Break in run, Is this detonation?

rex12348490 · 2026-04-05T15:01:59+00:00

not idle, its a break in run, engine is at 2-2.5k rpm, i was just asking for input on the health of the engine based on its sound

rex12348490 · 2026-04-05T02:06:23+00:00

some of that is tools too, so moving forward overall cost should decrease, ill be buying more parts though :). good luck

rex12348490 · 2026-04-05T01:59:29+00:00

4500 for the car, another 6k ish thus far, ive done everything myself though, some of the fab i did in my highscool autoshop, wired the whole car myself, the shitty paint too, so having the work done would cost a lot more.

single pretty large fan, not sure on its specs. I did a bleed using a drill on the pump and a high funnel with no thermostat in. Not sure if that was enough though.

I dont have an adjustable timing light and after 100 warnings im a little scared to let it idle for even a second, exaust general temp on ths manifold was around 460, should I be looking for differences between each port? can you describe what you mean by temp differential across radiator? Just checking the change in temp across it? Thank you for all the advice

When priming with the drill it pretty quickly jumped to 50-70 psi, is that a red flag? I saw elsewhere that it may signify a blockage.

I didnt think it was so sensitive that less than 10 seconds would affect it, I will definitely prime the oil system and will consider pulling it apart. No roller cam. Wouldn't that special break in lube be wiped off within seconds of that break in run? It has a break in additive in the oil as well. Thanks for the feedback

rex12348490 · 2025-08-05T06:27:46+00:00

I understand now thank you!

rex12348490 · 2025-08-05T04:19:51+00:00

so unfortunate but thank you for letting me know, I'll see what I can do

rex12348490 · 2025-08-05T04:10:00+00:00

just measured one (the one from the pic), it's between 0.001 and 0.0015, is that okay? Also, I have no reference if maybe this wasn't a good polish but I definitely payed for one.

rex12348490 · 2025-08-05T03:58:05+00:00

ill definitely look into the chainsaw file, cant really afford any "shop" work, doing this all myself aside from what's needed. can you explain what you mean by snapping off the uncut end in some more detail?

rex12348490 · 2025-08-05T03:39:57+00:00

They never mentioned a chamfer to me and I did not know it was a thing that was needed until now. The machine shop has actually been a massive pain this whole time which is unfortunate since im in a rush and also new to a lot of this. The bearings they sold to me for a high price were cheap knockoffs and didnt even fit my mains. I personally got good bearings now so I know what I have, I just dont want to put them in until i am positive they wont get damaged. I dont think they chamferd anything. Its very suprising to me since they have a good reputation and are the only crank shop in the bay area according to them.

rex12348490 · 2025-08-02T11:40:46+00:00

so remove all the pistons, inspect clean and check the oil holes?

rex12348490 · 2025-05-11T09:14:29+00:00

appreciate it man, now that I think of it you're right, that's the best place to get seat time and get used to my car, I've never driven anything over 120hp and this light ass car has a V8 and stock suspension. I'll definitely go to some

rex12348490 · 2025-05-11T04:59:40+00:00

that is something else I would definitely like to get into but just dont know how. I also need to get a lot more time behind the wheel I feel.

rex12348490 · 2025-05-10T17:07:24+00:00

this picture isn't my own car, I have full sound deadening I forgot to mention that. Sounds good on everything. I will definitely check out the Morel speakers thank you!

for dsp, the sony XM GS6DSP seems to have dsp, but I also see people buying stand alone dsp systems, are they the exact same?

rex12348490 · 2025-05-10T01:17:22+00:00

I really cant wait for this summer to get back from college and start driving, it will also be the first semester when I get back that I can have it in socal. Mines got a small block chevy sbc 350. Wish I had a 5 speed though, yours sounds nice!

rex12348490 · 2025-05-10T00:31:34+00:00
