It was suggested to me by paul.h to put silicone sealer around the putty in the lights.
I was thinking of using a hair dryer first and then leaving the lights on a radiator to dry out the putty.
How long do you think this will take, any other ideas?

I had problems with condensation when i first had my car 7 years ago. Solved mine by drilling a small hole in the bottom of the casing to allow the movement of air and never had another problem with it. Also did the same to my indicators with the same results.

About 6 yrs ago I bought a pair of headlights from Justsuds, unfortunatly due to poor packaging and TNT (Kittens an twits) they turned up smashed, I have had many deliveries for work from tnt including 36 dry wipe boards to which 30 were rejected due to footprints embedded in them, all the same type of print as well. I think the drivers just asume they can climb over parcels even tho they are labelled "fragile".

Anyway so rather than throw away the reflector and plastic bits I carefully cut my headlight glass out, as I was doing this I noticed there is a small drainage hole in the bottom but only 1 not really enough to circulate any air. So after silicone the old glass into the newer shinyer reflector and leaving 2 holes in the bottom they look really good.

I would leave the silicone for 24hrs in a dry place but you can duck tape the glass on whilst the silicone does its stuff if you need to use your car.

Drilling holes is the answer Al, ive done it too, works a treat. Dont use a huge drill bit though, a 2 or 3mm is fine. Never thought of doing it to the indicaters though, thanks for the thought Lee, might copy you there.

Remember i have ser 3, there is a white plastic cover, covering a hole on the back, to the side of rubber cover, i had one light that was missing one, I replaced the cover and it made no difference.
When i say silicone, i mean smearing over the existing putty, my question was how long to use the hair dryer and how long to leave the lights on the radiator to dry out the putty, otherwise i would be sealing in the moisture.

I had an idea a while back to take out the glass and get a copy made in plastic.

Lol alex
O.K a compromise, I will take off the lights, clean the putty, hair dry out the inside and leave on a radiator for a day, then seal up the putty, leave for another day and fit back on. If I still get condensation, I will try and use a drill.

O.K guys, i will drill one hole at the bottom of the light if the sealer fails and take off the white plastic cap. I think drilling a hole in the top is asking for trouble, as in water going into the light.
Thanks for the suggestion Smile

Guys,

Are you talking about drilling a hole at the back (grey plastic part) under the bonnet or in the front clear part( Shocked )?

I have a condensation issue too. I live in humid Uruguay!

I've not done this yet but need to. I suspect they are drilling in the plastic area underneath, just to get some ventilation in there.

By the way, welcome to the forum. do sign-up so we know who you are and tell us about running a 33 in Uruguay.

Hi Jeremy,

Sorry didn't realize I wasn't signed in.

I'm a regular on alfaowner.com and found this link recently.

I'm British but currently live in Uruguay with my Uruguayan misses and 6 week old son.

Very Happy Very Happy

I own a 1988 33 1.7 QV 8v carb. My second pride and joy (new son being the first of course) in case my wife is reading this Laughing Laughing Laughing

I have some photos posted on alfaowner.com under Brit01.

Haven't figured out how to post here yet.

My 33 is like new. The previous owner was a classic car restorer/mechanic so he basically rebuilt it from scratch.
130,000 kms on the clock.

Recently put in Magnecor 8.5mm cables and K&N filter. Just changed my Bosch plugs (heard they were bad for the boxer), for NGK B7ES.

Difficult to maintain my car here due to the condition of the roads and disregard for safety and other peoples cars. (dings/scratches etc from parking). Very much like Italy. (Well the Uruguayans are descendants from Italy/Spain mostly).

Thxs
