Engine...

[mcvw]

Hi,

I'm figuring I have some time on my hands until I find my "ultimate bay" so I'm considering freshening up the old 1600 twin-port that I held onto after we sold our old Danbury.

It's complete - apart from coil, dizzy, carb (the carb - or most of a carb + bits is in an old plastic washing up bowl) and exhaust.

The manifolds have been removed and the exposed orifices/ports on the heads were stuffed with some old rags by the prev owner (presumably to stop beasties and grime etc getting in).

The engine turns over on the flywheel, but there is some resistance before it completes a full turn.

So... For want of asking... Where do I start? Is there a quick way to tell if it's fooked?

All ideas/suggestions/help appreciated - I make a wicked cuppa if you fancy coming over and showing me the ropes

Thank you,


Mike

pull and push the crank pully. if you can wobble it about you may need the case line boring with oversized bearings etc

Think the end float is ok - doesn't seem much play - if any at all. But that might also be down to it being partially clogged up from being outside (but covered, and off the ground) for past few months :shock:

I think the resistance just before a full turn is normal, cos when i was adjusting my timing and valve clearances i had that!
Isn't it the pressure building up as the piston squeezes the air in the cylinder head?
If you take out the spark plugs it would stop that and then you should be able to turn it over and feel for tight spots or binding.

Yep, resistance is usual, mine feels practically seized at some points. :lol:

Personally I'd change the oil and plugs, borrow a carb, coil and dissy etc and try and fire her up on the bench/patio/floor/kitchen table. If it runs it runs, if it seizes then break it. (Or, weigh it in at the moment!)

Thanks guys - I'll take another look at it over the weekend.

Bit of thicko question... How do you fire up an engine on a bench? Do you still need a starter motor? :?:

Cheers,


Mike

yep...

an old bell housing and starter and your away

Hi,

Been a while - but actually made a start on checking out the engine today.

Here's the patient:

As you can see - he's been serviced at some stage and had a new "tag" put on. I believe this was official VW behaviour?

Checked the oil level at the dipstick - and it was just about registering on the stick.

Turned it over on the pulley (with a big socket) and after the first few turns it's turning over a lot more freely. You can also hear a squish type noise. Is this good (the compression stroke?)

Next up, I whipped the plugs out (they came out really nice - smooth as silk! And the plugs don't actually look in bad condition either.

The inlet ports for 1&2 were pretty well oxidised

but ports for 3&4 had none whatsoever.

Took the rocker covers off and both sides were black and shiny - with a few drips coming out. All rockers/valve train moved freely when the engine was turned over. Didn't appear to be any slack, but I never checked the valve gaps - will do next time.

Turning over with the plugs out, you can feel the air being pushed out by the cylinder, and you can even hear a kind of sucking noise on the intake - so I guess that's all good too?

So, should I be worried about the condition of the ports for 1&2? Does the head need to come off and be cleaned to remove the dust type residue? Or should I put a carb, distributor & coil on and try and fire her up?

Suffice to say, the engine is no longer outside and is now tucked away in the garage - and sat on top of a couple of old bug wheels.

Cheers,


Mike
