Lonzo's 88 Coupe 3.4 DOHC build thread

[Aaron]

That is a concern. I'm hoping the relatively low power levels, and the stiff 4 lower mounts will help avoid any problems. If it bends, I'll have some gussets welded in.

[Jinxmutt]

maybe the glass just has a safety factor built into it?

The car has been pretty much done for a few weeks now, but today I took it for a drive to fill it up with gas and reset the gas gauge. On my way back I took a video of it at full throttle, which was awesome. Unfortunately one of the camera shudders stuck closed, so the picture is gay. Also, towards the end of the run I blew a coolant line off. So now his motor is drenched in coolant. I'm not sure which line it was, I'm going to repair it next weekend. I'm not sure yet if I want to put that video up

Here are the pics, before the green polka dot paint job:

[Aaron]

Alright I'm going to put the video up since you can't really tell shit hit the fan.

The hesitation off the line was the tires starting to spin, and me letting off but getting back into it right after. I don't like to sit and let the tires spin/hop in the Fiero, it's not good for the drivetrain. Sorry for the crappy picture, the shutter stuck closed on the camera. The chirping sound at the end of the video is not me driving into a curb, it's me pulling into a parking lot and his suspension squeaking (It's noisy). I'm kinda pissed about this coolant line blowing off. I'm not sure which one it is, but none of them should have. I know the car wasn't fully up to operating temps yet, I did this on purpose so that the T-stat was closed, and a 6500rpm run would maximize the coolant system pressure. All of the lines look to be in-tact.

So yah, this is what a ~220-240hp Fiero at 6500ft altitude feels like

I found the coolant leak. The rubber line that connects the metal heater core feed line to the metal line off of the lower intake split on the side. I'm going to replace it with fuel injection rated hose, which will be sufficient.

[The Dark Side of Will]

Was it new?

What's wrong with new coolant hose?

[Aaron]

No it was not new. Might as well go a step up, overkill is usually good enough.

[p8ntman442]

yeah, fuck doin it right the first time, do it overkill the second time.

[Aaron]

Here we go again. I guess I should just replace every single component on the car that's rubber, on the if come maybe that it could fail.

[The Dark Side of Will]

I'm not saying that... yet.

I just don't see what's wrong with new heater hose. Can you even get fuel hose in that size?

[p8ntman442]

I stood by you on the FP so shut the fuck up. To not inspect all the hoses though is lame. Dont tell me a perfectly good hose blew on the first test drive. That bitch must have been squishy, which would have taken 5 minutes to diagnose.

GTFOver yourself.

There's probably nothing wrong with heater hose, but if I can get a higher pressure hose, then there's no reason not to. The line is only 2" long, so my parts store will just give me the line anyways.

Who said I didn't inspect it? The hose was in great condition when it was put on, otherwise it wouldn't have been put on. Where the fuck did you get the idea that this was the first test drive? I've been driving the car, at least 4 times a week, for the past month. This is just the first time that I went to a sustained high RPM, when the T-stat was closed. And I did this, so that if something couldn't handle the demands, it'd fail now instead of when Lonzo is behind the wheel. Figuring you're too fucking stupid to understand this, the pressure demands of 6-8 seconds of 4500-6500rpm, with the T-stat closed, are pretty substantial. Enough to blow out copper soldered heater cores in fact.

[p8ntman442]

and you wonder why your name is auto corrected to retard.

You do know that copper soldered heater cores are good to over 1100 psi, yet heater hose is only good to probably 250psi.

your so full of shit its coming out your fucking mouth, eyes, ears and nose.

old dry rotted spongy hoses blow, good hoses do not. you reused an old coolant hose and now your going overkill to fix it for no reason at all.

[The Dark Side of Will]

Who said I didn't inspect it? The hose was in great condition when it was put on, otherwise it wouldn't have been put on.

Obviously not. New hoses take that treatment and don't blow.

Overkill is seldom a smart way to solve a problem. Keep blowing fuses? Just overkill it... put a bigger one in there. Yeah, that's smart.

Exercise some evaluation and some judgement.

[p8ntman442]

Before the trash man comes, go grab the old hose and mail it to me. I'll determine if it was in good shape or not.

[Aaron]

Turns out, I did use a new heate hose when I put the car together. It looked brand new, except had a bulge and a split in it.

When I put the A/C lines in, they pushed the heater core line down, which caused the rubber connector at the intake manifold to twist into an S curve, which with the heat and pressure split it. So I bent the aluminum outlet form the LIM to match the line's new position, and bought a new section of heater hose to use as a connector. The Auto Parts Store actually gave me the new section for free, since it was only 2-3" long.

How does a hose with a bulge and a split look "brand new?" Are you trying to say it was brand new, but it split? And what I'm getting from the rest of that is that while you may not have fucked up by reusing an old part, you fucked up the installation, so it's still your fault.

The hose aside from the damage was new, as in, it was new when I installed it. The writing on the side of the hose was clean and clear, and the line was in new shape, again aside from the damage. The original installation was fine, but when I put on the A/C lines, they moved the coolant hose which caused the damage. Being underneath the car to do the A/C lines, I didn't catch that the coolant line moved. I never said it wasn't my fault dumbfuck, that's why I paid for the new part, and I installed the new part free of charge. Fact is, something went wrong, and I took care of it.
