And for the end. I have calculated a little bit how much will rebuild of 3.0 V6 12V cost me. I was quite surprised! Maybe, maybe 1500€ will be enough. And this is with almost all work done by me and material with my business discounts.

But it will be like new! :D

Image

Image

Of course I didn't follow that strange order I, II, III...

Image

Image


Fun part. Some marks from some dried liquid. Very few scratches. But they were honed already, so..

Cylinder 1

Image


Cylinder 2

Image

Image

Image


Cylinder 3

Image

Image

Image

Image


Cylinder 4

Image

Image

Image


Cylinder 5

Image


Cylinder 6

Image

Looks like whole engine was took apart. And biuld very bad togethe. Who hones only cylinder and leaves old pistons rings? Look how much dirt oil ring has in it.. :?

Image

Pistons vere 5x B class and 1x A class.

I got them measured. Not results I wanted. This V6 will cost me some serious money! :evil: All fucked up, because people rebuilding engines without knowledge.

All cylinders honed to C class. Cylinder 2 had some serious problems, because it is very worn.

Pistons. I don't know why, maybe already because to much big clearance or because they have left old piston rings. Pistons are ever bellow A class. You can't see any worn marks on them, but they are fucked up. Measured 2 times, to be sure.

Clearance between cylinder and piston should be 0.050 in 0.069 mm according to manuals specs. And mine have clearance bewteen 0.112 to 0.244 mm :roll: :|


Image


Piston specs. Mine bellow any class.

Image


Cylinder specs. Mine are let's say so, C class.

Image


And clearance between both as it should be.

Image


Would you say by look, that this is fucked piston? I wouldn't...

Image


So now I am looking for other used set of pistons and cylinder, that will be within manual specs. I already found 7-8 sets (new and used). So something will probably be ok. Last option is new set pistons and cylinder, which is about 700-1000€ :|
