Yet Another Headlight Question....

[griff430]

I finally took the plunge and extracted the headlight pods from my Griff to give them a thorough cleaning. After having seen how the ventilation fan is situated, behind the near side head lamp, I can understand why the cabin airflow is not always that reliable. Whilst refitting the near side pod, I've noticed there is a gap in the engine bay where the pod flange protrudes from it's housing and into the engine bay. Obviously this gap needs to be there to allow the pod to be removed and refitted, but I'm sure the gap must reduce air pressure being sent to vent the cabin, and may also explain why, that when the car warms up, especially in traffic, the air coming into the cabin is very warm. I know there's a lot of heat under the bonnet that will warm the ventilation pipes and body work, and therefore the air, but I wondered whether blocking the gap between the pod and the engine bay with some expanding foam would improve things? This should be easy enough to remove if the pod ever needs to be extracted again, but I think it would serve the purpose of minimising the amount of hot air that can enter the ventilation duct, whilst maximising the air pressure reaching the cabin. Has anyone got any opinions on why the gap should or shouldn't be plugged?

Thanks,

Dan.

Having difficult picturing the hole in question. Do you have a digital camera?

[griff430]

Yes, I've got a camera, and can try and get a shot of the hole on question. Not sure how well it will turn out though, because it's in the depths of the engine bay, obscured by the pipe for the air filter.

I tried turning the fan on at lunch time, and there's definitely a lot of air being blown through the gap. Air that can be put to much better use in the cabin I feel.

Originally the factory sealed this gap with leather strips.

As you have already sugested, its best to seal it up to enable clean and sufficient cabin air pressure.

Its a mk1 gremlin!

Hmmm... There's no evidence of the leather strips, so maybe the pods have been out before? In the absence of the leather strips, can you recommend anything else to fill the gap? I was thinking of the expanding foam in a can?
