I think I can see cracks in the circled areas. Or mayby I'm just overly cautious because so many heads are cracked

Well the fuel pipe bending was not so easy. I spent most of yesterday with them and both pipes had to be scrapped. Today I took usable sections of the scrap and I made some models which hopefully will be a little help when I try to bend the full lenght piping again.


This section was very hard to do.

Turbo coolant feed required a slide hammer to pull out.

Aluminum parts ready to be sent out for vapor blasting.

Then it was time to start with the fuel lines.

It is going to be tight with the AN fittings at the back but there is just enough room.

Crank journals don't look too bad

Head has small crack in two cylinders. What would you guys recommend doing with this? My target hp is 500.

Then is was time to start measuring

This table shows the cylinder deviation from 81.00mm. Some ovality and taper. Pistons were all worn 0.04mm from stock dimensions, so the block will need a rebore and new pistons.

I had a friend come by for the weekend and we spent some time in the garage. He also had proper camera on his phone so a couple of good quality pictures for a change

This tank heat shield was rusted away so I got new one from Tradition. It's meant for B5 chassis so it needed some modification. Here it's being primed.

Shiny bores with no visible hone marks

Fifth main bearing has a deep groove in the middle. Luckily the crank was ok. Sixth bearing also has clearly visible wear on the coating (top halves are not in order in the pic)

Conrod bearings also have some wear on them

Stonechip and underbody protection sprayed, that's the chassis underside pretty much completed

I have to order one shield from tradition and paint the main fuel tank support before I can start fitting the tank. After that I will be making some fuel lines and brake lines. The engine also needs to be taken apart and measured.

08800 sprayed and seam sealer applied. I didn't make much effort to make the sealer look nice. I just laid down a bead and leveled with finger. I've seen guys at the Bad Obsession Motorsport (Project Binky) to wipe all the excess sealer off with a wet rag and it makes super smooth looking seams.

Next the wheel arches will receive stone chip coating and the rest underbody protection.

Sikagard 6470 is what I have

[Nuvo]

Man i'd love to give my my car this treatment some day.
Can you confirm that is Sikagard 6470 and not 6440 you're using there? It's difficult to see clearly in the above pic.

Bought myself all the things needed for the underside. New chassis bungs weren't exactly cheap from Audi


20240905_171030.jpg


All the cavities were waxed


20240906_185040.jpg

After that all the bungs were put back in. Hopefully tomorrow I can spray the 3M 08800

Nice. Well done

[Antsa]

Bit of a milestone today, underside has epoxy primer on. Looks much better now

Thank you sir! Sometimes it feels that a little less dedication would finish this project someday
