So I did get a few things done tonight. I went to the hydraulic shop and had them silver soder a -6AN fitting onto the oil feed line. Then I got a -6 - -4 adapter. A -4 would've been ideal but the size of the fitting would've required it to be drilled out that it would leave too little matterial. I generally CAN'T STAND adapters, but I can live with this. Note - this is not the actual line I'll be using..... I ordered an all black fitting to go along with the theme
Something else I decided to try, No more stock fasteners. The last motor I had I either powdercoated or painted all the fasteners. It didn't last. So this time around I'm changing everything out to be either a stainless acorn nut, or a button head. It's also been brought to my attention that I'm getting old and grumpy. Little things are starting to piss me off, like different length fasteners. So I studed the front cover with stainless and loctited them in there. Now all I need is a handfull of acorn nuts and washers. Should limit the grumpiness a little
This porting was already done. It always surprised me how little time Mazda spent on the oil system. I think this 1/2 mod is something that alot of people over look when building an engine. Sorry if this makes you break the engine apart again vex
Something else I thought I'd try with this build. I never liked the fact that there isn't a positive seal with the oil pump. Yeah it's machined, yeah people never seem to have a problem with it, but wouldn't it be nice if you were a little more certain about the pump not pulling in air or pumping out oil? I thought I'd give this a try. A good friend of mine has a CNC mill, he accepted my challenge and this is what we have.
Insert the o-ring, apply a smear of hylomar on the OUTSIDE of the ring only, this keeps it from getting into the pump itself, and we should have a pretty well sealed oil pump. We'll see though. I'd like to see 30 psi @ idle as opposed to the low pressure warning light flicker when she drops to idle. That always causes me a little concern. Meh, we'll see.
