Collector of "someday" cars
Yep, 18 years ago is good. Everything today is absolute junk.I paid $1,000 for my Ingersol Rand 5hp, 2 stage, 175 psi compressor new 18 years ago and that thing has thousands of hours on it and still works like new.
Well that sucks. Is your wire feed heavy enough for the draw ? Seems way premature for the motor to burn out in 3 years.Yep, 18 years ago is good. Everything today is absolute junk.
I have the "modern" version of the exact same compressor that you have.
Yep. It's special alright. Small piece of pipe with internal splines. The water pump is driven off of the cam, so the coupling passes through the timing cover. I've been told that they are an absolute PAIN to get in place, and they always seem to seep oil.Water pump COUPLING ?? What is that ? Some "special" feature of an LT1 ?
Wow, never knew Chev made such a contraption, but I've never had anything to do with an LT1 either. All I ever heard about was the problematic ignition system. Very strange engine. I can see why it wasn't around for long.Yep. It's special alright. Small piece of pipe with internal splines. The water pump is driven off of the cam, so the coupling passes through the timing cover.

I got it apart last night. It's not terrible to remove, but every time I thought I was ready to pull the pump, I found 'one more thing' that had to be removed. My attitude got much worse when I found that the power steering pump is bad. AGAIN. This replacement will make its 4th pump, counting OEM. The coupling doesn't actually pass through the cover, but the spline drive does. I'm not looking forward to trying to get that seal in place as it is very delicate. If you don't get it EXACTLY right, it will leak like a sieve. The only way to get that seal is in the timing cover gasket set. Not available by itself. At this point I'm seeing the OPTI covered in oil and road grime from the leaking seal and I'm very gun-shy about it. Everything I've seen and read tells me that the OPTI is VERY susceptible to moisture, and to be VERY protective doing anything coolant or water related under the hood. If water & moisture can get in, I'm sure the oil will, too. Since the OPTI hides behind/under the water pump and balancer, now would be the time to do something with it. Oh, and the water pump weep hole is directly over the OPTI. There was evidence of a leak there, which is why I'm doing this right now. Great job there, GM engineers. Great job. With my luck, the OPTI will last about 1 month after the water pump install... Replacement OPTI prices range from $82 (Speedmaster) - $600 (MSD) on Summit with no mention of a warranty. Local prices range from about $150-175 with a lifetime warranty. None have great reviews. This car was running fine, but I know that the OPTI was getting dripped on from the pump weep hole, plus the oil leak. I'm torn here. Any advice from LT1 pros would be greatly appreciated.Wow, never knew Chev made such a contraption, but I've never had anything to do with an LT1 either.

Yep, it's going up for sale as soon as this round of repairs is complete. I'm gonna lose my backside on this car, but nothing new there.Dang, sounds like you're falling down a black hole there. Hopefully you will come out the other side intact and maybe consider selling the vehicle ? I have never been drawn to those year cars and now will certainly avoid anything to do with an LT1 powered vehicle.
I hope you held a straight edge across the top cover. The front bolt holes look like someone really cranked them down in the past and those covers bend easily.The Quadrajet got finished this morning. I used a Cliff's performance kit and was very pleased with it. It came with a new float, complete accelerator pump, as well as the usual rebuild parts. He advertises, all parts are made in the US and ethanol safe.
