Re: good thing to clean out engine
 

That line is extremely important. It sucks off the engine fumes and
condensation from cold starts.

Without it the engine will fast fill with sludge and water and up and
die very soon.

You aren't talking using chemicals to clean sludge here, we are talking
putty knife and pressure washer....

Our 88 has 315K on it and I keep that line working. My engine still
only uses a liter of oil between changes...

Re: good thing to clean out engine
 

I tried getting a piece of hose to connect it to the box, but every size I
get is either too big or too small.
What size is yours?

That sounds like a personal question.

*ducks and runs*


The hose is a non-standard hard-line in the ZJ. You can either get one
from the dealership or use a slightly larger rubber hose and a couple
of band clamps. A little electrical tape or duct tape to build up the
connector might be required.
