1994 GTX-No Water Through Manifold!

[Darren]

I blew air through 3 lines coming off manifold and three ports off manifold.
No obstruction is apparent, tell tale only getting smoke no water.

The tell tale line on head has been capped off, no line going to it.
The only tell tale line is to the manifold.

This is on the garden hose.

Help!!!!! What Should I Do!!!

Water Through Manifold

Well I took the tuned exhaust pipe off manifold.
Layed the pipe on it's side and ran water through tell tail fitting and water comes through the front fitting and two wholes at mounting base where the water is supplied by the manifold.

So the tuned exhaust pipe is out of the question for problems.

I then thought that my quick connect T valve for flushing may not be delivering enough water.

With the pipe off I stuffed plastic bag into exhaust so that no water would run in.

I conected garden hose and put water to it.
No water would come through 2 supply holes in manifold.

I then blocked the other end of T Valve where water would normally run out the eexhaust in the back and I got water to the two holes that supply the tuned pipe!

I think it is a matter of not having enough water and will replace T valve tommorow and see if I am right.

I re assembled the pipe and hoses so it wont take long to figure it out!

I am not sure what your problem is but it sounds if you may have a clog. [maybe sand.] If you are lucky you may be able to reverse the two maine water lines runing to your engine and back flush your engine. I believe that this will work on the older engines It worked for me on my 657x which is close to the same as a 720 I do not know the size of your engine as it may be smaller than the two I had mentioned. I would not recomend leaving it in this state of reverse for long but I have read that some old engines run fine like that. Mine seem too but I did not leave it like that for long just long enough to back flush the system. This may or may not fix you problem so good luck. Robin :cheers:
