular oil change to that car, maybe topping it off and there was sign of over heat in the engine.
Compare your engine to this engine

and this engine
https://www.nairaland.com/852138/how#10373320

those build up can also result from using wrong grade of oil with no detergent in them.

Here could be a lesson why buying the right oil saves money when compared to the cheap oils

like they said earlier there is no cheap fix for this just get a replacement engine.

A repair will be a new block, crankshaft, rods, pistons, bearings, seals, rings and an expert. then you have to know the heads will still work.

Remember the mechanic will tell you he can rebuild it, he will get paid for a job you will still end up with a bad motor, so only consider an advice that will result in a good engine and it is not necessarily the cheapest option.

Siena:
20W-50 oil is way too thick and heavy for any multivalve engine built after 1998. Just because Nissan actually stock 20W-50 oil, in Nissan-branded cans does NOT mean it's suitable for you truck.

Here is a copy of your owners manual, in section 9 , 5 W30 is preferred but 10w30 and 10w40 can be used in Nigeria 20w50 will not lubricate properly because it is too heavy

nurey:


Walk into any of this fueling stations and ask for their synthetic blend which will have stamped on it the recommended oil weight
Mobil
Total
MRS
Forte oil

Those are the ones I know and have seen their full synthetic oil.
