Dipstick/Oil Pressure Issues

[Foxcroft80]

Hi All,

I'm new to this site, but have referenced it in the past and am hoping someone can help me out...

I have a '68 C10 stepside with a early-mid 70's 350 in it. Earlier this week I went to check the oil and noticed the tip of my dipstick (Mr. Gasket after market) had snapped off. Not knowing where my oil level was at any more I drained all oil, replaced filter and oil in hopes of making a new full mark. When I drove home (about 7 miles) I let the truck sit for awhile before checking my stick only to notice that even MORE of it had broken off and the side had slightly become curled.

Any ideas here?! Obviously I need to get a new dipstick. My oil pressure is running about 3/4 when I'm on the gas and settles in the middle when I'm just idling. Just don't wanna burn my baby up! Any advise re: diagnosis would be greatly appreciated!!

Sounds like the dipstick is hitting the crank. Was there a natural curve to the dipstick or was it pretty straight when it was out of the tube? I would find an original GM dipstick and tube to replace it with.

Your oil pressure is great so you have no worries there....

I know in the older SBC's there is a tube that is down inside the block. This is inside the block were the oil dipstick tube is driven into the block. I know a lot of the guide tubes were left out for many various reasons. But if this is gone it can in theory let the dipstick hit the rotating mass. I agree with LockDoc. Bruce

Go to a gm dealer andbuy a gm dipstick and make sure of the length your puttin in the hole too long it can twist into the crank and get busted off
