So, I'm in a similar but different situation with my 3.0 motor.

It (very likely) has a bad valve guide on #2 because the exhaust side comp is like 90% leak down, basically running on 5 cyl when I pulled it, but all other leak down numbers are right where they should be.

Am I crazy for planning to yank the left carrier, try to pull only that cylinder and fix just that?

Engine has 167k on it, only 34k on top-end rebuild.

What barrels are you going to get? Same pistons?

Did you have alusil or nikasil?

Not crazy, that's what I would do.

I was literally planning to pull the one head off, have it fixed, and put it all back together. If I'm not going to pull the Ps/Cs why would that matter?

I'm not asking to be a wise arse, I'm being serious. Why not just fix what's broken instead of the toss cash at it just because approach...

Sorry-

Question was for original poster.

Your plan sounds good to to me :)

Nikasil. I will be putting the factory Mahle units on. I believe the new ones will also be Nikasil.

We my engine was apart I was real happy I went "all the way" because the intermediate shaft bearings had some significant wear. How was the shaft bearing on this engine?

Cool project to document. No doubt many of us would love to be there to get in your way and ask stupid questions and slow thing down. ;)

The intermediate shaft and bearings looked fabulous. I have not removed the rods from the crank yet. I am waiting for my crankshaft holder that I ordered from Stomski Racing. I should be getting back on it Friday. (my day off) I am going to take the case home and on Friday have it steam cleaned. That should save me a few hours of scrub time in the solvent tank. :)
The guys at the shop seem to think having this motor here is a "borrow parts" paradise. Fine by me since they replace what they took with new.

Im curious to see how you go with those Glyco bearings.. clearance wise...

Mike, I think Glyco has gotten a bad name for other reasons. We have used Glyco bearings in all of the engines we have built with the exception of customers supplying their own bearings. IE. Clevite, Jerry Woods. We have never once had an issue with them. (25+ years) I had a long conversation with Wrightwood Racing on this very issue. For you, and for my own curiosity I will use Plastigauge on the bearings and check. I usually verify part numbers and stampings, assemble, and see how the "feel" is. I'll go a step further for you. :)

Building these engines is not an easy task as you know. The sheer parts count is astounding!

I received my STOMSKI crankshaft holder today. What a piece of craftsmanship! Can't wait to use it Friday. BTW, Great customer service too. Steven Stomski, if You are following this thread, Thank you!
Pics to follow.

I am not getting too much done today. I took the rods off of the crank. One set of the bearings on #3 cylinder had some significant scratches on them. The rest of the bearings looked pretty good. The crank is being shipped off today to CCR to have it mag checked, cleaned out, and polished up.

I also dropped the engine case off at the local steam cleaners to have all the cracks and crevices cleaned. I need to go pick that up before they close.

The rods are going to German Precision to be done. I have two sets of 3.2/3.3 rods already done that I picked up today. Both have ARP rod bolts. One set is for this motor and the other set is for sale if anyone is interested in them.

Today is head stud removal day. I am replacing the original studs with all steel "Raceware" studs. The last stud (upper #3 nearest the flywheel end) is the worst one to remove.

Dang I shoulda stopped by. And I drove my 911 into Sunnyvale to have lunch today.

But I might get lucky and get to 200k miles before mine is due...

Things are moving right along. I have all of the case hardware cleaned and prepped for assembly. I also have the chain housings, chain covers, and oil pump cleaned and prepped for assembly. All of the galley plugs in the case and blind studs in the chain housings have been epoxied just as the factory does.

I have been sourcing parts that were missing from the motor here on Pelican.
I got word today that Armando from CCR shipped the crankshaft via FedEx. I am hoping to see it before the weekend. I had him cross drill it for better lubrication on cylinders #2 and #5.

I also heard back from the machinist, MTE, LLC, that the heads and cam towers are mostly done.

Hopefully if all the stars and moon line up, I will have it all by the weekend. If so, the build begins. More pictures to follow. :)

I need a clone...of me.

If you get all the parts by the weekend, you can spend Labor Day, laboring away!

Looking good dan! Got a buyer yet?!

Not that I know of. I have not even counted up the stack of receipts for parts yet. I'm afraid to. :eek:

I received the crankshaft back today. Looks great! I'll be starting assembly tomorrow. :D

very cool...
Im interested to find out if there is a alignment for the rods.. ie, does it matter which way around they are mounted on the crankshaft? (this might be a silly question!)

I started out the morning driving up to South San Francisco to drop off round two of the powder coating goodies. I got a much later start today then I wanted to but....OHWELL.

Mike, Plastigage was used this morning to check rod bearing clearances. 002" Very uniform crush all the way across.

As a general rule, I always keep all of the rod number stamps facing up. An old habit from my old VW days. These rods are semetrical and it does not really matter which way they go. Type one VW rods are asemetrical and they DO matter which way they are assembled.

I think that is enough progress for the day. I should be getting the heads and cam towers back from the machinist next week. The cylinder air deflectors are what I dropped off at the powder coaters this morning. I will need those back before I can put the heads on anyways. I will probably be working on the intake manifold assembly next. I am replacing all of the fuel lines and re-installing missing parts on that.

Another pithy quote that grabbed the spammers attention. :rolleyes:

STOP QUOTING SPAMMERS!!!!!

They hide images in their posts for tracking. When you quote them, you DOUBLE their tracking.

If you want to quote them, put spaces in their image URLs.

Friday was my running around day. Drove up to South San Francisco again to pick up the rest of the powder coated goodies. From there it was off to German Precision to glass bead all of the hardware that is going to be re-plated. I got to hang out with Ted and Jerry Woods for awhile. Jerry was making a tool for a 996 transmission. After getting all of the hardware stripped it was off to the plating shop then back here to work on the engine for a bit.
Today has been, or at least felt like I got something done. :D Heads are on, cams in, cam paralell alignment checked, rockers installed, valves pre-adjusted, and ready to set cam timing. I'll save that for tomorrow. I'm burnt.
