oil leak after gen 3 install

ryanss22 · Aug 20, 2013

I got my truck up and running after several long months of tinkering here and there on it. mods are listed in sig for reference. I had an adrenaline hpop that I sold to a buddy and got his stock 17* hpop that I bought all new O-rings and plug kit for to freshen it up and make sure everything was good, and installed the gen 3 per directions. I stupidly re-used the old mounting gasket and top rubber gasket, well those leaked right at the bottom of the mounting surprise, surprise :doh: well I got all new gaskets from a dealer, torqued the front bolt to 95 ft -lbs per the book and tightened up the rear mounting bolts tight.. I still have an oil leak at the bottom of the stock hpop right by the ipr and mounting bolt, its a slow steady leak. I used a mirror while truck was running to verify where the leak was coming from and am totally stumped how theres still an oil leak with all new gaskets and doing everything per the book.

any idea's on that??

also I have an oil leak that is running down the INSIDE of my bell housing, head is dry with new gaskets and arp's and so is rear oil supply line, can still see the white of the thread sealant via a mirror. I did have a shop replace the rear main seal when they did the oil pan if that could be it or any way of checking that???

sorry for the long post but these 2 oil leaks are the last things keeping me from pulling and driving my truck...

any help would be greatly appreciated

Not sure about the HPOP leak, but the bell housing leak sounds like a rear main. Why did they replace it? Was it leaking? General rule of thumb with a 7.3's rear main is to not mess with it unless its leaking.

nope it was not leaking, its a local big rig shop that does a lot of 7.3 work and 6.0 work they suggested doing it while in there. truck and engine only has 125k miles on it

check the resovoir for cracks next time you pull the pump out. If its sealing right, then either the pump or the resovoir is cracked. If your hpop is leaking in the valley it will more thank likely run out right underneath the turbo onto the bell housing above the starter.

ryanss22 · Aug 20, 2013

the resovoir that the pump sits in that's on the engine block? I had dried up the valley when reinstalling the gaskets to look for new leaks. the hpop had leaked into the first hole only, while the leak inside the bell housing was still a steady leak and when sprayed clean with brake clean and wiped up it still was leaking more then just residual

anything in the valley ends up inside the bellhousing as that is where the drain hole is

Regardless, it's a true enough statement. I've been chasing leaks long enough to ignore them unless performance is compromised.

My hpop leak is bad enough that ot fiills valley in about 15min of idle time. Thats why I really wanna fix this first then run it.

The HPOP gaskets are very easy to nick the rubber during install and leak.

You said shop did oil pan? Id say oil pan is leaking in the bell housing. Mine was and i was careful to try and avoid that happenin.

NyCowboy87 · Aug 21, 2013

Ryan are you absolutely sure the bolts for the hpop are tight? I had a bolt pull the threads out of the cover (they are only in there maybe 1/4") but it felt tight during install and it blew the gasket out within a half hour of run time. I now use longer bolts that thread in further. I wouldnt worry about the bellhousing untill you get your leaks up top fixed. With that much oil leaking it will go all over and could be from the hpop leak.

ryanss22 · Aug 22, 2013

As far as I can tell the 2 10mm bolts in back are tight. Jacob are those the 2bolts ur talking about? The leak is comming from the bottom of the hpop. I stuck a mirror. In the valley to see it. Can I undo everything and. Put sicone all around the rubber ring? Im tired of. Buyimg gaskets lol. On my 3rd set.

ryanss22 · Aug 22, 2013

Could the gen 3 actually put out to much pressure and blow the gasket?

ryanss22 · Aug 22, 2013

Pulld the inspectikn plate and no oil looks like from the pan.

Southmike · Aug 22, 2013

Call swamps.. they have done tons of those and prob know where to look.

ryanss22 · Aug 22, 2013

according to the video my leak is just to left side of the "big hole" where the actual pump goes in.

Yes those are the bolts Im talking about and that's exactly where my gasket blew out. Not saying that's your problem too, just something it could possibly be.
