Chad's 68 Camaro V3.0 build. LS3 & TCI goodies

[Flash68]

Regardless Chad this is at least some positive news that the motor is in healthy shape. That's progress at least. Thinking positive for you.

So are they shipping the motor back to you now or in a holding pattern?

I didn't have an oil cooler installed in the car so it's not that.

If your relying on your guage, and have used more that one guage, i've seen guage defects, in other words, same guage used but manufactoring defects in design or production giving you a false read. Also, having just done an LS conversion in my 70, the computer does alot of weird stuff....but iirc, you had a mechanical read with low op?

been waitin for an update from you, love your car, Mike

Mike, I used the ECU with its own sending unit and a proven autometer gauge and both read the same. Besides reading the same they both read a huge pressure drop as the engine oil reached operating temp n

What fitting sizes and hose sizes are you running because that could be a FLOW issue...

Yeah I agree 1" is too high. I measured the pick up back when exploring the problem and don't recall it being so far off from the recommended 3/8". No oil cooler so don't think tht is impeding the flow. Also I tried a different pan and pick up that was shipped on the motor and had the same symptoms.

Mast will ship it back but gave me the weekend to think about it in case there is anything else I could think for them to check. It doesn't make sense to me. I can't think of anything that explains this.

As I understand it, you have no external oil system plumbing, but Mast plumbed in an oil cooler on the dyno. How did they run the engine without the oil cooler - an external cutoff with the oil cooler plumbing still attached to the engine, or did they uninstall the oil cooler plumbing and run the engine they way you had it in the car? If they used an external cutoff to take the oil cooler out of the loop, I'd ask them to run it on the dyno exactly as you had it in the car.

A few other thoughts:

Did Mast run the engine using the installed sensors for their oil pressure readings?

Did they use your ECM or a similar ECM?

Did they do anything about the oil pickup, even a remove and replace?

Did they change the oil?

I will have to ask but they did mention connecting the manual oil pressure sensor to the port I created in the oil block off plate at the oil filter adapter location for my oil temp sensor.

Yes, they ran using the oil pressure sending unit behind the intake that I shipped them the motor back with. The also ran a mechanical gauge to verify the sending unit.

They requested I send the ECU back with the motor so I assumed they used my ECU but I will ask.

I'm not clear on if they modified the pick up but they did remove it to both inspect the o ring (which they said looked find and installed correctly) as well as to pull the caps on the mains.

Yes they changed the oil using rotella 15-40 which happens to be exactly what I used on my last oil change (one of their recommended break in oils). Though I did verify they used the existing oil filter I shipped the motor with.

Thanks. Will let you know if I hear back on the plumbing and ECU questions.

Any updates Chad?
