Hi folks! Sorry I've been offline for quite some time. Been working overseas and it's been crazy! Anyway I finally got around to fixing the leaking steering pump on my 84 Century. As far as I know the PUMP is original to the 1987 year engine (which i bought as a core engine). For quite some time, it has leaked oil slowly, so that if the car sits for a month or so, all the oil is gone out of the steering pump. So, today I fixed it. I was quoted a high sum of money for a "rebuilt" pump of dubious quality. Forget the chinese knock-off ones. The seal kit was about $15. This is a picture-intense thread, because that's the best way to explain the steps. There is nothing hard about this, but you do need a couple special tools (pulley remove / install tool, and drill press). The puller is available for rental from Advance Autp Parts. There are several variants of this pump. The main difference is the shape of the reservoir. The repair procedure is the same for them all, aside from the reservoir removal could vary a little. The pump...

Dug up the GM Service Bulletin for "Lifter tick when cold", 57-61-09. '91 to '95 LQ1 (VIN X)

http://mymonte.com/discussion/topic/...e-%2357-61-09/ The parts kit has been discontinued by GM long ago. My quest was to find sources for those parts; and complete the procedure on my '93 Lumina Euro 3.4 which was torn apart to replace the rear head gasket. There are three critical part numbers in the GM service kit (aside from gaskets and O-rings) required to perform this operation. Two of the three are readily available in the aftermarket--the 10-32 set screws, and the cup plugs. I hadda buy a box of cup plugs and a batch of set screws; if you can't find 'em locally, send me a PM. All gaskets 'n' seals are readily available, and are included in the gasket set I needed to replace the head gaskets (Fel-Pro HS9113PT1 Head Set.) This leaves one item that is expensive to source--the replacement thrust plates. Reading the bulletin, and...

There have been a couple of guys who wanted to know how to read a compressor map. Hopefully, I haven't made any mistakes this time (unlike the last) and this will prove to be useful to you in your understanding of a compressor map. Reading a turbo map isn't as difficult as it looks. The map displays 4 key pieces of information. A. It displays the pumping efficiency of the compressor (meaning the amount of actual air that it pumps in contrast to the amount of heat that's created while wasting energy) B. The physical amount of air that it can move in pounds per min (just like it says, how much air per/ min) C. The pressure ratio of the air being pumped (that is, the ratio of pressure that it is capable of that pumping in contrast to the ...

GM has recently released their 2012 Product Guide, which details all of the engines and transmissions used in production vehicles, as well as the specs of the engines. Several years ago, we used to outline these updates, but have been lacking in getting the information out for the past few years. In an effort to try to keep the site up on the most recent releases from GM, I am trying to get this information back into articles again. With that said, on to the information.
