Timing Cover Leak - 3 Bolts Missing (AC Compressor Removed)
All,
I just picked up a nice 1985 4Runner DLX that has been cosmetically restored. One of the issues was an oil leak near the oil pan, timing cover area. The previous owner removed the AC compressor but I noticed those 3 bolts that attached the compressor to the block through the timing chain cover were never replaced. The bottom two is where the leak is occurring. I have no plans to put the AC compressor back on right now, so I went ahead and ordered a new bolt set from LCE.
I'm hoping to at least hack my way through this to get me through the summer (not a DD) and at least slow the leak. Anybody think I can simply get those 3 bolts back in there torqued properly and stop the leak? I was planning on using some RTV also around the area.
The reason I ask is, I'm planning on doing a 3.4 swap in Fall of 2019, so I don't want to spend the time and money replacing the timing chain if I don't have to. I don't have access to a garage as I live in the city and will most likely be paying someone to do the timing chain if I have to, but mechanics I've called are quoting astronomical numbers (> $2500).

Putting rtv silicone over a leak is a lot like trying to put a bandaid on in a swimming pool, it needs to be dry and clean and in the right spot or its not going to work.
Depending on the quality of the gasket putting the bolts back in with appropriate sized washers might seal it back up. But that seems to read as the leak isn't from the loose area and you need to reseal the oil pan.
