i got my 4x4 oil pan and pick for my 03 vortec motor i'm dropping in my ty. where do i need to drill the hole for my turbo oil return line and what fitting should i use.

also i've seen mention of a slight modification to our stock valve covers to fit vortec heads and was wondering if anyone had a picture or description of what i need to do.

i'm tryin to get this motor ready to drop in as soon as i can get the old motor out but since i just had hand surgery again i can't do that right now so any help with this would be appriciated.

take the corner of the valve covers and try to set them on the vortecs, you wil see the radius on the corners will not fit, just either bend out the valve covers to fit or grind off the corner a little, the thick gaskets still seal them well. you can put the drain anywhere between the mains usually between the 1st and second main has the most room when installed

I have #10 weld on bung. Don't put the fitting in the stock location unless yours going to out a 90 degree fitting on it, otherwise it will hit the frame. E-Rue warned me of this, so I looked at my stock oil pan just before I pulled the motor out. I would put it 4-6" back of the stock location.

so one suggetion for between the first and second main and one 4- 6 inches behind the stock location. so i'm guessing the stock location is close to the front? i hate to keep asking acout this but it's near impossible for me to crawl under my truck right now.

We basically talking about the same area. I ran out to the garage and the stock location is about 1/4 way down the oil pan in the front.

Re: vortec motor swap question

awesome now i'm confident enough to make the hole. so a -10 will fit th stock line? i'll probably use a pass through fitting or drill and tap, since i don't have acces to aluminum welding equiptment and would probably catch my bandages on my hand on fire if i did
