Ok now im thinking i did the conversion on my mk2 the vr engine is an early vr dizzy style i read on gruvenparts that there are two dipsticks one gor early models one for later.the early models use the orange plastic piece on top of dipstick tube im sure when i first stripped engine down the dipstick was broken and as i have a spare obd2 engine i used that dipstick which would be shorter and now even more shorter with the orange plastic piece being fitted.id better get some measurements and part numbers from what ive got fitted
