that white milkshake stuff is water in the oil....

Fill the cylinders with penetrating oil, put the transmission in forward, and get a pipe wrench on the drive shaft coupling. I think you'll get it started, I'm just worried about the rod and main bearings.

[rockhopper]

From what I can see the internal gears look really great. I have Evapo-rust sitting in the piston cylinders. I'm some what concerned about trying to remove the block from the oil pan due to the rust/corrosion on the side of the engine the starter is on. Also I bench tested my Delco starter, the pinion gear comes out but does not spin.

[Ken Rockwell]

the starter might work if you break it free with a wrench. You definitely need to hone the cylinders. The oil pan bolts are pretty bad but you can easily heat the threads from the top. You could also grind the heads off, then separate the oil pan and grab what's left of the shank with a pipe wrench.

Haven't seen this asked or addressed yet: Do you have the Moyer Manual? Gotta get it if you don't.

P.S. - based on my experience hauling and rebuilding my engine, and reading the stories of several other A4 owners (I'm looking at you, Dave Neptune), I'd say that engine is most likely saveable.

[rockhopper]

Yep, done had my hands on the service and overhaul manual. That was the first thing I got when I realized I was going to have to yank the engine.

[rockhopper]

Well I got the reversing gear pulled out and all but one bolt out of the starter side of the oil pan. Going to have to grind the head off due to the restricted space between the bolt and the oil pan flange, my channel locks just won't grab enough to pull it loose even after heating it to a nice cherry red. Going to try my best to get the block and oil pan separated when I get off work today.

[rockhopper]

Well I got everything tore down last night. The pistons knocked out of the cylinders easy with a piece of 2x4 and a 3lb sledge. Here is a link to the entire photo collection of anyone wants to see them. https://goo.gl/photos/JsGTUpy2tZVA1F419

Nice job. Have you ever seated valves with a cordless drill?

Nice job. Have you ever seated valves with a cordless drill?

No, the Mercedes I replaced a head gasket on I seated them by hand I believe. Had a suction cup tool(forgot it's technical name) and valve grinding compound.

[Ken Rockwell]

First remove the lifters then slide the cam out. Get a drill with a screw bit. Also a rubber hose and two hose clamps. Hose clamp one end to the valve stem the other to the drill bit. I'm not sure if the rubber hose will fit through the lifter holes. Twenty seconds between checks.

"The Moyer Manual"

RockHopper, In this era of "fake news", the best advice I can give you would be to stick to the Moyer Manual regarding your rebuild.

I'm with Thatch. The ol' dop stick and valve compound works fine.

Have you found any cracks from freeze damage?
