1981 6cyl
When i bought my inline 6, 250 the owner said he rebuilt it. stock rebuild nothing fancy, well when he yakned the oil pan, he said there was no gasket, some silicone and that was it, well he said, it never leaked oil till the rebuild which he put on a oil pan gasket that came with the kit.. which now leaks in front of block and rear..
I cannot go a mile down the road or let it sit for 15 minutes without being a whole quart and a half low, i let it sit for a few days and theres barely oil reading on the stick.. well the owner said he went to napa and got another oil pan gasket and nothing changed.. I'm getting lost.. Any help? |

Re: 1981 6cyl
Is it a one piece gasket, or like a four piece? I'm not really familiar with those motors. If it is a four piece, was silicone used where the pieces meet?
Maybe your oil pan is not perfectly flat? Rear main? Timing cover? Maybe some pictures could help if possible. -Jeremy |

Re: 1981 6cyl
I had that problem with the gasket on my 305. Upon looking at it closely, I found that the pan gasket fit wrong. It had a bulge for the dipstick on one side, and my block had it on both. It used a quart of oil every few minutes like that.
I am not at all familiar with that engine, but the troubleshooting methods should still apply. Try to find out where the oil is coming from. Clean up everything really well with a rag and brake cleaner, and see if it leaks while idling. If not, run it up the street and back, and see what gets oily. Keep driving further and further round trip, crawling under it each time, until you get it to leak a little. Then you can identify the problem. Slonaker |

Re: 1981 6cyl
i got a I6 in my truck, it had a leak so i pulled of the oil pan and there was no gasket (stock motor no rebuild) i put on in and it leaked so i took it out and just used silicone (or gasket maker) no more leaks
just an idea it worked for me |

Re: 1981 6cyl
let it sit for a minute, then put the pan on, tighten half way, let it semi dry and then torque it

Re: 1981 6cyl
do you have a haynes manual
if not you do not have to fully remove the motor loosen the motor mounts and tranny mount, put a jack under the front of the oil pan (with a piece of wood between the pan and jack) and lift her up abit, the undo the main bolt of the motor mount and remove it ,once you have the inner motor mounts above the outer, reinstall the bolt, now the oil pan will slide out, with some wiggling (installation oposite of removal) hope this helped |
