Break in time only, dumped the oil out of the filter and some of it was magnetic. Cut filter open and minor flakes. New 455, 30 Over. Forged rods and pistons. Polished stock crank. Please see the pics. UPDATE UPDATE - VIDEOS ADDED. Hope they work https://www.facebook.com/video.php?v=10102653166744523 https://www.facebook.com/stephen.jo...zVOLmzFPknmcpwLUWvIlrppVW4gCm1D7cx108mGI9GGoW
That's a lot of stuff. Block possibly not clean enough? Maybe drop the pan and look at some bearings to be sure. Not saying it's from bearings . Are those big chunks in your hand magnetic? Just suggestions. Lippy
What 455 ? Pontiac 455 has 3 1/4 main diameter. They need around .003 clearance. They don't like high rpm. Just watch your oil pressure and run it .
Yes, 2k but only got about 10 minutes on the run stand. The radiator on stand was undersized and it started to overheat.
Some of the metal in your hand looks like metal from turning the crank. Did you use a gun bore brush through all oil holes in crank? Machine shops turn crank, but most don't clean them out afterward.
I agree with a couple above, as big as the pieces are it looks like inadequate cleaning of parts when assembling. I'd pull the pan and plasti-guage the rod and main bearings, if they check out bolt it back together and run it.
10 minutes isn't enough time. It would be okay to shot it off, but when fired again it needs to back up to 2000 rpm for the remainder of the breakin time.
If that came out of the oil pan or filter motor needs to be taken apart and thoroughly cleaned and inspected. No way that trash is a good sign. Sent from my XT1710-02 using The H.A.M.B. mobile app
3,000 rpm for thirty minutes to break in a cam. With low tension valve springs. then after break in you install the stiffer springs. You gotta really clean a new assembly. And prelube the engine before you start it. That engine is contaminated. take it apart and assemble it correctly and clean enuf to eat from.
If there are big cast iron chips , that's from boring cylinders. Someone did not clean very well after all machining was done. The crank was just polished that would be very fine grit. It's all about cleaning. I worked at a machine shop and the blocks went in cleaner 2 to 3 times. All holes was brushed and hosed out.
Not what you want to hear but I would tear engine completely apart and check everything. Had to go threw oil pump to get to the filter which means in is everywhere in your engine.
That’s the best thing to do,,, Pray nothing got tore up, it will be obvious if it did because that’s a lot of debris. The cam break in procedure key to success is light duty valve springs. It’s a ROYAL PITA and double work. Funny that years ago it was never done and rare to hear of a problem.
A curtain brand of oil pump has been known to have chips in them. Most Pontiac engine builders disassemble oil pump and clean and lubes.
Don't tear anything more apart on it! Take your oil sample and filter to them and let them tell you what to do next. Assuming they're a "stand-up" machine shop. The less you touch the less reason they have to suspect your motives.
YES/AND NO! Yes- I'de fully tear it apart to inspect before running it. But NO- I'de take the samples of the picture shown back to the machine shop, and raise a lil hell.... Sorry- I don't care what make/model/engine that's from, that's just unacceptable..... And it's been run...... Hey- Not to piss in anyone's Wheaties, but- if that was caught in the oil filter, Just think where the rest went, and circulated through..........
