JerseyDrew's 2016 GTI S build, a.k.a. Jersey Devil

[JerseyDrew77]

Hol up, wtf are we talking about again? Are we talking about adding an additional bearing to the rotating assembly, or replacing the oem thrust bearing with something else?

And also, what is it supposed to prevent?

We are talking about the OEM thrust bearings on the crankshaft and finding a solution that prevents crank walk. As you know, the shape of the OEM thrust bearings only go 180* with a single groove and since they don't have full face axial bearings in the crank like the 1.8T engines do, some people are getting crank walk. Why others aren't getting crank walk like myself still remains a mystery. Supposedly some have modified them as seen in the picture below...

Molded journal holders to make room for an additional bearing:
Bottom - 1.8T original
Middle - 2.0 TFSI original
Top - 2.0 TFSI molded for an extra axial bearing from a 1.8T

Would you have anymore pics and sizes?

 

[The Dude]

Ok, now I'm on board.

Of what?

Of what?

The journal holders above?

The journal holders above?

Those are not mine so I do not have any additional pics. I pulled it from Google which got it from this forum.

Slowly but surely everything is coming along nice with the engine build. I should have my car back by the end of next week and once I do, the break-in process will begin. That has to happen before I can even get it re-tuned by Ed.

Had a set of brand new OEM fuel injectors arrive the other day. There was nothing wrong with the ones already on my car. Just wanted to replace them since the old ones have slightly over 82K miles on them.

Still on track to get her back soon?

So far. I should be getting another update sometime today.

 

[JerseyDrew77]

Here's what my OEM thrust washers look like. Not too bad for over 82K miles and the abuse I have given my car.

And my OEM intake valves (the ones on the right) didn't have that much carbon build-up on them...

 

[The Dude]

you've got some incomplete combustion going on in cyl 4. Or I guess it might be cylinder 1. the rear most set of exhaust valves.

That was blowby from his bad piston rings.

ah, which predicated the build. gotcha.

So I won't be getting my car back this week. My mechanic has been slammed with work so he's running a little behind but I should be getting it back sometime next week. The block has been cleaned off and the pistons and rods were installed yesterday.

And I just love the look of the MAHLE pistons with a ceramic coat!
