I think I'm with steve on this also. The only reason he even posted anything about the dipstick is because the op did.
He didnt just hear some random question and say "check your dipstick"
Steve knows alotb about these cars and knows that the fpr is very much near the dipstick.
When the op asked a very vague question with little detail...
And bare with me here if with little information someone said they think their fpr is bad and smell gas on the dipstick
and didnt confirm the exact place of smell.
Most anyone who owns a m20 engined e30 probably would have assumed the same
