Default 2nd Issue with my China charger

Hate to be the bearer of bad news but......



I already checked for shaft play and there isn't any and I can't make it touch the housing. So.....

wow, that stinks

So if there is no shaft play, then we're hearing bearings?

Guess it's time to test the warranty...

Edit: were you running restricted oil?

No I wasn't, not until last night at least.

Sounds like the bearings went dry. Any chance the restriction cut oil completely?

Wasn't running a restrictor until last night. It's been making this noise for a few days.

I read at least once that some have had bearing tolerances so tight on the chinachargers that there was no shaft play new. Journal bearing turbos need some lateral shaft play- that's the tolerance needed for the oil. Did it have play when new?

I bet that's it. I bet the tolerance is so tight new that the bearing itself is creating oil starvation. My garrett, new as delivered from an authorized dealer had lateral shaft play, but not enough to touch the compressor housing. The tolerance was problem half the distance from the wheel/blade edge to the wall in an extreme-to-extreme shaft play test.

I suggest you take it to a turbo shop and ask them if its worth a fresh bearing or not.

I've already contacted the seller and emailed the the link to the youtube clip. I will wait for them to respond.

Mine has lateral play to it...enough to wiggle a little but not touch the side wall. BTW, I've been using a homemade restrictor from day one.

Why would you want less oil to get to a journal bearing?

Journal bearing turbos shouldn't need a restrictor unless you are running over 60 psi oil pressure.
