Help - Found something in my oil pan
Pulled the motor out of my C10 and found three pieces of metal that look like teeth in the oil pan. They are a little less than 1/2" long. The disributor gear looks fine. What do you think they are? What problem do I have?

Re: Help - Found something in my oil pan
How long are they? They look like oil pump teeth to me.

Re: Help - Found something in my oil pan
or part of the timing gear oil pump gear is flat on the edges so oil will not slip past

Re: Help - Found something in my oil pan
They look like the teeth off of a timing gear.

Re: Help - Found something in my oil pan
Yep... if they break off the upper gear they will just fall right past the crank and into the pan. If they came off the lower gear they just fall into the pan.

Re: Help - Found something in my oil pan
What would cause them to break off?

Re: Help - Found something in my oil pan
Loose chain on a very worn engine.

Re: Help - Found something in my oil pan
It running well, but leaking like crazy: oil pan and rear main. I was planning on replacing the lower gaskets and I had a previously used Edelbrock intake I was going to put on. Looks like a timing chain and gears are in its future.

Even if it has a stock replacement, I'd be shocked if those teeth could break off like that and the timing set still functioning and not already replaced. Rock the crank back and forth and see how much slop is in the chain. If you cannot confirm the chain and gears are OK to your satisfaction, then pull the cover. Pan was probably leaking because the timing set was probably already replaced when the teeth broke off and the pan was not pulled. It's hard to do the timing set with the pan on and not end up with a leak. Check crank journal where the rear main seal rides. If worn or pitted, you can get an off-set seal to ride on a previously un-used surface of the crank. Make sure it goes back together with a dust cover back there.

^^ nailed it. Inspect the inner lower lip on your timing cover. People often bend that to heck when trying to force the cover on without dropping the pan.

Re: Help - Found something in my oil pan
Yeah while its out you might as well do the rear main seal and possibly oil pump and timing chain. All things tough to get to when in the vehicle.

Re: Help - Found something in my oil pan
I already have the rear main, but will pick up a timing gear / chain today along with an oil pump - thanks for mentioning that, had not thought of replacing it

So go ahead and take the oil pump apart and see if the gears are damaged. Chances are they are not, from what I see. Those gear teeth do not look like part of a nylon timing gear. The pump gears may be scratched up, in that case install a new pump. If not, it's a waste of money and a PITA to install the new pickup tube and expect it to stay on and not fall off later but do take the time to clear the screen and blow it out good. If you do put a new one on, get the pickup positioned where you want it and get it tack welded by a good welder so it don't get a hole burned through it and does not ever come loose or put it in with JB weld just don't use too much so it don't slop over into the system. Only put it on the tube itself, do not put it on the inside of the pump bore. Make sure the pickup tube does not touch the bottom of the pan with NO gaskets installed yet. Best to have 1/4" clearance with no gaskets. (playdough or modeling clay). Or copy the one on it now for angle. Adjust it before the epoxy dries LOL. You will need a new plastic guide sleeve for the oil pump shaft, new pump should come with one. http://www.summitracing.com/parts/slp-224-43343 I'd get the fel-pro 1pc oil pan gasket. Measure your oil pan and note the side of the dipstick to ensure correct application. |

Re: Help - Found something in my oil pan
Look deep inside your oil pump pickup for the nylon pieces that might be there with chunks of timing gear. Never seen one come apart.
