Good Morning CGs!

Happy Sunday to everyone. Hope you've been enjoying the weekend. Happy belated birthday to Sue. Hope you guys had a nice dinner.

Update on the car status. My buddy can over Saturday morning with his borescope. Didn't see any unusual scoring or damage to the cam. I was able to get a finger on it through the lifter bores and it felt smooth. The first good news I've gotten about the car. So a set of lifters, gaskets, some assembly lubes, and an oil change and I'll be back in business (hopefully).

Hope everyone has a great day!


I would check the push rods on that cylinder, possibly one is bent?

Good Evening CGs!

Started working on the Corvette today to get the new rocker studs installed. Got the head torn down and cleaned up, new studs installed. Put the pushrods back and ruh-roh. Something wasn't right. #3 pushrod was sitting too low in the head. Fuck. Lifter is collapsed. That means the while top end has to come apart. New lifters and most likely a new cam. I think the valve is still good. I'm in a pretty shitty mood. Sorry.

Hope everyone had a great day.


That sucks! Any idea why the stud broke? Hope the damage is just the lifter.

Well, I hope I don't regret this so here goes. I've been driving the car around town quite a bit in the last month. Still had a small "dead spot" sometimes around 40 mph, so I replaced the original TPS. Everything has been perfect since that. I really think there were several things going on that got a little aggravating. (1) the broke magnet in the pick-up coil possibly, (2) poor connector fuel pump harness/motor (3) tps dropping out. This was not a well defined thread but possibly might help someone later. Main thing is "don't give up"!

Past due for a update on this. Well, after replacing the pick-up coil and driving around longer it started the same problem of intermittent stalling. Car was parked for the last several months while I continued looking for the problem. Fuel pressure started getting low at idle,32-34 lbs. Voltage to the three wire connector at rear connector was correct. Pulled the pump assembly last week and I think I finally found the problem. Hot wire and connector at the pump was corroded badly. Insulation was even melted on the wire about 1/2 inch. I don't see how the car was even running with the condition of that connector. Pump connector was burnt some also. Installed a new kit from Racetronix, so far so good. That was a new ACDelco pump I installed back in 2011 and did not notice any problems with the wire or connector then.

I installed the new ACDelco pick-up coil #D1945X yesterday. Everything went well as I've changed many of these over the years. Car started up perfectly. Still have to set the timing and a couple of small things to button up. Old coil was really rough looking, even the magnet was broken in four parts. I hope that was the problem, but I'll have to drive it around for a few weeks. Will update later with any more news.

I've been too busy with other things to really get more involved with the car. But, it will crank and run with timing connector disconnected. It does the same thing with that ECM I got from you, so that shouldn't be the problem. Had to crank\start about 30 times, but it did finally do the crank-start-die-crank-start once.
I'm going to replace the pick-up coil when I get some spare time, should be this week or next.

This is so intermittent it will catch me by surprise. Might happen twice in a day, might not happen again for a month. I've been able to "monitor" fuel pressure once when this did happen. I just got lucky and already had the fuel pressure gauge attached, pressure stayed high 40's during crank,die,re-crank & run with no change. Not sure about injector pulse during this, have not been able to check yet. Have not been able to notice tach yet, but am trying to watch this every time I start car up.

Yea, fuel pressure is correct. 42lbs instantly with key on. All injectors ohm at 17.2- Bosh III type.

I was just curious about that sentence from the FSM. Just dosen't make any sense to me.

I can read and understand a FSM fairly well, but here is one paragraph that I just can't follow.
1989 model
Page 6E3-B-3, top right of page.
"If engine starts but then immediately stalls open distributor, set timing connector."

I fully understand what the timing connector is and where it is, and it is not inside or around the distributor. And the open distributor part?

I'm hunting a cause of mine starting up fine and then sometimes it will die immediately.

I've read and re-read that paragraph a dozen times and it still does not make any sense to me.

Any thoughts

Joel

One more thing arrives: some rubber splicing tape.

10 days and 1 weekend to go.




I've got to ask, what is this rubber splicing tape.

Not exactly. Forget about the oil pressure sensor and the fuel pump, except as only a back-up system.

When the ECM commands the fuel pressure relay to run the pump, it does not matter if there is any oil pressure.

The oil pressure ONLY comes into play when the relay is bad/broken and no power is sent to the pump.

Hope I'm not confusing you with all this rambling.

Joel

The oil pressure switch in regards to the pump running is for a back-up system only. When the engine starts after the initial "pressure build" the pump stays on and pumping. Any unused fuel is returned via the fuel return line from fuel rail and fuel pressure regulator.

Actually the oil pressure switch is by-passed on a correctly working system. The ECM will activate the fuel pump relay for approx 2-3- seconds at first turn of key. If this fails, then the oil pressure switch will power the pump after approx 4-6 pounds of oil pressure is built when cranking the engine.

This is for a L98, can't remember your model.

Fuel Pressure Regulator -L98

Just passing along some info on this item.
My 89 started having a slight stumble on start up a few days ago, checked fuel pressure and it was low at 36psi. Also the pressure would drop to zero the instant the pump stopped running. This is what was causing the stumble.
There has been alot of problems with different brand name regulators from the big box stores, mostly complaints about not holding pressure. The main problem is the "button" that seals inside the regulator housing. The machine finish on the button is done poorly leaving deep scratches on the face of this button. I have seen many different brands with this condition.
I ordered a AC Delco 214-2156 and was surprised to see a much better machine finish. It wasn't perfect but better than the other brands I had looked at.
Even with the better finish I decided to polish it some myself. Spent about 45 min with 1500 grit then 2000 grit and got a really good smooth finish. Installed it,turned key on, pressure built to 42 psi instantly, and held there for 20 min before starting a slow decline. No more stumble!!

Thought this might help some one with a similar problem

I agree with the "function" of the above grease, but keep one thing in mind. The smell of some products when used in the cabin will be strong not very pleasant.

What Matt said. Also possibly the inter-lock cable that connects from the shift assembly under console up to the steering col. There's a solenoid at the shifter that acts up sometimes.

Actually this is the same thermostat that was in the motor before the pump change, and I did drill 2 holes in before install about 4 years ago. And yes car was on ramps that I have been using for the last 20 years, (4) four stacks of 2 x 8's.

I've been wanting to change the thermostat to a 180* just because of the fan cut on/off changes I made several years ago. 215*\199* . I'll just go ahead and change the thermostat next week and start from scratch on the bleed.

Thanks

I have burped this thing at least 20 times in the last few weeks. I even ran a lever type rad cap for several days and drove the car around some, every time I stopped I would release the lever trying to get any air out.
Never had any problems with this car burping before this. I've had the coolant system opened many times over the years, and NEVER had this problem.

Now, I can't say 100% there is no air trapped somewhere in the system. I did change all the heater hoses when I installed the water pump, so this did introduce even more air into the system. Seems like a lot of people run these high flow pumps with no problems. Some people have reported problems similar to mine.

Just reading up on these "high-flow/balanced sleeve" thermostats seems logical that they could possibly help this issue, but they are all China made crap. At least the Stants claim they'er USA made.

Thanks for the replies

Any experience, opinions, etc. with this product? I've never used one of this type, always the Stant Superstat.

This will be for my 89 with a Edelbrock #8815 water pump.
I installed this pump several weeks ago due to my original leaking out the weep hole. Temps were good with old pump, usually 194-200 at light cruise at 45-60 mph and in town also. Have a 195 thermostat now, with coolant fans set to run at 215*, off at 199*.

After the Edelbrock install, temps are about 10*-20* warmer.
Temps also spike quickly and go back down while just driving along normal. Did not do this before.

Thanks
Joel

Merry Christmas!

Shorts and T-shirt weather here, and warmer on Christmas day.

Hope everyone has a safe and happy season.
