Well thanks for all the info I have gained off this website. Bought a 2003 F350 crew cab about six weeks ago. Installed the 6637 filter, CCV mod and inserts for the plenuims from Riffraff Diesel. Bought the oring kit from Guzzle as I had a leak on the topside of the engine. Replaced the turbo orings and all was good, for about a few hours. Next day, made a run to Mrytle Beach (330 mile round trip) Made a stop in Jax and Camp Lejuene to check the area out. Came back to the truck, had good size oil spot under the truck. Checked the top of the engine, dry as a bone. Heading south to Mrytle Beach and then back home. Checked oil upon returning that night, went through 5 qts for that trip. The entire under carraiage was coated which makes a nice rust preventative BTW. Rechecked everything the next day, to include pulling the turbo/pedestal in case I did not get it seated right. All was good there, still dry as a bone. Put UV dye into the oil when topping off, started truck and crawled underneath. Leaking from oil pan area and rear main seal area. Took the truck to one shop, they steam cleaned the engine to find the leak. They determined oil pan area and then would not work on it, too large of a truck for them.
Went to a diesel repair shop on Hwy 70 in New Bern, just got the call, oil pan leak starting and possible rear main seal.

Riffraff and Guzzle, you guys make great products.

 

dang that sucks, seams like a lot (5qt) for a "oil pan leak starting and possible rear main seal" in 330 miles.The motor will need to come out for both. I would be dang sure that was it before I let them tear in to it.

Is this a possible rusted out oil pan?

and welcome to FTE

 

theres 2-o-rings under the pedestal as well?

A member posted up a you-tube link, that showed a company selling/installing an oil-pan cover, that essentially cured the leak.

 

1) Am I only the only one picking up sarcasm here?? I'm hoping this is unintended.

2) CCV mods in general are retarded IMO, that oil isn't hurting anything.

that being said, try putting the CCV back to stock and see if the leak clears up, I know a few guys on here have been lucky like that.

 

No sarcasm really. The products are great and I have highly recommned them to the Marines that work for me. I did change out the lower and upper orings for the turbo/pedestal. Bottom ones were shot, thats why the top of the engine was wet, now its all dry and staying dry. Top orings did not need to be replaced, but to be on the safe side they were replaced. I did the CCV mod just because I wanted to mess with the engine some. At the rate is is leaking, I do not see the CCV going back to stock is going to decrease my oil use at all, but it is an idea if needed in the future. Had the mod done for about a week before the onslaught of oil leaking out of the oil pan area. It just happened everything wanted to fail after fixing the minor leak.

I have seen the video, however, at this time will just have the pan replaced. I would do the work myself here on base, but have only been back in the states for 6 weeks, before that two yrs overseas (MCAS Futenma, Japan), seeing my wife and kids about every 5-6 months for a couple of weeks at a time, plus I have a newborn. Its at the point more about spending time with the family, letting someone else fix the truck once they determine everything that is needed and I get back my family time and a truck that will not be leaking. One kid was 7 months when I left, saw him grow up on Skype, other one is 6 weeks now, and a 9 yr old.

Semper Fi

 

I don't think so. What would Guzzle's o-rings have to do with his oil leak at the pan? The only way to pressure up CCV would be if he kinked the hose.

Good luck with the fix.

 

Welcome to FTE and THANKS for your service. Take care of the family and spend some long needed time with them.

 

just IMO, but if it were me and I developed an oil leak right after a ccv mod, i'd put that **** back to stock faster than Obama prints $$. Seriously, it only takes a second to unhook it, and hook up the stock stuff. You don't even have to remove the can from the truck right away, just get the stock stuff back on there and see what happens.

 

Welcome to FTE....Thanks sooooo much for what you have done for this country...We appreciate you and your fella Marines.
Hope you can spend time with the family now.

 

have you checked the epv (exhaust back pressure) arm that comes out of the pedistal??? If i am correct, that can appear to be the rear seal, at least that is how mine looked......

x2 and 3 here.....Thank-you for your time

I think its EBPV....sorry, not very up on the termagoly (or spelling)

 

Checked the EPV, its dry, the whole engine vally is dry after I cleaned the area out and replaced the orings for the pedestal/turbo.
The bottom part of the engine is wet, along with my entire under carriage.

 

I'd have to say rear main, or rusted oil pan. I wouldn't think a rear main could leak that bad, though... I could be wrong.

 

I too would question the CCV mod for this leak after just installing it, but so many people have done this mod with no problems. I for one have not and will not do the CCV mod. I run my truck in my shop all the time and I don't want the stink while working on my truck.

 

I do, but I don't wanna do the mod... I have 295K and blowby is minimal, but still obvious. I wouldn't want my truck to be at a stop light with smoke coming out under the cab... it looks like I have a problem! On top of that, my truck does sit and idle alot and it'll be even more when I get my air compressor installed... as for the smell, I don't know how bad it is. The only reason I want to do it is because I've degreased my motor once and I really don't wanna do it again.

A doubt the CCV would be the problem if he's got a new 6637... the only way it could be would be if his hose is kinked.

To the OP: how far do you have your hose running... under the cab, to the fuel tank, out the bumper?

 

CCV hose has a 6 foot section, ends around the drivers door area. There is no kink in the hose at all. Been checked multiple times by mutliple. There is no low point for anything to accumalte. I do see the blowby coming out of the hose, most people thing there is something wrong. Unit was installed according to the instructions off RiffRaff Diesel. Orings for the turbo/pedestal installed as per the instructions from Guzzles website.

Again the engine valley is very dry and very clean.

The leak did not start immediately after the mod, but rather about a week later for this fast leak. Going through a quart of oil every 60-70 miles gets expensive real quick but it did give me a rust preventative for the undercarriage, one last thing that was on the list of things to do.
