Doing my buildup and installed my type r oil pump a few days ago.
I just finished up and installed the stock (B16A) bottom plastic timing belt cover and it does not fully cover the timing belt on the bottom. If you notice in the attached pics I have the stock B16A oil pump on the right and the new oil pump installed on the block. The stock oil pump has extended edge that meets the plastic cover to fully encase the timing belt/gear at the bottom. On the type r pump, this edge is too far out and a different shape - does not match up, so there is some open space around the edges (see pic).

Question is.. Do I need to purchase a lower plastic timing belt cover from a type r? And still use my B16A top one - will it even work? I know the B18 block is taller, maybe the bolts won't even match up? Do I even need it to completely cover it?

Thanks

 

Simply modify the cover you have now using a grinder

 

I don't need to remove any material from it - it fits fine.. It would be great if I could add material to it - I am worried because the crank, lower timing belt gear, timing belt are all exposed to sand, dirt, water, etc on the bottom, left and right sides.

 

Get and obd2 b16 lower timing cover. Obd2 is larger due to the use of the crank sensor on the oil pump.

 

any obd2 b-series cover will fit perfectly or do as MTBER told you (slight mod with dremel tool).

 

I need to swing by and check it out when its done.Pm me if you need any help.

 

get a 99-00 civic si cover. the gsr and itr covers are a bit taller and wont fit properly if youre using the upper timing covers

 

Thanks everyone, picking up a 00' Si one tomorrow...
