Well I have a 74 bus.Its a pop top camper.The motor wont start now and makes a loud knocking noise inside.Compression is 1=140 2=130 3=80 4 =50 so it doesnt even have compression to start.Its a leaking plenty of oil too.So what I want to know is ...has anyone put a diesel motor in a bay ?Is there any bays that came diesel stock?Im looking to put a diesel motor in it, so if anyone can help me out its greatly appreciated .Thanks.

Anything can be done, but to turn a bay into a diesel would be a major engineering and fabrication feat or a hack.

Bays never came with diesels.

A water cooled vanagon makes a much better diesel project than a bay. Diesel engines were an option on vanagons.

Ohh I c so what about that vanagon motor in the bay?well maybe no I dont want to make the bay watercooled.So what should I go with just another type iv motor ?I want some more power for all my camping and diving gear.

How much $$ you got to spend?

It would be cheapest to fix what you have.

Get those dual carbs rebuilt while you are doing it.

The type4 engine is actually a great platform for more power. The most popular is the camper special. Here are a few threads on it.

My understanding is that this engine will work best if you use a later 091 transaxle.[/quote]

Fixing what I have involves taking the whole motor apart just to figure what it is , i wanted to just do a swap.Im not sure on the budget yet.Maybe I should just start taking it apart.

You could buy a rebuilt engine and swap it in. You could also buy a used one to put in also. You run the risk of being where you're at now if you do this and don't hear the engine run before buying it. I say rip yours down and see what's up. May be something that can be fixed easily.

Good luck

Thanks for the replys... im still debating on what to do.I would gain some more knowledge on ripping it apart rather than just throwing another one in.

So how much should I be looking to spend on a used type IV ?

I'm with you on your first idea. Put a diesel in it. Yes, it will take some engineering. Somebody else has done this. His name is David Schwarz.
His website is:http://motorheads.net/vw/turbobus/
Pretty well thought out.
Using a 1.6 turbo diesel has some advantages. good fuel economy. Simple engine. Electrical control is 1 WIRE!
This setup SHOULD get about 30-32mpg.
Read David's website. He is a sharp guy.
You could fix the type 4 engine. and fix it. and put a lot of gas in it.
