would fiber glass or foil tape help to shield that line from heat better? it is possible for one to add more heat resistant material on top of the lame attempt from the manufacturer.

when i checked online, it doesnt show the part will fit my car? did they fix this issue on the 2017 cruze hatch?

Sorry to correct you but you ment pcv valve built in the valve cover.

I have a 2014 Chevy Sonic 1.4l turbo with 21,916 miles on it and I’m getting a oil smell with the heat on but I see no visible leaks, any ideas on what you think this could be? I do get the oil changed regularly with the recommended Dexos oil I’m at 8% oil life so I know I’m due on that. I did check the VVT solenoids and they seem fine no leaks there either.

Curious, why wouldn't GM just use a bigger engine instead of this shoddy turbo? I'm taking my 2015 Trax in for the 2nd time for turbo failure. I only have 25k miles on the vehicle so it's still new in that sense.

Craig Smith says:

easy,, dont buy one

Great video but I either missed something or you didn't show it. The end of the oil line that fits in with 2 oil seals on it ( the other end from the banjo bolt ) is held in with a small bolt????? I didn't see you take it out but I am guessing where it because you showed it when you put the new part in. Y like other commenters suggestion to change oil more often ( I always have with all my cars because it's still fairly cheap insurance against future issues. You say 5 k "mile oil" changes which I guess is 8000 kilometers which has been my oil change schedule and the oil service warning still shows over 35%. By the way how did the re-bent oil line hold up at the " non-banjo bolt hold up? I would think that changing the angle by bending it like you did might cause some "oil seepage"? My wife's Encore is a 2019 and you said yours is a 2016-17???? which is probably the same as the 2019. I also agree that some extra insulation on the line wouldn't be a bad idea and some " header wrap" over that part of the exhaust manifold, maybe even a small amount of holes drilled through the heat shield in that area. What this vehicle really needs is about 20-25 more horsepower and torque. I wonder if there's a DIY way to accomplish that without requiring a switch to higher octane fuel ( a liter of 87 octane is between $1.55-$179 Canadian dollar) up this way and 4 liters equal 1 US gallon so do the math. I find that this vehicle doesn't accelerate to badly but passing at highway speeds takes some planning as the engine is screaming away but the speedo is barely climbing at all. Strangely at about 2200 rpm doing 105 km/hr or 65 mph it will climb up a fairly steep hill with relative ease.

dont buy vehicles with small turbo 4cyls.

Olivia Lay says:

Would the leak be from either end of that line, if blocked?

Bob Handeltis says:

Lesson of the day,do not buy this garbage engine.

Blue 04 MX 5 says:

Just for that bloody drain plug alone GM should get a class action lawsuit. It's so small.

Arch Angel says:

Got one in the shop right now, pulled turbo to change all lines and oil cooler and found both the exhaust housing cracked and so much play in the turbine shaft that it has started to touch the housing. 66k miles
