krede Posted May 5, 2009 Report Share Posted May 5, 2009 I usually discard these as a matter of cause. However the workshop manual says nothing about this.. Are they supposed to be a reusable item?... Quote Link to comment Share on other sites More sharing options...

Pugsley Posted May 5, 2009 Report Share Posted May 5, 2009 I usually discard these as a matter of cause. However the workshop manual says nothing about this.. Are they supposed to be a reusable item?... Unless they're torque to yield bolts, you should. Problems with torque to yield is they stretch back and forth because cast iron and aluminum have different thermal expansion rates. The torque to yield bolts helppick up the slack. Eventually they wear out after being stretched and you get a blown head gasket. Quote Link to comment Share on other sites More sharing options...
V-M Posted May 6, 2009 Report Share Posted May 6, 2009 Those are reusable ones. Have not seen N9T engine with yield bolts. V-M Quote Link to comment Share on other sites More sharing options...
krede Posted May 6, 2009 Author Report Share Posted May 6, 2009 Thanks... its not so much the cost that deters me.. rather than the effort of finding new ones.. By the way V-M... could you supply Piston rings? (maybe bearings as well?).. I've asked Peugeot Denmark if they can fetch me these... but so far no reply.. so I am looking for alternative sources Quote Link to comment Share on other sites More sharing options...
nick@nite Posted May 6, 2009 Report Share Posted May 6, 2009 I got rings Quote Link to comment Share on other sites More sharing options...
V-M Posted May 7, 2009 Report Share Posted May 7, 2009 Deves is good alternative. I have ring sets too... but then you need to use old oil rings. That can be done also with small rework for old ones. Ring set is for 92mm pistons so those ring end cap can be adjusted for worn cylinder. V-M Quote Link to comment Share on other sites More sharing options...
krede Posted May 7, 2009 Author Report Share Posted May 7, 2009 Having seen the state of my oil rings I lean towards the Deves ones... however.. I have had my cylinders Honed.. so my concern is that they might be too small.. (though my pistons are "A" spec.. Quote Link to comment Share on other sites More sharing options...
V-M Posted May 7, 2009 Report Share Posted May 7, 2009 I have good used oilrings ones still also (I can put set of these with out no cost also there). Remember at those deves ones are for good original size cylinder (cant adjust gap size on those). That "A" spec difference to "B" and to"AB" is just thousands of mm so that does not matter on used engine. V-M Quote Link to comment Share on other sites More sharing options...
N9TE Posted May 8, 2009 Report Share Posted May 8, 2009 How yould you know? I thought that TTY bolts were usually torqued down using the "angle method". Isn't that how ours go? That led me to think they WERE TTY bolts. That being said, I've never seen anybody declare them TTY or seek to replace them. Quote Link to comment Share on other sites More sharing options...
Johnny Posted May 10, 2009 Report Share Posted May 10, 2009 No, the workshop manual procedure for putting the head on does not call for the angle-method. Also, torque to yield-bolts have a different design than regular bolts. Quote Link to comment Share on other sites More sharing options...
