Well, I am in a bit of a pickle. At least the car is parked in my garage.

Long story short (as short as can be!)- I put a new to me engine in my SD a few months ago. It has worked great. I run M1 5W-40 in it. About a month after I put it in I noticed I was leaving substantial oil puddles on the ground. Looked like it was coming from the turbo drain area. I replaced the grommets when I put the engine in. I assumed one was not properly sealed. I have had to add about 2-3 quarts of oil inbetween the last oil changes.

Last night I park it in the garage and pull the oil pan bolt to let it drain. I come back a few hours later and try to investigate the oil leak. I notice oil pretty much everywhere on the passenger side of the engine. So it was obviously not from the return tube. I realize it is coming from where the valve cover meets the engine. Simple fix right? Wrong. The nuts would not come off and were stripped on 3 of the 4 bolts. I got one off last night by applying counter pressure. I cut the other two off today. I took the valve cover off. Two out of four of the bolts are shredded and have bad threads on them.

How do I go about getting these bolts out? One came loose when I was trying to get the nut off but is still attached.

Also, I have a spare parts engine with good bolts on it.

Is there an easy way to change them out?

Thanks!
Ryan
