I follow the Vanagon threads. The Subaru motors use are not exactly bullet proof and bring their own issues to the table.

From what I understand this has been going on a lot longer than you think. <br>
With the quality of t-4 engine parts getting harder to find, using multiple<br>
sets <br>
of parts (while increasing costs) has been the way to go. Like you said, <br>
CHECK EVERYTHING. This is why Jake got out, quality engine parts were <br>
drying up. It's hard to guarantee anything when you can't get good parts,<br>
let <br>
alone back it. It's also why so many are going with a Subaru engine, as the <br>
quality of Japanese parts is much better than Chinese parts.<br>

<br>
Moral of the story is CHECK EVERYTHING, even stuff you've never checked<br>
before and read the forums, there is always someone else that has been thru<br>
the same thing and the builders will play games to get engines they have to<br>
stand behind. Ive heard Raby will mix and match bearing sets to get things<br>
to his standards, but at $80 a pop, I cant do that!<br>

Sorry for all the issues you have encountered. I have never seen anyone have<br>
as many issues with Type 4 rebuild as you have experienced. I am following<br>
the thread.<br>

Personally, I'd contact Steve (Clatter) on the Samba in the type 3 forum, as<br>
he's really a type 4 engine guy with a lot of experience with type 4 engines<br>
(has enough parts laying around to build a couple if needed in his engine<br>
room). You wouldn't have anything to loose but some time, and getting a<br>
second opinion from someone with experience never hurts. He even built a<br>
"sweep the floor" engine (showed the build up on STF) that went into his bus<br>
that he took the family on vacation with. He pointed out some things that<br>
not many people know about when building it that made some sense, and some<br>
of it could be thought of as off the wall. He does have a tendency to ramble<br>
on at times, but that's how he thinks at times. While we might talk to<br>
ourselves, he types it out in messages. He's also building a really nice,<br>
very well executed 67 Fastback with a t-4 in it. Give him a shout, maybe he<br>
can help.Bob 65 Notch w/sunroof<br>

<br>
Ok, Im getting Cranky!<br>
<br>
<br>
<br>
The crank that was in my 2056 was a 10 under, thats fine, but for some<br>
reason despite my measuring .003 to .0035 main bearing clearances, it<br>
started<br>
<br>
to sieze when it got warmed up with the break in oil in there, what is<br>
additionally interesting is that the sacrificial bearing shells didnt do<br>
their work very well,<br>
<br>
you can run your fingernail across the journals and feel some light scoring.<br>
<br>
<br>
<br>
The crank for this build is my spare, its seen alot of use and despite<br>
having 2 rod journals shells well into the copper the machine shop found it<br>
in the middle of the<br>
<br>
spec and just polished it, and it does, and did look good, except... the new<br>
bearing shells on it are a bit loose.<br>
<br>
<br>
<br>
These are old stock Repco bearings, and im finding between .0045 for the<br>
split one to .005 for 1 and 3. Now im measuring this with a mic and bore<br>
gauge, using the mic's<br>
<br>
measurement for journal size as the 0 point for the bore gauge, so it should<br>
be accurate. Bearings all torqued into the case.<br>
<br>
<br>
<br>
SO...<br>
<br>
<br>
<br>
im kinda porked... the wear limit is .006 or so, so I should be around .002<br>
or 3, and the bearings are what the bearings are, the crank SHOULD be in<br>
spec, if the shop measured it properly<br>
<br>
and since they have better equipment that I do....<br>
<br>
Should I have it taken down 10? well.. they say its in spec NOW... and 10<br>
under didnt do wonders for the hardness layer on the last crank and since 2L<br>
Porsche cranks dont grow on trees... risk it<br>
<br>
or run the .005 with the stock journals and stock hardness layer intact?<br>
after the incident with the break in oil im inclined to keep things on the<br>
loose side of ideal but past builds have had<br>
<br>
oil pressure issues so its sensitive to that, although the previous build<br>
had NO pressure issues.<br>
<br>
<br>
<br>
What to do? What are people finding the main bearing clearances to be out<br>
there in stock size land? they are sending me a set of silverlines to try,<br>
but they arent the quality of the Repco's.<br>
