Ready to start engine reassembly #1

Now the real fun begins, this is the part I reall enjoy about a full restoration. smiling smiley

Got the block,crank and cam back this weekend. Bore is +.020 and the crank came out nice at -.010 / -.010
Just had to do a light cut on the deck to true it up, and same on the head.
Recleaned all the oil passages with rifle brushes and boroscoped them and the water jackets today looking for any hidden gremlins. All looks good.
Will set the crank in tomorrow and start measuring bearing clearances.
If there is any intrest, I can take detail pictures of anything anyone needs while it's still apart.

Having never been through an engine re-build, or even seen one, I have a couple of questions that will surely show my ignorance. What is the orange coloring on the inside of the block? Rust preventative? Is there no chance it will ever come off (chip or peel) and get into places it's not supposed to be? How did you keep it off the machined/milled surfaces? Tape beforehand or polish it off afterwards?

Thanks for your time- Dave

Hi Dave,
It's a special paint called Glyptal made for this application.

http://www.eastwood.com/glyptal-red-brush-on-1-qt.html

Originally the blocks had a red sealer painted on probably before machining. I carefully paint around surfaces, but any overflow comes off with a solvent rag or scraping after drying with a razor blade.
By scrubbing with solvents, and soap,removing all oil before painting, it will stick and not come off after drying.
I've used it in engines, gearboxes, and differentials with no problems for years.

Thanks Dana-
Is that a process routinely used by competant "commercial" engine re-builders or is it something done by guys doing their own engines, trans.,etc? If I send my engine out is that something I should expect,or,have to specify probably at an extra cost?

Appreciate all input- Dave

Dave,
Not sure if commercial builders would take the time. Race engines, maybe, but figure you will pay $80+ per hour
for someone to do something you can do very easily. It is one of those things that pays for itself immediatly,
and you get the satisfaction of knowing its done right.
Something that doesn't show, but keeps corrosion at minimum inside engines that don't get used alot.

Am building a 1800 now and know your feeling of enjoyment when things are clean, new and go back together. Looks very nice.

No offense Dana, but I would hope one could find the product from other than Eastwood who IMHO are mostly always over priced.

Here's some info about the product. You do need to insure the motor is VERY clean...there are even some contrairian views about painting inside the engine...

Seems to be the season of the rebuild. My engine/tranny are out, body is stripped, I'll probably do the rebuild in the fall, so pictures would be great. Thanks, Rob 69C GT

Nice to have a good thread I could tag for when I finally get around to rebuilding mine. So definitely a well documented procedure with photos would be awesome.

Definitely looks a lot nicer than my engine...

Now that's looking very nice !

I've heard many pro and con about glyptol coating inside the block and head as an aid to oil flow.... Only talk though, as I have never heard or seen proof of the paint actually causing a problem. The theory of that smooth surface allowing for better oil drain back seems to make sense to me, but I have never tried it. I have always just cleaned up the insides and removed any casting flaws, then made sure everything was spotless.
Either way, that looks really nice and I'm sure you'll have a Very Nice motor when finished !

Hi Joe, like I stated earlier, I've used it for years with no problems, but like any paint, it's all in the prep.
Both MG and Jaguar use a red primer/sealer inside engines and iron case gearboxes. I don't see a need for faster
oil return, but do it to help prevent rust inside the block from moisture, which when mixed with oil makes a
perfect grinding compound to wear out your new, expensive parts! eye popping smiley

Be very careful when installing the new oil pressure relief valve if you are buying one? Making sure it is seated properly is something to double check to ensure it sits flush to the edge of the blocksurface and that it moves freely when pushinh on the plunger

As far as I know theoil pump vanes are getting to be a rarity as they are not made any more?? robert may correct meon this?

Dana,

Excellent "Pro" point !
Seriously, I think I will use it in my next build.

Yep. I bought a new one last year. Very expensive too. Simply put, it was not the correct size. It would not fit into the orifice !
I had to grind the flange to get it to fit. Plunger worked fine tho'.
The original slid in or out with just a little tap. I assume its just another case of poorly made spares.

With due respect to Richard, this is the first complaint I've heard about the replacement "rotor" for the oil pump which I do stock. It may be possible Richard got the 0.005 oversize replacement which are not being made anymore.

Robert I believe Richard was talking about the oil pressure relief valve.

Indeed I was speaking about the oil pump repair unit. But I also have never heard an issue with the valve...curious...pretty sure we all get them from the same origin.

Never used that paint inside the engine, never taken one apart with internal rust either.
