Trouble after replacing valve cover gasket
2006 BMW 325i N52 Engine
1. NGK (1208) ILZFR6D11 Laser Iridium Spark Plugs
2. MAHLE VS50533 valve cover gasket
3. Victor Reinz Valve Cover Screw Set
Replaced spark plugs
Replaced valve cover gasket
The car started to idle roughly and hesitate while driving. Eventually I got a misfire in two cylinders.
When I went to replace the spark plugs I noticed cyl 1/3 had oil in the cylinder well. So, I changed the
valve cover gasket. However, I forgot to tighten the 3 middle 10mm bolts (22 bolts total) that held on the valve cover.
All bolts are 10Nm + 90deg
I tried to start the car before I realized the the bolts were loose. It would not crank. NOOOO!
After tightening the 3 bolts I left loose, I tried to crank again. No luck
I checked the spark plug cylinder wells and the valve cover to oil leaks - there was none.
I pulled out the spark plugs, and every one of them had what looked like oil/black residue on the electrodes, not the threads.
I cleaned all of them off, and tried to crank again - no luck
I pulled out the spark plugs again, and all of them had the same oil/black residue on them?
I'm assuming the problem cranking the car has to do with the spark plug electrodes having oil/residue on them - at least
that's my first guess.
Any help would be awesome!
Es esta una buena pregunta?
