1998 summit

Buddy just picked one up, sent me these:
The 90 on back of engine (mag side), is this a missing oil line? I have no experience with 670's.
Thanks

No i think it is a vent into the magneto cavity.

It should have a white plastic cap over it. Its where they inject the isoflex grease into the crank bearings.

Its just a vent for the magneto as mentioned. no need to cap it. The one above it with the black hose is the vacuum line for the fuel pump. The 670's were an oil lubed bearing from the injection mixture, not ISOFlex lubed.

Ya they used that vent for the HAC system if it's still installed unless it's a x model which had dpm

What's with the 02 sensor in the pipe? Nice looking motor!

And EGT's. There was some monitoring going on with that engine. Nice!

Thanks, there were a lot of hours in that sled. 02 sensor was for the wideband Air/Fuel gauge. Needed a way to confirm EGT readings because of porting, head and fuel type. Wasn't uncommon to see 1350-1380 on the EGTs with that sled, she'd make good power up there.
