whats the correct location for drilling the pyro sensor in the manifold? and whats the best way about drilling it to reduce the risk of shavings getting into the manifold.

good info right there

 

drill it with the truck ideling.............done quite a few that way never a problem .......same thing withthe tap.......shavings out the tailpipe

 

thanks for the link and the tip on leaving the truck run.

 

Pyro should be installed right here...

 

or u can use lithium grease and it works as well if not better than as its runing. no metal in turbo at all and all u have to do si dip the tip of the bit in the grease every so often and do the same with the tap. Have done many and there is a fleet of trucks that have been this way.

 

 

i drilled it till just the end of the bit barely pocked through. to gather the filings.
finished drilling and put grease on the tap. then cleaned up with a pencil magnet.

 

It takes all of 30 minutes to R&R the turbo, at any rate.

 

The idle technique works well, unless you break the bit or the tap. Then bye bye turbo.
