For those of you who have tapped your oil pan, did you have to use a right angle drill? It doesnt seem like there is enough space in there to get a normal drill in there.

I don't think you can drill unless you are taking the pan off.

 

do not drill it unless you are plaining on taking the oil pan off. you are have to use a punch then tap the pan to get the threads for the fitting.

 

the vortech install guide has you doin it with it still on the car. I guess i could just take the pan off. how hard is it to get the pan on and off

 

i meant use the drill and tap. Not an actual drill bit

edit: nevermind i misunderstood what i was doing lol. no drill needed. i thought you were supposed to use a drill to thread the tap in. im a retard

 

I'd remove the pan just so you can clean up the inside of your tap, any time I've ever drilled and tapped I've had metal chips on the other side.

 

Do you have to drop the k member to take the oil pan off a 99-04? I hear it is much better to take the pan off and either weld the fitting on or at least hold it on with a nut on the inside of the oil pan.

 

well, vortech manuals instruct you to do it it with the pan on so im sure its safe to do...i just need to see if my friend has punches.

 

leave the oil pan where it's at, tap it, tread it and be done with it.

 

If you are punching/tapping, as soon as you're finished tapping they tell you to drain the oil. I would put your drain plug back in and fill up with fresh oil (not synthetic or anything expensive). Drain the fresh oil and go over it with a magnet. Keep doing this until no metal traces are in the oil. This way you know all the metal gets flushed out. Might be a PITA but I think it is better than having shards of metal going through your motor.
