My 1992 GTI

Hey, if you plastigauged it and you dont see any scratches and its round I wouldnt worry about it.

[DocWalt]

Yeah, true. Would still be nice to have a bottom end ready to drop in at any given time lol. Probably a ~$350 project to have a rebuilt spare bottom end.

What is this stuff? This is in my old 2.0 head's exhaust ports.

Carbon deposits, simple green works well on it

[DocWalt]

White fuzzy stuff is carbon deposits?

[R/T93]

Its friable.

Could be burned up coolant??

[DocWalt]

Doubt it's coolant, it wasn't burning any AFAIK. All of the cylinders had the same amount of carbon buildup.

[DocWalt]

vrooom, vrooom.

[FeaRpb]

Sounds really good.

[DocWalt]

Thanks!

I've been beating the hell out of it after driving ~100 miles taking it easy to ease into the bearings. Seems to be taking the abuse, still nervous any time I hear a weird noise or rattle. Of course the car vibrates and rattles right at the same RPMs the rod knock was most noticeable before.
