Under Bonnet sound proof removal

[will lyons]

As this topic has been raised numerous times and I have decided to remove the soundproof from my 87 Turbo because it was breaking down into tiny particles covering the engine in sooty black foam bits I thought I would post Pictures and procedure to complete

I use a roll of garden weed supressor felt to protect the engine or bodywork when working on the car it is cheap disposable and excelllent for the job. when working in the engine bay I place 3 pieces one on each wing an one on the badge panel or as can be seen here the engine is completely covered to protect it from the debris of the scraped off glue.

First of all cover the engine and scrape away all of the foam back to the glue surface which lays beneath I did this last weekend

Today the engine bay was covered again and I used tar and glue remover sprayed liberally on the glue surface leave a minute or two so it melts the glue to a tacky soft state which can be scraped away using a plastic blade scraper, Here we are using a paint guard for cutting in bought from the decorating section of a DIY store .... it was in the decorating box and has prooved to be ideal to scrape away the glue without damaging the paintwork. It IS a long laboured job and perseverence is no doubt the key to success also very messy but the result will be a polished paint surface on the underside the bonnet was fully painted both sides as new.The later 250 turbos did not have the panels and have polished painted undersides

It is a horrible job, isn't it! I think if I was to do it again I'd remove the bonnet and do it off the car. Although it's worth it just for the entertainment of watching steam rise from the bonnet when it rains lightly

Wow, thank goodness I've never had it on my cars. Would definitely have considered removing the bonnet first though, would have enabled much easier access to work on it.
