Cool pic, inside of the 4.2L oil pan.

You can see how that axle receiver tube is cast into the pan: http://cgi.ebay.com/ebaymotors/02-Trailblazer-4-2L-Oil-Pan-HCAN_W0QQcmdZViewItemQQcategoryZ38657QQitemZ200094 117859QQrdZ1QQsspagenameZWD1V

thats just for the gasket huh ,, that IS an awsome price no doubt , cool pic too.
:offtopic: :hijacked IF i cut that tube out of the oil pan and boxed in the spot that the shaft went through the pan i wonder how much capacity that would remove, im going to "GUESS" and say 1.5 quarts. that would that let us lift the trailvoy higher? roadie?:hijacked :offtopic:

that little add on to the pan is what makes the 4.2 require 7 quarts of oil... AND this allows the engine to sit lower, and lower the center of gravity for TB.... have you guys seen how much higher an explorer hood is next to a TB?

ah i agree with you.

im hoping roadie chimes in on this one. im thinking hes already thought of this for the Rubicon idea.

He ain't the only one....

Very cool pic indeed. Snagged it. Thx.

The fortunate thing is they did the passthrough with a tube, but we already knew that because you can see it on 2WD vehicles. It means removing the differential doesn't affect the engine.

But a big (>4") lift doesn't require you to remove the tube or close it up or machine anything on the oil pan. You just unbolt the differential and a couple of other important parts :D and bracketize them underneath the engine on a new front crossmember. So the minimum lift amount becomes 4-5".

For further reading, see the installation instructions for a Procomp Tahoe 6" lift.

Relocating the front differential is one of the easier parts of designing a big lift. What CANNOT be done by the typical small fabricator is to do the longer steering knuckles required, in forged ductile iron. I've read a LOT on lift design in the last year.

And at the end of this project, you would still be left with a weak aluminum housing AAM differential. I'm not salivating anymore over the possibility of this sort of lift.

well there it is great info thanks roadie

What looks interesting to me is what appears to be oil scorched on the housing around the tube ends. Looks like it got pretty hot in those spots...

No wonder the 4.2 takes so much oil!:duh:

[tireguy200]

I'm not sure what the correct word is but, did anyone notice there are no baffels or blocks to keep the oil form moving front to back or side to side under cornering. I'm new to looking inside truck parts but in a performance car this is important for when you are cornering or launching. Any thoughts?:confused:

This is true...although I suppose it is a rather narrow oil pan itself (I6), which I would imagine would help with the side to side...and I would think that big ol' hole through the center would serve as front to rear baffle.

As far as lifting goes...while a small time fabricator couldn't make all of the necessary parts, and certainly not of sound structure...perhaps could a true industrial heavy hitter, like sky jacker, or fabtech, or whoever? I'm just really hypothysing about it now, as I've sort of given up on someone coming out with a lift like that for it...but it is still fun to dream.
