I am in Athol. No making fun... I worked on Westover for the past 12 years, so I know Chicopee well. Now I work on Fort Devens.

Is the number behind the heater hose stamped or painted?

Does this mean I am hooked? Picked up a 1975 1.8 in Southern, NH this afternoon. I figure these aren't going to get any easier to come by and this one with all of the fuel injection and computer was too tempting. Paid $1,200.00 which I feel is a good price for a donor motor if I ever want to build a big bore and keep the original motor stock.

[MSGGrunt]

On the red car the driver's side number is 919 as is the passenger's side. What does this tell me?

[MSGGrunt]

The '75 donor motor is serial number EC040741 and the painted numbers by the heater ducts is 920. I asked about the 914 it came out of, but the seller got the motor with some other parts and no information on the whole car.

thanks for that number @MSGGrunt .

that number is a number we don't have yet for a 75 914 1.8.

we had 918 and 920.

--

i'll explain what they are and how they work.

for 74 1.8s there were 4 numbers on USA cars.
604 = EC-B (49 states engine) without centre console.
(in other words it had a standard sump lid without oil temp sensor and wiring up to top of tins).
605 = EC-B with console. (had oil temp sensor sump lid and wiring).
606 = EC-A (california) without centre console.
607 = EC-A (cal) with console.

we also have a number for the 74 euro 1.8. 608 = ROW 1.8 without console.
609 is presumed to exist but not sighted in an example.

for 75.
this is what we have.
918 = EC-a (49 state) without centre console (standard sump lid).
920 = EC-a (49 state) with centre console. (oil temp sump lid).
these were from examples where we could identify the car/engine from emission sticker
and from whether it had a console or not.

if 75s follow a similar pattern as 74s there would be six numbers.
( say similar because another trap we discovered with 74 research is that the logic does not necessarily directly duplicate the next model year, its similar but not identical often).
i speculated the missing 4 numbers went something like this.
919 = EC-b (california) without centre console (standard lid).
921 = EC-b (california) with centre console.

and there would be two other numbers covering rest of world.

these could be 922 and 923.
it would make sense as the 2.0 L cars for 75 and 76 have 924 (49 states) and 925 (California). we don't know what a rest of world 75 had on it.

anyway, you have thrown up 919. thats a first. (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/beerchug.gif)
thanks for taking the trouble. @JeffBowlsby will be pleased to see this information.
if my theory is right, that 919 belongs to a 75 1.8 (calfornia) that originally came in a car that was not factory fitted with a centre console. centre console had a temp gauge.
but i could be wrong. its a theory until we get all the data.
with the 74s we connected specific numbers, with engines known to be original cars, to original factory build data (sales orders).

-------

what does the number mean?
lots of speculation from time to time over the years.

my own view is the numbers identify the precise spec of the engine so that the correct engine was fitted on the assembly line to the car according to the market it was ordered from.

the only differences in 74 USA engines was a very subtle difference in emission set up and the sump lid set up. the euro engines were very different - carbs not fuel injection and higher compression pistons.

the same thing happens in 75, although the emission set up difference was a little more pronounced - the cal cars had EGR.

the engines were built remotely at another VW plant, fully complete and stamped with their identifying number before being sent on to different VW plants where the different VW model cars were assembled.

all the different VW engines of that era have these three numeral code stamps on them.

-----

the additional I.O. stamp means "in order" or in german "in ordnung".

PS @MSGGrunt .

other data you can get off the engines you have is.

1) the emission sticker. white label with red writing. stuck on the top of the cast fan shroud housing. may or may not still be there. be either EPA conforming (49),
or California conforming.

2). the sump plate lid on the underside of the engine. this is not the lid with the drain bolt but the other lid closer to the fan shroud.

if either of the engines you have are original enough.
the 920 should have a sump lid with a temp sensor inbuilt?
the 919 should have a "flatish" lid? it has got a bump in it, but a temp sensor does not stick out.
thats if my theory is right based on limited data to date. (IMG:style_emoticons/default/beerchug.gif)

@MSGGrunt

went back and looked at your photos and comments earlier in thread.

looking at engine bay, evidence says its a california 1.8 (EC-a) engine.
you can see where the EGR has been cut off.
also has vac port on throttle body upstream of throttle plate which originally activated the EGR (its now hooked up to your distributor vac can).
would back up your information suggesting car is originally a californian car.

in its present condition its basically set up like a 74 EC-B engine (49 states).

also i see it does not have a console with temp gauge. and carpets sure look original to me (and in great condition too) and if it had had a console you would be able to tell. and it does not look like it.




here is what one looks like with the EGR.




49 state 75 1.8s did not have the EGR.
ran a plain hose from the oil filler cap crankcase breather to the intake air boot like 74s.
also did not have the vac port on the throttle body upstream of throttle plate if engine still has original throttle body. vac advance hose from distributor was just tucked under the intake plenum and left open.
a 49 state 75 1.8 basically is identical to a 74 californian 1.8.
more or less.

[MSGGrunt]

Thanks for all of the info and glad I could help fill in some blanks regarding engine numbering. The decal on the fan shroud does in fact mention EGR and that the motor is California compliant.

Additionally, no evidence of a center console, so that adds up. I thought the carpets looked original. Also, the cannister, I presume part of the EGR system, that sits atop the passenger's side of the motor, though not installed, was in a box of parts included with the sale of the car. So I think it would be a safe bet to say the car is in fact a California car. Does Porsche have records of where cars were shipped to by VIN?

I had a 1985 300CD Mercedes that I was able to track was imported through the port of Houston, Texas and then went on to Tink Wilkerson dealership in Colorado Spring. Knowing this kind of information on the 914 would just be a nice bit of the car's history.

@MSGGrunt

sometimes owners retain paperwork with the original showroom window "sticker".
that has all that information on it regarding original dealer/point of sale, regional distributor etc. or most of it.

if you don't have that in the paperwork that came with the car someone like @davep who is a member here might be able to help you. he can provide you with a full history of the car for a small fee. i believe he is able to provide more information than porsche with their certificate of authenticity. you could PM dave.

thanks for posting the emission sticker.

whats the sticker on your donor motor say?
am betting its only USEPA conforming?

(IMG:style_emoticons/default/beerchug.gif)

[MSGGrunt]

Sticker on spare motor is the same minus the California verbiage.

[MSGGrunt]

And these are the EGR parts that were included, but clearly removed at one point. Not sure they need to go back on or should they? I will at least keep them if I ever do want to return the motor back to 100% original.

the evap system with the charcoal can is worth reinstalling.
no performance deficit.
keeps those hydrocarbon molecules where they belong. (IMG:style_emoticons/default/biggrin.gif)
if you need any advice on how to hook up the hoses just ask around here.

you wouldn't put the EGR back on. (unless you are an originality geek with a highly original car (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/beer.gif) )
it involves the original exhaust system that went on the 75s.
its a sort of twin muffler/cat contortion job with a little fitting that connects the EGR on one of the pipes between mufflers. i think.
i own a 74 so not up on 75s in great detail.
but probably EGR was removed because muffler was replaced. and maybe heat exchangers too.
i've got a feeling original 75 exhaust systems became NLA.
i have read somewhere there might be repro systems more recently but that could be for the 2.0L rather than the 1.8.

be interesting to see what heat exchangers and muffler set up is on the car.
probably backdated to 74. which would be a good thing IMHO.

as to the way the throttle body has been connected to the advance can on the distributor thats also a good thing. you probably know how those dual vac cans work so doesn't need much explanation.

[wonkipop]

Sticker on spare motor is the same minus the California verbiage.

which says thats a 49 state motor and it probably originally came out of a 1.8 that was factory delivered with a console with the temp gauge.
when you eventually get to look at the underside i'll bet its got the little round lid plate with the protruding temp sensor. thats a good find because it will let you install a temp gauge to whichever engine you wish. might need a new sensor but at least you get the plate.

the guys around this website call it a taco plate. very american.
i am an aussie down in north antartica - i just call it a lid. (IMG:style_emoticons/default/biggrin.gif)

[MSGGrunt]

All good info. I kind of do like the center console, so having the taco off the donor motor may come in handy. I will snap a picture of the exhaust tomorrow when I have some light.

[MSGGrunt]

Further evidence. Dash has EGR and CAT warning lights.

[MSGGrunt]

Pictures of the exhaust. The muffler does not have the Cat, so I assume aftermarket? I assume the shrouds around the pipes are the heat exchangers?

[rhodyguy]

The plastic charcoal canisters are easy to refresh the charcoal. The metal ones? Not so much. Buy replacement charcoal in the pelletized form on line.

[wonkipop]

@MSGGrunt

you still have stock 1975 heat exchangers.
they have a single pipe outlet into the muffler each side.

muffler is not a 75 muffler.
its an aftermarket muffler in the style of the factory pre 75 that looks pretty damned good.

looks like you got bilstein shocks as well. nice.


here is some tech stuff that tells you why your probably would not want to hook up the EGR and stock muffler set up (assuming you could get one anyway?).






i have nothing against EGR. it does not impede performance or rob horsepower as some folks think. but you can see why a lot of owners would have stripped it off when faced with exhaust system replacement.


i can see the second sump lid i was talking about.
its the non temp sensor type as i speculated.
all data ties 919 to cal 75 1.8 without temp sensor lid and cabin gauge. (IMG:style_emoticons/default/beerchug.gif)




for plumbing up the can.
the hose diagrams for the 74 are here.
page 3 of this thread in originality section.

http://www.914world.com/bbs2/index.php?sho...57407&st=40

75 just had the can moved to beside the battery.
suspect reason for moving can was location of the EGR.
in 74 the can was on the back firewall above where the EGR was in 75.
you could go for mounting the can same as 74?
you will be looking for the small diam plastic breather hose that comes from the fuel tank up front. runs through centre tunnel of car and makes its way into the engine bay on the rhs with the fuel lines near the battery tray. hopefully all still there.

as rhody guy says. plastic not hard to get apart (which it is from your photos) there is plenty of info around on how to refill them. but it might be ok as is.

member @Van B has done it recently.

Enjoy driving the car for the coming summer. (IMG:style_emoticons/default/driving.gif)
looks like you got yourself a pretty sweet little rig.
they go around corners a lot better that the brit stuff of the same era.
in fact they still go better around corners than stuff of this era. (IMG:style_emoticons/default/biggrin.gif)

[Van B]

Yeah get the big carbon pellets from the pet store. I also replaced the foam disc with lawnmower air filter foam. Just cut a piece the same size and fit it in. In all its a pretty simple task and definitely stops the fumes.
