 |
|
hey guys,
I know this has probably been brought up, and I have read it before , just tagged I am a bit confused when it Comes to identification of my engine case.
I have a H0636339 engine stamp on the alternator stand and a AS21 on the sides of the half cases on one end is AS 21 then below 043 101 101L while on the other half there is stamped WWO AS21 043 101 102G.
My distributor number is a 0 237 020 196 and below it 050 905 205A.
Could someone help me identify my engine parts, year of production and possible original displacement? Good quality, possible issues?
Thank you in advance |

There's something wrong here. The H0636339 number would have been from model year 1967. However, VW didn't start stamping AS21 on the cases until some time later. And the 043 part number series didn't begin until the middle of model year 1973. So I suspect you have a later block, perhaps a dealer replacement block, that got stamped with a previous serial number.
I'd like to see photos of that engine number. And the distributor too. |

Yeah, that's not a 1967 case, that serial number stamping was not done by the factory.
And the distributor, well I can't see the whole thing but I'm sure it's not something that will fit that engine case. |

The distributor has been working well. I suppose it is a modified VW Golf Distributor(Hall effect electronic ignition) from what the PO told me.
In addition, And idea what year the block is? Is it Dual or Single relief?
Finally , Timing, considering the distritor, what should i time it if i install dual carbs? |

Check the underside and see how many plugs there are covering the relief springs and pistons.
I agree it looks like a universal replacement case (note the Type 3 hanger bar holes) and a collection of parts that fit or were made to fit. Nothing wrong with that, but you may be on your own figuring out displacement and timing.
What heads are on it, dual port or single port?
If you still have it apart you can measure the stroke and bore.
Best guess would be 1600 since that became the most common set of replacement parts for air cooled VW engines.
As for ignition timing, it's a guess with that unit! I would start at TDC at idle with any hoses disconnected and plugged. That should let it start. Then I'd find the maximum advance you get at high engine rpm and full throttle (of course you have to be quick with this!), and keep it to about 30 degrees, maybe a bit more if you have a vacuum can on it.
More photos of the carb and engine top may help us, too.

The heads are single port and the carbs are weber ICTs..will have a look at the underside
Pistons are 1600cc..thus engine will be a 1600sp with an cb 2280 cam. |

| Okay, so it's a real Frankenengine! 1500s were single port, single relief, single carb engines. Clearly this is a retrofit with newer parts, perhaps number-matched for licensing or tax purposes somewhere along its history. Again, nothing wrong, but you now know you will have to be the engineer/mechanic here to put it together and tune it right. |

The heads are New Mexican single ports I got at a good price. Hehe, a real Frankenstein! . Cool, I will see..I still haven't had time to look at the bottom to confirm whether it is dual relief, work is crazy this time, but I can safely assume it is single relief or were there any AS21 dual reliefs? Considering it was a later block...thank you guys for all the advise |

| I’m having the same problem trying to figure out what year my engine is from. There are two sets on numbers stamped on the crank case both sides and a different number behind the timing belt. The charts I’ve been looking at tell me it’s 1972-1980 depending on the chart I look at. It’s confusing. |

| Hello all . New to the site and happy to be here. Recently purchased a 1962 reconstructed beetle Dune buggy. I’m already dressing it up exterior wise but I’m curious about the engine. Seems to have a serial number of U0242201. Am I correct to assume this is a 1970 TYPE 3 Super beetle 1600 cc engine? Based on the beetle 62 engine grids I’ve found I think it safe to say it’s not the original engine . I located a useful grid on apple tree that seems to say it’s a 1970 though so looking to see if one of the guru’s here can advise. |
