Opinions on my water jacket....

Greetings from Boston. A4 Sophomore here.

1) I did some cleanup on my water jacket today. There was scaling around the water inlet fitting that concerned me. Also searching archives.

After gentle cleaning here is what I see around the threads.

This looks serviceable to me though I will replace short hoses and all clamps. Should I try to get another thread turn on this water inlet fitting? I did not see any leaks last season yet it is not as clean as I would like. Thoughts?


2) Likewise I wanted to check the bolts and margin around the plate. Only light scaling in most places. Here is what it generally looks like.

The worst bolt is below the main water inlet. Even this does not look bad to me. https://photos.app.goo.gl/7x6Jn8ua8VZ3uSvt6
I have seen much worse in the threads, still, wonder if any case to be made for Moyer studs at this time?

3) The tube sticking out from the block is my greatest concern. (Engine Block Drain Tube?) The base looks questionable, I brushed very gently. Did not dare wiggle. Again, noticed no leakages during last season.

Thoughts? Should I attempt to remove and replace. Likely will need to drill out and tap probably will break at base? Experience?

Thankful for reflections and guidance.

Scaling protection, aside from hoses and clamps, I plan a thorough brush down and paint in place. I may remove the water jacket to inspect for buildup or passage blockage, I have no temperature problems so I might just do a muratic acid flush. This is a bypass valve, no thermostat engine.


Thankful in advance. Stay well. Tim
