so I have been doing a lot of reading on the forums. So my engine burns a lot of oil. It is not a saturn, though I have been on their forums for information. Sadly my car is a year that came with a flawed piston design. The year after they added 4 more drain holes in the oil groove. My pistons combined with bad maintenance burns a lot of oil. I was lied to about it, but at the same time I probably would have still gotten it since 5 speeds in this truck is a gem.
Anywho, I have been running synthetic diesel oil for the past 2 years. A few Marvel Mystery Oil runs and thats about all I've done so far. The oil turns black within 1k. I recently changed the valve cover gaskets on both banks and the heads were clean. Some gunk on the covers but nothing major; it was very very minor. I assume there is some gunk on the low end of the engine. And sadly i cant take it off for inspection/cleaning. I dont have a garage or drive way. If I did i would have rebuilt this thing already or put in a diesel.
I am currently putting 100 bucks from each pay check into a savings account which I will use to rebuild the engine eventually. A complete over haul. The improved pistons as well.
in the mean time I am just hoping for miracles. If I could just get the hardened carbon out of the oil rings I will be 100% happy because thats where the problem lays. Is there any product that you guys think would work?
So far I have compiled a list of products that people have had results with, but im not sure what to try or which will have the highest chance of helping me since most of the stuff I've found online is on cars with lowers miles than mine so I assume the gunk in the oil rings has not completely turned into hardened carbon. BTW, my engine has 150k on it.
-MMO piston Soak(what saturn people do, but it seems like the ones with high mileage dont really get results)
-GM piston cleaner(apparently the v8 north stars had similar issues due to grandmas not pushing the engines hard)
-kreen(seems promising)
-BG 109(seems promising)
-protek engine flush(seems to be aimed at the rings, but i wasnt able to find a whole lot on it)
I have even considered some hardcore flushes like B12 despite its high risk, just to get the engine clean so the oil detergent doesn't clean the walls and become saturated and is given the chance to clean the rings. Clearly I'm desperate!
I have not done a compression test so I cannot say whether the oil gets dirty from gunk in the engine or blow by. I can say that when I did run MMO the oil came out really dirty, but like i said nothing on the heads, but some minor build on the valve covers. The engine runs great. Just uses a lot of oil, I'd appriciate any intput on which product would be the best for me, or any combination.
So this is a piston out of a similar engine that I took out many years ago for a rebuilt. This one had about 20k less miles on it. Lots of coking! It wasnt my engine and I never drove it so i dont know what the usage was like on this one but I suspect it was high. As you guys can see the comp rings are not stuck, so I dont think compression is an issue, but that oil ring sure is. I even left that piston in a seafoam bath and it never came lose. But seafoam isnt that hard of a cleaner anyways.
