Problem with sleeved B18C6 running on GT3076
Gents,
I'm from Germany and currently facing second time the same issues. Maybe u have got an idea where to search for: Specs: B18c6 with sleeves 82mm Wieso low comp pistons Eagle rods ARP rod / head studs Garrett GT3076 turbo Car is doing almost 420 hp and runs pretty strong. After 4k km the first engine started to smoke blue and consume oil. First inspection showed a pressure drop in cylinder 3 cause of wear in the sleeve. Engine was rebuilt and got oversize pistons and was bored / honed In Addition a new Honda oil pump and new oil squirters were installed 2k km after the rebuilt the same issue occurred again. There is massive wear on one of the piston making the p2w clearance pretty wide. Nothing fancy happened, even the Videoband did not recognize anything strange. What would u search for in the first step? Video can be found on this link: Link |

Cylinder wall problem, rebuild, same problem again.. Static variable here: crankshaft. Check main and rod journals for #3 I bet something is out of round causing the piston to beat the shit out of that cylinder

interesting point with the crankshaft, crank was only polished in machine shop, maybe sth is wrong on the crankshaft |

not if it was just a polish. Did your p2w cleanse match with piston manf. Spec or similar? You never named the manf. Of the piston
I will remove the crank and rod to get them checked in a mashine shop |

Those are wiseco pistons, so the p2w clearance is within their spec
