once I tried mobil 1  0-40.. lifters were happy and silent.. but no way for frequent changes with that expensive oil..   

[Marks DTM Calib]

With regard to the said hydraulic lifters, I have heard people say that once the oil is in from first start up it is almost impossible that this gets flushed when doing an oil change due to the hydrostatic properties keeping it in place. If this is true then that oil is the original 'first fill' oil. This then degrades and causes varnish deposits on the lifters (inside) stopping them from doing there job correctly, in which case they would then act as solid lifters. Can somebody with the appropriate skills, a 'subject matter expert' so to speak clarify this.
Absolute confirmation or denial with proof would be good.

You see if it's true, then no amount of 'lifter treatment' would be doing any good as it would not be getting into the 'hydraulic' parts of the lifters, if you see what I mean.

Something to ponder on boxing day, rather than watching repeats of James Bond or Bedknobs and Broomsticks or whatever.

Enjoy!!!

Mostly true, there is some small oil loss each time the lifter is compressed but, its not much.

However, the key thing is that any lifter with gummed valve seats (the lifters have a small ball bearing based one way valve) will be allowing plenty of oil in/out (hence why they are noisey).

So will the Wynns treatment remove the gummed deposits from there or will it be a case of taking them out, stripping them to clean properly then putting them back in as long as they are not worn?
