hi again i have done my gasket and i beleive gonna have to redo it but before i have noticed a small leakage of coolant underneath the water pump there seems to be a little hole wich i guess would be a sort of overflow or something. my problem could this be due to my base gasket wich dont give it the pressure needed to not leak or is it a usual thing or not i havent noticed it before all i know could be the gasket or at worst the pump seal is anyone familiar with this have got some good feed back from this forum and beleive can happen again thank you in advance it is a 91 lt 250r the motor is between 91 and 93 but supposively they stoped in 92 wich could be this one in this case

 

The little hole is there to let you know when your water pump seal is leaking. You have to remove the pump and put new seals on both sides of the impeller.

 

i imagine it could have done this cause i have less oil in my base i chequed and looks to be low not sure is the oil supposed to go right to the filler hole cause theres no dip stick on it and dont want to overfill as well is the 900 ml the amount of oil i have to put in it well thanks again for replying and if you know will help me also which oil should i use for the motor base
thanks again

 

There's no oil in engine. The oil is for the transmission. I use Bel Ray 80w-90 gear oil for a wet clutch system. 900 ml is the amount to put in. It won 't come to the top of the fill hole. If the oil looks milky your water pump seal is leaking and the oil level will get to high and come out the overflow line.
