Default turbo heating up

1992 miata turbo charged td04h (link engine management) (400cc)

swapped my 1.6 motor. For some reason the trubo get really hot on idle. is it possible that there is no oil going to the turbo or is it always extremely hot like that. Didnt pay attention to it before.

engine temp seems fine. coolant seems fine. no leaks. sensors good. engine runs good besides an annoying valve tick.



gotta car show on the 30th.. eek!

Car isnt running excessively lean is it? You also gotta remember it is only inches from the combustion chamber so the air is alittle warm anyways

I start the car on idle for about 2 minutes and I swear i can spit on the turbo and see my spit sizzle. It seems extremely hot. the car has not been dyno'd yet. It runs rich. Is the turbo being over boiling temp on idle normal?

my 1st guess was oil pump or oil pressure.. air comes out of the oil cap so im assuming pressure is working.. im stummped yet again.

Does the exhaust size start glowing at idle...if not, its probably normal.

Turbos tend to get HOT...like 1000*F +



Edit: woot 4k posts.

nothing glows really. How would you be able to tell if oil wasnt flowing right to either the turbo or head?

If the wheel still spins, then oil is flowing. Are you really this stupid?

My answer was going to be something talking about carnage, death, and lots of profanity, but that works too.

I hate to be an ***, but I kinda agree with hustler. Turbo won't last long with no oil.

Would you grab your exhaust manifold while your car is idling? The air comes immediately out of the exhaust manifold and into the turbo.

I'll break it down further. The combustion process builds a fire in the combustion chamber. Would you light a container of gas on fire and stick your hand in it. **** no, it's hot.

Thank you, this post has provided me some relief while studying for my ABR exam. If my wife would ever come home with my lunch, life would be bliss.
