any differences between mk1 and mk2 1.6l IDI engine?

[2mAn]

i was checking out an 85 golf diesel at the junkyard and noticed that the intake manifold had round ports whereas my '84 motor has rectangular ports. the newer manifold also had a better design for the PCV. i want to go back and pick it up but im not sure if this will make any difference? also what about the cam? were the mk2 NA diesels also rated at 52hp? TIA

I don't really know if the manifold will fit in a mk1 as it was designed for the mk2 chassis. As for it being better I can't really say. The biggest difference in the MK2's was the advent of hydraulic lifters. If it is still solid lifter then it is doubtful that the cam is any different, but if it is hydraulic then the base circle of the cam is different and it will not work.

the intakes are different, the later ones are shorter I believe, other than that the motor itself, and the exhaust manifold is all the same. If it's a hydraulic motor then woohoo! no valve adjustments for you, but still the same basic motor, just dont mount a hyd head on a mach block or vice versa and youll be ok.

the motor mount by the injection pump is different. you can switch it over though no problems.

opps, forgot about that... good call... Fundamentally tho, not including the accesories or mounts, the engine's bosses and fitment is identical

so were ALL the 1.6 NA diesels rated at 52hp?

The 1.

 I think that that is a brilliant idea.

Is that post just an advertisement for online gambling?

Yep, apparently he's an automated spam bot (check his other posts).

How about the injection pumps?  I have a MKII 1.6NA engine with the hydraulic lifters, and I was trying to buy the fuel line with the banjo fittings on it to connect to the injection pump.  The catalog only had this line for '85 and earlier.  Maybe I have an earlier injection pump on there?  I know it's not the original injection pump.

Actually, I think all of the engine mounts are different.  My MKII rabbit has a three point mounting system with one behind the engine on the left, one on the rear of the transmission on the right, and one by the starter motor.

The '81 rabbit has a four point system with one on the left end of engine, on on the right end of the tranny, a different one by the starter, and one on the back of the engine/tranny joint I think?  Not sure about that fourth one, I'd have to go outside and look again.

The engine blocks are both the same, just the mounts are different.

Your mk2 is not a rabbit at all, it is a golf, and they use a completely differnt mount system than the mki's like your 81 rabbit. All that said the mount are interchangeable on each engine.

I know.  To be correct, the '81 rabbit is a golf too.  As I understand, they were never called rabbit's in Europe, even back in 1974 when introduced.  That name was just used for the US MK1's.   I like the name rabbit better than golf (reminds me of the game, which I despise), so I use rabbit.

Yes you are right technically rabbits are golf 1's but I like rabbit as a name as well. Golf sounds lame.

I wonder if the different name was an attempt to convince the US market used to V8 detroit steel that the 52 HP diesel had more pickup than it actually did.  The Passat was called the Dasher here to begin with too.

Personally I find the 52 HP to be plenty driveable, unless you are on hills on the highway.  Then I'd like a TDI...
