I just now realized this new engine that I have been piecing back together over the past few weeks isn’t the 1.8L that the PO said it was. The engine code on this engine is EA050723, which if I cross checked correctly is indeed a 1.7L
My issue is, I have been transplanting my old 1975 1.8L Ljet fuel injection parts on this 1.7 block. Can I run Ljet on this 1.7L engine? What obstacles am I up against? Is my 75 1.8L relay board interchangeable with the 1.7L setup? |

Okay, this is all good news. One last thing, The head vents, can I just use vacuum rubber caps things on them? I was thinking about using them, and putting a hose clamp on it. Should I be worried about head temps melting them?
 Also, was there a rubber seal/o-ring on the top of the dipstick? Seams like a good place for vacuum leaks. |

Seams like a good place for vacuum leaks. Those rubber caps do seem kind of melty. You could stub short sections of hose over the vents and plug the hose with a bolt sized to match the hose. I checked the PET diagrams for 1.8 dipstick the dipstick profile showed a bulge that might be grommet or flange on the dipstick located beneath the dipstick cover. |
