Re: [MBZ] loose 300SDL pistons
Assuming the block and head were clean when the gasket was installed (this is necessary, but not always done, eh?), and leak will leave carbon between the gasket and block or head surface. That means any carbon or dirt tracks indicate leaks. The stainless steel ring must contact only clean cast iron or aluminum -- marks between are leaks, as are dark areas on the stainless. Oil between gasket and block/ head is also a sign of a blown gasket. You will also have oily soot in #1. Most common places on a 603 are the end cylinders (#1 and #6) into the chain case in front and into the bolt holes in the rear. This is due to the lack of material beyond the bolts and resultant lower clamping pressure. Second most common is between cylinders, notably #3 and #$ or #4 and #5. This is probably due to higher heat in the middle of the engine causing more gasket crush. Re-using head bolts is also a cause of gasket failure -- if they aren't elastic enough, the gasket will crush when hot, and leak when cold. But the full set, it's cheaper than a new head gasket set to fix it next time in 1 miles. One sign of coolant leaks is excessive glassy carbon buildup on head and piston top. If yours just have loose carbon on them, you don't have any coolant leaks into the combustion chamber. Note that you should clean the head completely, ditto the block, before re-assembly. DO NOT, UNDER ANY CIRCUMSTANCES use Scotchbrite pads -- they shed grit and it will eat the rings in about 1000 miles. Brass brush works great. If you clean the pistons and head completely, you will be greeted, when you get it together and started, by horrible metallic clanking from combustion quench and re- ignition, so if you can get the sealing surfaces clean without cleaning the piston crowns and combustion area on the head, leave them sooty! The noise goes away in a few hundred miles, but is rather un-nerving before that.

Re: [MBZ] loose 300SDL pistons
Usual cause is a blown head gasket oil passage between #1 and the chain case -- enough oil in there, it hydrolocks and bends #1. Not fun, and my brother just escaped this fate recently when an exhaust stud broke and we ended up taking the head off his SDL to fix it -- oil leaking into #1. There has also been some discussion that the sludge in the intake from using dino oil with the EGR connected can cause hydrolock or piston/head interference, too. Nothing like the 3.5L, which dies at low milage in normal use! Peter On Apr 7, 2008, at 8:21 PM, Kaleb C.

Re: [MBZ] loose 300SDL pistons
Kaleb, There is always going to be some "slop" in the piston fit in the bore, even in a new engine. There has got to be room for the piston to expand as it heats up, hence the need for the rings - otherwise you could count on the piston to seal on it's own. The big question is how much slop is there, and how do you measure it? About the only definitive way to do this is to remove a piston, get a set of micrometers and/or calipers and measure both the cylinder bore and piston diameter and compare them to the specs. Also, when you measure the bore, you have to do it in several places throughout to determine if it's tapered, egg-shaped, or otherwise out of round. Based on the fact that the head is cacked, I would assume that the pistons are probably affected as well. Also, by checking the consistency of wear across all cylinders, one would expect the wear or clearances to be identical, or at least, very close to each other. It doesn't sound like this is the case, another reason to suspect the possibility of extreme wear or possible damage. I have no knowledge of this engine in particular, but what I do know from direct experience with both diesel and gas engines I would say you should probably go through this thing unless you're looking for an "Okie rebuild", that is, just slapping a repaired head on the engine and driving off.

Re: [MBZ] loose 300SDL pistons
I don't remember ever being able to wiggle a piston in the bore -- sounds toast to me. Could someone have swapped in a rod-bender engine? By the time you've put the money of a new head on it, and find out it's still toast, you won't be a happy camper. Swap in a new engine. On Sun, Apr 6, 2008 at 5:55 PM, Kaleb C.

[MBZ] loose 300SDL pistons
So I have this 300SDL I picked up a while back. The guy who had it bought it from a list member from another list. Drove it back somewhere in the NE back to OK. Anyway, he says IIRC after a while of driving he couldnt keep oil in it. Not sure where it was going but thats what he said. It broke down and he had ot have it towed back to OK. Took it to a local shop and I know they ran a compression test on it but Im not sure what the numbers where. They pulled the head and I think they said it was warped. They also said the engine needs to be rebuilt because you could move one of the pistons back and forth in its bore. The head is sitting on the engine but not installed. Today I looked at it for a minute and the head does have a couple of cracks between a couple of cylinders valves. #1 piston is at TDC and I can move it back and forth very slightly. I cant tell you how much but its a little loose. #6 is also at TDC or close to it, and I can move it a little but its quite a bit tighter than #1. The others I cant move, they are down in their bore. So the question is, should this piston be able to be moved at all? Given this info and what the PO says happened, would I be better off just yanking the engine and dropping in another? That is what I am leaning towards. -- Kaleb C.
