Yesterday, I got my next door mechanic who claimed to be a locally German trained vw bug service mechanic 35 years ago—he said that those days they were already practicing zero tolerance and he failed 3 times in his vw bug engine service examination. He said that they (Germans) will remove/replace items in the bug engine and the trainees have to spot what is missing/incorrect—screw-minus 1 point, spark plug cool air block rubber seal-minus 30 points, coil output rubber seal-10 points, wrong size nuts/bolts-5 points, and so on.
I got him to take a look at my bug (restored to original conditions) within 3 minutes I got a minus 30 points. Minus 10 point each for; 2 missing engine tins under the head (one on each side) http://www.bizpos.com/vwbug.images/enginetin2.jpg and missing rubber seal on the coil output cable to the distributor. I replaced those missing tins from the junk yard.
Got a minus 30 point for missing engine tin

hi guys....i reli wouldnt pin sagaboy down coz im from the same country he hails from and ive seen people who have chromed the whole engine tin, silencer, air filter, etc... in fact one dude from south malaysia decided to gold plate the air filter, fan housing and a few other components....thats how sick these people are. so sagaboy is much better than these few nuts. the cars which have chromed engines it seems spends an hour after each drive to clean the engine up. and these guys also experiance heat build up and finally overheating....so from what i see these rich clowns have more money than brains... so sagaboy...as a person who has colour coded the engine bay with black and silver, i sympathise with you....

nah...in my case i only painted the engine tin black, the a/c pump black, the ignition coil black the air filter cover black, the oil cap black. the fan box, the lower part of the airfilter and the dipstick handle i painted them silver. i changed the tar board also...sum dudes in malaysia used asbestos sheets and sum other used chrome plates to do away with the tar board. tc

It’s been like that for the past 12 months and it’s a daily drive--there is absolutely no reason for a well maintained stock engine to be dirty/messy

I have seen factory fitted original chromed ones too!

That’s special silver paint given to me by a friend from ICI paint test unit—this silver paint conducts and dissipate heat… I have even applied it onto the muffler—excellent stuff—welcome to the 21st century)
“Ford” famous saying: you can have any color as long as it’s black. Looks like black is vw favorite too—since it can cheaply hide all the dirt in the engine compartment.
According to many so called “heat” expert proclaiming chrome engine can heat-up an a stock engine—hogwash!
Basically, the stock bug principle is to suck cool air in from the top and blow-out/keep hot air down and out at the bottom—the tins can be any colors/chrome and WILL NOT cause the engine to heat up any more than what most bug owners “imagination”—if your stock bug engine heat-up—the problem always lies elsewhere and certainly not due to the colors/chrome of the tins.
Since I have licked engine heat build-up problem—Nah!—Wrong choice of words—Actually I didn’t do anything special--just made sure that all the original tins is in place, no leakage of cool air from the blower, 20/50 dino oil, clean tranny casing with 75/90 oil, correct tuning/gas/type of spark plugs—there is absolutely no reasons for the stock engine to operate above its temperature range.
Try this… wait till dark then use a 250/500 watt spot light and shine the light from under the engine with the engine door opened—I’ll bet your engine compartment will look like a Christmas tree—it means that hot air getting sucked back into the engine.
Or this… in the morning when the engine is cold, start it up and with the garden hose and jet water right into the fan-house cooler air intake hole and pump-up the idle speed—I’ll bet that shooting stream of water leaking out from every nook and corners—it means unnecessary losses of cool air that should be cooling the engine.

slow down. yes you're wellrunning engine probably won't overheat from chrome, but that does not prove the whole effect of radiation is completely mythical.sagaboy wrote: Basically, the stock bug principle is to suck cool air in from the top and blow-out/keep hot air down and out at the bottom?the tins can be any colors/chrome and WILL NOT cause the engine to heat up any more than what most bug owners ?imagination?

For metal to *radiates* heat it must first absorb heat
therefore, the idea of using black is its properties/ability to absorb heat wavelength—hence, black paint act as a heat transfer agent to the metal tins for dispersion--therefore, a running engine heat gets dispersed by forced air flow.
And when the operating bug engine is switched off—the remaining engine heat plus those absorbed by all the tins *radiates* out—but absolutely play NO part to cause a running aircool engine to overheat.
In the micro level management of aircool heat—chrome is much less efficient in absorbing heat compared to black--therefore, more heat gets blown off (out) the bug and makes the engine runs cooler and since it (chrome tins) absorbed less heat—when the engine is switched off—less is being radiated…. LOL

hie sagaboy....for one im impressed coz u sounded like a guy on discovery channel making a report on how an air cooled engine works. lolz. neway i like our theory. the fan box, the dynamo and the air filter is sprayed silver on my car. the balance...every part of the engine is colour coded black. or grey coz i neva got any paint to touch those areas. besides, the mercedes folks use to brag about the durabilaty of their so called 'black-engines.' is it is durable.... but not much of a difference in malaysia. this is because it suppose to retain the heat from the atmosphere allowing it to start up effordlessly in cold climatic conditions. hence, europian countries. neway my lil cousin learnt at the age of 13 that black cars trap more heat than silver or white cars. u may be right in the fact that the fan box is silver hence it doesnt absorb much heat. however, the mc laren F1's engine is gold plated! that is mainly to to release heat effectively.whatever the case maybe, the abosorbtion of heat or whatever it maybe due to the colour of the engine to me is just a small difference so negligible that unless u are making a super-car it wont matter much. besides, if it was so in the VW owners manual it would be stated "do not spray paint your engine any colour other than black" i dont see that too. anyway, from what i see hardware like cooling fins and fans and the location of the engine is more important than the colour of the engine. well i am a newbie who has a lil knowledge of physics but one thing that i do know, im happy with the colour of my air filter and fan box....regards, dev
