wynns hydraulic valve lifter treatment

[chrisRibiza]

Anyone ever used this? Does it work or is just just "snake oil"?

Do you need to drain any oil out before putting it in? The car was serviced not long ago so has the correct (full) amount of oil, just trying to sort noisy tappets when the cars cold.

Am I likely to make it worse putting this in?

It's for an 07 1.4 petrol sport.

I have used it on an 8v 1.4 6K Ibiza (my daughter's car so maybe different rules!) and it either did very little or nothing - but I still thought that it was worth a try, bearing in mind that engine was an older type and maybe more prone to wear noises from that area.

I'd guess that what these additives try to do is to "de-gum" the system and add some thing that will cling to the surfaces and so dampen down the noise a bit.

If you don't try you will never find out - it should not do any damage, and maybe just quieten your engine down enough for you.

Edit, the quantity of a tin of that would not cause any "over filling" problems - there is enough "head room" to avoid you getting into that situation.

I used it in my old astra bertone when the tappets started getting nosiey. Worked a treat, took ages to come out of the bottle though.

 

[chrisRibiza]

Do you reckon any oil would need drained out of the engine or would it just be a matter of pouring the bottle in?

Don't want to overfill it with oil

I Just put it in there's not a right lot in the bottle iirc.

I'd save my money, drain the oil and replace with a good quality oil. Your just masking the issue. If the tappets are that worn already just have them adjusted/replaced.

Used it in my old rover 25 to great effect. Made a vid to show.

Detrimental effects of adding this stuff may not show up immediately but a few thousand miles down the road you may live to reget it. Oil companies spend millions investing in research to get the correct properties/additives in the oil. Bare in mind that each batch of crude oil is not like for like so they are having to constantly monitor and adjust to ensure its correct.

Do you really want to stick in a bottle of £8-12 additive that quietens your engine in the short term not knowing the long term affect? Some of these additives usually state for short term use only which puts me off straight away.

Each to their own though. Personally, i'd put the money to some good oil, or just get the tappets adjusted which is an easy enough job to do yourself if you have the correct tools.

I think that you will find that the OP has a 1.4 16V petrol engine, and as far as I know, they don't have "bucket and shim" or any other way adjustable tappets - they are hydraulic and they "tap" mainly due to gumming or varnishing up. So, the only way to sort this out properly would be to get the tappets out (after a lot of stripping down), or try something that will try to work on the gumming or varnish and disolve and remove enough to quieten down the hydraulic tappets a bit. That is what that "stuff" tries to do - some it will fix and some it will not, and its meant to be left in for the service period of the oil.

When talking about batches of crude oil being different, remember one thing, the crude oil get analysised (ie broken down), and then built back up to make something useful, or more likely, the crude oil is reduced to chemical fluids and then manufactured into fully synthetic engine oils.

You just acknowledged in your last paragraph my exact point, which is what I said. The oil manufacturer is constantly monitoring crude oil quality for every batch that is used and turned into different oil grades etc so i'm not sure of your point lol.

What I said is pretty much all over the internet from the oil companies themselves. They are strictly regulated to produce a particular quality hence the different ratings on oil i.e. 501.01, 505.00, 505.01 etc etc.

This 'stuff' is not. Its made to 'wynns' own grade/quality etc.

Hey, don't let me stop anyone using it. To me its like buying top premium oil and then topping up the last 0.5 litres with low grade 'stuff'.

I'm phoning tomorrow to get the car booked into get it checked as the noise is doing my head in and getting worse as the weather gets colder. At least it's not tapping while driving...... Yet

You should hear my TDI on cold startup. Rattles like a sherman tank for 5-10 seconds lol. Only starts when its really cold and done it from new. After a few seconds of the oil circulating its fine

Doesn't like being started and instantly driven away in the winter either. She likes to be ticking over for 10-15 seconds first or will virtually stall without huge revs. Very temperamental lol

JPS3290, don't think that I'm to "get" at you, but, rattley start up with diesels is mainly down to combustion noise/diesel knock - you would not stand a chance of hearing valve gear noises during the cold period after start up.

My point on your comments on crude oil is, there is almost nothing that crude oil and engine oil in the tin have in common, its just that we still call "lubricating/cooling fluid" oil, the fact that some of the "ingredients" are derived from crude oils is really just down to what is easiest to get some of them from.
