[Healeys] Bonnet Louvers

[Dr. C. Rubino]

Well Peter if that was the case  with Healeys why did I get oil on my 
windscreen the other day.

I have had louvers (custom) in my hood BN-4 Longbridge with center crease 
for 10 years. On two occasions when I had replaced the gasket on my valve 
cover and hadn\t tightened things down enough, obviously I had oil spray in 
the engine compartment and of course because of the louvers, on the wind 
screen. The beauty of this is that without the louvers I would not have 
known what was happening until my oil pressure disappeared or I parked to 
find a puddle of oil.

No I wasn't blinded as it was easy to identify the first tiny drops that 
appeared which alerted me to pull over and check what was going on. I am 
convinced they assist in cooling down the engine compartment as well, and 
boy they look great!
