Im a dumbass, yes I know. Before anyone says anything About a month ago, the last time I took my UIM off to fix a coolant hose leak, I noticed a large vacuum hose on the back side of the UIM unplugged. I tried to reconnect and cracked it. I took a gamble and just plugged off the nipple and left the hose hanging. Well, come to find out it was the thick hose for the OMP/ line spider thing. How much would this have hurt my car If I only put about 300 miles on it. 1 fuel tank I did run premix, then the other 2 tanks or so was just plain fuel(about half of the driving was with plain fuel. So 150 miles with no internal lube). It runs rich and probably had plenty of fuel coating parts in the engine. I noticed no odd noise or anything acting out of the ordinary (more unordinary than ussual anyway)... think I did anything other than maybe a bit of extra wear on the housings? Not like it matters a whole lot, probably getting a reman engine down the road. Thanks

 

The oil injectors didn't inject any more nor any less oil than if the large line was connected to the spider. That is not a vauum line. It is an air source line of filtered air.

The idle of the engine will be crummy if that line is not connected up.

Someone else can explain the how and why's.

 

Ah, I was under the impression it had something to do with the injecting of the oil. Ok then, never mind

 

It does effect the metering of the oil. IF the line was capped off/plugged off, then the oil injectors will feed and abnormal amount of oil to the rotors.

That line goes to a passage that leads to a hole IN FRONT of the throttle plates, so it's getting that air from a metered source of air via the afm. But if the line is off the spider that feeds the oil injectors, then the air that is gong to the injectors isn't METERED air and it should effect the idle quality if that is the case.

IN other words no harm has been done other than a very small amount of unfiltered air was sucked into the rotors.

 

It took you 3 or more tanks of fuel to drive 300 miles?
