Never use that stop leak @!*%. It will gunk up your lifters and your truck will be junkyard bound. Fix the seal, take a small hit, drive for 100k more miles happily. Also, good thing you use synthetic oil, especially on a VQ. Forget the BS about synthetic oil making seals leak. Dust should not be holding seals in place anyway.

The gasses are compatible but the oils may not be. You can also use either an R12 or an R134 compressor and it would not make a difference. I currently have an R134 system with an R134 drier and the R12 compressor.

anything is possible

That is the modified cross-over pipe done for her. I have the original and here is how it looks like:

To get anywhere near 30 MPG, you have to increase the power by about 100 hp. A VG33E+T may be able to do just that.

These are her pics: I'm building a similar setup. When I finish, I will be posting a write-up.

A gasket alone will seal that @!*% right up.

Here is the finished first section: With a little bit of overlap (~>1mm) for longer gasket life.

yep, that's the idler pulley

nunya should be here shortly to help you out

his is an 01 so yeah chances are it will fit an 03
