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

Cylinder 2

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.. :?

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€ :|

Hi, any progress on the engine rebuild? Mine is similar spec 3.0 V6 12V year 91. Did you manage to get decent used pistons?

No progress on engine rebuild :( All used pistons are garbage. All way bellow under specs. Also A class liners to get, impossible. So rare stuff!

I don't have any other option, then buy new set of C class pistons for 600€ and then some used B class liners and bore them to proper diameter for pistons to have correct clearance.


Also update for what happened in meantime.

30 pistons and 22 liners and also got another 6 pistons. All for trash.

Image


Image

Image


Bought micrometer 0.01mm and measured all 30 pistons on 20°C.

Image

Image

The best two! :lol: :roll:

Image

Image


About car. Disassembling continuous. No rust so far.

Image


After that I took a break from pistons and liner and star cleaning block.

Answer from Jim K. But problem is. That I don't manage to get even to 0.100 clearance :lol:

Image


156 dreaming about V6 :lol:

Image


Second day of cleaning. Still not good. Engine gasket very "baked" on block and still few corners of dirt.

Image

Image

Image

Image

Image

Image



I am cleaning engine block with toothbrush, inox cleaning spirale and dish sponge (for parts where bearings come and liners). Hopefully I don't take any material from block with inox cleaning spirale. Because head gasket is very hard "baked" on block.
