Please excuse my ignorance if the question i am about to put upon you good people of PassionFord,is a common fact.A standard cosworth valve,has anyone ever known one to break?I dont mean by dropping or hitting a piston,i mean break as in head snaps off?I have always wondered wether you ever have to replace them if undamaged.Does the fact the item is a two piece affair have any bearing on strength once of the older variety?I do thank you dear chaps sincerely with your eagerly awaited replies.

Cheers.

 

yes - ask Ian (rs_nuts) - he had a valve snap off at the head and it made a right mess of the piston, bore and head

 

Can you actually verify that it didnt snap because it hit the actual piston?

 

Never heard of them snapping, bending yes (I have 16 in my workshop to prove this).

Only reason you may have to replace them that I can think of other than them being bent is that cleaning and cutting them in may leave the metal too thin, thus making them more fragile.

Exhaust ones are hollow, i.e. filled with sodium, so I guess the metal can't be too thin.

HTH.

 

Any tuning type people wish to express a view?I do however understand this may be a little too complex a subject for most.I apologise.

 

Have a word with Mark at MAD, im sure he could answer such a question

 

I do thank you Frog,thank you.Tiff,if i may call you that?You say to ask Mark at MAD can you explain a little more indepth what you mean?

 

phil dont ever commit a crime as ya too shit at lying

ya need to learn to be subtle and not too spoon fed, its like a 1940's tv ad

 

Why would you not be able to call me that??????

Its as if you know i have another name

 

So we are entering a war of words?I was being polite asking if i could be so bold as to on my first occassion call you Tiff.Now to me Tiff doesnt sound like a first real name,so i deceided to ask as it sounds more of a nickname,and many dont like complete strangers calling to them by this.I hope it clears this tricky situation up?

 

Exchange words with a man called Mark at MA Developments. It is a very good tuning company like you asked for.

Im sure he will be online later so you can make another post,if he doesnt see this one, asking for his input

 

Mr Sandwich

This tricky situation and "War of words" seens to of been resolved, for which i am pleased of.

As for Tiff not being a first real name, i think you will find it is.

 

Suddenly the fog lifts!Yes i have heard of M A Devepments,who hasnt i guess.But does he appreciate being called MAD?Makes him sound like the wrong person to tune ones engine!I will hope he sees this minor topic and has the grace to lower to such a lowlyman as me.

 

Hello Phil - Welcome back

 

Is Phil,sorry i will have to say it once more,i do apologise,Tiffs real name?If so i will call you Phil in the future.

 

Simon

We sussed this about 5 minutes after he first posted

Just humour him for a while

 

Phil,i am now getting confused,please vacate this topic so i can get the answer to this very interesting subject.I am sorry to sound a trifle brash.

 

Tiff, while you are on, Just to let you know, I am becoming a Bosch automotive fuel injection dealer.
Just had enough of white electrical goods sales.

Anyway - Back to the topic - Sorry for interupting Ham Sandwich

 

Thanks Simon

Very handy to know

 

I notice all too often threads diversing from the original content.Phil and SECS maybe conduct business via a PM or e-mail?Or a seperate thread?Food for thought a lads?

 

Indeed Mr Sandwich

Just like you have done on a thread about me selling my car, you started on about my family and my sexual preferances.

Food for thought eh

 

I put my hands up to that,i would like to say however Phil,that it was done with banter in mind.If i have offended you in anyway please accept my deepest aplogies.Lets say no more about it Phil,yes?Lets leave this topic to just pure valve talk.

 

Apologies accepted

 

Can't believe I fell for it

 

What that Tiff's real name is Phil?I assumed he was a well known character looking at how many posts he has acheived!

 

if ya thought his name was phil ya wouldnt have said it in EACH sentance

just give up , its funny but it also makes ya look as sad as galbally
