I use a couple bolts with washers forged with the heads, like fender bolts are.  They have to be short so they won't contact the main bearing cap.  I install a plastic washer cut  from the side of an oil bottle, put RTV on the threads, and snug them up.

RTV or Permatex is fine as long as the threads are clean and dry upon  reassembly.  If you do not have studs to put back in those two holes, a pair of lock washered bolts with sealer on the threads will do just fine.

They are regular studs.  What Mark referred to was the short unthreaded portion between the fine and course threads.

So I wonder if i can just thread in regular studs w/ a sealer vs. trying to find the right shouldered studs, drop the pan to install, etc?  Cant i just put some sealer on a basic stud and thread it in?  Also, what type of sealer to use?  RTV or ???

The holes in the block are all blind holes.  The ones in the timing cover are drilled through, but they are not within the crankcase.

I might be remembering wrong but aren't other holes along the pan rail open to the crankcase? I thought they might have been used to prevent the retainer from getting stripped.

What Ted said about why the studs are used makes sense to me.The studs actually have a little shoulder that separates the 2 sets of threads.Using sealer and the shoulder would stop oil from travelling down the threads which is what would happen if bolts were used.Ask a question and someone usually has the answer.Thanks Ted.

  

Whoa! I never ealized that! Ill bet that's my problem. What kind of sealer do I need to get?

Thanks!!

I find them to be a BIG help when trying to one hand install the oil pan under the car ! I always go for the studs first then a front bolt.

The oil pan bolt holes in the rear main seal retainer are open to the crankcase and studs with sealer on the threads prevents oil weepage past the threads.  The use of bolts without adequate sealer in these two holes can cause an oil leak that many times is blamed on the rear main seal.
