Hi all!

New to the forum.. I just had given to me a lovely 1998 concorde with the 2.7l in it.. of course it was free because the engine is knocking . It actually did pretty well apparently because it has 199000km (120000 miles) on it.

Anyway, I pulled the oil pan out and sure enough it has a spun connecting rod bearing. I'm sure if I replace this it'll run for a while yet and since it was free and I have little expectations of this being a reliable vehicle I figured I may as well replace the bearings and run her for a while.

My question is, having never done this type of repair before, how do I go about determining the size I need? I see there's something about oversize rods when I go to order stuff at rockauto. Should I just buy some std rod bearings and put them in?

Also, wondering if you guys have seen this:

I made one out of 1/8" plate using a plasma cutter and some grinding.. since the PO had the valve cover off it was already exposed. At least now I don't have to worry about the timing chain tensioner failing!

Thanks!

 

bad news... once a bearing spins, you MUST replace the rod. The 2.7 has a powder metal rod. it cannot be resized. and if you spun a bearing, you MUST have the crankshaft ground or replaced.

Trust me, I've done more 2.7's than I care to remember there's no short cut that will work.

There's several 'fix kits' out there for the crappy engine design.

One of these days, I'm determined to put a 3.3 in place of a 2.7 POS
