i got a plate from Trick that goes above the oil filter. but there are some lines above it and the plate he gave me does not have a fitting for them. so can i drill and tap that block? i will look more in to it tomm. but i did not know if this has come up in the past.

 

Does your truck have an Aux. oil cooler on it already???

 

sounds like it. Do a search. you've had ten threads in three days...

 

yes i have a oil cooler. and yes i have looked on the past post and everything i have found they dont have a oil cooler or they are putting on a oil cooler. i have one from the fact. and guess i need to tap the block below the oil cooler lines on a flat spot. i dont think it will hurt anything.

 

that is where my oil feed is set up. and i have the return on the passengers side of the pan near the front.

 

i ordered a plate from sts there's gos between the oil cooler lines

 

murdered_outgmc so did you just drill and tap the plate in the middle? love the all black truck. some times i wish my truck was all black!!

 

Here is what the STS comes with.

 

Thanks man, yeah the plate is just drilled and taped, let me know it you want some pics.

 

The older STS instructions had you drill and tap the OEM block in the bottom, 15/16" from the rear of the block, near the plug in the one in the picture above. Drill a 21/64" hole and tap to 1/8" NPT. Coat the bit in grease to hold the shavings. Start the engine for a couple of seconds to flush out any shavings. You can do it without the STS adapter but it is a hard place to work in if you are 4X4 like the one in the picture. I unbolted mine enough to flush it out with paint thinner (or varsol). The job gave me fits but I got it done and it has been fine for almost 4 years.
