Dipstick problem?
I think either my rods or crank hit my dipstick and took a little piece of my dipsick off. I have a dart block and gm dipstick that is correct but i have no idea what happened. Should i be worried about the little bit of the metal from the dipstick or will i be ok? I say a 1/4 inch was tooken off . Has this happen to anyone else. Thanks

Re: Dipstick problem?
First we never run a drip stick in a race car. If it leaks fix the leak. Oil come and goes to quickly to worry about oil level.
Second it a piece of metal hit another piece of metal to shear it off and fling it around the crankcase I'd at least pull the pan. Or check though the inspection port.

Re: Dipstick problem?
try taking the drain plug out and using a small magnet on a stick (you know the retractable ones) and fish around in the bottom of the pan and try to get it out.
Re: Dipstick problem?
What would I need to plug the dipstick hole is there a certain size plug I could use or just put silicon over the hole. I am not running anymore dipsticks there is no need too after this incidence. Thanks for the help.
Re: Dipstick problem?
I would clean it real good and fill it with Permatex Ulter Gray sealant. It's been said to drive a steel pin in the hole and seal it but I'm one that like's to keep my options open. The ultra gray gets hard enough to do the job but can be removed later if need be.

Re: Dipstick problem?
I tap them and put a pipe plug in them. But that's for when you have the apart. The silicone idea will work until you have the engine back apart.
I think the pan needs to come off if the magnet idea doesn't work.

Re: Dipstick problem?
Ultra Grey works great. As long as there is a crankcase vent system. But I would pull off the pan, and inspect everything! Even check all the bearings! Good time to inspect and measure ALL the clearances. And take your oil pan, and set it up level. Fill it with measured solvent amounts to see HOW MUCH solvent it does take to top it off just below the windage tray. Our 8 Qt. Milodon dragster pan only held 6 qts. Plus 3/4 qt. for the System 1 oil filter. ( We have always ran 50w Race + 15 oz. STP) With .0025-.003" bearing clearance. Wet sump Milodon pump/pickup. @ 65 lbs. @ idle. 130 in the traps @ 8650 rpm.

Why so much oil pressure?

Re: Dipstick problem?
Was wondering the same thing. You only need about 60-65 psi pf pressure at rpm. Especially if your n/a.505r10 wrote:Dave Yonemura wrote: ( We have always ran 50w Race + 15 oz. STP) With .0025-.003" bearing clearance. Wet sump Milodon pump/pickup. @ 65 lbs. @ idle. 130 in the traps @ 8650 rpm.

Re: Dipstick problem?
i have a bunch of old wheel bearings that i took apart and then i use the rollers and tap one of them in to the block and then i put a little ultra grey silicone on top. i would be afraid of just using the silicone if yoru using a vacuum pump you might suck it in

Re: Dipstick problem?
Your crank runs on an oil film, not on a dry bearing. One of the Top Fuel motors we build and tune runs 200 lbs. + @ 10,600. Check out on http://www.nitrosheriff.com

Sorry, I didn't realize your other post was about a top fuel motor, which I admit I don't know anything about.

Re: Dipstick problem?
I've been around some of the fuel scene also. It's been a while but not much has changed as far as the bottom end goes I'm sure. You're right,...those guys do run a ton of oil pressure. They are also not n/a. Their cylinders tend to run a tad more pressure.
Now back to the n/a world,...yes the crank runs on a film of oil. But it doesn't need over 60-65 psi in an engine that isn't running any power adders. An engine only needs so much oil pressure to maintain that film of oil. Pro-stock engines aren't running the kinds of oil pressures you're running. Why?...cause it's eating up tq/hp to turn the oil pump. Anything over the required pressure is just a sponge for power.

Re: Dipstick problem?
Back in '66, I had a '65 Impala, 283, that did the dipstick thing. It broke right across the full line. Lost about 3/4" off the end of the stick. It stayed there for many moons. I couldn't see how it could get through the pickup screen so I left it. When I finally did pull the pan for some reason I don't remember (it wasn't to get that piece), it was laying there on the bottom. No problem.
