Radiator Stop-leak for Gasket Question

Last winter I had a complete engine overhaul on my MF203 done, Perkins A3.152. Now that it is back together and the loader is on I noticed a small coolant leak coming from where the front plate meets the engine block, directly beneath the injector pump. It is leaking only when the tractor is running, maybe a drip every 5 seconds. The last thing I want to do is remove the loader and get back into this engine. Do you think a radiator stop-leak would seal this up? The tractor is not used much, maybe 10-20 hours a year. But when I do use it, it is for about 3 to 4 hours at a time.

Any suggestions?
 
I thought I had the same Coolant leak..however there was a CASTING /FROST PLUG leaking from behind the FUEL pump. Casting plug is a TIN insert that was corroded.

Have also seen TO LONG of CAP SCREWS used to assemble the Coolant pump, as well as the front adaptor plate, thus the GASKETS were not sandwiched tightly.

I never answered your question....personally, I would check to see if all Cap screws are of correct length and verify the integrity of the CASTING PLUG behind the fuel pump.
