18r-gu modifications and info
Sun, 02 February 2003 12:07
i understand that an 18r-c oil pump has low volume, high pressure and the 18r-gu has high volume, low pressure, im wondering, is there any problem in transferring the oil bypass valve from the r-c and putting it in the r-gu making a high pressure high volume pump? i can only see advantages such as allowances for a turbo later. would it twist off the oil pump shaft from too much torque?
also the manual i have is a bit useless for infomation. it fogot half of the specks and the other half is wrong anyway (yanky manual) what is the standard oil pressure for the 18r-c and 18r-gu engines?
does anyone know how to get rust off springs, con rods and cranks without damaging the bearing surfaces? one fella i talked to said "just sand it over to get the loose stuff off and leave the rest on. it wont matter" but i kinda dont like the sound of that idea. any thaughts.
Depending on how bad the rust is,
1.conrods just sand it off or if its only surface rust use some scotch brite and turps or kero or wet and dry and kero
2.crank. same as above unless it has pits then a grind is in order. I guess its up to you but if the crank has pits in it i would probably throw it away and start again theres plenty of 18r cranks out there that you can use.
