I've got a OBD 1 GSR motor and recently i realised i have an oil leak around the oil pan, the VTEC doesnt engage any more and if i do try to accelerate the car is sluggish and the here is white smoke out the exhaust.

yes yes i know i got a ton of problems . i am about to rebuilt the motor, new rings , bearings, new gaskets and seals. I realise that i everone is also saying that the oil light could mean oil pump on the way out as well, so i am going to buy one from my supplier, however he is selling Topline Type-R pumps. i would like to know if they are any good? or shoud i definately get a OEM 96-00 TypeR pump?

And can the long oil light when starting when cold be the pump for sure or can it be the oil leak and bad rings?
