Hey how's it going?
I having a huge problem with my honda accord.
In a nut shell what's happening is that oil leaks or evening gushes out from the bottom of the engine when ever I turn on the engine. Just to note, I've not had any big repairs on it, just the usually maintenance.
I first saw this when I was driving home on day and saw a trail of oil coming into the driveway. When I saw that, I ended up seeing a huge puddle of oil from the bottom of my car. From the looks of it, it looks like all the oil from the engine gushed out. I checked the dip stick and it was empty.
I first tried putting in more oil, was fine while the engine is off, when I turned it on, that's when the oil starts gushing out. So pretty much I can't drive my accord right now.
I went under and made sure the oil plug > was tight
and also checked the oil filter > was tight
Couldn't really see where the oil was coming from. I guessin' or thinkin' it's either the oil pan or gasket.
I just curious what the problem maybe and what solutions I have. Also, wondering to what the cost might be (roughly) on the whole repair.
Thank you very much
Any suggestion would be very much appreciated
