To further the discussion… You could order anything VW made anywhere in the world unless it was legally prohibitive. Out here in the "free country," we have laws regarding emissions and illumination that are whacky and different from the rest of the world. So you probably couldn't import a bus into the US with incorrect fog lamp actuation, wrong exhaust system, or superior H4 headlamp projection style. Other countries could import the Vanagon with a Type 1 engine, modified Type 3 cooling system, and dual carbs.  (And I paid for a client's smog retest because the shop thought the crankshaft pulley notch was 6° wide…)
But Italy apparently knows what's up; the Type 1 in a later engine compartment is a dream to work on. And the silver front turn signal lenses look sweet; amber bulbs in there?
See you on the road,

Yes that' s true, here in Italy it's common to find baywindow with type 1 engine, rarely you can find a type 4 2.0 engine.
I have a friend with a westfalia camper with original 2.0 engine, but here it's really rare |

Today it was a good day, i removed cylinders and heads.
Now i belive the pre owner, she told me that this truck worked really hard, on the mountains for many year, but now it's time to reuild everything for a new life
This side was really dirty
This side looks better
Push rods cataloged, like in the maual love this book
The flywheel nut was easy to remove, no problem, but for remouve the flywheel........
ok guys i know it's really huge this extractor, but it was the only one bigger enough for do this job 
And here we are
How can i block the cams followers before opening the engine?
On the book they said with springs, but i don't understand how
Now i have two questions:
First, why the crank pulley has a thread in this side?
What's made for?
Second question, i wil buy a new camshaft with more performance, i will use new stock 1.6 cylinder and pistons, original heads, but with a 4 into 1 exhaust and maybe dual carbs, any advice? |

To screw any stray oil back in to the engine, it was done by VW in place of a seal.

That's a slippery slope, change one thing and it needs 5 others changed too to work right, careful. I'm a big fan of factory correct matched components, nothing else runs as nice or works so flawlessly as the original German stuff.

ok now the thread has a sense
For the rest i know , i agree with you, the stock engine works perfectly for sure, but i love to modify , i'm addicted to |

Very good! I like it. She looks like a beauty. That 9ft (or however big it is) bed would be awesome.

From my phone so I can’t paste links... but do a web search for EMPI VW lifter clips/holders. They’re used to hold lifters in place during assembly, but they work equally well during controlled disassembly IF you get their pointy ends to index the oil ports in the sides of the lifters. I’ve always wanted to make a “magnet manifold” to hold all four without a doubt...
I love the puller!

to hold lifters cut two pieces of coat hanger about 6 inches long, bend them into a U and tweak the ends in towards each other. They will each hold two lifters together.
I have never needed a puller to remove a flywheel. Once the center gland bolt is removed they near fall off on their own. If a flywheel gets bent even a little life will be miserable.
The heads on that engine have been leaking, one really bad. They need to be flycut to clean them up.

Gary could correct me, but I learned those "threads" are properly called Labyrinth Windback Seal. If I recall correctly the General Electric LM2500 gas turbine prime mover uses this idea, which is where I first learned of them.
Like busdaddy notes, they return the oil back where it belongs. This is due to the pitch of the groove (not really a thread... if you look closely, the peaks of the groove are actually pretty flat, not to a point like a thread) being run backwards during the engine operation. So the oil is forced backwards.
Why not a replaceable seal?
Its been more than 25 years since I read about these, but as I recall the LM2500 used one because the location was very inaccessible, rather hot and under pressure.
Not sure why VW used the idea, but likely the same theme.

The "screw" of the pulley also acts as an air pump, keeping the crankcase supplied with fresh air, and driving out moisture through the breather tower.
I can only speculate here, but I have seen FAR more T4 engines with moisture buildup in their oil caps than T1 engines. Like, 10x more. So I think the case ventilation is more beneficial than a seal.
Lasts longer, too.

I suspect he means new original size tires on stock rims, running old ones would be crazy.
That's a cool truck, nice find!
I wonder if the rear gate has been changed, didn't those late trucks with the big tail lights have windows in the tail gate? |
My 71 single cab has the holes in the tail gate, so the tail lights can be seen with the gate down. 71 was the last year VW imported single and double cabs into the US. (pre chicken tax) after that who knows what VW did. But then again those holes were not on all years, so... |

It's time to clean everything, and check all the components, hope it's everything good, but the crankshaft looks good, the crankcase too.
I will change the camshaft but i have a 3 rivet type, can i change it with a 3 bolt?
want to change the camshaft cause the gear looks a little bit worn, where's the connection with the oil pump

Wow, that's a really used looking motor, measure everything very carefully.
You can use a flat faced cam (3 rivet) if you use a matching oil pump, that dished cam in there now allows it to use a longer (deeper) pump.

ok so if i understand well i need a new camshat 3bolt pattern with a new oil pump that fit in a 3 bolt camshaft type, ok.
Yes this motors works really really hard in the past |

I learned this is an “ oil slinger” but I like that name more

Ha ha! Touché!
But my goal on the '78 RHD DC was to make it more useful, not to preserve its originality.
For my Mexican '75 SC, the goal is to get as close to factory configuration as possible, since it is a special collector piece. I was envisioning this Italian '75 SC the same way. But of course, it's his truck.

I believe that the tall holes was an option, but have never seen original ones IRL. The Mexican '75 does not have them. The Irish '78 also did not have them. But it does now, thanks to Gerson at KlassicFab who added some to a new set of gates:
I am also very pleased to see the B-pillar-mounted side turn signals on your '75. I added the same to my '78 (see photo above). Do you think your are original equipment?
Please share with us your M-Code plate!
And I am keen to follow your engine rebuild, since that is exactly what my '75 SC needs.

Hi guys, here i am again, how are you hope is everything well with you.
With this corona virus, i was stopped for a long long time, but i never forget my blue single cab.
Unfortunately, i don't have my truck where i live, and with the lock down it was totally impossible work on my truck.
But im ready to start again.
So the crankcase was bored +0.5, the crankshaft polished, the conrods chekeds, and everything looks nice and new.
I'm really happy today, my first step was to put on the bearings, and for tomorow i'm planning to put on the conrods.
i made by myself an alluminum plate to hold the crankshaft in the vice, and it works well. |
