Hi all.

seems the market is full of hydraulic lifters from all over the globe, had a chat with our American V8 spares importer here and was sold a set of "Sealed Power" hydraulic lifters, part number HT-817.

My question is are these ok for the Rover V8, dimensinally they look right but hydraulic lifters have different bleed down specs etc, I can get the Delphi ones as supplied by Britpart but they dont seem to last
Im also in 2 minds wether to change Cam at the same time but mine still looks good (pattern wise) Yeah Im aware of change as a set but that only applies if cam is being replaced, replacing lifters does not always require cam to be replaced but thats not the main reason for this topic, anyone use the above "Sealed Power" lifters......

Thanks

opppps, they're called sealed power, not power seal........

Not to worry seems its best to go the genuine route (Delphi) due to bleed down of lifters, ain that much more by about double the price

Crane or Eaton are good. Avoid Rhodes. Real Steel will be able to supply/advise you which to use. I generally avoid Britpart stuff where possible...

ALWAYS change cam and lifters together.
If not you'll be doing the job again within a few 1000Km's if that.

Thanks guys, as always Im open to advice even though I've doing doing engines for along long time.
Recent developments with oil is a problem what with the zinc being removed, this all started in 2004 on the quite
and none of the oil companies said a word anywhere.....one wonders why.
So Shell Helix is out and Shell Rimula is in, though not ideal if vehicle is fitted with a cat.

Our local American V8 guy called "RS performance" showed me some interesting litrature on cam failures and it all
points down to the fact that zinc has been removed from oils, he went on to say that there never used to be a problem
shoving in new lifters with old cam but he pointed out that now thats all changed.

So the word is: New Lifters, New Cam
New Cam, New lifters
And a oil zinc additive is a must when adding in new cams and lifters

Info for south Africans and possibly all if zinc is removed from the oil you use:
Here in South Africa I was advised to use Shell Rimula oil which is a 15W40 grade, it contains Zinc and is used extensively
in trucks and heavy plant for this reason.

And it doesnt end there, push rods ball ends wear differently so thats them tossed out, rockers..... well they need replacing
too as the end caps wear differently too.

Above link supplied by Selby P38 is a must read and thanks to you for adding it.

Isn't the Helix a semi-synthetic? Is that the difference between the 2 oils other than the Zinc?

Rich Hilex alone is a mineral based oil only,the Helix ultra and ultra plus are fully sin or syn blend.
The Rimula oil is a Diesel oil has some zinc in it.
Note that Shell Aust has just changed its range of oils Rimula is out maybe the zinc too would have to ask the Technicial guys. Note it was in a 4lt container, if all there other oils are the same they have lost me i can't stand reducing the quantity and charging the same to recoop marketing and design changes because i buy the 5lt container just enough for a oil change:naughty:
