My 1973 VW bus has this mount and has a factory air conditioning unit. Is this common or usual. No one seems to know.

I can’t see the photo, but AC was never factory equipment. It was put on by the dealer. My bus had AC and two other T4 engines I have were set up with AC. So it’s not super common, nor is it rare though.

Hey all didn't want to create a new thread so I hope adding to this one will be ok. I had my 1.8 short block rebuilt with 93mm 1.8 Porsche 914/ VW Type 4 Bus Piston & Cylinder Kit and a SCAT C25 Cam at the machine shop. This is my 1st VW engine I have worked on to this degree so sorry if these are stupid questions, just want to get it right the 1st time.

I am at the point of replacing the lifters with the EMPI 98-8625-B - TYPE 2/4 SOLID LIFTERS (Machine Shop Provided). My questions are 1) is this a good option for that Cam ? 2) they said the original push rods would be ok to use, does that sound like a good option? If not what are the recommendations? Thanks in advance.

Weren’t the 1970 Porsche 914’s the first vehicles to use the fuel injected Type4 engines in 1.7 liter size?

I have a 73 bus, ordered to Los Angeles with a type 4 1700. It has the smog fan and the exhaust heat pull. Looks identical to you picture shown, I’ll upload some pictures, prior owners did a very good job of maintaining it.

Can anybody tell me what this little “box” is and what is supposed to hook up
To it.

That’s the crankcase vent. Original setup would have a hose running to it from either the center air box with carbs or a hose coming from the S boot with fuel injection.

Seeing you have a center mount Progressive carb, do you not have a plastic port coming from the intake? A hose should run from intake port to breather box. If you leave that box open, it can, make a mess in the engine bay.

There is a plastic port on the bottom of the carb just below where the air filter is. So there should be a hose from the vent to the carb? Thanks

if the plastic port connects to the intake manifold or under the butterfly no. If the plastic port connects to the carb above the butterfly yes.

Yes it connects about the butterfly. Thanks
