Airbox Removal

[Paul Mason]

Got an airbox on my car, not sure what type, but some of the documentation with the car (old advert) refers to it as a Bernard Scouse?

By all accounts it’s previously suffered from ingesting a loose trumpet bolt and doing a little damage, so in an effort to prevent reoccurrence and to settle my own mind want to check them every so often as a precaution.

From what I can work out, seems to be about 5 nuts attaching the airbox to the throttle bodies via a metal backing plate (pretty poor photo below but the only one less than 2mb I can upload). Before I start, just want to check that these are the right nuts and it’s just a case of taking them out and removing the airbox to get at the trumpets and check their bolts?

Bernhard Scouse airboxes are pretty common with Jenvey DTH throttle bodies.

Undo the 3 bolts on the top and the airbox will (with a bit of a wiggle) lift off the backplate. It located into a couple for slots on the lower edge of the backplate.

You can then check the bolts holding the backplate/trumpets in place. They should have had thread luck applied when they were fitted.

Hi Paul,

It can be a pig to remove, on mine I have to loosen the clutch cable nut off and push as much of the outer cable as possible back into the pedal box. I also filed the tabs down a bit to make it easier to fit.

Check all the air horn nuts and studs as they seem to come loose, I used very strong loctite.

Many thanks p.mole 1. Will bear that all in mind. Am wanting to do precisely for that reason as a precautionary checked of the nuts and studs to make sure all is well and will double check with loctite too.

Out of interest, and forgive my lack of technical knowledge, but does the airbox contribute to oomph or is it more a noise suppressant? I quite like the thought of having an interchangeable set up between airbox and sausage type filter if I want a more rorty driving experience ever? But, don’t want to impair the map that’s on the car?

Cheers

Hi Paul

I have suffered an engine rebuild because of a securing bolt coming loose and the clip being ingested. The solution I have is to drill through the heads of the bolts and then use lock wire so that they cannot come undone. There are five bolts; two at each end and one in the middle. When the end bolts are tightened I lock wire them together so neither can turn. The middle bolt I lock wire to part of the throttle assembly.
