Question first, context after, if you can be bothered with the detail, so:
On a sealed, built-up case, do I use the 2nd relief valve to plumb in a route to add an external filter, or can I get the gallery tapped and use a 3/8npt for Full Flow oil pump cover (GB or CSP) without opening the case up again? I'd rather tap, so the secondary is still doing what factory intended, but your experiences much appreciated...
I've not yet "popped my aircooled-engine-rebuild cherry" so am still learning, and as such please treat my naivety with the level of disdain it accords!
Bear with me on this background, but I've "inherited" a semi-built-up dual relief AS case that has the bottom end all built up by someone I trust (my father in law, no longer with us), so the case is mated and ready to go. Standard build, was going to be a dual port 1500, based on his choice of Mahle barrels & pistons. I'm wanting to keep his part of the build together, so am happy to swap the barrels & pistons for bolt-on 1641s. Had it, and 4 heads (2 twin port, two single port) soda-blasted and they all look tidy now. Engine being build needs to be 5000 miles/year, "fun" (would like to be able to maintain a reasonable speed up hills and on motorways, and still be reliable. Thinking is:
- carburettor Kit, Weber 32/36 Progressive
- Mahle 1641 barrels & pistons
- Facet pump and Filter King, so can use pump as breather outlet rather than Rocker covers
- The rest just being damned good quality other "bits"
Appreciate any and all feedback, even if derogatory!
