    You try any upper engine cleaner @HawkeyeGeoff had good success with it, if it is a stuck ring causing oil consumption. My car eats oil too but I am making good power. What is your 40-100 ?

    The general consensus on the old forum was that the Cobb ots maps ran too lean .

    Mine was for 93 as well and yeah he targeted 11:1 for me as well. I told him once I get my car figured out ill be back to get another tune from him. And yeah that’s nice to know we can do that!
    [doublepost=1532453851][/doublepost]Yeah im pretty sure my car was running almost 12:1 at wot with the Cobb map. What could cause oil burning other than bad rings? I have already changed the pcv, no oil in ic piping going out of turbo, and unless I did it wrong my motor tests don’t seem to show bad results? I think whatever is causing my oil issue is the cause of my power loss.

    It doesn't look like your turbo is flowing very well after reviewing logs. 100% wgdc for ~16 psi at 5.5-6k seems low. Granted, it's super hot in your logs which could be part of that.

    For reference, my car with a stock 1st cat was making ~18 lbs at 75% wgdc at 5.5k. So I have more exhaust restriction, but it's still making more boost at a lesser wgdc.

    But even if you added 2 psi in figuring 1 psi = 10 whp (probably optimistic) your hp number is further off than that. Cobb maps make 250+ whp.The reason the cobb map is making more power than jasons is because it has more timing and is leaner. Jason's map may very well target more boost up top, but it isn't happening.

    Also, I watched with my eyes that top end cleaner geoff was talking about, AC Delco X66P, raise compression in cyl 3 of Johannas old car and it wasn't a temp fix.

    Yeah I think the only thing left to do is to try out jmiths turbo I got and see if it helps some before my build next year. How do you use that cleaner?

    You take the plugs out and add equal amount to each cylinder, let it soak for a few hours recommend over night, longer is better. Then suck out as much as you can. Take it for a long drive like 45 min and let it rev decently high to get it nice and hot, hoon on it a little here and there letting it warm and cool. Then change the oil and recheck compression if you want to. That is what I did and it did help a little with oil consumption.

    Thanks for the link Sho. I may try that too if the turbo replacement doesn’t help
    [doublepost=1532641544][/doublepost]
    So I took your advice and ordered a new bov that I will be recirculating not VTA (my current set up is already). It’s a Greddy FV Knockoff rated for around 30psi so it should be all good. About to go install and get it set up so hopefully I don’t have to take the spring out and cut it or anything! image.jpg

    Wanted to let all who read this know the outcome or answer to what began this thread. Lets just say a piston ring is apparently worth 100hp when fully bolted.

    Honestly can’t believe my car held together all this time and I had no idea it was even broken at first. Car never had a sudden loss of power so I feel strongly that it was sold to me in this condition but just wasn’t burning as much oil yet.

    I just filed my piston rings last night, I think you might be a little aggressive on your ring gaps LMAO
