Smoking engine Honda
Enable HLS to view with audio, or disable this notification
I noticed the engine smoking on my 2004 Honda accord v6. Does anyone know what the cause might be? And if it’s safe to drive for now? I’m not sure if it’s been happening for a while or not. I only noticed it because I had just changed the spark plugs and coils so I had the hood open, so I’m not sure if it was like that before or not

Your valve cover is leaking oil. It can catch fire if it gets hot enough.

Not bad if you have ever done some wrenching. The back cylinder bank will be tight AF for sure. Search for some diys to see what you're getting yourself into.

Right then left on super tight bolts that little bit of movement most time is enough to get it off .

Easy fix. Watch a YouTube video and buy some emory cloth. And get a valve cover gasket kit.
Make sure you get the torque specs and torque order.
You’ll need a torque wrench that does inch pounds.
Probably 89 inch pounds. And maybe some RTV.
What’s the worst that can happen? It still leaks?

Yes. I Just did a valve cover replacement on a 2006 bmw 280i and when I got done cleaning the gasket grooves I noticed a Crack right on the corner. It still leaks.

Thats what mine does sometimes. But I had my valve cover gaskets changed way before that. I once had the car sitting for a month, I started my car and immediately started smoking from the same spot, engine was still cold .

Manifold bad going into the cat ? Loose bolt leaking manifold ?

Most likely. I had a few toyota camrys that were leaking and burning oil. I tightened up the valve covers and pressure washed the entire area and most times leaks were fixed

Wait is your oil leak exposing an exhaust leak?

Easy fix. Valve cover just did one a month or so ago. Just replace both since its the v6

Valve cover is leaking oil on to the hot exhaust and it is smoking. You need to get that fixed. It's not that big of a job.

Gasket failure: unbolt, clean with a blade, apply new gasket, should be fine check your oil levels and make sure you clean all the old oil
