My 308 and also the 253 had tapped noise even after rebuild both. Ok it wasn’t very loud tapping but was able to hear when starting the engine when cold but after the oil got circulating the tapping noise was just noticeable. I just went for thicker viscosity oil and also just filled the oil just over full mark that did the trick. If the noise is loud then most likely a lifter has collapsed. Are you running Gas and petrol?

i was running hpr50 but nowe i have changed to hpr30. yesterday i changed the lifters with anti pump up lifters and the noise has stopped . when i took the old liffters out i noticed that three of them had collapsed. im only running petrol. thanks for you help

well i think i spoke to quick the problem has come back again the noise did go but i noticed that there was water in the oil after i changed the liffters so i did another oil change and now the noise is back can anyone help please

Maybe you've caused one of the new ones to collapse by running it with water in the oil? If it disappeared when the new lifters went in, thats the problem. Are you sure its the same noise though?

[ovh333]

im about 99% sure it is the same noise . is it possible to change just a couple of liffters insted off all of then seen they are new and only been in there for 6 days ?????

[SirHSV]

Im 99% sure if they are new then its something else are you sure fitting was done properly???

[ovh333]

yeah im sure they were done right i was there when they were done as i said the car was running great then i noticed the water in the oil so i changed the filter and oil then the next day the noise was back.
