Do you see all the funk in the grooves of that tap?

 

I couldn't get the tap to bottom out of the cylinder head bolt holes due to them being packed with 45 years of ooey-gooey.

Flat cat was that a thread chaser or an actual tap.... you need to be careful using a tap, sometimes they will cut instead of clean the threads....

 

 

It was an actual tap. And I'm not new to this.

 

Interesting to see if it leaks when its back in the truck? You do the head gasket as well? Or just clean/paint/chase?

 

The reason for leaks was the lack of cleaning/surface prep from when the previous owner had this torn apart.

 

I am not doing anything to this motor other than clean, paint, reseal, install.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Unless....

Obviously your not new to this, but others who read this are..

I Wasn't trying to insult you or anything... but others might not be smart enough to stop before they do more harm than good....

Chasing the threads is definitely a good idea... but using a tap to do it, may not be the best idea... using a thread chasers is just a better recommendation...

That it is. I was unclear of your intentions. We're good.

 

 

I actually ran a rethread through it first then used the tap covered in grease. I think they do a better job pulling the debris out.

 

 

 

 

So, now I'm arguing with myself about keeping stock 210 cam or installing the U20 camshaft from my W53.

 

Decisions.

I won't be using the W53-just the camshaft, rockers, and pads.

 

Everything else will be original 210.

 

 

 

 

And still...this is all just temporary. I've got nothing to lose by doing so...and I'll gain a little mid-range power. Win.
