    The pcv valve could also be clogged. When this happens the car sprouts oil leaks. Which will probably decrease but not stop once the filter/screen is replaced.

    After washing the engine compartment, Change the PCV, filter/screen and grommet. It is a small PITA but is not expensive and is always a good "new car" step along with making sure the kickdown bushing is brass not plastic. (can't remember if you mentioned that as being done already.)

    In general these are the two things to start with on unknown boxes with these components in addition to common things like fluid and filter changes.

    It certainly would not hurt to follow NICK's advice either as there is a good chance all his recommendations will need to be done at some point.

      I'm suspecting valve cover or intake. I might have a perma-dry gasket set laying around that I was intending to use on the Mustang. I'll check.

      Here's what's left of the spare. It's been replaced for the time being with an extra turbine from the junkyard.

        A few things. Had a honey-do to take care of, so I didn't get as much time as I would have liked after work today. I decided to tackle the front driver's window motor since the below package arrived today.

        Yes! $18 got me a box of 100; these are the same ones they sell in the HELP! section at the parts stores at $8 for a card of three. You can even get the same box of 100 for $8.00 on Rock Auto, but the shipping was kind of expensive for some reason, negating the savings.

        Once I got the panel and everything else removed, I realized what my problem was. The window regulator arm pivot stud somehow came loose from the plastic bushing that runs in the track. The previous owner's fix was to secure the window up with wire and disconnect the window motor. Then I made an idiot blunder when I removed the motor and attempted to replace the gear bushings. I brain farted and forgot that the metal gear is held in by a clip. I pried on it and ended up damaging it beyond repair. Gonna order a new gear off Rock Auto. Not sure what I'm going to do about the regulator. I can't fathom how the plastic piece came off in the first place. The hole is too small to simply snap the pivot stud back in. Pics.

        It was at this time that I ran out of daylight. On another note, something I ordered came in today.

        I supposedly found a NOS battery hold-down bracket on eBay, but it's too tall to be bolted down at the factory location and is too narrow to fit around my Motocraft battery. I don't see a part number anywhere on it and it did not come in original packaging. Were the original batteries that much shorter/narrower? I also found a NOS front license plate bracket on eBay. My car was originally an Oklahoma car and did not have the front bracket installed. This one is brand new in the orignal package; only problem is that it's a bit out of shape. It looks like it's been underneath a pile of parts for a while. It comes with two mounting screws and plastic rivets. I was rummaging around for my horror fright rivet gun, but I can't find it. Looks like I'll have to spend another $0.99.

        In another bit of happy news, I do indeed have an extra set of Fel-Pro PermaDry valve cover gaskets laying around. I also have an extra set for the oil pan and a PTFE rear main seal that will probably go on at a later date.

        So as of right now, both driver's side panels are off. One is waiting for a new window motor gear and for me to figure out this regulator situation. The other one just needs some more time.

          8 bucks for 100 of those? I was thinking of measuring them and buying some rod stock to cut my own, but at that price it would not be worth my time by any stretch. Hell, I doubt I could buy the material to make 100 of them for 8 bucks.

          I do not recall any retaining clips in the window motors. Maybe its a later model thing. Mine all had one screw holding a cover plate on, removing the cover let you just pull the gear right off the axle in the center of the whole mess. Mine is an 86, the gear head on the window motors has a 1960's part number on it, the motor itself has a 1970s part number. Only thing that changed in the 70s was they went from a round plug to a rectangle.


          I wouldn't worry so much about the pan or rear main. They rarely go bad. Most of the oil pukage is the valve covers and the lower intake. My Mark VII has 250k on it, and after changing those it doesn't leak oil. Oil pan has never been off, and I would lay money on the rear main not having been done when the trans was out of it.

            hmm... looking at scott's video that must be an older model thing where only the cover holds the gear in... http://www.grandmarq.net/vb/showthre...l=1#post615971

            The newer ones are also held in by the cover, but there is also a c clip on the top end of that axle that holds the gear in. So you can't just pop it out like scott did in the video in that other thread. I never realized that was an older model thing, unless you guys are all missing your c clips.

              I ended up breaking the plastic piece that goes on the regulator while trying to reinstall it. Looks like I'll be needing a new regulator. I couldn't find any place online that had the piece. Anyone have an extra regulator lying around?

                What piece are you talking about? I don't know of any plastic parts on the box regulators.

                  The rectangular piece in the fourth picture on post #33. It goes into the window track. I think the regulators are specific to '90-'91. That piece somehow came off the pivot stud on the end of the lift arm. Tried to get it back on and just ended up shattering it. Very sad.

                    Its not specific to the 90s models. The older ones had that same plastic slider in the track under the window glass.

                    Thats the later style motor. I see the C clip groove on it. Mine doesn't have that, and the motor itself is a fair bit larger. Annoyingly, its not actually as powerful so my windows run a little slower, and being a Lincoln its got a more complicated window regulator mechanism too.

                      I'm going to call junkyard in Dallas that had that 1990 GM from which I picked parts last Friday. Hopefully it hasn't yet been crushed and they can pull the regulator and motor and ship it up here.

                        ah... that plastic bit. I wouldn't know how to remove that without damaging it or put one on if you managed to get one without damaging it. I would say heat at 150F in a oven (toaster oven) for a couple of hours (inside foil to keep it from out-gassing and contaminating your oven) and then install while hot (gloves might be a good thing), but getting one off a regulator would be the trick.

                          I've put them back on by using a pair of vise grips. Put it in the track under the glass, put the ball end of the regulator into it, then squeeze it together. Its a pain in the ass, but it can be done. Unfortunately if its out, it might mean the plastic got damaged somehow and it needs replacing. I believe the same parts are used on Mustangs, so there is a fair bet you can get one from LMR.

                            I can't figure out in my head how it came out in the first place. I couldn't get it back on the arm because the hole was tapered and just would not fit over the stud. The good news is, I called the junkyard in Dallas and they haven't yet crushed the '90 GM. They're going to look into getting me that regulator and shipping it up here.

                            On a happier note, I spent the past week piecing together the parts to do the later model intake tube/air box swap. It's not an exact fit, but boy is there much more room on that side of the engine now. I also did a little bit of a spray down of the engine bay with the garden hose. I still plan to power wash it, but I'm waiting on new PCV parts and the intake manifold gasket I ordered to do that. Pictures.

                            Clean(er) engine bay.

                            Found this written on the passenger side of the header panel support written in pencil. I think this car has a lot more miles on it than I thought. Haha. No matter. Everything that needs to be fixed will be fixed. No matter how long it takes.

                            I think the radiator was replaced at some point. The fan shroud was fastened to the radiator with 7/16" bolts and nuts rather than the u-nuts and standard bolts. I grabbed some new bolts and u-nuts online and used several during the install. Looks just like the factory intended.

                            All done. The air box didn't fit the available bolt locations. I'll probably look into fabbing some adapter brackets later on. Found a bunch of dead ants under the intake plaque. I really need a shop light.

                                I grabbed the insulated mounting studs from the donor car, but they don't line up exactly. I'll have to fabricate some brackets if I want it to be installed somewhat correctly. I had to force the air tube onto the box and would like to see about getting an improved mounting position which allows me to reduce the stress on the air tube.

                                Only thing I have left to do is install the newer washer fluid reservoir. The one I have is out of the same '07 CVPI from which I pulled the air box (same junk yard that has the '90 GM). I grabbed the connector from the car since it's different than my original. I was going to solder it in but ran out of daylight. I'm just going to hold off on that and see if I can find an earlier reservoir that has a motor similar to mine.

                                I have so many parts I want to buy, but money is a little tight right now. I now have three cars (and my wife) vying for a slice of the pie!
