Back in the 70's they had twist in metal caps. My '75 Vette has them.
Do you have much blow by??? Those caps really shouldn't blow out. A friend of mine had too much and screw in caps...it would blow his dipstick out about 2" and puke oil out the tube

Would be a good idea to check blow-by as stated earlier. I've got the push-ins on my 461s and they've never pushed out. The problem with too much blow by on marine engines is since the dipstick tube runs all the way to the bottom of the oil pan (so you can suck out the oil with a pump during oil changes) if blow-by is enough to push the dipstick out, it's going to puke oil out of the motor also. Be careful...

thanks guys, the blowby isnt really the issue, I have a hard enough time just getting theese things to stay in place without the engines running, add to it a little heat, and a hard offshore pounding and thats all it takes for theese things to pop out

Both of my mid 80s GM trucks have the clip on style...
I would think someone still makes these ????
I may have a set of chrome.......I will check....

Bite the bullet and buy the good push in oil caps from GM. The rubber aftermarket junk caps become hard after a short time and fall out easily (as you have found out!). The rubber GM built caps stay soft and last forever. Take it from an ex- GM partsman.
