hi i bought an engine and put it in from SSS automotive and i didnt know u should put ur old injectors in the new engine or get the new 1's cleaned since they would have stuff dried out in them. nehow i was told the old petrol has dried up and now since they have had new fuel in them the old stuff went sticky and blocked them

neways i got a dyno and they told me my injectors are playing up and need cleaning...

so i was thinking im taking the head of my car tomorrow and i wanted to know is there some way i can clean my injectors when i take them out at home,

cause it would save alot of money??

are you sure of this? i mean engines and injectors run for many 100,000kms without any cleaning or changing etc and they work fine

oh i forgot to say when i had it dyno'd they took out my fuel filter, it must have been that old the filter broke off its casing and all the stuff in it must have went through into the injectors

Yeah cleaning injectors is no problem if you have your own ultrasonic cleaner, maybe a jeweler could do it cheap their their ultrasonic cleaner, done by pros who does fuel injectors your looking at about 20-40 per injector cleaned.

Show me a 'pro' that uses an immersion ultrasonic cleaner to 'clean' fuel injectors and I'll show you a 'pro' to run a mile from. Using that type of cleaner WILL result in damage to the injector pintle valve (it's a type of wear damage and the technical term is false brinelling)

A 'pro' that knows what he is doing will use a dedicated injector cleaning bench in which a special cleaning fluid is passed through the injector as it is cycled using a dedicated controller (ie very similar to the job the engine ECU does). At no time is the injector body immersed in the fluid.

      If doing that ^, I'd take the idle up valve out and plug the hole in the pump.

      You can try capping the power steering idle up valve at both ends if it's old. The valve and the intake manifold. That is something that is known to fail in Toyotas with age and it will suck power steering fluid into the intake and burn it in the engine which can cause issues. Then bleed it again with engine off first. Do like 30+ lock to lock turns with the front wheels off the ground.

      Update:   smoke test all pipes no issues cleaned reservoir   fluid put in ( dexron 3 atf)   steering turn side to side and could hearing  gurgling from steering rack which I assumed was air lock, opened one of the steering rack connections and could see loads of air getting pushed out( not sure if you meant to do that / whether it will re introduce air into system)   anyways, loads of side to side sound was gone. Turned car on, pump was slightly ( barely) wining so turned side to side few more turns and fluid level when car on was almost none in resorvoir which I guess is normal if car is one. Turned car of and fluid was gushing out. Almost 200-300cc was pushed out. Repeated engine off side to side followed  by engine on and same result       going mad now. It seems system is either sucking air in whilst on or there is tons of air which I am not giving it enough time to bleed. Thoughts?   would it work like brake caliper if I open steering rack copper pipes and let gravity pull all air out?   or maybe have a restriction somewhere? What is the red circled item, could that be blocked? It i
