Hi everyone, I've been quiet on the forum a while but my car is almost back with me after a full respray back to original colour. Before I took it to the garage I wasn't happy with the engine, used/leaked a lot of oil, not much power, and starting wasn't great. Last week I started it up at the garage and it ran like a pig, blowing crankcase fumes out and refusing to idle. So I was wondering if anyone had a spare OK engine lying around to fit a 46, or maybe decent top ends, (pistons, cylinders, valve gear) I even bid on the 66 that was on ebay yesterday thinking I could fit the Renault engine and have a bit more power. Did anyone on the group get it?
Hi, you wouldn't be able to fit a 66 engine to a 46. How long has the car been off the road? There is a good chance that if the engine has been idle for a while that the piston rings may have gummed in their grooves You could try pouring about an egg cupful of Redex in each cylinder,leave the engine for a few days then start the engine[it will produce loads of smoke].Let the engine run for a while,switch off and repeat the process with about half an egg cupful,leave a couple more days, start up and once most of the smoke has cleared some gentle revving for a few minutes.If gummed rings were the problem there should be an improvement. Also check that when you turn on the ignition there is a loudish click from the electromagnetic valve on the carburettor.Also check that all the vacuum pipes are in place particularly the main pipe from the inlet manifold on the back of the engine.

Very interesting. As Starider says, you can't fit a 66 engine into a 46! Completely different, not least of which your 46 is air-cooled and the 66s are water-cooled!
The DAF air-cooled engines are super little engines, generally accepted as being "over engineered" in many respects. If you really need a new engine or bits, there are people here and there who I'm sure will be able to help.
I have some Daf 44 & 46 parts, including a carburettor, to which you're welcome, if it would help. I also have some 44/46 brake parts. As to dealing with a seized engine, another method is to pour diesel in to the cylinders and leave it for a few days. It probably works in the same way as the Redex suggestion from Starider. but either way you ought to be able to free off any sticking rings. Keep the Forum informed as to your progress and JOIN THE DAF OWNERS CLUB if you haven't done so already!

As Andrew says diesel does work as a release agent, but re-starting the engine with diesel still present can be difficult where as Redex although smokey will enable the engine to fire up fairly easily[Redex is an upper cylinder lubricant and will also loosen any carbon on pistons,valves and cylinder head and to some degree the exhaust].
As mentioned already, the air cooled engine is a well made unit, I would be surprised if anything serious was wrong with it. They are really easy to work on, and all the bits are available. It is less than an hour to take it out of the car (I think 20 mins is doable for some people) :-) One forum member in particular (at least one) has lots of experience with that model, and I'm sure you will get even more good advice. If it comes to worst case senario, there are complete engines out there. Can't wait to see the little beaut.
I thought getting old would take much longer than it did.

Starider asked how long it has been off road. About the start of lockdown, so 3 months. I did check the oil level before starting it at the garage, and it seemed a bit overfull. Then when it was running I was getting oil being blown out from somewhere near the carb. It smelt a bit of petrol, so maybe the garage has been trying to start it on choke and the oil has been diluted. Sometime in the past my car has been fitted with an electric petrol pump which I guess is not standard, so maybe the float valve has let more petrol in than it should and diluted the oil?? In any case, I'm going to tow the car back home and renew the engine oil, check the compression and the float valve. Then try starting it again.
