I picked up 2 engines today from the yard.

 

95, Non - EGR Long block only as the manifold did not have the EGR Port.  I have a 95 manifold with EGR

 

97 Non -EGR complete engine, the manifold has the EGR port blanked.  

 

I'm looking to drill and tap the heads,  I remember someone posting they drilled into the water jacket, so I just wanted to double check if both engines can be drilled.

 

Thanks, Larry

They can be. GD posted some tips in a thread about drilling the EGR ports a while back.

Basically you measure the depth of the threaded section on an engine that has it already drilled. Stick a drill bit in (the size you need to make the hole) and mark it with tape. Then only drill that deep into the head you need to tap.

If you have a drill bit stop that's the best way because then its not possible to drill any deeper, and the base will be cut smooth so the flare on the line will seal properly.

Thanks, now I hope Napa has the tap.

there is a work around if you don';t want to do the drill and tap.

Thanks, that's the way I'll go on the 95 dual port exhaust engine.  Going in Sat1
