Gas and Diesel Mechanic, how can you tell?

[Doc Diesel]

I would like to think that people are intelligent enough to know that there are two types of engine mechanics, mainly gasoline and diesel.

Although there are only a handful of these diesel mechanics, a great number of gas mechanics pretend to know it all such that they try to do something which they don't have the knowledge on nor the tools to do it.

So pls., if you value your vehicle and how you maintain it, look for an appropriate mechanic. You can tell from his advises or diagnosis what kind is he anyway.

Like this post from a supposedly knowledgeable guy..

"Kung minsan kasi ang pinagmumulan ng white smoke. Yong may crack yong cyl head. Gawa ng overheat, magblowby din siya, pera kapag ganyan. Try mong paandarin ang makina mo at habang matagal na umaandar. Try mong pisilin ang radiator hose mo. Pag matigas. Singaw or may crack na radiator mo. Kasi nagkakapressure na. Try mo ring paandarin ang makina mo at tangalin ang radiator cap. Pag ang tubig lumalabas sa filler ng radiator, posibleng sa cyl head gasket or may crack ang cyl head.

Mahaba kasi explaination kung paano malalaman ang IN & Ex valve leaks. Pero bigay lang ako ng Isang tamang paraan, Kung may compression tester ka. First Kung Diesel tanggalin yong Glow plug at doon ikabit ang Comp Tester/ Tapos start ang makina. Kailangan nakadisconnect yong shut off Solenoid. Check mo ang compression tester kung ilang psi o wala. Pagkatapos tangalin ang compression tester at lagyan ng Oil yong yong cylinder. Konti lang mga ilang drop lang. Tapos kabit mo uli ang tester, Start uli ng makina. Kung hindi nagbago. Singaw ang Valve. Pero pag nagkaroon ng pressure ang problema ang Piston or Piston Ring. May mga mekaniko na expert kahit di na gamitan ng compression tester. <-------------read last statement........

Diesel mechanics are very different from that of gas mechanics. I asked my brothers' car mechanic one time while he was top overhauling the gas engine of my brothers' car a question kung kaya ba nya mag-overhaul ng diesel engine. Well buti pa sya honest and sinabi nya sa akin na dalhin ko na lang sa diesel specialist ang ride ko. From then on naging interested ako sa difference ng dalawa at nalaman ko na malaki nga ang difference.
