I was browsing the samba, and saw this thread with some really good diagrams of the dual relief oil system. I am not sure if the measurements were from a type I or what, but it was really good to see a good diagram of the oil system with some actual pressure measurements for different engine conditions and temps. It would be interesting to see what comments you guys that are highly experienced with the type IV engines have. JoeO

thanks joe, this is what i was looking for but couldn't find before finishing my build. i had 30mm pump questions about the excessive volume (in reality pressure) causing it ti bypass the cooler. this test varified that. it was also using 10 x 40 i think, lighter than 20x50 anyway. i noticed all sorts of hot running complaints with 30mm pumps. i took a crap shoot and shimmed apx. .040 under the oil relief (not control valve). my thought was to keep to oil passing through the cooler, and yes on our hot central valley days the cht's are VERY good. i think it helped.
correct me if i'm wrong the drilling of the oil control passage would help the oil return to the case quicker instead of flooding the heads... it also would be bad to shim/stiffen the oil control spring for above stated reason? actually if you have good pump volume/pressure and within spec. bearing clearances then a drilled oil control and maybe even lighter(?) spring pressure, it would be good to get the oil back to the pump. after all most oil systems dont have a check at the END of the system just my wacky thoughts (IMG:style_emoticons/default/idea.gif) |
