If the nipple on the thermostat housing is bad, there are replacements.

i just installed BEST intake gaskets and all is well. part number 14043!!!! they did fit 272 y block

Im having an small issue getting a miniscule annoying coolant seep from coming out of the bottom of my Radiator hose at the thermostat housing connection above the bypass hose there which I am actually unsure if that bypass hose is also holding tight and not also seeping...I reused the 3 month old  silicone hose connectors that attach to the bent pipe connected to the thermostat housing. All of that was doing this same annoying seepage on the very last attempt last Thursday with the incorrect intake gasket so it was not a surprise here that it continues...I replaced the bypass hose last night because I actually damaged the other 3 month old one digging the clamp into it on the last go around... all of this is why I havent put the oil bath and the hose and the special cover air intake fixture back on the teapot to dial everything in yet...all of that gets in the way to fix coolant leaks etc...

Like Charlie mentioned, if there is any doubt as to the integrity of the thermostat housing, replace it.

MUMMERT has nice repros. Make sure where the housing goes to the intake that the intake mounting is not eroded also. Same where the WP fitting goes to the WP (by-pass hose) and the WP mounting boss also.

Do not use worm clamps as they will damage the coolant hoses. Shown below are two styles to use with silicone hose -

GATES Hose Clamp - Green Stripe® Silicone



GATES Hose Clamp - Green Stripe® Constant Tension Clamps






Put a pressure tester on it and make aure it holds pressure.

What Intake Set did you find to fit (Vendor and PN)?

The bypass tube or nipple within the thermostat housing and on the water pump tends to rust out.  If the leak continues, take a close look at those.

All it looks like I have had success after receiving all the help you all have provided. My intake manifold is back in place on my engine. I started the engine late last night and it ran well enough without the air intake and the left valve cover on it for a brief see what was what....Im having an small issue getting a miniscule annoying coolant seep from coming out of the bottom of my Radiator hose at the thermostat housing connection above the bypass hose there which I am actually unsure if that bypass hose is also holding tight and not also seeping...I reused the 3 month old  silicone hose connectors that attach to the bent pipe connected to the thermostat housing.

I have edited my very first post of this Help finding the correct Intake manifold gasket Post at the end of it with a basic SUMMARY of that fix to make it easy for the next reader to get information if they should somehow run into a similar thing...or for any of you to see what info you provided that bore fruit for me...Once again thank you to all of you.

Love your truck, perfect for your business.

Hey Gary,   Hows that thing coming?  Did you figure out why it's running hotter than before?

Thank you for the compliment on the design of the box....Kultulz...That was a colaberation between myself and the graphic artist whose company has the contract with GEARWRENCH. After my Matco Truck was stolen in 2015 Gearwrench came to me on a fishing expedition asking what my intentions were in coming back...they made it known they wanted me to be a part of their "Street Team" I had to play it cool at that period because I was still a franchisee for Matco...I told them if I ever were to consider what they wanted I would not do so with the two wraps they offer their people...I had something else in mind....they told me they would pay to have what I wanted produced as a custom for me thing..."we are thinking of allowing custom wraps for our folks anyway" It took about 3 months to work with their guy and it ended up costing Gearwrench about twice what they thought it would..Even though they were thrilled with my result....I will be the only custom wrap you see with the Gearwrench logo...
60 percent of what you see in my showroom/mobile tool store is Gearwrench the other 40 percent is whatever you would see in a Snap on or Matco or Mac Truck without those names lazer etched into the tool...Snap on  still produces about 5% of what you see in one of their trucks that means that 95% is a private label type of thing...I have gone to those brands and asked them not to change out the handle, to keep their name on the tool and sell it with he who built the tool's name on it...same warranty, same tool, maybe a different color or shape of handle...save 40% due to cutting another distribution system out....I go where I want, sell what I want, drive what I want....my customer tells me what is what...not some franchise flag....Now I just need to get this truck back to the street to actually do that....
I want to do one more piece of art work on ETTT....In that large white box area behind the cab, I want to put the Preamble to the Constitution....as soon as I get back to seeing my clients and get into a routine...I am going to find someone to help me do that.....

Tedster9 I really need Ethyl up and Running NOW....actually by Tuesday Night...I might need to find another Engine to put in Ethyl and then go through the one in her right now....That way can run her with the least amount of down time...I like being on top of things and right now I am not. That is most of my problem right now...not being on top. Thanks for suggesting this forum too....lots of knowledge here also...Between the two I should be ok and maybe stop making critical errors...I have an interesting engine....Really a 256 cid Y Block...Except maybe the block....eventually I will see marks on the front of the engine to see what will tell more of the story with that block...The truck WAS produced late in the year for 1955 so maybe Ford had to do some shifting of gears to make things happen...either way...that block number showing 272 and the rest being 256....I wonder if things like the front timing chain cover and the special high mount water pump can transfer between the 256 and the 272...I hope so...I have a NOS water pump for what I think will replace the one on ETTT right now on the shelf waiting for that day when it shows it doesnt want to play any longer with the bearings it has in it now....That is a hard item to find...once the one in her fails Ill send it out for rebuild.
