Using Petrol/WD-40 to clean engine valves

Guys, i just want to ask you if it's possible to clean the engine valves, air intake valves and injectors by inserting little amount of petrolor kerosine oil(mitti ka tael) in the engine oil, intake vaccum, throttle body or should we use WD-40 in the same manner to clean the dirt and carban that sticks on lifters,valves,injectors etc ?

Which is better, petrol, or wd-40 because there are alot of things available in foreign markets like seafoam,BG,red... that you can use to clean these things. or if some expert knows What to use where, would really help.

Don't use WD-40 or kerosene oil, that's not what it's meant for.

The best way to clean injectors is to remove them and then clean them. Of course you'll have to take it to a professional to do that. Valves obviously require a different treatment, since they can't be removed without removing the head.

If you are looking for a quick fix, I would recommend Liqui Moly's Jet Clean. It is meant to clean Valves, and Injectors. What basically happens is that they disconnect the fuel line and connect it to the Jet Clean fluid and run your engine for about 40 minutes on the cleaning solution. after cleaning is complete they reconnect everything back together.

I've tried this treatment a couple of times. It increases the car's pick noticeably and improves mileage marginally. Do it every 30,000km to keep valves and injectors clean.

However I am in Lahore and don't know if there are any people in Karachi who deal in Liqui Moly products. May be some Karachi members can help.
