Banning vehicles that left the factory meeting pollution specifications at the time they left the factory is what I'm against. If there was a class action lawsuit I think it could win. If the extremists prevail a ban on all fossil fuel vehicles is coming.
The mail man just dropped a set of rings off.
Keystone on the top and second rings. Oil ring also fits as it should.
I'll say this is a win.
I'll hopefully have a complete set for all 8 pistons by the weekend.
I just got off the phone with Rob @ Mahle. He said S42104 is the correct ring for this application. Like I said I have one set on order now Should be here late in the week.
MAHLE / CLEVITE S42140
MAHLE / CLEVITE S42104 I ordered them last night and should ship tomorrow. I got that part number from eBay at the link posted below. If you scroll down to compatibility and click on read more it says that this ring will fit. I guess the proof will be in the pudding...
Upon further investigation, the keystone ring may be the answer.
A drill bit inserted into the groove shows a tapered ring grove.
So where to find the correct rings? I have found this part number (mhlS42104)
I guess this is a Powerstroke piston. I'm not sure what I have going on here. My new rings fit the old pistons, but not the new pistons. I'm not finding a set of rings that spec out to the new pistons ring groves.
I have the turbo rods. I have the pistons mounted on the turbo rods. everything was good there. The top ring grove was too narrow on these new pistons, which is why I ran the part numbers. The valve reliefs seem about the same. In fact, the pistons seem very similar. Maybe these are the correct...
Well, I messed this one up. I was installing my rings on my pistons and no go. The top ring groove on my new pistons is too narrow for the ring to fit. What's up with that? Cross-referencing numbers say the rings are correct. Cross-reference the pistons says the pistons are for a 94 Powerstroke...
I did it. Drilled and tapped. I let my self get in a position where I need this done yesterday. The beater truck I've been using has developed an ominous tap and I'm afraid it might let loose.
Which means I don't want to take the time to fab up new oil feed lines.
