I thought there was something in the front... inside the timing chain area. Damned my freaky memory.


There are three oil galley plugs behind the timing chain. The two outer ones have a small pinhole in them to help supply oil to the waterpump gear drive. This was an update according to some service manuals. My '92 had them.


YES! That's it!


The book "How to rebuild small block Chevy LT1/LT4 Engines" says about these plugs with the hole in the front; "these are an oddball size you may be forced to reuse them. Coat them with locking compound then apply a two part epoxy to assure a good seal" I just reused mine.

I was wondering about head bolts, can I reuse them, is that wise or should I get new ones?

As for the oil galley plugged by that ball in the back, I told the machinist to remove it and then clean the motor and then reinstall. Hopefully he did.

I checked the mains with plastiguage and have 2 - 2 1/2 thou. on all. Still have to check the rod clearance.
