My turbo hates me, im about done with it

[Throwback23]

I bought this supposed e16g a while back only to find out it wasn't an EVO 16g..it had .004 thrust play so I rebuilt it with a trader Greg kit...a couple thousand miles later it was rubbing on the housing...thrust play was back...that's with OEM head feed and return.. so i put my old turbo back in no issues at all. I decided to give it another run and rebuilt it again, same Greg kit, New compressor wheel and turbine shaft ...this time I used an OEM return with a stainless feed from the ofh with a .079 restrictor. We'll like 75 miles in have a preceptable amount of thrust play that although minimal I would say feels like the.002 that is maximum allowed or worst case .001 more ill have to gets dial indicator tommorow and check for sure. It just lows my mind that my setup works perfect on my bep 57 trim shaft play but develops play so fast on the 16g...I can't explain it, my buddies e16g is on the same exact setup but is solid with not even that much thrust play...I also have a 14b sitting that is solid without any preceptble thrust over 100k on it ... Any ideas I'm about at the point where its getting old so I'm ready to cut my losses, thanks!

I used to run conv 15/40 rotella but there is no reason at all to run a 15/40 for me. The 5/40 has all the characteristics i need and lubrication is obviously better on cold start ups. Ive read all the bobistheoilguy stuff and i followed that montra in choosing the oil i run. T6 is very cost effective too. This is turning into another oil thread tho and im guilty.

OP: Either you are using wrong rebuild kits, the turbo is junk or maybe some small chance mobile1 is wrecking your turbo, though i find that incredibly hard to believe. Maybe send it off to Justin

We'll I tried to use a digital caliper and wow, talk about ghetto are us ... Mixed results but for now I got .0015 and .002. I'll get the dial indicator later today but was antsy to figure this out...

I'm pretty sure I have the steel thrust bearing in my 16g and I got it from Justin after blowing my 16g a few times and it being the thrust bearing each time! Maybe Justin can chime in again and clear this up?

Dang I need to switch oil after reading that!. However, my evo has always had mobile one syn and the turbo has zero play with over 100k on it. hmm?

I don't know, Mobile 1 never gave me any issues, however I wish I could see that PDF again, silly work firewalls.




I guess it doesn't matter when your car has I'm-gonna-sh1t-all-the-oil-out problems.

x7000 +1. My car doesn't like oil. I think it's allergic or something, or maybe I have one of those rare JDM EXTERNAL lubricating motors? Murphy's oil laws. If it can find a way out, it will!

Well I just got done with the dial indicator test and wow that was fun....way too much space to work with ...anyways the best readings I could get indicated that I had roughly.0018 of play...do I trust that's 100% accurate, not at all due to the jank little seup I had , fitting pliers ect in there but its close. I'm thinking I'm gonna change oils run it until it while monitoring play moving forward and be ready to pull it whenever the time calls. It's crazy how small that is yet you can still feel it just checking by hand and even more alarming how fast that developed... anyways here are the pics of the test resuls ..

So I went with valvoline nsl 20-50 synthetic. It was most easily available oil on that list, I suppose well see what happens next.

So just under 1000miles in and the play hasn't increased much but I'm still going to put an upgraded thrust bearing in with a larger collar and two oil holes... My question is can the oil seals be reused when i install the new thrust? I've always had a rebuild kit so this has never been an issue..thanks for the input

Since you have had nothing but bad luck, I would replace them just for peace of mind.
