Hello,

I have a 2015 Chevy Cruze 1.4T.

I was wondering, I removed my valve cover and found a lot of sludge.
Would it hurt anything for me to pour that cleaner on to the bearing caps and shafts to try and clean some of it out?
I used some carb cleaner, I have the drain plug out of the oil pan, and what I sprayed into some of the side ports (PVC area?), it seemed to drain out of the pan.
I guess I am wondering, will it seep into the cylinders and sit there, or will it drain out.

This all started as I went to change the turbo for the 2nd time in 8 months.
This turbo has the impeller frozen, could not move it.
I found very small metal chips in the PVC system to the intake.
I checked the intake and there is only a small part of the check valve dislodged laying in gunk in the port.
I have ordered a new intake, valve cover, and turbo.

Any feedback is appreciated.
Thank you.

theres an oil forum called "bob is the oil guy" the MMO question has been argued for years, mostly between "snake oil you dont need it" and "its a miracle product" ive used it before in my older cobalt, it did clean gunk out but i never had much to begin with.

Youll probably be fine running some short term.

Does MMO increase the engine destroying LSPI events?
Does it burn up and carbonize your turbo?
Will it evaporate and create intake build up on GI engines?

Who the **** knows??

Its a solvent so it will clean your engine...but will it cause long term damage? probably not.

if youve ordered and not installed the new parts, run some though for 500-1000 miles then dump it out and you should be fine.

I try not to buy abused engines in the first place, but when it happened:

I just put good oil in it and changed it more often until the engine was de-gooked.
But if that cleaner is less than $5, it'd be cheaper than motor oil.
