I would recommend holding onto those stock bearings in good condition until the engine is together and running - seems it can be a challenge to find suitable aftermarket quality.

Amstaff 06-30-2014 10:13 AM

I am not throwing anything away until the build is complete. Everything that I have removed has been bagged and tagged.

What is wrong with the bearings offered by our host?

Concern about quality of Glyco rod bearings

There has been a lot of recent discussion on the Forum about the quality of Glyco rod bearings. Seems to be a new development where standards have fallen off.
Look for this thread which has good photos.

Glyco rod bearing wear

How may miles had your 3.0L motor done? Amazing engines for a sports car!

And how did your crank measure up - do you have any grooves from oil seal wear?

Amstaff 06-30-2014 04:03 PM

Supposedly it was a 65,000 mile roll over.

I haven't done anything with the crank yet.

There are no grooves at all from the seals

Amstaff 07-03-2014 04:33 PM

Tomorrow, pressure wash and completely clean engine. Look for before and after pix.

After pictures
 
I used an old dryer brush used to clean lint from a dryer to clean out all of the holes. It worked like a champ. I then pressure washed and scrubbed with a Scotch Bright with some dish liquid. It came out ok but I will follow up with some long Q-tips to reach those out of the way places.http://forums.pelicanparts.com/uploa...1404485915.jpg

Next step
 
So, a bit more cleaning of the block. Once I am happy with it I will install new main bearings. Since I don't own the tools needed to measure the crank and the bearings I will use plasti-gauge. Some homework is needed to see how thus is done so time for some reading.

If anyone has done this and can share their experience please chime in.

Used plastigage many times over the years. There are no tricks, really, to using it. Everything has to be completely dry and clean (no oil on crank journals), and you have to ensure that you don't turn the crank or you will smear the little plastigage rope. Make sure that there aren't any burrs or nicks on the main bearing webs or any of the machined surfaces before you assemble.

Amstaff 07-04-2014 10:49 AM

I have used it in the past too but not on a Porsche engine where the case is the cap. Do I have to torque the entire case down to do it or just the bolts that surround the mains?

RedCoupe 07-04-2014 12:53 PM

Amstaff, good question! Perhaps someone who has done many Porsche engine builds has tried it both with and without the perimeter bolts. My sense is that you will get good readings with just the main through bolts torqued, but maybe somebody knows differently.

Pistons and cylinders
 
Well, today was piston and cylinder day. I bought walnut shell blast and used my handy dandy blasting cabinet and cleaned them. They weren't really bad so they came clean pretty quickly. Once cleaned I scrubbed them with dish liquid and a scrub brush. When I cleaned the pistons I pulled all of rings off, cleaned the ring groove, inspected the rings and reinstalled them. I still have to tear down, inspect and clean the heads and then I will empty the cabinet of the walnut and change to sand to do the hard parts.http://forums.pelicanparts.com/uploa...1405267667.jpg

I decided to have the rods done so they will be sent out sometime in the near future.

Next weekend, heads!

Rods
 
Well, I know this is kind of slow but I pulled all of the rods and bagged them with the old bearings and the wrist pins. Now to find a shop to recondition them.

Crank
 
The crank is now bare of rods. The journals look good. For my own reference as the crank stands up with all of the rods pointing at me the numbers on the rods are on the right hand side.

http://forums.pelicanparts.com/uploa...1406243775.jpg

The crank will also make it to the shop for a checkup.

I hear good things about JB Racing in Tavares. I will start there.

Ooo - I can help with that one...

I checked the rods and mains with Plastigage

Feel free to comment on the above thread if you have any recommendations to assist the instructions/process.

Good luck,

Cleaning and more cleaning
 
Well, I figured out why a rebuild at a shop is so expensive. It takes a ton of hours just to clean everything!

Today I got a few pieces cleaned up but there is still a lot to go.http://forums.pelicanparts.com/uploa...1406392498.jpg

Shroud repaint
 
The shroud got a good repaint today. I used Krylon engine paint which I have used before. It works great and sticks like glue
