Throttle Body Gasket

Post Wed Jun 07, 2006 8:40 am

Does anyone know if the throttle body gasket can be re-used? I need to change the temp sensor on my M40, and was wanting to know if one can re-use that gasket, as the BMW dealers do not have it in stock.

It may start leaking in air.

Try ECP or GSF

Thanks for the offer mate, but I'm in South Africa, and am wanting to do this on Saturday. I think I'll just buy some gasket paper and make it, as the stealers said they never had the gasket in stock.

Do you need to use any gasket glue, or do you just use the paper gasket on it's own?

I realised you where in SA, no problem if you want it quick.

I wouldn't use any sealant, BMW never do so why should we? Just make sure the surfaces are very very clean. But its upto you, I just think it make more of a mess if you need to remove it again...

Oh by the way I managed to replace both the blue temp sendor + Brown one on a m40 withough removing the throttle boddy or inlet.... wasn't easy though

I think it's just a lot easier to have a bit more room to work in! I prefer having a bit of room to work in!

As far as using sealant goes, that's why I asked if the gasket can be reused, as you can see that no sealant has been used. Just as a by the way, do you have to use sealant when replacing the thermostat housing?

I'm pretty sure bmw don't I have had no problems not using sealant before.

If your TB gasket looks to be in good condition, in all fairness it will probably be OK.. But its upto you.

Its all about making sure the surface are clean and flat.

A smear of grease on both faces of the gasket is all required. This practice means that IN AN EMERGENCY (roadside repairs) gasket should not tear so can be refited ( in an emergency) also means no ugly goo sticking out of gasket edges.

Pardon my stupidity, but in all fairness I am not a mechanic!

What grease do you suggest?

I dont think any body said anything about you being stupid.
Basicly any type of grease, its just to form a wet seal against the faces and as previous post usually allows casket to come away cleanly.

Just a bit of further info re the use grease on gaskets. A few years ago for my sins, I worked on fuel tankers (non petrol).
How many leaking joints, pumps, filter housings I saw with all different types of sealing compounds round them I can not count.
On every occasion leaks were cured (with the exception of finding damaged surfaces) by strip down and cleaning of surfaces, gaskets and O rings assembled with grease.
And fuel is hard to stop leaking as it disolves sealants.

Actually in that place when you were sucessfull at something that permanantly became your job (rather than spreading experience through workforce) Guess who got all the pumps and leaking housings to do ?

sealers are good when used correctly.....i.e dirt and grease/oil free...
but average joe usually wipes it with oily rag and slaps it together...

in this instance i would:
check faces for marks,indentations,scratches etc,put a straight edge on it to see if its true..if its a1 ,gasket only is required(but i too do use grease now and again,because it is a good way of holding a gasket in place till torqued up.)

but if the parts are in a bad way -i then use a sealant,on a totally clean surface!brake cleaner aerosols are good for this!

I have allready mentioned surface cleanliness and condition.
When you have seen a big string of silicone, looking like a dirty great florescent snotter hanging out of an engines oil pump strainer. It puts you off the stuff.
