I'm replacing the oil pressure sending unit on my 1.7. There was no washer when I took the old unit out but I suspect that the unit was leaking and can't rule out that it should not have had a washer. AAs parts pdf shows a washer for the Temp sending unit option but its hard to tell whether it means for there to be one on the standard unit that I am using as well. The guy from AA sent me the washer just incase. The Haynes manual doesn't mention a washer but I'm just looking for some good old 914 World feed back, Nothing beats it!
Question: Should I use the metal washer or not? Thanks again! (IMG:style_emoticons/default/beerchug.gif) |

also wandering about how tight it should be. the old one was pretty tight. Felt like loosening a lug nut on a wheel.

Just to be sure I read this right - you are talking about the oil PRESSURE unit on top of the motor. That uses no washer and is just "snug". It's a tapered thread like NPT.
The oil temp senders in the taco plate uses a copper crush washer. -Aaron |

So, no washer then? Thats the way I was leaning. |

No washer for pressure sensor to case. If you decide to use teflon tape, be sure to allow the sensor to ground to the case (don't insulate by using tape) and don't let tape get into oil passages.

Yup, no washer. It's a taper thread, like pipe thread.
If you want to use a sealant, use a liquid sealant. Tape can leave fragments in the oil passage that can separate and clog passages. I haven't seen an issue with grounding when using sealant, but you can use an ohmmeter to be sure. |
