Yes the dipstick is on the opposite side, but if you look, there is casting to allow the dipstick on either side, and there is just a welch plug stopping whichever isnt in use. The sump and pickup are the same, but the 18RG oil pump has higher flow. The pistons will fit... until you try running the engine. putting either set of piston to the wrong head will cause valves to touch. Lower timing chain, sprockets, guide and tensioner are the same, so is the lower sprocket for the upper timing set. Auxilary shaft is differnt, and there is an oil pump drive in the 18RG where the 18RC has its dizzy. Dizzy is the same tho. timing cover is different, and there is an extra dizzy drive gear goes on the end of the aux shaft. As for the crank and rods, the crank was better balanced... and i believe hardened as well... and the rods were also stronger. There was also a crank case breather for the 18RG and the original fuel pump was rated for a higher flow. in all, not much from the 18RC fits the 18RG summary, bits that fit sump oil pickup block casting lower timing set upper timing lower sprocket dizzy oil filter housing front and rear backing plates dipstick(with relocation) piston pins. Cheers, Owen bolt on stuff like alternator, starter, a/c etc will all fit [Updated on: Wed, 28 September 2005 02:54] [Report message to a moderator]
