!!!!!!!!!!!!!

The short: started up my car today (for those not following, I rebuilt the engine myself and put it into a new shell) and got it to hold an idle at 1.5k!!!

Let it idle for an hour... decided might as well keep the good times going, took it out for the first little drive around... kept it below 3.5k. All good!!!! =D

Of course there's plenty to do...

About half way through the trip on a really steep hill, the coolant buzzer went off. After idling for over an hour without... so I know it wasn't a lot of air, it must just be a little tiny left at the top of the radiator... I'll let it out after I cools down and fill it to the top. =) (unless someone in the radiator filling thread tells me otherwise.. head over there in a second heh)

Mad exhaust leak. Gonna try putting the bolts tighter, but if that doesn't work I'll need gaskets... bah. This was expected... I'm re-using a few gaskets because I didn't want to wait for them in the mail.

Idle is strong, but the BAC valve is definately screwed. When I push on the brakes using the booster, I get the idle falling... blah. =/

I think the timing needs to be set better... I hear a little hesitation or "hmph" randomly like every few seconds, sometimes more sometimes less. It doesn't show up on the tachometer, and it WAS there BEFORE the rebuild... so I'm guessing it's something to do with the BAC or the timing. I guess we'll see.

I can't wait to get this thing all done, broken in, smogged (yes I plan to LEGALLY smog it lol), registered, etc.

EDIT: Thanks Ted!

And sorry I totally forgot, these forums love the pics, so here we go. ;D

Here's from the first startup, this was on New Years and lasted about 5 minutes though. ;P



I'll add more in a minute... I took all videos so I gotta screencap them.

Be careful about blaming things for hesitation and bogging problems.
This is a fresh rebuild right?
Low compression can cause all of that.
Wait at least for a few hundred miles for things to break-in, and see if the problems are still there.
Most likely they will slowly disappear...

Congrads!

congradualations!! i bet you feel really good about it, i guess just break it in and let everything seat properly. What is your voltage reading? It might have something to do with the hmph every few seconds, my friends 87 base had that idle but after cleaning the charging wire on the alternator and adding a ground wire his voltage has improved and the idle has less of that bupp..........bupp........bupp, idle. Is yours turbo? good luck

 

It's an N/A..

The voltage is good, around 15 and stays that way even with the stereo full blast.

I removed the P/S pump so I'm sure the alternator gets plenty of power to it.

And I came up with a good way to describe the hesitation... it sounds (from the exhaust) like someone hit a bass drum...you know, a kick drum.

It has that deep bassy feel to it, just a real quick "thump" in the exhaust.

Anyone know what that is?

why not just post the video?

 

Who's gonna host it? ;P

Sorry to disappoint you, but it's normal.
Someone did an o-scope print of the twin coil leadings, and it shows that one side doesn't fire every 4th or 5th time - pretty consistently.
Chalk this up to uneven combustion chamber loads - one side is in full compression with fuel and the other side is relieved of pressure with burnt gases.
Even with good power to the coils, this doesn't solved the problem.
A CDI box fires more consistently, but it will not guarantee to get rid of this "hesitation".

Well at least it's not something I have to fix then... I guess... heh.
