I don't have ALLDATA any more so I'll assume it's incomplete... It's not the first time. No, you don't use RTV as a HG dressing. It may be required to seal unions if specified. In this case it's placed at the union of the rear, lower timing belt housing the block and the HG.

I don't know why, but there is sufficient pressure there to ensure it will leak sooner or later if the RTV/packing isn't used (ask me how I know).

It's also supposed to be applied here: http://www.cygnusx1.net/Supra/Librar...aspx?S=EM&P=52
