3.2 Carrera engine project (to be sold)

[syncroid]

I am going to tear the rest of the motor down tomorrow. Pictures to follow.
There has been no update because I was on vacation last week.
The sheet metal has been sent out to be powder coated and the tin behind bank 1 (cylinders 1-3) has been ordered. That will go out to the powder coater when it arrives. It's coming out of Germany. The tin that came with the motor was modified for SSI heat exchangers. That piece is being powder coated as well.
I will be sending the cooling fan, fan housing, strap, pulley, and shims out for refinishing tomorrow as well.
I received a brand new air filter assembly today from the dealer. The old one was broken.
Engine gasket set, main bearings, rod bearings, countershaft bearings, and timing chains have been ordered from Wrightwood Racing and should arrive possibly tomorrow.
Hopefully, time permitting, I will get the heads, cam towers, and barrels/pistons shipped off to the machine shop tomorrow as well. Also will be sending the cams off to be redone if necessary. Still going to wait to decide if I am going to put the stock 3.2 cams in or the 3.2 cams ground to 964 specs. I have both.

This motor would be perfect for my '78 Westy.......

I'm gonna enjoy this! Thanks

Looking good. Will be cool to see a master at work!

David, You need to clear your PM box. Just sent you one and it is full. > FYI

Thank you Sid!

Post some pics to FB along the way and I'll share it on my work account, lots of car guys on there!

Will do.

A new "On the Bench" series.. Cool! Subscribed!

Good progress today.

I was pleasantly surprised at the condition of the cams and valve train assembly. No pitting whatsoever! Also, the main bearings show virtually non-existent wear. I have not pulled the crank out of the block yet. I was kind of burned out today and wanted to call it a day. I did not get started on it until almost 1:00pm today. My morning was wasted running around doing other things.
I did not have time to get the machine work stuff sent out today but that is okay. It is all boxed up and ready to go out on Monday. The Wrightwood order showed up today. I'll photograph all of that when it starts to go back together.

I was serious Dan, shoot me a message on the $

Any chance you will be converting to EFI with ITB's for this build like Al K does?

Now that would be one very cool motor if you did!

Typo...meant to say like Al Ikosmal.

The PO posted Compression/Leakdown numbers in the original for sale post as follows:

cylinder 1- compression 170, leak down 26%
cylinder 6- compression 177, leak down 66%
cylinder 2- compression 179, leak down 13%
cylinder 4- compression 180, leak down 3%
cylinder 3- compression 180, leak down 12%
cylinder 5- compression 182, leak down 9%

Wondered if you made any conclusions during teardown as to the cause for the poor leakdown numbers on 1 & 6?

Internals look really nice for the mileage, told you Dan I loved on that motor really HARD (lots of RPM's) but always kept up with oil changes and bought stock in Rotella (Shell) lubricants.

Yes. The valve guides were absolutely wasted! Not abnormal for 3.2 engines. The barrels and pistons looked really good too. I'm going to send them out to the machinist and have them checked, cleaned and measured. I will probably put those up for sale when I know their condition. I want to put new Ps & Cs in.

I'll most likely keep it stock except for possibly putting the 964 spec cams in it. We will see how the funds are looking.

Mark, The internals look really nice. It was obvious that you did frequent oil changes on the motor. Good job!

Thanks for posting this info and taking a bit of the mystery out of purchasing a used engine and rebuilding it!

What can be done to mitigate the valve guide wear during the life of the engine?

If regular and proper maintained doesn't prevent the problem, how are you rebuilding it differently to avoid the same problem in the future on this motor?

The valve guide material is going to be different then what came in the motor originally. The new valve guide material is manganese/bronze.

I got the first round of sheet metal back from the powder coaters today. I'm still waiting for the piece coming from Germany, also going to have the cylinder air deflector tin coated.
