well i have been to lucky to long. last night my car quit firing. to make a long story short, i lost 3 teeth on the dist gear. the ones that are there are sharp as a knife. lunati (sp) roller cam, msd dist. i bought the dist used and it was supposed to have a steel gear on it. now i wonder if it wasnt a regular cast gear. i could just put another gear on and run it or i could completely dissassemble the engine and clean it out. i think the answer is somewhere between these two options. what do you guys think?? thanks------------------

That happened to me once and I just cleaned the oil pan out. if you can't get the oil pan out without yanking the motor maybe you could flush it? I've never done that but have heard of it being done with good results.

You have been puting very small metal particles in the oil while your cam has been eating the gear. I would completely dis-assemble the motor and check all the bearings.John

You'll at least need to look down the distributer hole and see if the cam gear messed up. If it is, there's no need to install a new gear on the distributer yet...Of course it would be 'best' to tear the whole engine apart and check the bearings, but at the least, the cam gear needs checked. If the cam gear is in good shape, and you had the wrong distributer gear, the proper one will probably to the trick. If you DID have the correct distributer gear, the distributer will probably need shimmed to get the correct contact patch on the gears... as that relationship was probably screwed up somehow. Good Luck! ------------------

thanks guys, mike the teeth that are left on the gear are worn out in a very even pattern all the way across the gear if that helps. thanks------------------

Mike, I think mine was a different deal, I just had a couple of teeth break off. I found all the pieces in the oil pan, the oil looked clean. You could cut the filter in two, maybe take a peek at what was going through the motor. ?

If you don't have a magnetic drain plug then get one.
Cut open your oil fileter and see what it looks like. If it doesn't have too much metal in it then do the following.
FLush the motor out with some kerosene or laquer thinner and 4 quarts of cheap oil and a cheap filter.------------------

I don't know if it's the best or not Jerry, but it's what I do.
If I hurt something (besides a crank) at the track and I'm 300 or more miles from home this is what I do in the field.
First off, we don't put an engine together without a magnetic drain plug.
We will cut open the oil filter to see just how much stuff actually made it through the system. 9 times out of 10 the filter does it's job.
We drain the oil, then use a lot of brake clean in the cylinder head valleys, lifter valley (if the intake was removed). 2,3,4 cans if needed. We'll put the drain plug back in and pour in a quart or two of kerosene, or 5 minute motor flush. Then we'll try to slosh the motor around by shaking the car and jacking it up.
Drain again and inspect.
Pour in 4 quarts of cheap oil and another quart of kerosene used with a new filter.
Fire it up and let it idle for about 3-4 minutes.
Drain again hot and cut open the filter again.
If the filter looks good, then refil with good oil and new filter and go race.
We've done it 100 times with our stuff and mostly other friends or customers cars.
Obviously, if we suspect the problem to be bearing or crank related, we will pull the pan and inspect them first.
We would only do this for broken cam, valve, spring, pushrod, head gasket etc. issues. ------------------

Anyone seen the deal where you use 4 cobalt magnets around the outside of the oil filter to trap ferrous metals?This is popular around aircraft piston engines, but never seen it on a car before. Greg

I have a fairly strong magnet about the size of a silver dollar on the bottom end of my oil filter as well as two nickel-sized strong magnets on my oil pan drain plug head. They are strong enough so they never move from their location until I go to change my oil; then I remove them and drain the oil. I put them on all my vehicles. If the magnets are fairly strong, the magnets will hold the particles right thru the pan and filter body. When it's time to change your oil, pull the magnets off and the particles should flow out with the oil. If you can't locate any such magnets, I've seen a couple of places that do sell oil pan plugs with a magnet inset in the end. I've also seen a collar type affair that goes on the outside of your oil filter to also function as a trap. -- Maybe JC Whitney or local parts store??? Ryan
