Not wanting to have to drill the block to locate the dipstick hole where it should be for the manta in the block, i did a bit of searching and found the the US Ford 73L V8 Diesel has an oil pan dipstick!! So after a bit of measuring and checking i reckoned that this would be just what i needed. So i ordered one on ebay and when it arrived measured it and bought a metal hole punch to cut a nice clean hole and as i has a spare oil pan i thought i would give it a go. After cutting the hole and doing a test fit it looks good. I just need to get a dipstick that fits and then when the engine is fitted and fully filled with oil i can mark up the dipstick for the full mark.
