Payen BK450
Turbo Mini Forums

What the....

right!
I'm now using af470 gskt since two years, and very pleased wit this.Not cheaper to buy but it does in time and assle

So will minispares be replacing all the gaskets that have popped through no fault of the owner/fitter free of charge???

Doesn't seem unreasonable?

I think the AF470 was the same as the TAMxxxx part that was the original turbo gasket.
The BK450 was just a alter improvement.


I used the AF460 once...it didnt even last 15 miles before it blew between 2+3


Cost aside...why dont you guys use the metal shim head gaskets ?

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

How do I identify one of these suspect gaskets? Its on the engine, but I still have the package.

What part of the gasket is the faulty part, I only need the fre rings to work, nothing else

It'll be the last straw if its one of these dodgey ones

at least the head gasket can be done in the car :(

Ok what numbers am I looking for?

Ok some one clever at minispares has stuck their sticker over the bar code and batch number, why people do this, I will never know.

Holding the lable up to the light and decyphering one text from the other, it has a code of 1291. Bought from Minispares Birmingham aroundthe begining of April. I bought two, one was a larger packet, the one last used, and this one, in a smaller packet, says Belgium on it :(

That will put the icing on the cake if its a fucked one

In my mind,
and whatever the bk450/af460 quality is ( it did support silly power/cr/boost).

An Af470 head gasket is better , even more with an ally cylinder head as , it does transfer heat. It's a bit over when you have both iron head an block. then with ally head and iron block, it can make the little difference.

One of my bimmer block had a multilayer Goetze HG, considering your efforts to keep the bores from the k11, perhaps it would be more suitable?

Sprocket,

PM Gavin - mine is Belgium but the 4 digit code is 1256 (so possibly older if the batches run in numerical order) but Gavin obviously has a list of the dodgy codes.

Schrödinger's cat - so which one am I ???

Gavin seems to recon that the gasket I used is one of the dodgey ones.

I have done a little research on my old BK450 gaskets, and the last one I used, measured ~0.94mm thick and the fire rings at the bore intersections appeared distorted. All the other used gaskest I had kept, measured ~0.98mm thick and the fire rings at the bore intersections were un distorted.

Perhaps the real problem is that the wrong thickness base material has been used with the correct and normal fire rings, so when it is compressed, the fire ring distorts more that it should, crating a sharper edge with less suport, exposed to combustion pressure.

I cannot see anything different other than this.

So is it basically - if it says "made in England" it is good, anything else and it is dodgy?

Mine is made in Belgium, but has the no 1320 on it, waiting for Gavin to get back to me.

Hi sorry for the late reply haven't had much spare time to get on here recently. Yes Dave you are correct if it says "made in England" then the gasket is fine, anywhere else and it is faulty. There may be a few exceptions but for piece of mind we will be giving everyone who has bought one a credit if they so wish. This also now applies to the AF470 as well!

Damn n blast I will have to keep an eye on mine now

Can you tell what gasket I have from invoice as i have thrown the packaging away?

If something is worth doing, it's worth doing half of.

so what happens now? are payen going to make them again in the uk

And are the AF470s (which you still show as in stock) the UK ones ?

Schrödinger's cat - so which one am I ???

Bugger, just checked my BK450 for the Mig and it's made in Belgium.

Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."
Stephen Hawking - "The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge."

So I assume by the BK450 aka TAM1521 being out of stock, that they're all dodgy.

However, the near identical AF470 might still be good?

H haaa!

Had a look at the ones left in the workshop and they are FIA branded made in the UK

Own the day

Some of the AF470's have been re-called but we have a few left in stock that are fine.

can you bang a pair on my order gav?

Team Racing

What other gaskets are safe for moderate boost and power output?
