Coolant loss- any connection to a fuel injector

Ah, but also a measurement of compressors capacity is pressure, so that’s air volume/time unit (normally one minute), that would end up at apx 4.5 bar/65 PSI (minute volume). Correct? That’s good enough.

 

Most people who are cleaning the coolers are first using some kind of solvent, then blowing it out with a pressure washer before finally spraying air to make the passages completely dry. Merv and many others have used wires to disengage the carbonized dust from the passages. To date I have not found a wire that works for me.

In the used JDM cooler I bought from ebay, every little passage has a slanted metal plate inside it dividing the the passage into two triangles. I do not know if that's the standard design but it makes it harder to insert wires in there. I will report back once I receive my brand new cooler today.

 

Yep, I am aware and also considered this. But as soon as you add liquid to this ash it’s much harder to blow out (with air).

 

The cooler can be clogged with a hard sticky material if the engine is burning oil. Otherwise it is fine. A good gen3 engine will show no observable oil loss in 5k miles. An oil burner can be fixed with pistons and rings demonstrated thousands of times under warranty.

A wire chucked on a drill does work on the serious sticky oil residue.

 

Can you provide the gauge or example of the type of wire you used for this purpose? A link would be very helpful.

 

A good G3 engine will therefore not have oily residue in the EGR cooler.

 

Guess I’m an outlier: dipstick never budges, and when I clean the EGR valve, cooler, pipe and the intake manifold (twice now), the “ash” is closer to anthracite coal, lol.

 

My 2012 Two has 142.5K miles. I bought it just a little over 1K miles ago. So far, my oil level has not dropped any at all and I am hoping the streak continues.

 

Yeah, until partway through model year 2014, they’ve got low tension piston rings. Kinda like being born with a heart defect.
