603.971 broken windage tray
I removed the windage tray and oil pump as a unit from a 603.971. As I put away bits and pieces for the night, I found on the garage floor a 1cm by 2cm shard of the windage tray separate from the tray. I loosened the bolts then spun them off by hand. The tray came of cleanly and easily though I might not have noticed the shard already separated. I fished out of the oil pump screen some bits of o-ring, RTV and a couple of metal shards. I can't tell if the shards came from the windage tray. I haven't gone deeper into the pump.
There was a member who was against these windage trays and insisted that anyone fool enough to reinstall one should use thread locking compound. IIRC the bolts go on dry at the factory. But now I wonder if there is merit to that sentiment. What causes a windage tray to disintegrate? The engine has been apart before so maybe the tray was damaged then. The bolts are evenly spaced and in plain sight. It's not likely someone missed a bolt and yanked the tray. There would at least be indications that it got bent and was reshaped. This tray is straight. Sixto 87 300D |

I'd love to see pictures of this.

To come. My paws were too oily to handle a camera.

A windage tray on a diesel? You learn something new every day... I'm surprised the crank spins fast enough to make it worthwhile.

For some reason the .97x engines have them, even though they have a lower redline then the 3L engines.

Yeah, I'm against these in the 3.5L's. Yet another pain point with them. Never saw their true purpose.

What are you going to do then?

Could an impact on the oil pan have done that?

If there is no evidence of it being hit or the tray being removed by forcing it out or the tray doesn't sit flat and caused a strain on the area. Then I would guess the cause to perhaps simple metal fatigue from engine vibrations. .

windage tray bolts
I noticed low oil pressure at idle on the 350SDL. End result was 2 windage tray bolts loosened and fell out. The crankshaft picked them up and took out 2 piston spray jets along with a small thumbnail shaped piece of the piston skirt on the 2 cylinders.
I made the decision to put it back together with new jets, oil pump, and thread locked the windage tray bolts. It runs hard daily with no issues. I would check the bolts as a precautionary measure so you do not have major issues. |

I suppose I can weld the broken off bit back on the windage tray. I'll clean the windage tray and check the other attachment points.
Impact in what way? Like a connecting rod bearing came off at high rpm? I haven't discounted doing something wrong as I removed the windage tray. I loosened by hand all the bolts which were similarly tight then lifted the windage tray and oil pump as a unit and set it on the floor. It wasn't until I lifted the deal from the floor that I noticed a piece remained on the floor. Sixto 87 300D |

No i mean like running over something, hitting the bottom of the oil pan.

Ah, the oil pan looks good but it might not be the original oil pan. As viewed from below, the windage tray attachments are recessed (higher) where they attach to the main caps. Something that hits the windage tray would do a number on the louvered sumps adjacent to the attachment points, or so I'd expect. This section of the tray sits above the crossmember aft of the oil pump. Maybe a mount failed and sent the engine crashing onto the crossmember?
