Hydraulic lifters - help please!
Discussion
As standard they would have been fitted with standard RR lifters, but 'high rev' lifters are available and often fitted when the cam is replaced. You can also get Rhoads lifters which give you varying cam timing at different revs, but these are rarely used and if you have them you'll have noticed the loud clattering noise they produce at idle.

Yes,they sound bloody awful
i could never recommend the use Rhoads lifters even in Chevy or Ford V8,s,almost annoying as cam gear drive sets
That would explain my noise then! I have had the cam replaced and they put in Rhoads lifters. I hate the noise though. What would you recommend instead. It has a standard cam so not looking for anything specific, just better than the RR ones but not as noisy as the Rhoads!

The stock RR ones are as good as it gets,why have you Rhoads lifters on a stock cam grind?thing is your not going to be able to just slip in a new set of lifters on your existing cam
well not unless you want fairly rapid failure of both.
Thanks for the reply. When I had the cam replaced the garage that completed the work automatically fitted Rhoads lifters when the replaced the cam as they believe they are better. well not unless you want fairly rapid failure of both.I understand that I cannot just put a new set of lifters in now as they have worn in together. I was asking out of interest and in the event that if it needs doing again that I make sure I don't have the rhoads lifters fitted again.
I don't think I can do anything about it now, especially as money is a bit tight!

Ads,i would just put up with it till funds are there,as i said theirs nothing wrong with stock LR lifters
try buying some ear plugs in the meantime 
Thanks, trouble is I hate noisy engines! oh well at least I know there is nothing wrong with it.try buying some ear plugs in the meantime Maybe I should get a de-cat!
Thanks for your help.
hi, ive been through all this . its not the lifters..i have piper lifters in mine and the noise is worse when the engine is on load .ive been told by v8d that there is wear in the ports caused by high mileage,not warming the engine up or bad oil .i dont think anything can be done about it unless you have a new block
Well mine only has 25k and I bought it with 7k on the clock, so I hope not!
The original cam went because the pre-load waasn't set correctly when the engine was built leading to premature cam wear.
Hopefully the noise I can hear which seems to get worse when the car gets up to temperature on a hot day is just the rhoads lifters.

Dont panic Ads,my car as gone round the clock with none of this so called tappet/lifter bore wear problem thats been mentioned The original cam went because the pre-load waasn't set correctly when the engine was built leading to premature cam wear.

and the motors original,the only way these would wear that rapidly is if you had heavily contaminated oil going thru the motor for long periods,and if thats the case it would not just end with worn lifter boresEdited by That Daddy on Friday 23 May 13:17

I think its just the Rhoads tappet noise I can hear, I'm just very sensitive when it comes to noises!
Never known anyone to be happy with em,still its only the noise your putting up with,its not doing any damage;)I think its just the Rhoads tappet noise I can hear, I'm just very sensitive when it comes to noises!
