Technical Does your hot rod or custom have any leaks?

Discussion in 'The Hokey Ass Message Board' started by HOTRODPRIMER, Oct 7, 2019.

  1. Over the years I have been plagued with a leak or two with my hot rods, sometimes hard to locate where it's coming from other times it's obvious.

    A small transmission fluid leak can leave a huge puddle under the car and a generally easy fix, often it's just a mater of tightening a bolt or replace a gasket.

    Most of my oil leaks can be traced to my valve covers, how do you guys make your engines leak proof, or can that possibly be done? HRP

    surprisingly, my 33 is the only vehicle I have that doesn't leak! I'm sure it'll be leaking when I'm done with it though, hah

    my 46 Willys I used to park it over a large (4'x3'?) concrete mixing tray. Engine, transmission, transfer case, and front diff always leaked. haha

    My avatar car, has a bad transmission leak, but I plan on replacing both the engine and transmission with larger units, so I just let it leak now and put a pan under it. Seems like I don’t sweat the small stuff as much... anymore.

    My Chevy II has not been leaking at all for a couple years now. It's spooky!

    but my old pickup truck leaks, so all is not lost.

    I have spent a fair amount of time trying to get my cars to not leak. Never been completely successful! If it's not leaking, it's probably out of oil...

  7. Flatheads leak, period! That front seal does anything but seal.

    Both my rides don’t have valve covers yet still manage to leak some oil. Mark nailed it.

    I'm on gasket set 3 to try to stem the flow from the front oil pan with my SBC 327.

    The original 239 y block in my wagon leaked every type of fluid, transmission, power steering, oil, coolant and the carb seeped.

    The new 292 has no leaks sofar :) I’m super picky about installing gaskets and will spend a lot of time with a hammer and dolly straightening flanges.
    The car still has a power steering leak but only in the winter. Each spring I add a bottle of Lucas power steering stop leak and it won’t leak all summer. Over the winter the seals dry up and it leaks on the floor of my friends garage where I store her.

    The windows all leak but I try not to drive it in the rain.

    leaking is not the car's fault... It is the oil trying to find its way back home.....

    Might be that the gasket isn't the problem...try replacing the timing cover and/or oil pan. If either of them are aftermarket chrome, especially...see if you can find good old OEM original old parts.

    I concur. Much like a Harley, it's simply marking its territory.

    Back when I working...... my OT daily driver had a huge leak, that kept my frame from rusting! Lol
    I parked in the same spot every day. Between the oil, carbon, dirt and whatever, I was getting a fairly big thick spot. Being a public garage, I got a lot of salesmen coming through trying to sell me everything in the book! If it was a chemical salesman with cleaners....... I would send him out to THAT spot! Told him if his product cleaned that spot , I would buy.....never bought a thing! But it sure sent them on their way! I kinda liked that spot! I’ve been retired 7 years now, and it’s almost gone.

  24. Mark, you ain't right! :D HRP
  25. Did you put oil in it?:confused:
  26. Actually only one leaks there.:rolleyes:

  29. Chicks roadster leaks a bunch because we like the look of a fined oil pan,,, the fined oil pan come from across the pacific ocean, where they make all thing metric,, so the pan seal sucks,,, but it looks cool.
    So the drip-pan under the motor had almost more oil than the motor,,,
    But we have a new clean-up solution,,,
    For those of you that have kids or aged parents, a absorbent bed pad under the motor grabs the oil and after a while, a proper disposal takes care of the once oil soaked floor

    I had a friend with an MG, leaked a quart of oil per week and the underneath was always soaked in oil, somehow the floors still rotted out.
