I would pull it down, give it all a good clean, and at least inspect the bearings and all that.

Looks like a good core, be a shame to suck all that goop and grit in there.

I salvaged a case , flywheel, crank and conrods from a 51 longblock engine like that. Smashed off the cylinders, used recycled heads , new pistons and cylinders.
Reused rocker assemblies, dumped pitted valve springs.
Half the camshaft gear had dissolved.

Used a parts washer I borrowed on that AS21 case. It had corrosion inside and outside but there was still enough metal for the sump gasket to seal.
Had to rebuild some places where the bolts clamping case halves had nothing to bear on .. JB Weld to the rescue.

Ran 30000 miles until a valve head fell off.. recycled heads..

I just tore apart 2 long blocks with water in them. In both cases there was mild to moderate corrosion. I definitely would not run that engine without a full teardown and inspection. If the case, crank, cam and rods look good, replace bearings, rings etc. and have peace of mind. The alternative is literally Russian roulette..

Looks like a good core. Pull it apart and see how she looks inside. From what I can see - good to go. :D

I'm in this camp. I've rebuilt more wet / stuck engines than I care to count. This one is just wet, not stuck and it's clean- ish inside.

The careful / cautious way to do it would be to tear it down and rebuild it. Then you're up against "supply chain issues" including stupid BS like "Where do I buy good 20/10 bearings?" and "Do you know anyone who does accurate line bores?" and the rest of the slide down a a slippery slope. Screw it! This thing is on its second life already 'cuz it's built on a Type 3 case. Maybe it has nine lives?

Comparing apples to oranges, my XS650 Yamahas came from Japan with big magnets on the oil drain plugs. They catch an alarming amount of metal. Machine shop chips can't be good for any engine but they're in there. Worst I've seen is a 1" long piece of compression ring on the magnet. Still has good and even compression on both cylinders. Maybe one of my wise ass riding buddies dropped it down the oil fill just to mess with me? :roll:

Cough, Cough, Bullshit!
Type 3 engines, are usually in great shape.

The car spends so much time broken down.
The engine never gets, worn beyond factory spec! Lol!

^ This may be the first time I have ever seen someone quote their own post, before the quoted post posted. 67, I see that as good as being the first time traveler. Pretty cool!

Really?!

Out of all the VWs we had in our family my sister's '71 Squareback was by far the most dependable. It had the most power and got the best fuel mileage too! It's the only one still in existence and if I were to pull it out of the hay shed today, put new tires and rubber brake hoses on it I would not be afraid to drive it anywhere!

I'm thinking it was more of a lighthearted joke oprn. Maybe I read it wrong. The 71 fuel injected square that I had briefly was a super clean engine, but that's because an injector went out and they parked it for 30 years and since it was an auto no one wanted it 😂

oprn Fri Oct 07, 2022 5:33 am

The only complaint was that every time we looked at the engine those Bakelite injector holders were broken. Didn't seem to effect how it ran but we got tired of buying new ones so I got a machinist buddy to make a set out of aluminum. End of problem!

This one has a stuck injector. Ultrasonic in b12 and all was good, fired right up. Other than feeling a touch under powered I actually really like the true automatic. Sold it to a young man who loved vws but had a prosthetic left leg so had to have an auto.

You're kinda, justifying my, Yes, Light "Hearted" joke. :D

We rebuilt the engine at 80K miles, it now has 130K on the car and it was taken out of service due to body rust issues. That was the only real problem we had with the car. Never replaced a single other item in the FI system not even the filter! My '71 SB on the other hand... I don't know if I can remember all the issues I had with it!
