Hey guys where is the best place to put my oil return line on my 2002 Z24 Cavalier? It has the 2.4 dohc and a manual transmission. I am installing a turbo on it during next week while im on vacation. Please describe and post pics if you have them.

The back of the block.

as high up in the oil pan as you can get , or the block like his ^^^ is if you have the motor out of the car

^ Nice piece of work Skilz!

DCStang - if you're not intending to pull the engine - here's another option for you. The pan can be pulled fairly easily with the engine in the car. The pan can be tapped high (toward upper flange rail) in the first flat section (between casting ribs) right after the pan goes from shallow to deep, on the back (firewall) side of the pan. This location stays clear of the hard water tube that runs under and up the backside of the oil pan (it would be just to the right of that pipe toward the front of the engine) and places the drain fitting as high in the pan as possible while also keeping it clear of the balance shaft/oil pump assembly in the center part of the pan. I tried to post a picture of our no-weld oil pan tap location from the instructions for our 2.4L turbo kit, but obviously I am "technically challenged" and couldn't get it posted here! Hope this helps anyway.

any other suggestions? or dissagreements with the three listed above?

I like Shilz. his is the first I have seen on the block nice job!!!! Tmine is in the oil pan, but might switch it when motor is out.

could the plug in the block next to shiltz return be used as a return? I know the coolant tube is blocking it but would it be possibla to use a 45 degree elbow to get by it?

that is main oil pressure where that plug is


mine is the same place as in the pic leo posted , but mine is up higher , i had to notch the pan rail , but i wanted mine up as high as possible

How did you guys tap the hole you drilled? I am having no luck finding a tap big enough

i got mine at home depot

I went to home depot and looked for a half hour in the plumbing dept and the tool dept. then i asked a moron that works there and got "what is that?"
