<VV> [fastvair] Repair to engine oil pan bolt holes

[Jim Becker]

I subscribe to the same philosophy, use the method that leaves the most 
original material on place.  Go to the next method if necessary.  I believe 
a Helicoil leaves more of the original.  (Think about it, a coil of threads 
vs. solid insert.)  I have yet to need a Timesert.  For the next step back 
on keeping the hole small, you might also consider "Loctite Form-A-Thread" 
as an alternative.  It obviously isn't an option in a high stress 
application but might be OK here.  I've never used it for a pan bolt but I 
have for rocker covers.  It held up at least as long as I owned the car.  I 
suspect it may fail after a relatively small number of remove/install 
cycles.  When/if it fails, you can still go to Helicoils the Timeserts.

I have used many types of inserts and prefer the Heliecoil for two reasons. 
One they go in flush with the surface and two they are Stainless Steel. 
Another aspect is that different inserts ( Same Thread Size ) require 
different hole size. Why this is important is that if you use the smaller 
size first and it would get damaged , it can be replaced with a larger 
Diameter insert. ( I believe the Timesert and the Helicoil are about the 
same OD ) Jack Frostvair Garage
