911sc 3.0 Engine Rebuild

[Cat.p.j]

Hello,

I have recently embarked on rebuilding two 3.0sc engines. One is from a project car that went swimming in Katrina, and the other is an engine that my dad (loosecats registered user) purchased as a rebuilt engine. The seller of this "Rebuilt" engine failed to mention that it was a cosmetic rebuild only and it still had broken head studs.

I have read Wayne's engine rebuild book, and have decided to reuse the pistons/cylinders in a top end rebuild of the "Already Rebuilt" engine. There are signs that this engine has had a full rebuild in the past as the pistons/cylinders are already marked with which location they belong to. I am not sure why the previous rebuilder did not replace the stock dilivar head studs for more robust ones.

While removing the #6 wrist pin from the piston, I accidentally pushed the cylinder off the piston past the rings....

Is it still "Okay" to re-use these without much more than cleaning and re-assembly?

Also,
I am located in the Dallas Fort Worth area and am in need of a good machine shop to inspect/rebuild my heads.
Does anyone suggest someone in the area?

Thanks

Pull the cylinder off, its the only way to do it, then put it back together as a sub assembly after cleaning the ring grooves and cylinders.

I rebuilt a flood damaged 1993 3.2 a couple of years back. The car ran even though there was water in the oil. The problem was oil pressure. The oil pump looked like this:




Read the threads, they're downright corrosive!

ID this, for a slow $20

First time rebuilder gaining momentum!


And - disconnect the battery on any flood car ASAP to stop wiring corrosion until the car is dry and you can clean everything up!

I'll be following your rebuild with hopes for some graphic photos!

PJ,

What are you waiting for?

Just stop complaining about the fact that the last guy that rebuilt the engine didn't know what he was doing and get that engine rebuilt !!! LOL!

Just kidding ! hopefully you'll get some good responses from your inquiry.

Pops !

Flat6pac,

Thanks for the advise. I had actually made a tool to hold the cylinders and piston's at a maximum distance apart before I read your post....
I used some heat on the bottom of the piston's to ease the removal of the wrist pins, which was performed with a home-made slide hammer. (worked fairly well actually)

After all this I may still end up removing the pistons to perform a thorough cleaning of everything.

Don,

You posts are pretty cool. Your engine looked really good throughout.

Here is a picture of the flood engine:


Here is a picture of the "Rebuilt" engine:



The flood engine had all the exhaust side dilivar head studs broken, and a broken rocker arm! I assume it had a chain tensioner failure at some point and slipped timing as all pistons had a small nick in them from valve contact....ie: bent valves.

Here is a picture of the flood engine after I split the case:


It is going to be a long process!

Well,

The latest update on this project:

I was inspecting the pistons on the 2nd engine and found that the #2 piston was cracked. I am now thinking about building a 3.0 MFI engine similar to Jeff's which is described in the post below:

Another Successful Pelican Engine Build - My 3.0 Liter MFI Project

On this engine at least:

On the flood engine I had a few ideas and wanted to run them by on this post to get some constructive feedback.

1. I was thinking of sourcing a 3.2 crankshaft
2. for the P/C's I was thinking of the LN Engineering 100mm slip fit kit with JE piston's that is made for the 3.0/3.2 engines.
3. will the SC heads work with this setup and do I need to change the cams..(possible custom made cams???)

I was wondering if anyone has done this before, and if so what is needed to make this work.

Will the Cis system work with this setup?
What should the expected performance increase be for this setup?


Thanks

Philip
