I picked up 4 cans of this Subaru "Upper Engine Cleaner" today, cost me $80, going to give it a shot on our two dodgy cars, spray half the can in the inlet manifold vacuum hose while the car is at operating temperature but switched off, then let it sit for 5 minutes, then start the car and spray the other half in there while the car is running.

Should I also take the spark plugs out and spray it on top of the pistons or not with an aerosol like this, also how much would you suggest?

I just serviced the egg so I can't use it on that yet, maybe next service. During that service I did the oil, filter and plugs, all the plugs are burning grey/white which is good i think? But the 3rd spark plug, the ceramic was rusted/orange and the others were all fine?

Also a LOT of metal and sludge came out in the old oil and the lifters are very noisy, I have new ones but I just haven't been bothered to replace the old ones yet LOL.

Metal in the oil ? Not good!
