OMG! Threads of cranshaft bolt wet with fuel/oil.


Recommended Posts

Pulled the timing covers to double check timing on a 2000 OBW trying to diagnose a misfire code and raw fuel on plugs 1&3 (see previous post).

 

When I pulled the crankshaft bolt out it was wet with something that smells of gas and oil. Wiped the bolt dry and inserted it again, ohh... it's wet alright!

 

No signs of wet anywhere else around the crankshaft or gear. Car just turned 111k miles; strong runner up until now.

 

I'm panicking at this point...

The crankshaft pulley bolt was wet with fuel? That is a bit odd. It may have oil on it, since the service manual says to oil the threads before installing it. If you reinstalled that bolt make sure you tightened it enough, if that baby loosens up you are in trouble.

 

If you have oil in the spark plug tubes that could cause the misfire. Also if those cylinders aren't firing sometimes you are dumping raw fuel into the exhaust and maybe some of it is getting into the oil especially if you make a lot of short trips.

I'm going to go ahead and assume it was oil from when I did the timing belt. I can't remember but the manual does say to oil the threads, maybe I did that and the oil just hasn't gone away.
