2.2 Performance options

As I hate to spend money like I can just print it.... cheap first.

*Do the cat delete and wrap it.
*Silicone hoses next as they are going to fail anyway.
*That would be the end of the mods until the egr ****s itself.

There are 3 hoses BUT there is a early and late 2.2, they have different hoses!

1. Still does same, just no Exhaust soot in there just oil mist.

2. Provent is a closed system. Just a filter in between breather and inlet.

What's the best place to get the turbo beanie?

The point of my question was that I would have thought that the real problems would come from the soot, hot gas, oil mixture clogging the manifold and particularly the intercooler.

Although clearly not particularly desirable, I thought that with an EGR delete, so only oil mist, (or more likely and problematically oil mist and condensation leading to oil emulsion), maybe the problem is less severe so less of benefit to fix. Obviously not zero benefit.

The gases from EGR (exhaust gas) go into the engine just before the intake.
The gases from the CCV (fumes coming from the internals of the engine) typically go into the intake before the turbo.
The combining of the EGR (dry sooty gas) and the CCV (wet oily fumes) happens at the intake (where the EGR joins) and creates the black gunky tar like product (so you wont get the tar product in the inter cooler)
Deleting one or the other will stop the tar like product being formed.
I generally say doing a EGR blank or software delete of the EGR is a better way to go.
But saying that, using an oil separator is prolly a cheaper option on newer vehicles that are going to require a remap to delete the egr function.
Oily mist going into an engine isnt an issue (nor actually is exhaust gas).
In theory deleting the egr (the exhaust gas) from the intake of the engine should increase power and economy.
But in general, very little difference is noticed, but it will run better, although combustion temperatures will increase.
keep in mind that a diesel engine does not compress an air/fuel mixture, it only compresses the air to create heat, so very little oxygen is require to function.

I doubt anyone will jump up with "yes bluh bluh will break the law"....

Its one of them jobs you need to unbolt the exhaust section yourself and take it to a exhaust centre, if asked, dunno its off grandpa's tractor or its off an offroad use only vehicle.
