Well, here it is.
Short videos, if you care to check them out.

I need to clean out the fuel tank and put some fresh gas in it. What is in it is orange and stinks. Also has very little in it too. When switch is on, fuel gauge goes down to empty. Engine misses and sputters when applying throttle. Dies when letting off. Will crank and idle, only acts up after applying throttle. Noticed a good bit of smoke too after rev'ing it up some, but this may be due to sitting so long. I have a feeling the engine is toast, but will try some fresh gas.
This one my be the first one of mine to get a 3400.

Drivers door panel arm rest is ripping some. Hole in drivers seat. Other than that, interior is in very nice shape. Body has a few small dents and dings. Base/clear Maaco paint job. Chips in old paint were not filled before paint was applied. He said he paid $800 for the paint job.

Window tint needs replacing.

Long list of parts replaced within last few years. Cheap stereo/speakers that sounds okay. No external amplifiers.

Florida car with very little sun damage, no rust.

Looks ok, hopefully it's good in the motor also.

Is that fold down seat a Z24 only option?

The junk one over here I got the quarter window out of had one too but it was tan ( in a red car ) and the car got flooded in Maria.

Yeah, the fold down seat was an option. I don't know the RPO for it off hand. It would be in the book, but I haven't looked it up. Not sure if it was only available with the Z24 or not. It also included fully carpeted trunk area, or at least the few I've seen had full carpet with the fold down seat.

I am hoping it is just bad gas. I'm going to drop the tank, blow out the lines, replace the fuel filter and put fresh gas in it this weekend. May have a clogged injector or 6. I'll put the old gas into a white bucket and get a picture of it. What came out of the fuel pressure test gauge looked (and smelled) very bad. No idea just how long this car has set. Oil is fresh and clean though.

I have nearly everything needed for a 3400 swap. So, if the engine is bad I may go that route. I have also toyed with the idea of putting the 3.1 out of the RS in it. Certainly the easiest and cheapest. Just thoughts for now though. I'll have a better idea of what to do by Sunday, hopefully.

Beautiful Find!! You moving on up !!

Keep going and you going to catch up with me...Hahaa

Looks like I need just a couple more and I would look like another Member on here!!

Frank can have a J-Body Bash and if no one else shows up he is still good to go.....I still haven't figured out how he chooses which one to drive on any given day???

LOL, yeah, I think I have some sort of compulsion disorder.

I talked myself into simply for the fact that it is a 5spd. I figured if all else fails, I'll have everything I need to convert my 92 to 5spd properly and in a factory manner.
Sadly, I'll be losing my 94 RS. I'm stripping it for parts. Most will be stored, but wiring, dash, engine, trans, hvac, etc, etc, etc. will be going into my 88 wagon. I'll have a salvage yard come to get the hull once I've gotten everything out of it. I took it off my insurance yesterday. It is renewal time and I didn't want to pay to keep it on it for another six months knowing I would soon be taking it apart.

I was getting ready to jack the car up and saw the exhaust pipe was hitting the trailing arm. I looked upstream and saw what appeared to be black soot on the pipe. I grabbed the pipe only to find this :o

https://youtu.be/VN0FZSSA2kY

I'll take the tank out tomorrow to clean out the old gas. Get some pipe to repair the leak and hopefully find all I need is a clutch to get this car running/driving.

That's why I prefer to do my own exhaust work. It is nasty work but I know what I got when I get done with it.

My '94 came with an awful exhaust system when I got it back in 2014. I decided to get all the life I could out of it while I acquired the replacements. Eventually I did manage to get everything form the manifold to the tail pipe. That nasty system is still hanging on, but just about all my other vehicles have had theirs rot off in the meantime.....Hahaa. One advantage to using the old system up first is you are buying extra time for your new system - it isn't going to start rotting till it is hung on there. Of course the big dogs have custom stainless fitted on theirs......but obviousy I am much more of a wannabe!!





I did replace this wonderful piece of hanger at the tail pipe. I have no idea how it worked like that as long as it did.....





Love your videos!! Keep them coming :-)

Your pictures aren't showing up.

I didn't get much done yesterday. The pipe is cut and ready to put back together. But I left it loose because removing/installing the fuel tank is easier with the exhaust loose. I'm going to put a new fuel pump in it, since now will be the perfect time to put one in it.
I picked up some stuff at Ace hardware to rig up the hanger with an aftermarket insulator I got at Autozone.

If the pump is here by next weekend, I'll get it all back together and see how it runs.

Dropped the tank last night.
Found pretty old gas in it, but not much, thankfully.
Here is the gas that was in the tank.
https://youtu.be/Du0cnTnOl18

I did discover the baffling around the pump assemble is cracked. I don't know if that is something to be concerned with, of if it is mainly there to help stabilize the fuel level float?
Here is the baffle inside the tank.
https://youtu.be/Eo4FwqGJ7Uo

Hopefully the baffling is only for smoothing out the fuel level reading. Please let me know what you think.
Plan to put the new pump in it with 5 gallons of fresh gas, later today. Just hope I don't need a new tank. If it is only to keep the gauge steady, I'm not worried about that too much. But, if it has an adverse affect on fuel delivery, well that's a problem.

Gas is in the tank and the exhaust is together.

I rigged up the joint with straight/flat band clamps. Should hold it together for a little while. It needs to be welded though.

Found the cause of the knocking noise.

Got parts ordered. Will hopefully get it back together this coming weekend, if the parts arrive in time.

Pushrod is here. Lifters are out, apart and soaking in diesel fuel.

All looked good inside, but one in particular one had some thick gummy oil in it. However, this was not the one that broke the pushrod. The oil in the others was dark, but not gummy. I need to replace one. It has a worn spot on the bottom. I'll have to check the cam lobe on that one. Hopefully it isn't damaged,,,, much.

I don't really expect this engine to last very long.

That's too bad Butch, But you can always take it to "McFarland Machining " since you live close.......

LOL, I work less than 2 miles for them. Seriously.

Not quite sure yet what I'll replace it with. Plans were to use the RS as a donor for the wagon, replacing everything. Yesterday, I was thinking I could just go ahead and use the 3.1 from the RS to replace this one. Quickest, easiest, but leaves me without and engine for the wagon.
Been considering putting a 3400 in it. I need to get it moving under its own power soon though. It is in the way and holding up the wagon project. So, most likely I'll use the 3.1 to speed things along. Since that will leave me without and engine for the wagon, it will get a 3400 when its ready for for install. No real rush on it, you see. I've lots of other work to do to it before time to set an engine in it. That's probably my best option for now, I think.

I'm going to keep the original engine, just because. Store it under the shelves in the back of the garage or something. It very well may end up at McFarland one of these days.

I've had some SOHC 4cyl. engines during my years with some pretty bad cams in them due to stopped up oil passages. Many times I'd replace the cam and carrier on those and didn't have any stray metal issues upon replacing back on the road. I gotta admit I haven't see a lobe as bad as this one. You still might replace the cam and get some service out of this - and save some money in the process. For the cost of a cam and some gaskets it might be worth the chance to give it a try.

Thanks Orlen.
I'll have a closer look at everything when I get it out. Maybe just a cam kit and new oil pump, if everything else looks good. Was hoping to have it out this weekend, but don't think that will happen. Should have it out next weekend though, for sure.

More likely the cam bearings are torn up from the metal from the cam , therefore low oil pressure will be the result later on....

They are most important to maintain good oil pressure, ask Cleatus. ( He went through it twice lately with junkyard motors for Ruby the Corvette )

I ran into that problem on my Cadillac race motor before , allways check cam bearings when metal is lost and run through the motor.I overrevved and spun a bearing, changed out the crank with all new main and rod bearings , and still had low oil pressure.Changed out the cam bearings, was all good after that.

They only way to save the cam bearings is after a spun bearing or other problem is to shut down the motor and change the oil.
