Hello ALL!,

I am going to start a series of rebuilding at least one of my ebay engines. Please understand that it will be a slow process, but would love feedback on what I do correct or suggestions on how to do better.

I am not going to talk too much about tear-down. Only the build process.

I now have heads ready for the machine shop, so I will start here.

It will take some time, but hopefully I will learn and help others during the process.

Anyone with VANOS H.P. pump knowledge? I need to learn and address before engine assembly complete.

Again, this will be a slow process, but expect to have a VERY nice engine/s when completed

I am very interested. I only have about 85,000 mi on my E60, but I have considered building a new motor on the side.
Hello Ltanderso,

It will be a slow process, but is moving forward.

Heads where cleaned b/4 sending to machine shop using a media blaster converted to soda medium.

Head are ready to send locally. Nothing special about heads and very durable. Will have them inspect, cut/grind valves and seats.

Blocks are my main concern. Sending to a shop on Monday. Do not expect to have a solution for at least two weeks.

Prep for valves was on using a cordless drill and grinder with mild steel brush to clean all scale, carbon, mud!

Some pics attached, but will take some time before posting new info!

Delivered heads to machine shop than has been GREAT with my Toyota/Yamaha 2ZZ-GE. When looking at head, I knew valve stem diameter was small, but the S85 is even smaller than the 2ZZ! They are ordering the valve-stem guide for machining the valve seats. Estimate 3 weeks for update on heads, but they will be NEW!

This shop also purchased a new cleaning/de-greasing system and informed me my heads would "clean-up". In my limited opinion of how heads are delivered to a machine shop, I thought they where damn near perfect and clean when delivered!

Very excited to get them back and see final result.
