WOO-HOO!! It works! Thank-you!!

So if I want to add picture, I need to use the 'attachments' button and not 'insert image' button.

Now the next question... when do you use 'insert image' ?

Image inserted:



The URL I inserted was this, pointing to a jpg file:
http://www.bwsrh.com/images/800banner.jpg

Attachments can be in a variety of formats. URL's for images must point to files in an image format.

Ok, thank-you. I now understand the distinction, it needs to be web URL that directly references a files with an image format, because it does not upload.

Got a question on the coolant passages between the block and the head.

Excluding the oval coolant passageway at the edge of the block by the valves, there are 10 round coolant passage. However, looking at my head I only see 5 matching ports for coolant.

I looked at the gasket on MM and the gaskets matches the block so someone thought about this. Is that something I need to worry about?

OK, just found this thread:

http://www.moyermarineforum.com/foru...ead.php?t=6805

i wonder if Bill T ever saw any different by drilling out the other 5 ports?

Well, the head is now back from the machine shop along with the manifold and few miscellaneous parts for cleaning. Total machine shop cost so far is $260 (including the crank work).

Ken and I had a long caucus today... but the Amish One have blessed my oil pump as being the on correct side of the bell curve of "good". So only the $83 testing fee.

... and the result of the caucus is I now have $2600ish of cool new parts heading my direction.

I'll post some pics of the painting tomorrow, with some suggestions.

Foreshadowing: think "etching primer"

I've asking questions in a few other threads, but now have all the parts back from the machine shop. I forgot how tedious taping and painting is, but mostly all done now.

Now to let the paint fully cure, in parallel I get to start putting pistons, rings, wrist pins and rods together.

Thanks!

With the other recent on-going 'bomb' threat, I did the only responsible thing... I painted it "Safety Red".

For the curious, attached are some of my notes I've been gleaming form the MMI overhaul manual plus thing to avoid. Pictures are stolen from Iloverust's overhaul thread... before the photos dropped offline. Drat!

Give me an example of a link to a missing image. I may be able to post a fix.

Bill--

Here you go, starting at post #38. Most of ILoveRust's post after that have a pics reference to a photobucket URL like:

These images were stored elsewhere, so they were never available inside the MMI forum. Maybe Rust can help?

Yep. We have now determined the picture posting via URL is fraught with danger (in the reliable space).

Let me ping ILikeRust to see if he still has the pictures. He sold his boat with an A4.

Progress has been slow, but yesterday I got all the valves lapped.

Thanks... but I cheated a bit and used one of these.

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

It's handy because of the mechanical twisting back & forth if you hold the gizmo stationary with the drill running. Then you just loosen your grip for a moment to let the valve rotate a bit then tighten your grip to shift to the back & forth motion for lapping.

7 of the valves came out perfect on the first pass. One didn't have a uniform surface, it looked like two fine parallel rings on the valve surface. That one I did did a second time for about 30-40 secs and it became just like the others.
I switched hands on that valve, so I must have provided consistent pressure.

Also, you need to dip the valve stem in oil to lube the guide during the process.

I do not call that cheat, I call that using the right tool for the job! I struggled with my old ones... your outcome looks just great!!

Installing the Oil Control Ring

Been away for a while, but need to finish up the engine. Crank is installed, the 3 oil internal oil plugs are in and now on to the piston assemblies. I'm looking at the new Hasting rings from MM and I'm puzzled on how to install the oil control ring.

The installation instructions from Hasting are for standard 3 piece spring spacer and an upper and lower ring. Since the A4 using a two piece spacer the spring leaves about an inch gap around the piston. With the T-shaped slot on the side does it matter where I leave the gap?

Any one have A4 specific installation instructions for these pesky rings?

Ok nevermind. Google and MMF saved me. I found a few posts from IlikeRust rebuild. No need to worry about the position.

OK, been making progress, but taking pics in the middle of assembly with the rather sticky Permatex assembly lube it just plain a PITA.

However, I did discover a good way to retain the connecting rod bolts during assembly, cheap ballpoint pen caps. They worked perfect and were thin enough to not hit the cylinder walls and rigid enough to help guide rod onto the crankshaft journal.

These are typical conference or hotel pens... and just break the pocket tab off the cap and you are good to go.
