Aircooled Hut UK Service Information

So you have your new engine and want to ensure its lasts a long time? 

First thing is fill with a suitable oil! PLEASE DO NOT FORGET THIS STEP! 

There are many brands of oil good for classic cars and aircooled vehicles, my prefered oil is Halso for aircooled engines.  This has the right amount of zinc to protect the camshaft and followers. There are plenty of classic oils available that also contain zinc (ZDDP) but many dont state how much so please be wary when choosing. It must have the all important ZDDP additive which will save your camshaft from a very early cam failure!

There are plenty of web pages giving full information on this.

Short blocks and long blocks:     Steps    1-7

Turn key engines:    Steps    3-7

1/ Fill with oil:

Fill with oil as above to fill line and allow engine to turn over without a spark (remove centre distributor lead will do the trick)  it should pretty quickly get oil pressure and your dash light will go out. if it doesn't you may need to prime any external oil filter or cooler you have.

2/ Oil pressure:

Once you have oil pressure re-fit the distributor lead and you can allow it to fire up. Run it for a short time listening carefully for anything strange. if you hear something thats not normal, turn off and investigate!


3/ Listen:

If all sounds ok allow to run for 10 minutes, drain oil and re-fill to full line. leave over night to ensure completely cold and check/set valve clearances. Check/set points, timing. 

4/ 100 miles:

Drive steady for 100 miles, then change the oil and check valve clearances again. 

5/  500 miles:

Then drive another 500 miles, then change the oil and check valve clearances again. Check/set points, timing. 

6/ Usual servicing:

Now you can change the oil and check valve clearances at your usual intervals, remembering to check/set points, timing. clean/replace oil strainer or ext. oil filter. plus everything else thats needed with an old air-cooled vehicle.

7/  Drive steady and look after your engine and enjoy a long engine life. ;)

Remember, these are old engines even if made with all new parts, they are nothing like a modern engine. They need regular servicing, let them warm up before driving, drive steady and they will last that bit longer.

I go to great lengths to build engines with no oil leaks at all but, sometimes there may be the odd drip that I cannot be  covered under warranty. I will always do what I can though to help.


Enjoy your new engine in your VW!
