    Default Rat Bastard : Oil leak

    Damn, everything went together just fine, no water leaks,fuel leaks or oil leaks on the trailer. Put her on the water last Thursday and an oil leak shows up. Did some looking around and figure one of the valve covers is leaking enough that there's an oil stream running down the back of the block. Get new gaskets ( those rubber Fel-Pro valve cover gaskets are great) silicone them to the valve covers and good to go.

    Get on the water on Saturday get to the sand bar.......oil in the bilge
    still have plenty in the pan and I have 4 qrts in the boat so we take the kids 9-11 miles up river tubing and wake boarding. As I told Jay ( Warp Speed) not enough of a leak to impede forward progress. Get back and lost 4 qrts. Fill her up Sunday Morning with fuel and oil and take the kids out again to burn avg gas and oil. Felt like the engine was a Jawa 500cc speedway engine ( total loss oil system.... oil just passes thru)

    My new Jon Kaase oil pump puts out 75 lbs cold and 60 hot at idle. Running hot is 65 lbs at 4,000 @ 200*

    Have to pull the damn engine to find leak. What really pisses me off is that I have never had an oil leak from the pan gasket or seal in 20 yrs of engine swapping. And I've had more than my share of swaps. The old Dooley pan never had an issue. Don't know if it's pan related (Stephs kick-out) or something else. Farmer John suggested that I pull it, drain the oil and then seal it up and put a shop vac to the valve cover to find the leak. So tonight I'll scout for the leak. He told me the fast way to fix the leak if I find it with the vacuum. I might give it a try.

    Sunday:



    Monday night:


    So it will get yanked tonight.

    Oh yeah, I forgot to mention that I think retarding the cam 5* to run straight-up really screwed with the idle quality of the engine. That's another thread, but fought that with my old 1050 on Saturday and then my new 1200 Pro-System on Sunday. It's either cam timing or the ignition is doing something real funny Sent an email to Patrick James at Pro-System and he gave me some instructions and Danny Crower gave me a few too. Hopefully I can get the idle closer to where it was. 900 rpm with a lope and 1,100 smooth.

    x2 huntin for oil leaks is old school, dye that sucker and it'll show exactly where it was coming from i use coolant/tranny fluid/ac freon/oil dyes almost everyday on something or nutha.

    Dare to be different, if it turns out great you can claim you planned it that way.

    So put dye in it and spin the pump with a drill for a few minutes ?
    UV dye, do I need a light or will it show up ?

    sleeper why would you retard the cam timing

    i have never agreed with this method to get more power and yes it has always screwed with idle quality and run quality in my cases.

    sorry about the oil leak they can be very frustrating.

    most parts stores sell a uv lite kit with dye jon, they're only bout 20bucks with a uv lite. they make finding oil leaks a breeze. you have to pour the dye in, run the motor just a bit, then look for the leak. mute point if you've already got the motor out , i know, but for future reference anytime i have a oil leak on anything, i pour in some dye, run it, then let it cool off and then i start looking for the dye leak.it'll show up bright orange or green like a blacklite poster

    Retarded from where it was.... the cam was set in at 5* advanced because of piston to valve clearance issues. Straight up is intake opening at 25.5* it was at 30.5* while the heads were off my buddy Randy Walls massaged the pistons enough to get the needed P/V so we set the cam in straight-up vs advanced 5*. Crower (Danny) told me it will run better up stairs. Since it doesn't hit the wall until 6,200 Dan thought it would be good for it and when I trim back my AT HH A to spin 6,500 off the bottle he thought it would love it so while it was apart we made the move. Old setting was max tr of 765 lbs ft at 6,000.

    So don't pour any in and run the oil pump with the drill ? Does it need to heat up to work ? I guess the vacuum will find it.

    Let me guess... he used a grinder of some sort to deepen the valve pockets?

    I wasn't there when it was done

    Out of sight, out of mind

    Edit: Actually the valve pockets needed to be opened up (radical clearance) not deepened. When I do get a new set of pistons to make that thing a 900+hp pump gas engine I need to pay attention to the fact that the heads were milled so much it changed the * of the valves in relation to the standard valve pockets.

    motor has to be ran in the same conditions it'll leak at. the ole vaccuum down the block method works, but it's also hell on valve cover gaskets, but you know that already.

    Dare to be different, if it turns out great you can claim you planned it that way.

    I'm wondering if it's the Cam Plugs on the back of the block? That's where I am leaking and I will pull the motor this winter to fix it.

    I have never had great luck using a vaccum to find oil leaks. But turn it around and blow into the motor all you need is a little liquid soap and water mix (mostly soap, very little water) in a spray bottle, and you'll find right now. Just make sure the vaccum and hose are spotless.

    Hummmmm Yeah I hope I would. If I can't find it with Vac I'll try it this way. Thanks
