Another Engine Rebuild Thread - 80 3.0L
Well, my "spare" engine was delivered this week. I was so excited that I took off of work today in order to get started.
I bought an engine out of a 80 SC that needs to be rebuilt. I did this so that I could take my time with the rebuild while still enjoying my 82 SC. Once I am done I will swap the rebuilt engine into my 82 and use the CIS from my 82. Right now I don't have an engine stand - hence the engine sitting on a pallet. This is my first rebuild - I am a complete novice so I hope that this turns out well and inpires others to do the same when their engines are in need of a rebuild. Below are pics from today's progress. I am at a stopping point until I get a stand - can't take off exhaust without it.

Subscribing for information.
Good luck with your project. I'll be interested to know if there are any issues with fitting a 82 CIS on a 80 engine.

The 80 engine was supposed to have an external Voltage Regulator. When I pulled the alternator out yesterday it had the internal Volatage Regulator. Is it common for people to switch from external VR to internal VR?

I managed to get the cat and muffler off even though the engine is still on the floor.
This allowed me to remove the lower valve cover gaskets and the chain covers. The great news is that I found no broken or pulled head studs! Keep in mind that I have limited info on this motor other than the fact that cylinder #3 has zero compression with 100% leakage and the other five have 140-160 compression and poor leakdown numbers (don't have specific numbers though). Also, I took a closer look at the alternator today. I think it is pretty new based on the exterior condition. It looks like it was just put in. The fan housing has many cracks and the fan has a handful of chips. Here are more pics from today. Did I mention that this is the most fun I have had in a long long time? I restored an old house a few years ago and the demolition is always fun - same applies here. I am sure the good times will come to an end once I have to start cleaning and shelling out duckets.

Subscribed - What did you pay for the engine? - If you don't mind. Do you know how recently the engine was run?
The oil cooler is easy pickings while on the pallet - if you have a long enough extension. But get it up higher and save your back - keep having fun.

I think the internal voltage regulator is a good thing!
Looks like some yellow overspray from a car being painted? And, even maybe some primer, but what is that on the cylinder cover plates? Rust or dirt? Wow! You have gotten down to the meat fast and should have answers to the question about cylinder three (3) soon as to the leakdown numbers being bad there. I'm betting/hoping it just needs a re-ring or maybe valve guides. Also, it appears you are in the same boat I am with the 1978 3.0L having to use the crowfoot to remove cams, right?

Forgot to mention earlier that I think you have the Carrera pressure-fed tensioners in there already by the looks of it. If so, that is excellent and shows someone really cared about the engine's life-span.

Don't know how recently the engine was run but I am pretty positive it was within the last 6 months. Quote:
There is no rust (I thought same thing when it was coming off of the truck). It is red clay and grease! It does have the updated tensioners but I may use the ones off of my current engine b/c they are only 10k miles old.

Looking forward to rebuilding my 80 3.0 in a couple years, but this makes me want to drop it and tear it apart right now! |

It will be pretty cool to be able to say that you rebuilt a Porsche engine during your lifetime. That might seem sort of materialistic in terms of one's lifetime goals - but it is cool nonetheless!

I have an 80SC as well, I found a few broken head studs this past summer, so I'm going to be dropping and rebuilding once the weather becomes nicer around my parts. Man, it's been a long winter! I already purchased the engine stand and Yoke.. I've already decided to buy Race Ware head studs and I'll probably get a set of JE pistons. Hopefully my Cylinders are ok! I'll be posting pictures as well once i get started, keep your pic's coming, it's great to see them!

UPDATE:
Got engine stand this week. I managed to get some work buddies to lift the engine onto the stand on Friday - bought everyone lunch for helping. It was a little hairy at first b/c one of the buddies was a girl. I made a lot of progress today. Pics will follow next week as I don't have my camera connection cord here at home. SOOO ... a couple of interesting items to mention. 1) I have Mahle cylinders! 2) The cylinders were already scribed with numbers.  The scribed numbers on the cylinders were not visible until I pulled each cylinder. I only did 1-3 today (stuck on right side trying to get cam woodruf key out!). Does this mean that the engine has been opened up before?

Hi MCA,
Do you have the engine on the stand yet? Let me know if you need a hand. I'm not that far away.

Yep, got it on stand yesterday and continued the tear down.
Thanks for offering to lend a hand. I really think that I will need help during assembly. Also, I have to drop the engine out of my 82 and insert the rebuilt engine ... that would be a great time to stop by!

Alright Flash Man you are doing exactly what I have in mind. Buying a engine in need of rebuild before I need to do my own. You mentioned OK. Did you purchase from OK foreign or an individual?
Keeps those pics coming
