Yes from under-neath though and not the actually bore walls??

yes it will lubricate the bore walls otherwise the thing would overheat and seize in no time. However most is stopped from collecting at the top of the piston by the rings

all of it hopefully, they don’t call it an oil control ring for nothing! it generally gets drawn up the bores by vacuum, but you do get a little splash lubrication too but either way the bores will be coated all the time or it will seize quickly! and yep wrong oil will kill nikkasil liners real fast, they need a certain chemical composition to avoid galling of the piston and hence liner death

Bore walls need a film of oil for lubrication and for helping the rings seal. Borewash kills your engine by removing this film causing the effect mentioned above where the pistons eat the walls.
In smaller scale problem terms, Mondeos are notorious for their cold start injector doing this if only started to move the car up the drive etc and its not uncommon to have to fire some 3-in-1 down the plug holes to help compression to get it restarted.t

Ah right cool.Cheers for that info guys.Never knew that.
Infact,last time i asked on here about oil recommendations for my old Puma VCT,i was told 10w40 etc will be fine and the Ford recommended stuff isn't necessary.

As long as its a semi synthetic 10w40 it would be fine for a zetec engine as its over spec at ACEA A3/B3. It wouldn't offer as good cold start protection though. (10w)
5w30 and 10w40 semis are usually the same price so no gain there either.

im no massive expert but adam are you aware of how temperamental nikkasil linings are? you cant even use fuel additives with them, iv seen pictures where peoples nikkasil linings have been basically crumbled away, then thats knackered engine for you
lee said they are sensitive too

Steve doesn't seem to completely know what he is on about. No offence intended.
You would be searching for a long time to find some semi synthetic oil that would completely fuck up any of Fords engines apart from the brand new stuff.
They will be sensitive to mineral based oils, but you would have to be a complete moron to make that mistake.

Why did Ford/Yamaha produce the engine with Nikasil liners anyway after all the hassle BMW went through when they done the same with the M52 etc??
Don't other manufacturers take note when certain problems arise??

Ford spec A1/B1 oils, there the lowest spec of semi sythetic. As long as its semi synthetic your nikkasil liners will be fine.

hmm, disagree tbh, the engines are designed to have high temp high sheer low viscosity oils, and just because they are the lowest spec of synthetic doesn’t really mean anything tbh, they may be low spec compared to some oil but they are low viscosity high temp high sheer, which is the important bit

And how many people knew this when they were bought brand new?
Dont you think its a bit ott for a car thats probably been filled with non-anal oil by previous owners?

Why would they need to be lined??Couldn't they just have been bored out and left at that??

i would think most people use the right oil tbh, any motorfactor worth their salt will ask you what car you want the oil for and then sell you the right stuff

Have you seen halfords guides at all? They dont exactly match the manufacturers specs all the time.

clearly it has happened to people as i have seen images of knackered nikasil lined bores
you could also say the same goes for making sure your oil is topped up frequently as low oil in these engines is pretty much fatal as well

Don't you have to take mileage into account when choosing oil too??
Like certain oil manufacturers sell oil specifically for cars with high miles.

HTHS is only applicable in extreme conditions isn't it? Like engines way outside the manufacturers spec, heavily modified or running under load for a long time etc.
