Lining Ducks Up: Tapping Brazilian Block for Thermostat

Feb 20, 2004 12 Replies

As part of my engine-out got-less-than-a-week-to-complete-it project, I need to tap the bottom of the block (Type 1, Brazilian) to install the thermostat mounting stud.



I was looking at my tapset and it seems that the T-handle is gonna be bumping up against the underside of the head/pushrod covers area. Am I mistaken? This looks messy -- I don't want to pull the head. I'm not real familiar with tools available for doing this kind of work. What might be the tool/technique for doing this?


good luck

Don't use a T handle. I have tapped, laboriously, with an adjustable wrench and the patience of Job. Colin

Yup! There should be enough room for just the tap. And if you drill a nice clean hole, you can carefully get the tap threaded into it straight and nice, little by little, using either an adjustable wrench or some other similar type tool. Maybe a small Vise-Grips (tm), something like that. Even a needle nose pliers, which might actually be better for getting the tap started, while you apply downward pressure on the tap with a finger.

PS: how ya gonna drill the hole? ;-)

John Kuthe...

That's encouraging.

Gulp. That's not encouraging.

Don't use a T handle use a ratchet with a socket to fit your tap....I did and worked great. The force is minimal that you have to use..Eric ...... been there done that

Cool idea.

Been there, done that... :)

Jesus,it ain't that hard.Ya ain't buildin' a watch! There's a reason why the tap handle slides back and forth.

Okay, okay! My tap handle is about 6'' long and the tap goes right into the center. The only sliding I get is when I don't tighten the handle onto the tap very well, and the handle slides off the tap. Hilarity ensues while I mutter and ask myself how I got into this mess in the first place.

I love it when hilarity ensues.

To someone else.
