Marsmik REBUILD thread due to Spun bearing cyl #2

[Marsmik]

Yes.. I'm in the club!
Now I have to plan a rebuild.. but on a budget..
What do you think about this:

-CRANK:
mine is forged so i'm thinking to machine it
this is the actual situation:

- RODS:
at least 1 new if I stay with stock units
or
Spool forged rods (about 650$ on pmp)

Clevite bearings

- PISTONS:
Forged ROSS stock bore

- HEADS:
'99 lifters + check and clean at the machine shop

- BLOCK:
Nothing.. just a check and hone at the machine shop


120k tune up

adjustable cam gears.

Optional: 19t turbos.

Other: the car is not DD and partially gutted but in the next months it will be almost totally gutted.

About oil contamination is a New oil cooler, new oil pickup, everything cleaned sufficent for a perfect new engine or I miss something?

^ really man? Read what he said. He said budget not junkyard bare minimum. He has a forged crank to start, though I'm not a machinist so i cant tell you whether that is salvageable or not. But my guess is that after it's cleaned it will probably need over sized bearings, but i don't know for sure. I am one for doing in once and doing it right. So if you can afford the downtime, just save up and put whatever you want in the engine this time, so it doesn't have to come back out. A new oil cooler is a good idea, I've dealt with some non-car coolers that get metal in them and I think it's pretty well impossible to get all the shavings out. Probably get new lines too, Split Second has some kits that are pretty fairly priced. I'm sure you checked your oil pan for the infamous dent. Only other thing I can think of is maybe some poly or solid engine mounts while you'll have them off.

Good luck man! Glad you are saving her, don't forget to have fun with the rebuild!

When you spun the bearing, it is likely you deposited debris EVERYWHERE. You can try to clean the oil cooler, but MOST people would replace it. The single most important thing you need to do is clean all the oil passages and all oil lines super clean. Also check the turbos, many times the material from the spun bearing wipes out the turbo internals. You can resize the rod (or rods, depending on how many need it), but if you're putting in Ross pistons, I would recommend upgrading the rods as well. That would give you a nice, strong shortblock that should take whatever you throw at it. I also would suggest you make sure the balance shop balances the rotating assembly at 50%, not the 36% most of them use.

Steve, Nuff said'.
You need to stop thinking all cranks are cast. 93+ are forged. Not fiction but fact. I have 2 cranks here I can easily identify as cast and forged.

And what about the heads? Mine are in good shape. What they need during a rebuild of a 80K miles motor?

For no other reason than they are off the car, I'd consider a "fresh valve job" and new valve stem seals. Part of that process will inspect all the other areas "just in case". That way, 80K miles from now you shouldn't need to take a set of 160K miles off for rebuild. Just an opinion.

Update:
my rebuild will be a very slow process due to VERY little time available:

Transfer case rust.
Anyone knows if that is normal??
Look at the rust that came off and fall on the ground

And the clutch:
about 1500miles on it.
XTD stage 3 with little break in before some abuse.
What do you think about this strange wear?

That clutch doesn't seem too well...don't cheap out on the rebuild, it will cost you in the longrun...

Make sure the splines on the output shaft look like \_/ not \/ lol. Grease the tcase spool and the output shaft until you get them back together. Then read this thread: http://www.3sgto.org/f2/how-sh-t-cou...line-5449.html

Good luck on the rest of the rebuild
