Good day, I have been a W body enthusiast since high school 04. In my student parking lot, we had a 93 Gran prix, 94 olds cutlass supreme, 94 cavalier z24, 95 monte, and my lumina z34. These cars were everywhere! My first car was a 94 lumina z34 (still have it). In 2012 I put a 4.9 PFI in it and it is almost complete. I just need to replace the rear suspension and odds and ends. I have a 99 Monte (needs some work), and I just picked up a decent (needs some work) Cutlass supreme. I am buying a new top for the cutlass on Friday. I want to get black canvass instead of the white (the car has black leather interior). They come in black, grey, white, red. What do you all think would be the best color? Just curious. Very few of these ole buggies still around (at least in my area).  I thought I would join the forum to see what you all are up to (I feel very late to the party). I already have seen some super nice examples of these cars (nice job everyone!). Ill post more as spring hits and I can get them out, and work on them more. Also, not adverse to loading them up on the trailer for any meets that might happen. Thank you! Hope you all have a wonderful day!

If you need to pull the engine, I may consider the following:     - the block mounted crank position sensor.  They often get stuck in the block and break.  You either need to drill and put a screw in them to pull it out or they break too bad and you need to push it into the oil pan and hope it doesn't cause issues or pull the pan.   - Steering Rack ensure there are no leaks.  Much easier to do without the engine in the car.   - Engine and Trans mounts 

I've ground the top ridge of the pump drive down slightly to allow for more room to work, then use a distributer gasket for a Lumina van with a 3.1, just give it a cut and slather it in RTV, seems to work well. and I'll be damned if I'm pulling a head just for that.

It's in the valley right by where the transmission and engine block are joined together.  Oil will pool around the distributor plug (also called "oil pump drive") and run down the side right where the transmission mates to the block so where it drips on the ground looks very much like a rear main seal.  An O-ring goes bad on it allowing it to leak.  Shine a flashlight down there, and if there's oil pooled in that area, that's your culprit.  Unfortunately, yes, it's blocked by the rear head.  What most people do is lift it up as high as possible and clean it and the block as well as possible.  Some sandwich a thin O-ring under it, others RTV it.  My memory is hazy, but I think I may have done both.  On my pic, high pressure oil-resistant RTV is the stuff kind of squishing out from under it.  It's dirty because this was many years later, but it worked great.  Official GM procedure is to pull the rear head, but that's way, way too much trouble.

This is an excellent point, can you pinpoint and/or provide a photo as to where this is? For the life of me I can't find it and/or provide the page on the 1994 W Book that may provide a diagram where it is located? I would really prefer not to pull the motor if that can be avoided. Thanks for this memo, much appreciated
