Throttle body gasket thickness?

[Vakito]

Hi all, I'm wanting to clean my throttle body on my K-Jet '88 240. Only problem is none of my local parts shops or dealers stock them and they cost a fortune off the internet in the UK. I'm planning on making one myself but I need to know the thickness of the gasket used if anybody knows.

Thanks

I've always assumed that as a general principle gasket thickness is immaterial except in special applications (eg cylinder head), or if the spacing of some other attached component would be affected (eg V8 inlet manifold).

I've no experience of your particular engine, but I can't imagine that the spacing of throttle body to manifold is critical for any normal gasket thickness.

A cornflake packet should be fine

How much is a fortune? I wouldn't be too concerned about thickness within reason but I would be concerned about material used,time to source it and time to create it allowing for takes two and three. As a reactive maintenance engineer with often no immediate access to spare parts to get a machine running I have made innumerable gaskets and seals. Very sharp razor knife, a 10mm ball bearing and a small ball pein hammer are the best tools. Have fun.

Reviving an old thread here...

I was looking for a throttle body gasket for a B200F, and they are £20 online for a small piece of cardboard.

The obvious thing is to make one - but is it really OK to use a cornflakes packet, or is it advisable to use gasket paper like Flexoid as available on ebay?

And if so - what thickness?

I have a Corn Flakes packet - genuine Kellogs - which is 0.6mm thick according to the vernier calipers.

But searching online for specs of various throttle body gaskets from other brands, the thickness seems to be 1.4mm and greater - more than the genuine OEM Kellogs brand card board.

And - if I do use Kellogs, should I use any sort of grease to help the seal and saturate the card board?

Thanks again,
John

Hi John,

I make gaskets for fairly low temperature things (like carburettors and throttle bodies) on bikes and cars quite frequently. I keep a few sheets of Flexoid (between about 1 mm and 0.25mm) in the garage, I think that is much easier than trying to cut round a bit of a cornflakes packet, and it is a really cheap material (less than £1/sheet if I remember correctly - a sheet lasts for years).

You are right that individual gaskets are often a daft price, and on top of that one has to order them, wait for the mail and hope it is the right one. It is far quicker, cheaper and easier to make them oneself, so I'd recommend getting a few sheets of Flexoid (get a few sizes, I should think 1mm would be right for a throttle body) and making the gasket yourself. Keep the rest of the sheet for the next 10 similar gaskets you need :-)

I always locate paper gaskets with a smear of bearing grease (or any other grease that comes to hand), there is no need to saturate it but you can then see it is seated properly when a tiny bead of grease oozes out of the joint.

Good fortune,

Alan

Try ebay:~
You can get most gasket material/thickness/size (Oil proof card) at reasonable prices- as previously mentioned make your own and save a lot!

just buy one from the dealer a green gasket like this is usually just a few £ . you will probably find you can re use the one that is on there , they are pretty robust . non volvo ones are very poor , Renault use black ones on their engines they buy from volvo and they cause all sorts of problems .
