Hi, below are some pictures of my B16A2 civic engine which as you can see on the pictures has been picking up on the piston/bores for some reason. This is the second time this has happened, the first time it was blamed on a missing oilway plug in the head after its original build, but this time after a rebuild there is no obvious reason.
The engine has covered around 400 competitive miles gaining three class wins with no problems, oil pressure is great and still is, got hot once on the start of the North West Stages, went into safe mode for one mile but didn't boil or lose any coolant, in fact the standard gauge didnt go into the red, the capillary one said 115 degrees
Brief spec is standard block/crank/oil pump, steel rods, JE forged pistons, 11.5 cr, ACL bearings, ported/modified head, vtec removed, toda cams, jenvy throttle bodies with cold air feed and pipercross 600 airbox and filter, omex 500 ecu, mapped on rolling road, tony law manifold and 18 row mocal oil cooler, using Valvoline racing 20/50 mineral oil.
It's been great but at Weeton a few weeks ago it started to blow blue smoke from the exhaust on the start of the later stages, was fine on the stages and still managed 7th OA, but it was obvious a problem was brewing.
All four pistons/bores are the same, with wear on both thrust faces
Thoughts anyone ?
