What was the reason for flushing the engine?
I asume this noise wasnt present before the flush was done?
Any oil warning lights come on after this was done or any other warning come up?
Where exactly does this noise seem to emit from?
there was no reason only my mate said buy him some flush on ebay then he didnt want it,so stupid me thought ill use it,the last oil change i done a flush with the small bottle you get from asda.i assume it does hert only helps ,now i no not to flush these engines .the noise seems top of the engine tappety and the oil warning lite comes onwen runnig
Ok..I never advise anyone to flush or supermarket flush of all things in an engine,especially at that mileage - sometimes that can wash away lubrication that builds up around the bearings which you dont want to do,and cause a whole load of problems internally..only time you would use such fluids is after a cross contamination fault with water and oil..any other time you shouldn't have to flush an engine, regular oil and filter changes does that..you can flush,run the engine with some cheap oil.thats normally the best way - then drain that out - replace your oil filter and then add your better stuff after which,so your you havent lost any of the lubrication that forms around the bearing/gaps... If your oil light is on then it means you may have Low Oil Pressure - i would of advised getting the oil pressure checked before you went straight in with the oil pump replacement..just to confirm really..but seeing as its off and another to be fitted then you have no option now but to fit it and hope for the best..one other thing i dont see you have mentioned.unless you have done it already..is the Oil Filter - has that been checked or replaced,it could be blocked...other than that..if that noise wasnt there before your flush.. could be due the oil pump or blockage elsewhere through the oil passages not allowing oil to reach up to the top end..or the vital lubriaction that forms around the bearings/lifters/gaps has been washed out..which means normally top end at fault..but try fitting the oil pump / change filter is not already done and see if that makes any differance..
that is the what i was going to do and what i thought that some blockage occured..forgot to mention at the time of running the engine there was no oil spitting from the head when i took the oil top up cap of.thats why i assume pump or blockage
Normally like i say it very rare for anyone to flush an engine out with any type of flush product..i do it very rarely myself unless its actually required because some of that flush residue left over in the passage - can actually be quite difficult to get rid of out the engine completely - you no doubt need to add a cheap oil and then run that thorugh upto to temp and drain off then add more again run that upto temp and drain off before adding the good stuff..but most often if the engine is oil /filter service routinely then you should never have to that.... You dont say what product of flush you used..id normally advise the range of engine flush that Forte does..bottle with a white top...and try that..but put the only thing you can do now is get the pump back on and fit everything back and try the cheap oil changes as suggest above if the new pump doesnt work out...
