What causes gas in oil - Mazda 6 Forums : Mazda 6 Forum / Mazda Atenza Forum

audiofreak19 · 11-18-2012, 04:25 PM

So as most people know I have a rod knock in my 03 m6 and i still drive it even with the rod knock cause it hasnt lost any power just the knocking sound. Anywho, I noticed that when I was checking the oil when it had the rod knock and I didnt know where the oil went cause it wasnt leaking out the bottom anywhere and I thought it was just burning it for some reason but didnt know why cause I dont have any check engine lights on. So I had been monitoring the oil very closly to see if after i filled the oil back up if it was burning the oil fast and what not and for the next few months the oil level didnt go down at all so i ignored it for a little bit. Well yesterday I just checked it again and there is almost no oil on the stick. But here is the catch it smells like gas. And I took the oil fill cap off and smelled it and it to smelled like gas. What would cause gas to get into the oil? Im thinking something injector related but I dont know what cause its not throwing any codes

Your rings are probably bad...

I would stop driving the car man. Get that motor taken care of.

So question. I wanna either get a new motor or rebuild it. Which would be cheaper if I pay a shop to do it cause me and my dad don't have the time. I still have a project car in my garage that's been there for 5 years cause we don't have time. I figure if I rebuild it it will be stronger an it's hard to find a used motor around my way without paying 2k just for the motor. Any advise

If you aren't doing the work then replace. If you do the work then rebuild.

Ok. I wonder how much a motor is gonna cost from the dealer and for them to put it in. I don't think I have any shops around here that even semi specialize in mazdas that aren't rotary

Dealer is going to be pretty steep.. Probably double of most other places.

tapatalking.. err wait.

If the rod bearings are going/gone the piston is under extra load and rocking in the bore which creates MORE blow-by during combustion. The burned and unburned A/F goes past the rings & piston into the oil.

How many miles on this and how often was the oil changed? Just curious. . .

audiofreak19 · 11-20-2012, 04:25 PM

The car has 112279 on it now. I had a couple people offer me 2500 for it but I feel it's at least worth 3k in the condition it's in being that it still drives. What do u all think. The oil was changed about every 4 months or 4k miles if not earlier

audiofreak19 · 11-20-2012, 04:32 PM

So I just called the dealer just to find out how outrageous it was gonna be and he said for just a short block 5500 installed and he said they would have to inspect the heads and I asked how much to replace them and he said tack on another 2k so 7500. I have a feeling I am gonna have to wait it out a while
