New build spitting embers from headers

[dan468]

Just started up the 454 in my 68 pickup. Everything seems very smooth aside from some sparks or embers coming from the exhaust (open header). Could this be normal? The headers are new too. I wonder if the engine is sloughing off debris or there is actually metal to metal contact.

What do you guys think? Even if it was metal to metal, where would this occur? I'm experienced however this makes me a little nervous with a $$$ motor so I'm taking my time.

Thanks!!

If it starts and idles with good, consistent oil pressure, without any odd noises, my thought would be garbage in the headers, particularly if they're new (?)

I agree. I have put many new headers on and seen something like this.

[dan468]

Yes, they are in fact, new headers. Thank you for the responses, much appreciated.

If it was metal to metal I think you would here it .

Might as well pull the oil filter and check for metal shavings. There probably aren't any but you will sleep better at night.

I don't suppose you blew shop air through the header tubes did you? I Think you may have stuff in the header you will find all kinds of junk in there. If it is in the motor it will quit doing it soon. Sorry bad time for bad humor. I do hope all is well and it works out for the best for you. jim

Ya I was thinking the same thing. If it's the motor it will let me know soon enough
