On a side note,I've done so many leak down tests in the last 35 years I can say I have a handle on cylinder sealing. 20 years maching race blocks for a lot of guys that demanded low,low leakdown rates on new engines of no more than 5% with conventional ring packages. Less yet for no gap top rings. To achieve this the rings need perfect sealing,the valves must pass a vacumn test of zero leakage and of course the head gasket must be perfect. Sooooo,if everything is so perfect,why is there any leakage? It's that little,bitty +/-.030 ring gap. That doesn't do anything but get bigger. FAST. Only .0005 wear in the bore or ring face wear of .00025 will open up end gap approx.0015 depending on bore size. Soooooo,even if the rings were leaking anything and actually needed seating in time,the benefits would be negated by the opening up end gap.
he needs to make an eyebrow for it. does he have a full roof?
so big dave....what upgrades are you considering making to your rail after the sale of that collectors vw van?
i have been looking around at md4e used gear box's....they are bringing more money then i thought they should but used looking at $4k to $4500 and new you can find them all over at $5500 so hard to justify used if the gearing is wrong! i feel your pain on price tag of changing motor just did that and i try real hard not to think of what this cost me but after selling my old engine and the system, cut the swap price in half and in the end i like the additional power. the trans gearing is still an issue but will get that taken care of eventually. the new md4e, btw, only comes with a 5.14 r&p so they can run larger 1st thru 4th gears for strength, or so i have been told, also i was informed it uses a dana 44 diff and 2" narrower (flange to flange) than the bus or megasand trans. that spacing diff is what has me on hold for now as i have an a arm rear end.
