Humble Apologies,
Perhaps my question was not stated correctly.
'LA'-BLOCK castings ,
Can the BLOCK be machined to install
--Oil Jets--for PISTON cooling ???
(numerous diesel & gasoline turbo engines)
Thx
If your talking about something like what the boosted third gen hemis and LS use in the bottom end, I think it would probably have to come from the back of the block through steel hard line across the bottom and outside perimeter of a windage tray and tee off under each cylinder. Those squirt tubes that go in a DXC hemi block are only about a 3/32 of an inch and pinch down to a point on the end. It definitely would take some pre planning but if you used brass junction blocks and 1/8 inch or smaller line to make a line/jet out of... just throwing an idea out there, FWIW, probably not a whole lot of help. But I don’t see being able to tap the oil galleys under each cylinder like in the newer engines with the banjo fitting and hollow bolt either, as in this example...???Anyone???
Any help appreciated
Thx!!
And of course drilling the upper bearing shell, too. I get a little queasy thinking about stealing oil right from the main bearing in something that is pushing enough boost to need continuous oil spray to the bottom of the piston. Maybe not so bad for the mains but the top bearing shell in the rod is always going to be loaded under boost. But, it’s probably going to better than a bunch of hard line snaking around under a boatload of vibration!
