Hey gang. http://picasaweb.google.com/Mark.D.Zimm ... antProblem
has some pictures up of a leak on my engine coolant 'manifold'. A piece of 1/2NPT iron pipe takes water from the manifold to the heater pump mounted on the rear firewall and on into the passenger compartment. I had thought the pipe was loose, or that the tape around the threads had given way, but a half a turn with my hand confirmed worse. The pipe had rusted and broke off.
I've removed it, but ended up unable to remove the last half inch of the pipe still bonded to the hole. My thoughts are:
Run a tap inside the broken pipe and plug the hole with a bolt.
Invest in an easy out (which is a lie from what I recall) and pull the old pipe, replacing it with a 1/2" NPT plug. As a side question, can those be rented from the autoparts stores?
While I want to do the job in a fashion that I don't have to worry about further down the road, minimizing my expenses and efforts at this point are primary motivations. I have to do this tomorrow so I can get the bus out of my driveway and I'd really rather be working on the interior than farting with the motor more than I have to.
My next question is, do I really need to take off that manifold or can I do this with it still attached to the bus. How big of a deal are a few shavings in the wet side of the motor. There IS a filter after all.
Thanks in advance for any opinions.
