LS1 dipstick hole?


Recommended Posts

My LS1 came with an oil pan not suitable for an S30 installation. The original pan contained the dipstick hole. I now have the correct pan and wish to fit the appropriate dipstick. Measurements of both dipstick outers tubes and the bore of the hole in the original oil pan are all 3/8".

 

My first concern was whether I could just drill a 3/8" hole or should I go undersize and finish with a reamer. How critical is this fit - has anyone had trouble with leakage?

 

Secondly. I took a couple of photos to illustrate this and now I'm not sure whether it is just a plug in the hole that can be punched out - any ideas?
