Reports in car mechanics give it the thumbs up,

its a 50/50 chance that it will work..

i have used it, and it worked but first try the following.

start engine and listen for noisey tappet.... if present raise rpm to 3000 and

hold for 10 secs.

release throttle and listen.. gone.... good

still there. turn off engine and wait 10 secs, start engine and listen....

if still there repeat


depending on how bad or whats caused the tappet to stick it may free.


mine tend to get noisy :

nearing an oil change

when the scoobs been standing for some time


generally if one wont pressurise after 3 attempts at the above and flush its time to change it...


oh and because they dont show any signs of failure, you have to do all 16, and i think there about 12 each ex vat and labour

i used it and i think it worked which me... It purports to clean the little hole on the lifter so oil can fill it properly, but i don't see how this would work without some *serious* detergents, and if they are that serious, i don't want them swishing around in my engine.

Here's a quote I found interesting from David (APi engines)..

Assuming the noise doesn't fade after a few minutes from start up it is probably gummed up or weak hydraulic lifters. It is worth trying to clean them up with a simple but effective remedy.

Drain out half a litre of oil from the engine and refill using 1/2 litre of ATF auto transmission fluid. This marketed by a number of companies as ' hydraulic lifter cleaner' and you'll pay a tenner or so for about a cupful.......

My way should be rather cheaper and just as effective.

After 300 miles with the cleaner in drain off all the oil and refill with oil of choice and a fresh filter. Try not to red line the engine during the 300 miles just drive ' normally'

what caused mine i think is it had wrong grade oil put in-apparently zetec engines are very fussy what oil they have-and wrong oil was only in for about 1000 miles

Last bottle I looked at was just various detergents and viscosity improvers.

You get the same from changing the oil more often. Which lack of regular oil changes is the usual cause of the problem in the first place - especially on the iron block zetecs, where IMO Ford's service intervals were pushing the limits of the recommended oils they used. When Ford switched to the thinner oils to address pump up issues, it didn't help matters. As the thicker oils they used to use were better at keeping them quiet when hot.

Oh right it's worse when cold, so a tappet is draining down overnight and not re-filling. Ignore my rubbish on the thicker oils then

A drained tappet causing slack clearances won't cause the valve to the burn out, as the clearance actually means the valve is shut and the noise is caused by the gap between the tappet and the cam.
Unfortunately, now my brain has just kicked into gear - there is a flipside where a sticking valve causes the same noise (and that will burn out). The latter very rarely happens these days unless you have bent valve (usually from a cambelt failure that's not been correctly repaired) or excessive varnish deposits on the stem (never happens in this day and age), so it shouldn't be anything to worry about.

More likely to be a gummed up tappet.

Personally I've had limited sucess in using tappet treatments products. Sometimes they work sometimes they don't, and in some cases I've had improvements by changing the oil at several close intervals. And some fix themselves after a good long motorway blast with the revs held above 3000rpm for an hour or so. Not much help, but that's the way it is!

More likely to be a gummed up tappet- Can I hazard a guess...right hand side of the engine on the exhaust cam? That usually the favourite.

Advice from David from API is always good since he knows what he is talkng about. I would try what he says and if that does not clear it then you have to be prepared to change the tappets.

Am I the only one wondering why this thread is in NSR? It's not like we can blame Tony Blair for conning us into buying flushing oil is it?

Is it?

i,m going to be totally honest and say, i've never know a such a model of car that comes with so many foibles, quirks and subculture as this.

I,m not disputing anything youve found or know, and i respect the knowledge of these engines to you is far greater than mine.

but,, hells bells for a supposedly robust engine its more fussy than an F1 machine

lets be honest if joe public knew all this as they walked into the showroom, i bet half of them wouldnt touch a scooby with a barge pole..
