Hi all:

Following the forum's suggestions from this weekend, I tracked down the correct parts & replaced the crush washers at the base of the delivery valves on top of the IP. Out of four, one had no washer at all and the others looked a bit tired.

All looked great ... sent her off this morning ... and it's leaking again tonight . The driver is on the sofa with a "diesel headache" and a glass of wine.

I just took another look and my suspicions that one of the studs on the IP is stripped appears to be true. I noticed the nut felt like it was "slipping" when I checked its tightness yesterday and sure enough it's not tightening down. This is on the same valve that appeared yesterday to be the leak culprit, and it now seems likely that the PO over torqued it a bit and I finished 'er off .


With that in mind, I'm soliciting for [strong] opinions from the experienced here:

1. Aside from the crush washers, is there another likely candidate for leaks coming from the top of the IP? In an example I have from a more recent 5-banger, it appears there's an o-ring on the outside of the delivery valve "piece" (that bolts into the IP, not where the crush washer is). Does my earlier model have this?

2. Is my IP doomed because of the stripped stud or does anyone have a stripped bolt experience ... Perhaps a larger diameter stud or a steel-like epoxy? The latter is likely more easily obtained.


Many thanks in advance.
