1. Everything went to the hot tank bagged and labeled but these came back with other MISC pieces that did not make it into the bag they came out of. Where do they go? 2. What is a good break in oil to use when I fire this rebuild for the first time? Thanks in advance for the ***istance. Z
now you got us wondering, what the invisible picture is? Modern oil will probably be fine, the lifters are pretty big on those things!
They look like they're related to a door latch or something...not an internal engine part. But I could be wrong. I don't remember seeing anything like that in the 292 I overhauled last month.
LOL that could very well be true. I picked up a block for a guy once and the machinist said, "Tell Clarence here's a bunch of bolts he never pulled and handed me a bag." We looked at the stuff and decided that it was floor sweepings but he was correct it was stuff that Clarence never pulled. LOL Note: The machinist in question and Clarence were old school chums.
We found the the other parts in the MISC. bag all belonged with the engine but no clue with these two. Do they have anything to do with the rocker oiling system. I am thinking of going with the pressurized system Tim McMaster runs; any thoughts on this? Z
why change it? If you replace the cam bearings, and run modern oil that doesn't sludge up like the old stuff, you'll be fine. The rockers don't have any parts like that.
Those could have been anything from anyone's stuff that he found in the tank. Hot tanking is not a pure science and stuff gets left over. I had a bunch of Harley parts hot tanked once, when I got the boxes of stuff home I found a pet**** for a Limey in my stuff. I was going past the place the next day anyway so I just stopped in. The old guy said, "Thanks kid, some fella had his fuel tank tanked and I'll bet this is the piece he said he didn't get back."
Your being psycho****yzed by a machinist. Their short round pegs with square hole's. Your The****** notes state. "Delusional and will not return to ask"
There is an oil hole in the block that is supposed to line up with a matching hole in the head. It feeds oil to the rocker ***embly. Sometimes they don't match up very well, which is one reason Y blocks had a reputation for plugged oil feed. The cure is to port match the holes using the head gasket as a guide.
There is a channel in the surface of the head that the oil flows through, to get from the hole in the block, to the hole in the head that feeds the rockers...it's plenty big for what it needs to do. But it is prone to getting plugged up if the oil cokes or sludges. That is not so much of a problem with modern oils, and especially if you add positive crankcase ventilation. There really isn't any need to modify the stock rocker oil system, if you do the work required to get it back to it's original working condition--clean oil p***ages, fresh cam bearings, and rocker arms and shafts in good condition.
It just isn't true that there is no need to modify the rocker oiling system. Tim has come up with a very simple and effective way to pressurize the rockers and ensure good top end oil flow. He did that modification when he built the Y block for my RPU and he has a couple of good you tube videos explaining it and showing the results. He has proven it in his race and street engines.
really? there are no Y blocks that are still running, that don't have this mod? I find it hard to believe. Heck, mine seems to be doing fine without it.
