Hello I couldn't find any info searching and i don't have a oem ITR service manual, I have a B18C-5 Crate motor from the dealer and the motor is reaching about 60,000 miles and i wanted to know when its recommended to change the oil pump, i believe the water and timing belt should be changed at about 50,000 miles so if anyone can let me know that would be great thanks. Im about to boost the motor and i want to service the engine before i put on the centrifugal super charger.

 

no need, can take it off and inspect it(in service book) but good well over 100k

 

So at about 100k it should be replaced? Was i correct about 50k on the water and timing belt?

 

Timing belt is 90k miles or 84 months, water pump is just recommended @ the same time because everything's apart anyways.

 

you're good on the oil pump, unless there's an actual problem with it, but that's almost unheard of

 

There's no schedule on the oil pump. T belt and water pump schedule is 105k miles/7yrs IIRC. There's lots of 200-300k mile B18's and other engines with factory oil pumps.

 

I have 233K on my R, and never had issues with my oil pump

 

Thanks guys! i just want to keep up on the maintenance on this C-5 motor! i have allot invested and want to be on top of everything! so i will just change the belt water and oil pump at about 100k.
