• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

Offset water neck for use with DUI


New member
I'm looking for an offset water neck for use in my sii with a dui. Attached is a pic of the part I'm looking for.

I currently have the dui installed, but had to grind the locating peg off of the cap and rotate it 90deg due to clearance issues. I'd feel better with the offset neck and new cap that is positively located.

Have you called Jeff about this???

If he doesn't have one at his location, I have one I can supply from my location. He'll advise ya of the cost, I'll drop ship if needed.

But I have only one left that I'll part with at this time. And it will be very clean and ready to bolt on after painting.

what years did these come off of? May have a few!?Jeff
The waterneck applications are not a "model year" thing Jeff. It's use was based on engine application by platform...and an engine not equipped oem with an a.I.r. System (air injection).

Some were used in vehicles equipped with a vertical flow radiator, some were used in the transition to crossflow radiators. An a.I.r. Motor with a crossflow radiator (radiator nipple position) will have a "curved" water neck like found on "most" (but not all) sii and post-mid '72 pickall. Scout 810 and early sii May have come oem with the neck under discussion.

The only way to know if ya have one is to do a visual!
