Had noisy tapets for about a year, and was going to get them redone with the help of a remortgage, but Jeff at Zedworld said try the noisy tappet additve from harry halford.

 

well bless my soul if it didnt just do the trick, not straight away though.

Put the whole bottle in and after a couple weeks, ( dont use that often now ) noise gone!! quiet as a mouse.

 

Worth trying if you have the same problem.

I did it just afte an oil change, so may have to add again on next change but so far so good. :hyper:

I thought engine additives were a big nono :nono:

i have heard people say this myself ( but then some say they are fine), whats the reason for not using additives?

so will this solve my lazy lifter issue and stop me sounding like a sewing machine?

or you can try another oil i used have same problem changed from 10/40 to 5/40 millers fully synthetic , now engine is very smooth.unless you havnt started car for a while which can result in tappet noise until car warms up.

Ditto, I switched from castrol rs10/60 to valvoline 5/50 fully syn, cured my rattles.

surely if jeff says its ok it must be ok :D

dont know which oil the guys at ZTech used but my engine was so quiet after the 60 k service that i tried to start it again when it was running .....i can still see the horrified faces of the lads down there as i engaged the starter into a spinning lightened balanced flywheel

Some people use a cup or two of power steering/auto box fluid - it has a detergent property that can cure the lifter noise. But really - changing the oil first is a good idea. Only resort to additives as a last gasp fix before changing parts is needed!

Another alternative is to run it with a good quality diesel engine oil for a few weeks as these have better detergent qualities and dirt holding qualities.
