Which Type 4 was the better one of the lot?
Thanks for your wisdom Fig.

The 2-litre is the most powerful and gives best fuel economy, but the 1700 and 1800 engines rev more freely (lighter pistons). A 72 bus should originally have had a 1600 type 1 engine or 1700 type 4 engine. The 1800 will work well in your bus.

According to the Mplate, it had a 1700 in, and according to one of the PO i looked up, it wasn't reliable, at all, he mentioned something about it dropping valves, or seats or something all the time... did about 2000km, in nearly 10 years.

Dropping valve seats is probably the main weakness of type 4 engines; this is almost inevitable on any type 4 engine that has run hot for any length of time. If the heads are properly rebuilt the problem can be solved.
Make sure that the engine is proplery tuned and maintained and has all its cowlings and tinwork and engine-to-body seals and a type 4 engine should be totally reliable.

I was planning on going to KKK when I still lived in PTA, earlier this year, and the the gearbox broke...
Took me long enough to finish it, tried selling the bus, nobody is interested. So now I am rigging it for overland tours.
