55' 324; noise low front...

Describe the tick or thump. A stuck lifter tick is usually a higher up noise and sometimes tinny compared to a rod or main. Did you replace the lifters on the rebuild? By chance did you use SBC lifters rather than Olds lifters.
I would first give the engine a good flush and filter change, then try a different oil.... Tedd

55's noise low/front...
Hi guys... first thank you for your inputs... The noise is constant when running... we thought it was a lifter, then 4 mechanics standing under the car...
thought the noise was coming from the oil pan !!!...then the someone pulled the oil breather cap off n said it could be heard very good from the
oil filler tube ?????????????????????

I have it on good authority, that you can put in the rocker shafts upside down. The problem with this is the hole for oil lubing the shafts is in the wrong place when that happens, can affect lifters. I think the hole should face down, so get the oil up into the shaft. Not sure if this is the cause since the engine was freshly rebuilt, might be worth checking. I might also be describing it wrong, but again, worth checking.
I think Ted can give more details.

Thank you for posting this, when I rebuilt my rocker shaft I indeed had it upside down, I tore into the engine last night after reading this post, it certainly does make a difference, there is visible wear after only 300 miles on the rebuild, enough so that I will probably buy another set of new rocker shafts. No mention of it in the service manual, as a matter of fact it states to not remove the rocker mount with the dowel pin.

I made the same mistake on the 54 I had. I finally talked to Tony at Ross Racing and he told me they faced down. I then bought a set of assembled rocker arms and shaft from him and no more problems. No where in the factory service manual does it tell you which way the shafts go.
