Safe To Drive.....? My '28 has a.....decent rear main leak. I would like to attend the Model A Days in the Amanas next month, but I doubt I'll have enough time to address this. It's going to be anywhere from 80 - 100 miles one way. Would it be foolish to attempt this? When I bought the car I drove it 65 miles with the leak and no issues. Not that that was a smart move.

Re: Safe To Drive.....? I definitely would not...But I admire those who throw caution to the wind.

Re: Safe To Drive.....? I wouldn’t do it.

Re: Safe To Drive.....? ...even with the occasional pit stop?

Re: Safe To Drive.....? How much is it leaking? Stop and check the oil level every 10 or 15 miles until you know how often to add some and drive your car. You bought it to enjoy, so enjoy it.
You might put some oil absorbent pads in a pan to shove under the car when you stop so you don't make a mess. Maybe slide them inside a garbage bag so you don't get it in your car. Go have fun. |
Re: Safe To Drive.....? Are you going by yourself or with a group? No one likes to tour with someone who has to stop all the time. If you are going by yourself I would bring plenty of oil and have a backup plan to get home.

Re: Safe To Drive.....? A decent oil leak? How much oil did it use in your 65 mi run? Some engines leak oil at the full level, I run mine at halfway. Some people use a rear main janitor that catches the oil. With the oil level at halfway I would try running 30 mi out and then back and check the level, 50 mi out and then back and check the oil level. Again with the oil level at F it may leak and somewhere less than F it may not be so bad. One last thing are you put the oil level ( dip stick) in with both parts of the stick? If your put it all the way in you may be over filling the oil?

Re: Safe To Drive.....? How much.....? Well I can follow myself out of the driveway at times! The puddle under the car is about a foot across.

Re: Safe To Drive.....? anyone who was driving a model A in the 40s probably was leaving a bit behind. mine leaks a bunch if it has 5 quarts in it. leaks a lot less at 4.5 quarts
i keep a gallon of oil and water in the back. |
Re: Safe To Drive.....? That's a big puddle...What type of oil are you using? Sometimes as the rear main bearing wares...and the engine loosens up...you should/can move from 10-30 or some such to just 30wt and the dribble will slow down...long term, you need to drop the pan and measure the clearance at the rear main as well as the other two...you might need a general tightening up...also many A's will toss out the first one half quart and then settle down and not toss out much more at all...Ours has this habit.

I'd be by myself. No one in my area to go with. |

I haven't gotten around to estimating yet. The last guy said he just ran it 2 quarts low all the time and it was fine. Where would that mark be on the dipstick? Yes, I do put the dipstick completely in. |

I can't remember what I'm using now. I'd have to check. |

That is a good way to look at it. |
Re: Safe To Drive.....? If you are intent on going to that event, trailer it, save your engine. If you don't have
a trailer, borrow or rent one. |
Re: Safe To Drive.....? It may be a combination of the rear main and the oil pan gasket. If it's all from the rear main then it's not like you can change out a seal since there is nothing but a slinger there. It may need the bottom end babbitt redone and the crank turned if it is still in decent condition. It sounds like the former owner wasn't too worried about it but that is usually the case when folks don't want to rebuild the bottom end. Folks tend to run the old model A engines till they're knocking but sometimes that's too late to repair things. It gets more expensive when more things are worn out.
