Smoke from engine bay - Honda Prelude Forum

sameujo · 10-09-2006, 12:06 AM

I've suddenly been noticing some white smoke from the engine bay. It's not ALOT of smoking that it pours of the hood while it's closed but enough to notice it. The white smoke is coming from somewhere underneath between the engine and the firewall. More specifically, it is in the area below the fuel injectors close to the throttle body. Any ideas or suggestions?

Could be oil leaking from the oil cooler/filter onto the exaust?

White smoke can mean a blown headgasket causing you to burn coolant...

Also, have you changed your cam seal? those are known to leak but is not going to fix your current problem...

Chances are oil cooler o-ring. Had same problem on my 93 VTEC and that was what it was.

Perhaps the radiator? Mine had a leak in it and did this. Replaced it and it was all good.

I checked again, and it is not coming from the radiator. I'm not sure if it's a gasket or not...but the smoke is coming up from the engine bay behind the engine between the engine and the firewall. It's coming up from the bottom so I can't really tell where it's coming from. I've taken a flashlight down there and it is still pretty hard to tell.

What does it smell like? If it's an oil leak it will have a distinct smell and a different smell if it's coolant. Probably oil leaking down the backside of the motor.

Its easy, jack the car up, get under it, look up at oil filter, look for oil leaking from the oil cooler its attached to.

Could be a coolant hose that's busted. I had some white smoke coming out of my hood a few years ago, it was coolant that was leaking on the front of the engine so when I got to a stop in would fall on the exhaust manifold and go up in smoke.
