The items listed above as possibly standing between this engine and plug& play status are not expensive. All the pieces may already be there on the engine and/or on the car. Once you get into these things and become knowledgeable yourself, they will become simple considerations.

One other item which may be in the way...is the clutch. There are early and late clutches, mainly differing in the throwout bearing. The early style throwout bearing in the trans mounts to notches in the ends of the throwout arms on the crossshaft with clips. These clips are either 'U' shaped, or have a complete circle at the bottom of the 'U'. The sides of the bearing have tube-like shapes which stick out that the clips fit into and which set in the notches in the ends of the arms. The clutch must have a flat circle in the center for the bearing to push on.

The other later style has a support sleeve that the bearing slides in and out on. The arms have rounded ends and the bearing has square shapes on the sides which have clips built into. The sleeve mounts to 3 studs around the trans input shaft. The clutch usually has bare fingers for the bearing to push on.

Some clutches come with a center disc for early style bearing which can be removed for later style bearing.

The clutch and the throwout bearing must match before you put the engine in.

If the engine has a large can 1-1/2" across to the left of and below the distributor it is probably an oil pressure sending unit for a gauge. There may be a smaller idiot light sending unit next to it or the idiot light unit may be by itself. SOMETHING should be in the 1/8" pipe hole in the case there.

If the engine has an external oil cooler/filter, the "full" mark on the dipstick becomes the "ADD" mark.

Thanks Richard. Ask and ye shall receive! Here are some picts from the back of my baja:













Here are some pictures of my motor:











I also have a Chirco Oil Pump For Spin On Filter 1970 & Earlier (Filter Not Included) [CPR115138] and a Chirco Air Intake Screen Chrome For Air Cooled VW Engines [CPR119106] that came with the motor but am not sure that they apply to this motor. Thoughts?

That was quick!

OK...Let's take this in order of the photos.

Your car has an external oil cooler and a filter as I described. This is plumbed a little odd. If the hoses that go up by the window are simply loose ends stuck up there to keep them out of the way, the filter and cooler were plumbed separately. Maybe one "Full Flow" from the pump and the other from the top of the block. Could work, but regular "full flow" is better in most respects. "Full Flow" is when the oil comes out of the pump and straight to the filter and cooler, then back to the oil galley in the block or back to the pump body. It's called that because ALL of the oil goes thru the filter and cooler. Out the top of the case and back is only about 1/3 of the oil flow.

When I plumb these oil lines, I like to use "Flare" fittings on the end of the hoses and male flare fittings to the block and pump. This makes it EZ to remove lines to pull the engine or do other service. Regular "barbed" fittings are a PITA.

The cooler has been banged by the top of the fan shroud. This is no big deal so far, but might cause a leak later.

This shows that your Type 1 gearbox has the late style throwout bearing which slides on a sleeve. The bearing should get wiped clean before installing the engine and a thin smear of white grease on the tip and splines of the input shaft.

tdubs-83 wrote:


The clutch cable has some sort of spacer on it. That says something is wrong. I would take it out of there. should be just the wingnut on the end of the cable.

The fuel line has 3/8 oil line on it. It SHOULD be 1/4" /6mm low pressure fuel hose. That may be a protective sleeve over smaller fuel hose.

Good looking engine. Nice and clean.

There is a coil on the fan shroud and another on the firewall. A spare is good. But the wires have to be swapped when the need arises and they need to be long enough for that.

The Weber/Holley Progressive carb can be good for fuel economy while giving good performance when the pedal is pushed. But they have a bad rep for offroad use. Mainly fuel bowl vent problems.

tdubs-83 wrote:


You have a 36hp fan shroud (aftermarket) with the doghouse cooler. This is all good. Nice powder coat. No hookups for an external filter or cooler here.

The clutch is the later style which will be perfect for that throwout bearing in the trans! The engine case has the top captive nut for use with a doghouse. No room for a wrench in there. So you use a wrench only on the bolt head from the trans side.

The fan intake screen you have will not fit this shroud unfortunately. I have made a screen using 1/4" hardware cloth for mine. It sometimes gets pretty full of weed and brush stuff.

Looks like this engine hasn't been run yet. A full flow oil system would have a different cover on the pump. (plate held on with 4-studs with nuts) Full flow oil return would be back to the oil pump cover, or the upper oil galley plug would be drilled out and threaded with a fitting for a hose.

2-wire alternator has an internal voltage regulator. Make sure the car is wired for this. If there is a regulator under the left side of the back seat, it should be bypassed for this alternator. Not a big deal to do.

The white fitting on the aircleaner needs a 1/2" hose from the breather fitting by the oil filler cap.

You might want to trade that pump for one of these
www.cbperformance.com/...uctID=1875


That would allow you to hook up that oil cooler and filter.

Otherwise, the filter and cooler should be removed and set aside until you get the oil system set up for them. I consider them to be good, especially the filter. You might need to use a Fram HP-1 or Wix 51515R filter to keep from blowing it up due to high oil pressure on cold starts.

Richard, Man you are awesome. I appreciate you taking the time to reply lots of good information here. Almost as good as if you were right in my garage showing me all these things.

I do have a couple questions/comments on some things that you mentioned.

Quote::

It's called that because ALL of the oil goes thru the filter and cooler. Out the top of the case and back is only about 1/3 of the oil flow.

The engine that use to be on here had a turbo and the guy i got it from said that those hoses stuck behind the license plate went to the turbo. I had no idea what he was talking about since I have never messed with turbos.

Quote::

I intend to make this Baja my daily driver with occasional off roading. Will this carb do well for me? Do I need to upgrade? If I wanted something more aggressive what would you recommend?

Quote::

Can you elaborate on the fan intake screen? I just don't understand exactly what you are talking about and what I have to do to make it work.

Quote::

This engine has ran 20 mins on an engine stand in a shop. It is full of oil though.

Quote::

Would this be to replace the plate with the pump you recommended?

Again thanks for your assistance.

A turbo needs a lot of oil flow to cool it and keep the bearings from roasting from exhaust heat. So it was plumbed for that. So you will need to replumb the hoses a little.
Routing for fullflow without the turbo will be:
- from the pump to the filter inlet
- from the filter outlet to the top inlet of the cooler
- from the lower outlet of the cooler to the block inlet or pump inlet

The carb may work just fine for you. I say don't replace it unless it causes trouble.

Next step in carb would be dual Kadron with Kaddie Shack offroad float bowl vent. Next up from that would probably be a single Weber 40IDF or EMPI 40HPMX (essentially the same carb).

Ya gotta look real close to see the screen.


The screen for the Non-doghouse shroud will NOT fit on the doghouse shroud. Mine is made of 1/4" screen from a hardware store.

The pump I linked to is made for full flow with return through the pump cover and body. To install this sort of pump. you remove the existing pump entirely and replace it with one of these. For a "conventional" full flow system, the regular pump is used, but the outlet port of the pump body gets tapped and a plug threaded into the port. Then the pump is installed as usual but with a cover for full flow. In that case, the oil galley must be drilled and tapped for the return.

Now...Keep in mind that while I recommend a full flow oil system with a filter and an external oil cooler, this setup is definitely NOT necessary to operate the car. You could remove the cooler and filter from the firewall and bolt the engine in as it is. It would work fine.

There are more details and a world of more things for you to learn. I'm trying to keep it simple for you at this early stage and not overwhelm you with info you don't HAVE to know just yet. We can feed that out to you as you go. One doesn't have to pass his board exams for brain surgery before putting on their 1st bandaid. But it is good to know a little about cleaning and drying a minor cut and how to install a bandaid 1st.

Honestly I am loving every word that you are responding with. I started to work a little on my bug after work today. I already took the filter and cooler off the fire wall, replaced the fuel line and some other interior items. I have the grease and I feel that I am ready to bolt on the motor.

I do have some more electrical questions. Is the coil and the alternator the only items on the motor that need to be connected? I also found the regulator.



Is that only used for the alternator or are there other items that are connected to it as well. If I need to bypass it for the alternator then can I remove it all together?

That same applies whether the car had a generator before or had an external regulator alternator.

So is there a way to get a baja registered as a 1965 model? I live in Pinal County where I didn't have to get emmisions before. Well apparently now the ADEQ has decided to make some parts of the City of Maricopa require emmissions testing and lucky me, I fall in that region. So I was trying to get my baja titled and registered today and I was only able to get the title since I now have to get emmissions before I can register the baja. Totally wish my pan was a '65.

Can anyone tell me why this wire from the coil is connected to the carb? Looks like a sensor or something.

POC is right. That wire powers the electric choke. The carb end needs some insulation because it's so close to the fan shroud. It has power whenever the ignition is on. There is no fuse on that circuit, so if it shorts, it can burn the car down. The factory wiring diagram shows the ignition wire coming from the 1st fuse at the end of the fuse panel. But the ignition wire comes from the power side of the fuse, not the fuse protected side.

A piece of shrink sleeve available in the automotive wiring at parts stores and WalMart would do fine.

Please excuse my ignorance. I am not an engine guy. I plan to learn as I go and become pretty knowlegable but at the moment I am not that close. So as you can see from my previous posts I was trying to intall my motor. Well I was successful at getting her started and she runs pretty good. I have been doing some fuel economy calcs and honestly they are horrible. I esimate about 13 mpg. Seriously ridiculous. I feel I don't have the right combo with the engine and carb or have a bad carb altogether but honestly have no idea why it is so low. It is supposed to be a 1776 cc and in my last bug I had a 1600 with well over 30 mpg. I wouldn't think that moving up to a 1776 would produce that bad of fuel economy. Possibly my odometer is not accurate but it doesn't seem as if my tank lasts that long. Any ideas?
