Engine cleaning for city/condo dwellers

[Hendo]

I have my dad's old '82 Diesel wagon that I'd like to turn into a daily driver.

The injector pump is leaking, and the engine compartment is a mess.

In the old days, I'd use Gunk engine degreaser and a hose at the curb. But nowadays that isn't possible; I live in a condo and that sort of thing is prohibited.

Sad but true.

Any other suggestions for a DIY engine wash that doesn't require a hose? I used the l local coin-op carwash once and the high-pressure water created all manner of trouble.

Second.. I've read a bit about the wiring that Volvo used in the eighties is deteriorating. Would an engine wash make any of that worse?

I want to clean it up enough to get a good handle on where the leaks are coming from...

Thanks!
