I took my injectors out of my '72 1.7l over the weekend and found that the PO used RTV gasket sealant to seal off the #2,#1 fuel injectors (IMG:style_emoticons/default/dry.gif) Upon further inspection, I noticed that the stepped o-ring/grommets where missing. I purchased an injector o-rings set from my local auto store thinking that would be it but nope. Can someone please tell me what that o-ring/grommet is called and where I can purchase them?
It's placed in the bottom opening of the intake runners where the injector is installed. |

I think what's throwing me off is that the O-rings that I posted pics of looked nothing like the fuel injector lower seals that I just purchased. I'm just presently learning through someone else's ghetto rigging this 1.7l. Now it makes sense why the the #2 and #1 injectors had only RTV gasket seal sense the previous owner just scraped together whatever seals they could for the present injectors.
I'll be placing the new factory replacement upper and lower seals on my injectors tonight. I'm surprised I didn't see any fuel leakage. Well, One Fix At A Damn Time! Purchased car back in May and haven't even driven her yet. |

They look nothing like the lower seals you purchased because the ones that were on the car had 40 years of pressure and heat from the heads applied to them. They all wind up looking like that eventually. The stepped shape is what they look like pressed in place, those ones have just been baked so long they no longer spring back. |

Makes sense why they fit so perfectly in the heads. 40 year molding process! |
