Thread: Torque Plate, piston clearance, etc.

    Torque Plate, piston clearance, etc.

    I'm rebuilding a 6 bolt motor for my '93 AWD Talon, and I was hoping someone in the Denver area might have a torque plate I could use/rent to bore and hone my block.

    Also, any advise on piston clearances and cylinder wall finish would be helpful. I bought some forged, coated pistons (Venolia), stock comp. ratio. I believe they are zero silicon pistons, like JEs, so I know they will expand, and may (will?) slap a little when cold, but I got them for $300 w/rings. They are moly rings, file to fit, Venolia gaurantees less than 2% leakdown, but I know they need to be broken in right. I'm trying quick seat dry assembly lube to help the ring break-in, anyone have experience with this stuff?

    Also, I got some Eagle rods, and noticed the oiler holes on the big end are missing. Did anyone use Eagles and remember if the oil hole was there? This seems like a critical detail to me...

    Thanks, I totally appreciate any help anyone can offer, hopefully my car will be back on the road real soon.

    I used the Total Seal quick seat stuff on my 2.3, and it works.

    There are no oiler holes on the big ends.

    oiler holes

    I double checked, and on my 6-bolt, stock "big rods", I did find oil holes on the big ends of the rods. They are chamfered holes in the bearing surfaces directly facing the small ends, with small diameter bores pointed at acute angles up towards the small ends. The other side of the holes are very small, almost like a pinhole.

    I'm not sure what they are for, but my Eagle rods don't have them.

    Thanks for the torque plate, Jake.

    Well, since the bearing doesn't normally spin in the rod , I don't know what those could be for.

    Maybe cooling?

    None of my eagles or crowers have them.
