    Engine Ticking Noise

    Mentioned 1700 rpm. My 88 with Delco ignition goes into OD/lockup at light throttle at 1250 rpm/45 mph and is smooth
  3. Today
  4. A few years ago I experimented with a pair of 22" monitors, full sized keyboard and mouse connected to a smartphone (Samsung Galaxy). Worked just fine but no-one was interested.
  5. I logged in on my Android Moto G TracFone and had no issues. I'll likely continue to use my PC because of my 19" monitor and regular sized keyboard, but the smartphone capability to access the ROJ and maneuver within the site is impressive. Thanks Ronnie for all that you do to keep this site going and updated.

    Thanks. Good to know. I'll avoid posting that photo again. I have a photo of just the broken rack that I should have posted.

    I am one of those guys who sticks with original parts whenever possible. The junk yard idea is a good long shot..............

    Engine Ticking Noise

    Maybe the transmission shift modulator keeping the tranny in the wrong gear, lugging the engine?
  11. I know it looks different. I think it looked better before on my desktop but I'm getting use to it. I think it works much better now on my cellphone and iPad than it did before the update.

    Do they have one in a different color that you could simply paint, or do just not have any? Have you looked into auto salvage yards around the country? Car-Part.com--Used Auto Parts Market

    Engine Ticking Noise

    I had to go back and reread this thread. I thought there was a comment that it could be heard, occasionally when free revving it, but as of now, it is only under some load. One way to see if the engine is hearing knock, or some other noise that might retard timing, drive the car in diagnostic mode and watch ED17, Knock counts. It is normal for some knock counts to register just from startup noise, so don't worry about the number that may appear there, this is normal. The thing to look for; is the number increasing during normal driving, specifically when you hear the sound, or the engine seems to struggle. Has the fuel pressure and delivery been verified? I know we headed off in the direction of ignition, but I believe you mechanic questioned fuel delivery way back in the beginning.

    53% throttle should be enough to go into Power Enrichment and unlock the TCC.

    BTW "gnition just spins" do you mean the key turns and nothing happens or you can hear the starter motor spinning ? If the latter, is a common problem, the Bendix is stuck. May just be able to hit the starter with a hammer.

    Could you post the part number? I would like to order one for my inventory. Cheaper then buying a column at the local U Pick.

    Thanks for responses guys, this is exactly what the problem is. Fortunately I had the car at a repair shop for maintenance when it broke. They took the steering column apart and found it. Ordered the $13 part from a Chevrolet parts warehouse and said it might have 2 hours of labor in it. I can't believe these parts are still in stock. Thanks to everyone here.

    Searching for an upper interior windshield garnish molding in slate gray for a '90 convertible. Have contacted Jim Finn and Marc Barker with no success. Any help would be appreciated.

    THE REATTA LOUNGE

    Yeah, when I was running methanol in my motorcycles with high compression a lot of ignition timing I learned that they ran better when I sharpened the side electrode with a file. Had to do that pretty often because they eroded quickly compared to a stock plug. I learned about doing that in one of the bike magazines. If the point was too sharp it would cause the engine to ping due to preignition caused by the point overheating. Then I read about the Nippon Denso u-grove plugs that worked just as well, lasted a lot longer and didn't need to be filed. I think the edges of the U shaped grove in the side electrode did the same thing as filing the end of it. I think the same is true for the platinum plugs that have the small wire center electrode.

    Engine Ticking Noise

    I'm hoping it's just something very loose, it only occurs at mid-high RPMs and under load. It's hard to say if there's really a power loss, I don't like gunning it around with a mystery issue in the engine to find out. Idle is still totally normal, though, and if I coast at higher RPMs there's no sound.

    Engine Ticking Noise

    I admire your perseverance, winter mechanic work can be daunting. So this is a sound issue and the performance of the engine is okay? It makes this noise no matter if sitting still in park or on the road and under load? I have had heat shields and other sheet metal stuff vibrate but usually only in a narrow rpm band. A helper would certainly help look, pinpoint, maybe use a stethoscope on various areas while running. I think there are some sound and vibration phone apps available to maybe help nail down a frequency for the sound.

    THE REATTA LOUNGE

    The article actually mentioned Ford doing the single platinum plugs which works unless installed on the wrong side, which would make it worse. Also stated that the aftermarket solved the dilemma by only offering double platinum. Pretty much idiot proofs it. I don't know if reversing the battery connection to positive ground would reverse the secondary spark or not? In the diagram provided, the primary and secondary directions are opposite each other, but the article stated the direction of the winding decided the polarity via some rule I don't understand. I figured I didn't need to know why as long as we had one of each in a coil pair. I believe you are correct that the platinum needs to be on the receiving end of the spark to minimize erosion. The one thing that I am pretty sure of, and is true in any spark, is that it initiates from a sharp edge, or point, more easily than a blunt or flat surface. I imagine that is why some of the AC Delco Rapidfires had the serrated center electrode? Frankly, I never used platinum plugs in my Reatta either, but it was mostly because they never stayed in the engine, or the engine in the car, long enough to matter. With no platinum at all the wear would still be relatively balanced, but perhaps more rapid. I do remember my school Honda had one coil for two cylinders, but it wasn't a 305 Dream. Way too upscale for me.

    Engine Ticking Noise

    Alright, finally managed to crawl just above the freezing point today. The bracket I picked up was correct, but had absolutely no hardware, and the holes the coil screws go into were untapped, so I found some hardware that would work (stainless flat heads just barely worked) and tapped it with a metric tap at work. Went in and checked the plugs against the proper firing order. I'm more than a little confused how this weird mixup happened, but I labeled the plugs with the correct coil numbers. Threw on the Delco ICM and coils, trimmed the three coil screws closest to the engine because there was no hole on the engine mount for them, and she fired right up. The junkyard parts are good, at least. Went for a drive through town.... And the problem's still there. She sounds growly at around 1700 RPM and up still. I don't think it's a hole in the exhaust, because I should hear that even when idling. I'm gonna stop by my mechanic, at the very least he might be able to spot something under the hood (no helpers to rev the engine for me sadly, and I don't want to grab a brick).

    I remember those photos so there must have been a thread somewhere? I didn't look under brakes and suspension🙃

    THE REATTA LOUNGE

    Excellent discussion. I'm certainly no expert on this but I'll put in my 2 cents. I think I can explain that by looking at your diagram. On one spark plug the spark jumps from the center electrode to the side electrode. On the other spark the spark jumps from the side electrode to the center electrode. The platinum needs to be on the electrode that would erode the fastest. I think that is the electrode that receives the spark but I'm not sure about that. If they had applied platinum to both electrodes it wouldn't matter. I guess they saved a penny by applying it to one electrode. I think the battery polarity would matter because the flow of electricity through the secondary would reverse if the battery polarity was reversed, causing the electrode without the platinum to be the one that would erode the fastest. I think all the above would apply to the 3800 but the difference is platinum plugs weren't specified by GM as far as I know. Maybe that is the reason auto parts stores offer aftermarket double platinum plugs for a Reatta. With those you would have the the bases covered no matter which direction the spark was jumping.

    Ignition switch

    I don't remember writing a how-to guide for replacing the ignition rack but it's possible I did. There might be something on the forums about replacing it. I think it was decided that the easiest way fix it is replace the steering column. This is the part that breaks if that is indeed the problem. Broken rack is on the top. Good one below it.
