Found this in my oil pan - what is it?

I found some chunks of metal in my oil pan and inside the oil pump inlet spout. Anybody know what this might be from? I will be doing a full overhaul but so far I can't tell where it might be from.

OK, I think I know what it is. It is probably the end of the camshaft with the slot in it. I guess the previous owner snapped it off and it dropped into an oil passage and they never bother to pull the oil pan to get it out. The camshaft must have been replaced (or the entire head?) because the cam is intact and the head seems to be in very good condition.

definitely the end of the cam, another reason not to torque the cam gear bolt with the holder tool..
You'll wanna do a new cam at your next TB interval..

I thought the cam lock tool was used to allow torquing the cam pulley bolt. How do you torque that bolt without using the locker tool?

That's a cam sprocket holder. use it to torque the cam, pump or int shaft bolt.
So the pins on the metalnerd product go into the cam sprocket holes??? The thing then rests against what to stop cam movement? Can this be used in conjunction with the cam locker to maintain proper orientation of the cam so that timing remains correct?

How do you stop the cam rotating while you tighten the bolt, since it has no keyway?

Wrap some lead flashing, (sheet lead), about a cam lobe, this protects the running surface, adjustable spanner upon the cam lobe, jobs a bogey!
Why on earth is the torque setting for the cam bolt less on the diesel than on the petrol? Anyone? :?

Here's my cam locker tool:
This is the pulley side view. The smallest hole goes over the injection pump pulley locker (Tool 2064), the one next to it provides clearance for that pulley's bolt and the large hole clears the washer integral with the cam pulley bolt. The bolt head on the tool (that's a 5/8" bolt) fits into one of the large openings in the cam pulley. It's about 3mm smaller that the size of one of those openings, so the pulley moves about a tooth's distance before it locks up and allows loosening the bolt. I assure its remaining in place with a couple large spring clamps.
This worked just fine for loosening the bolt, and I expect it'll work for tightening once the bolt is snugged up a bit.
However, now that the bolt is loose, how do I get the pulley off? It's on the camshaft tight, and there's no room for even my smallest three-arm puller. Will the injection pump puller (Tool 3032) work? I didn't have time to try it yet.

Use a hammer and hit it from directly above. Only hit the timing belt though. Of course, if you do this you absolutly MUST replace the t-belt. You don't want to hit it really hard, and it usually takes a fair bit of tapping to get it to come off. Keep the large bolt threaded into the end of the cam to prevent the pulley from falling and breaking

The belt is off the pulley and I wish to reinstall the belt--it was replaced about 40K kms ago. I've slugged the pulley repeatedly with a large rubber hammer, one of those that pack a pretty good whallop, and it hasn't budged. I've determined that the injection pump pulley puller won't fit behind the webbing of the camshaft pulley, so I can't use that. There is very little clearence between the pulley openings and the timing belt rear cover. Do I just keep pounding?

Yep, just keep tap, tap, tapping away for a few beers, and just as you are about to give up for the day,.........crick.......and off it pops! :twisted:
Or if you have them, a couple of hardwood wedges work too.
Gently is the name of the game here......! :wink:

I'll post this here too for reference:
There is a small hole (5mm) in the metal belt cover towards the front of the cam cover, which lines up with the back of the pulley. Put a punch through here and tap it with a hammer. The pulley should come straight off.
