UPDATE: It turns out the problem was what I feared; a broken valve on the cylinder head. $7000 later the truck is back on the road.
Ohh, man , sorry to hear that. Did that missing piece of valve damage the piston/ linear ?, perhaps was ejected out. You mentioned on last pages that is D13 motor but doesn't have DPF ?! Did you have both egr and dpf deleted?
Just curious how long after egr delete this happened?? Had a friend dealing with a same situation, that little piece of a valve got sucked in thru the exhaust ports into the exhaust manifold and out thru the turbo, you can probably find it somewhere in dpf or doc filters lol. Start looking closer at your fuel mileage as a lot of deleted trucks won’t show you any fault codes on a cluster and seeing low mpg will mean your VGT stuck.
Not sure why the guy with 1.1 million miles is still having issues. We have changed out process a lot with new installed tools and new sealant etc. The new process is the solution. We went from doing 5 cup jobs a shift to maybe 2-4 a week. We have over 20 techs. To the guy with the white smoke, I know you fixed your truck BUT I would be really worried about the head being pitted. Ive never seen one come in the shop with the same complaint you had and didn't end up with a head. Mostly D11, but we have had D13 with the same issue. Good luck and hopefully you don't need it, though
Ok so if your getting a mechanical fault on a volvo d13 engine for injectors the last thing I would do is change it first you have to check valve height make sure tune up is correct these d13s have idle balancing so when you have a problem with a cylinder it will compensate either minus or positive depending on the problem your having so for example if cyl#6 has a problem cyl#will be compensated to the opposite of 6 please dont let these mechanics fool you into changing parts I've been doing this for 20 years now
Volvo dealership is currently putting 4th set of injectors/cups in my truck since Nov. Its costing them alot of money to keep screwing it up. Cant bring it anywhere else unless I want to shell out another 6 grand. To say the cup/injector issues are taken care of...well that all depends on who is doing them in my opinion.
