Trumpet "Glue"

[Pilo-Wedgebits]

Hi guys,

I've got the plenum cover and trumpets off at the moment. Any idea what I use for refixing the trumpets in place and for resealing the cover?

Cheers

I used JB Weld. Buggered if I want to get them out in the future, but thats better than having them come out all the damn time.

Hi,i think V8 used clear silicone sealant,John

Visited Eliot (http://www.mez.co.uk/) yesterday with my SEAC's plenum etc.

Most of my pipes were completely lose and there was signs of damage inside the plenum chamber.

As a simple repair and minor improvement in flow he suggested first trimming 10-20mm off the base of all 8 tubes, cleaning the plenum base before using Locktite to fix them in.

Tons of stuff on his website above.

I'll be repairing mine over the next few days.

I use "hylomar blue" to deal the plenum bits back together, but it's no good for the trumpets, so use lock tight.

[Pilo-Wedgebits]

What type of locktite do you guys use / recommend?

Probably blue (planned this to use myself), because red will fix it forever.

Not talking out of experience yet, and also looking for the answers on here as probably in a couple of weeks I will take the inlet apart for the first time.....

Isn't this metal-metal? In which case can't you get a blowtorch on it if you ever wanted to free them up again? So use the strongest adhesive you can get your hands on.

I suspect I have loose trumpets again. To all the guys who posted above - what did you end up using 2 years ago, and are they still in place? I used a blue silicone on them last time supposed to be rated for 500C but I doubt it is really... Is the loctite red referred to the same stuff you use on big end bolts and the like? I've done a bit of research and it seems the best stuff for sustained high temperature might be Loctite 648. It comes in a red bottle but the stuff itself is actually green...

Loctite 620.

Trumpet 'glue'
Sure is an innuendo in there somewhere.....

Few years ago, had a trumpet come loose inside and had been rattling around for a while before I noticed. It was so loose, it had worn the seating whole, had to use chemical metal to fix it back in. Still tight.

Yeah I had a look at the spec sheet but 648 actually has better high-temperature performance. As the trumpets in the SX get regularly exposed to 100C+ I think that's quite important...

Time for a plenum insulator then...?

[adam quantrill]

Actually no - it's the air that's at 100C, the metalwork is engine temp (80-90C) so in my case the metalwork conducts heat _away_ from the air... this confition only happens on closing the throttle though after a blast so it's not a big deal (apart from for the trumped glue...)

Got my glue today - 10 tubes for £12 - so I have refitted the trumpets this evening - only took an hour (inlcuding going round a mate's house to get a tool....) Only needed one tube of glue to do the whole lot so I'll be bringing the rest to BBWF for the autojumble. Some of them were quite loose again so hopefully this will sort them out once and for all...
