QUOTE(BeatNavy @ Mar 13 2022, 06:23 PM)  I agree that sucks Robert. Are you sure it's something internal and not something intake or ignitiion related? When you tore it down last time you had evidence of valve interference. Were you getting the same symptoms last time? Those compression numbers look good, so....maybe NOT something internal. Otherwise I have not clue but hope for the best. IM still hopeful as its not a catastrophic fail yet.. but the howling is seen on the first 15 min brake in and again on this build and can be heard on the video too. So internal seem likely..I will swap out he starter next as This was new to the 2056 on first start and ez to swap a Bosch in its place. Else its a bearing? I did reuse the bearings from first build as everything "LOOKED" ok and so were the journals |

Could be as simple as a nick on either the cam gear(s) or the distributor drive gear(s). Best of luck |

Is the howling noise the noise you re concerned about what we hear in the video BEFORE you turn the engine over and it sputters a little bit? The video you posted on the 12th?
@rfinegan If the key is in (I'm guessing it is as the head temps are reading) but the engine is off and something is howling, I'm thinking fuel pump. How is the fuel pressure at the engine? Zach |

To me it sounds like a dry bearing and pulls /slow the engine down till a stall. This is the sound it made just prior to my valves bending and pushrods (see first fail). Odd enough, returning the next day the sound was gone and only a miss fire on Cylider 2 (the popping was seen on cylinder one in video)
Currently it is running on 4 cylinders and no noise. I have done several leak downs and compression test. Still in the Diagnostic phase of figuring what the heck is going on. Ever day its something different and new symptoms Fuel pump is under the hood and 2-3 psi. It is relayed with the key on via the power relay on the play board. Self regulating at the pump QUOTE(VaccaRabite @ Mar 17 2022, 01:07 PM) Is the howling noise the noise you re concerned about what we hear in the video BEFORE you turn the engine over and it sputters a little bit?

Could it have been a tight thrust play? Maybe something ground it's way free enough to no longer cause noise, friction and resistance?
