Big End Caps

Recommended Posts

If some idiot kicked them over and mixed up their order before I could attach them back to the rods would this be a problem? I'm rebuilding the engine and, obviously, new bearings will be used.

Yes it would be a major problem as each cap and rod is a matched pair. However if you fit each cap in turn to each rod and examine the honing marks very carefully under a good light you'll be able to see which cap has the matching marks to which rod. It's a distinctive pattern like fingerprints and always allows rod caps or main bearing caps or cam bearing caps to be identified to their correct place of origin.

if its any help they will have markings on one end of the cap as well, which will help in putting them on the right way, shame they arent marked like the mains!

My mate did this to his.

It's pretty obvious by just running your finger over the join, there shouldn't be a step between the cap and rod.

If your unlucky to get a pair that are too hard to tell by feel use pumas method.

Mine had different coloured blobs of paint on, which I presume was done by the factory. Lesson here is always clean & mark things like this as you take them off. As you've discovered, sod's & 205 GTi law will operate otherwise!

The exterior of the castings are fairly roughly machined before the cap is separated, so you might find matching those up easier than matching honing marks.
