Where the Hell do you get all this popcorn? Haha. It's a method Phonedawgz mentioned a few pages back in this thread to get the timing close without having the vehicle running.

Matt, I have a lower intake complete with thermostat/filler neck attached. If you decide you need to replace it, let me know. Maybe we could meet up around Eatonton or Dublin.

I still have a middle and upper intake I took off and a complete motor in the 87. I am just trying not to convert back because I don't understand how it could have gotten messed up. I will compression test it this week.

So i compression tested the motor, and all yeilded around 45 psi. I'm gonna try some oil in the cylinders and do it again.
Edit: after adding oil to cylinder 1 we got about 150, but after that, the valve core one the tester was allowing air through so we will have to get another core before we can do another test.

I need some advice. Lol. I cycled some oil on the cylinder walls with plugs out and imjectors unplugged, I will do it again tomorrow, oil smells of gas again so maybe change that and put some compression restore in it. Since the car hasn't been starting every time I try and start it all the fuel from the objectors was washing the cylinder walls. We will see what happens. Wish me luck. I would love to get it running, and move onto getting the 87 running.
I'm tellin' ya'; I would pull the fuel pump fuse until I got it to run on starting fluid consistently. I wish you were closer so I could come down & help. I sent you a PM at the Ga. club forum. ~ Paul aka "Tha Driver"
+1 on that. Pull the fuse and get it to run on starting fluid. Make sure you have a fire extinguisher handy anytime you are trying to start it with the snorkel off. A single backfire can start the car on fire.

Changed the oil, and attempted starter fluid. Still won't start, but it sounds better when starter fluid is sprayed. Also I'm not sure if its normal, but there is smoke coming out the valve cover to intake tube. It's done that everytime I've added oil to the cylinders, and also smoke inside the rear valve cover with the oil cap. Just wondering if that is normal.

Well I know it smokes real bad as you have seen, when oil is added directly to the cylinders, and yes once I put some oil in the cylinders, I got 150 psi in all 6. So I thought maybe that was just the burning oil venting through the tube.

Idk, just a thought. Everytime I put some oil in the cylinders or ever sense I started that I have noticed the smoke coming out the tube. Idk, just thinking of different things.
I added oil to all cylinders, and compression tested it again and all are around 150
Correct me here if I'm wrong but doesn't a higher compression reading with oil in the cylinders indicate a ring/cylinder wall issue?
Also the smoking, is that related to oil splashing up the EGR tube? I've heard thats a common issue. Long shots both but shots anyway. Love to see you get this baby running.
Update your mall add with the 87 parts your selling? We are always looking for the right parts at the right costs!

I'm selling the complete 87 car. And I have no egr, and also I have a remanufactured motor in FIFI, so pistons and rings should be new. Could be wrong. I expected low compression at first since all the fuel probably washed all oil off the cylinder walls, and after cycling some oil through, I may have temporarily improved the compression. Idk. Just a shot.

Here is what I think: your ignition timing is totally messed up, way advanced, or wires to the wrong plugs, or 180 degrees off or some other BIG problem. Here is why I think so......
1. you broke your starter.....why? because the engine suddenly went backwards when the starter was pushing it forwards....firing at the wrong time. 2. It won't run on starting fluid. If there was a problem with the fuel system, it should run on starting fluid. IF the car does not run on starting fluid, there is something wrong with the ignition somewhere.
I know that you checked all this stuff....probably a dozen times....but what you need to do is start over with a clean slate and look at it with fresh eyes, assuming that something is wrong....and not quickly decide that it's OK.
Why does this look wrong? Looks like theres WAYYY too much oil in that valve cover. I dont think I've ever seen a valve cover with that much oil in it. Is that oil thats visible?

I would, as others have suggested, check your timing, sounds like your timing is way off, how old is the distributor? bad module maybe? or a pickup coil? I've got a brand new dizzy and 2 sets of injectors(one stock, one from a 3.1 firebird) I'll give you if you pay shipping.
I though I remember you saying somewhere the car was converted to DIS and then back to a reg Dizt setup, if that is the case, I would re-check the ECM connectors fpr the correct pinouts.

Ericjon I may take you up on at least the dizzy, everything else spark related is new. Injectors seem good and hold pressure. And when I had the rail out, they all pulsed when the car was trying to start.

just let me know, I don't need it, I'm doing s 3500 swap.
as far as the smoke goes, the smoke leads me to believe you are losing pressure past the rings, I would do a leakdown test and make sure you're getting a halfway decent ring seal.

Does anyone else see a problem here?
If the cylinder walls were gas-washed, should the compression be that low? Is that low enough to stop it from running?
This is not an attempt to add to the confusion or muddy the waters. I really don't know. That's why I'm asking.

I will try a leak down test, I really don't think my timing is off by much, car turns over fine and there isn't back fire through intake or exhaust. Would it seem right at 180* off?

Why dont you take your valve covers off and your distributor cap and watch the valves and distributor at the same time as you rotate the engine. This is the best way I would think to cross incorrect timing off the list and narrow down your problem. I think the spark plug points to the intake valve? There is no reason why an engine should be this hard to figure out and if your timing is correct and your leak down test checks out and you have fresh oil and you unplug the fuel pump fuse and you still cannot get the car to run on starter fluid and you are positive that all your ignition components are good then maybe you have a computer issue or the harness is wrong. Maybe your injectors are plugged in in the wrong order. I dont know, all I know is that if your airways arent clogged then if you have spark and you have fuel then you should be running. if you have spark and fuel and compression and you still arent running, then one of them isnt going off at the right time.

I was able to test cylinder 1 and 3 by putting air in the cylinders with the compression tester tool, and I could hear air flowing, and feel air lightly coming out the valve cover and smelled gas. Only used about 10 psi.

When my car was burning a quart of oil every 100 miles because the rings and walls were so bad the cylinders could still hold (doing the same thing you did with a compressor) like at least 50 psi

Weird, my motor is a reman with for sure less than 2000 miles but it sat for a couple years. Has run good since I have had it, but with all the flooding and injector problems, all the gas may have scarred the cylinder walls. Technically the rings should be fine I would think.

Also, I'm still smelling fuel from the air blowing out the valve cover and I have new oil and since haven't plugged the Injectors up and they are not leaking.

could be valve seals, do you hear it in the intake too?

I did at first, but I think it was because the piston wasn't at TDC, as I left the air running and spun the engine over more, I eventually got it to stop coming out the intake, and just heard it in the crankcase or through the valve cover.
