trying to install O Ring - Throttle body into intake manifold....

I just replaced the left cam chain tensioner on my 99 RT with the upgraded one.
Looking for any helpful tricks to get the O Ring to stay in place when slipping the intake manifold back over the throttle body?
The O ring is a little loose and gets pushed out of the groove when I try to slip the manifold on....grrrrrr
Thx.
 
If you're trying to re-install the old o-ring that could be the biggest part of the problem. Again, if it's the old one, it out of shape from use. You could try holding it in place with some grease. Not sure which, but freezing it or putting it in the sun - one of those should shrink it.

Okay - I just looked it up. Boil the o-ring (boiling water) for a minute or two. Remember, this advice is worth exactly what you paid for it.:)

Thx for the reply. Tried freezing. No joy....will continue to fiddle. Probably should get a new O ring. Are they relatively tight on the throttle body when new?
 
Hot water.....no joy. I guess ill go to the local Beemer store tomorrow and get totally hosed for a $0.50 Oring. Uggh
 
Yes on the tight when new. If it's wiggly loose, it's due anyways and your dealer will enjoy the visit:wave
Yeah, the OEM is $7 ea...crazy I know

Have had some luch rolling TB or intake tube a bit with a bit of soap solution and it stayed...that time
 
Success! I got er done! I just had to fiddle the bejeezuz out of it.
Might still go the dealer tomorrow though. Call it a gravitational pull by that K1600B....
 
Common problem. Especially when used - they swell from fumes and oil.
I now cut out 1/4" with a razor blade and use a drop of crazy glue to join the ends.
Lube also helps.
