Almost done with truck, Oil cooler leaking!

[94turboidi]

Okay I have been working on the truck as much as I can in my spare time. Today I am thinking I can button everything up and be done. I am putting starter bolts in, intake, batteries, oil....I started adding antifreeze. I put 3 jugs in and 2 gallons water. Then I noticed a small drip. It was coming from the front of the oil cooler. I thought maybe I didn't tighten the bolts enough, nope. It looks like its running out from the top bolt. Well I immediately drained as much antifreeze in a bucket as I could because that crap is expensive. Well I went on with trying to get the truck started. I put fuel in the filter and had some starting fluid. I kept cranking off and on and purging air out of the system. I had to charge it a few times but finally got it started. My glow plugs weren't working but I didn't have a wire hooked up. Well got them working but it still wouldn't start with out either. And when it did it filled up white smoke everywhere and ran rough. I messed with the timing and now it pops right off with the glowplugs. The motorcraft plugs stay on for 10-11 seconds, its awesome. I am starting to get frustrated because I took on so many little things at once.

The oil cooler isn't the one that was on the engine it was on my turbo engine and hasn't been ran in a few years but didn't leak when it was last on. I didn't take it apart just cleaned it up and painted it really good. I have heard something about o-rings, is this my problem? Once I get that fixed I have to bleed the clutch, brakes, top off ps fluid, antifreeze, rear ujoints, put drivers side battery tray in and battery (leaving out in case I need to take fender well out). What stinks is I put every rubber hose on the engine new but the lower radiator hose that came from rockauto was too short and I used my old crappy looking one. I might go ahead and buy one at oreillys since I have t his coolant leak to fix anyways now. Will I need new oil cooler gaskets? Mine are brand new but I am assuming there is going to be antifreeze and oil all over it when I take it off.

I need to get it properly timed when all done I think its still a bit retarded I am going to advance it some more when I get a chance to work on it again.

Do it once, do it right.

I used the felpro oil cooler set when i had the motor out before i installed it in my F350. Also went ahead and replaced the o rings on the tube. I think i paid 5 bucks for the oil cooler set.

I am trying to do it once and right, I just didn't rebuild the oil cooler. I put every gasket, hose, glowplugs, clutch, mounts, clutch hydraulics, ton of other stuff on here new. Had the truck pretty far down. If I would have put on the same cooler I had been using I would probably be fine. I found another post and he mentioned replacing the o-rings, I am thinking thats my problem?

Thats what I found on another post. I probably won't get the gaskets from ford but not sure.

the do it once, do it right was directed at you using your old crappy hose lol

I know the feeling of wanting to get the truck started and hearing it run. I've discovered its much better to take my time, wait and do it the right way so i dont have to go back to do it again.

I don't know the oil cooler oring part numbers, but the last time i got them i got them from the international dealer and i ordered the mounting gaskets from my local parts supplier. I remember the mounting set being felpro. If its running out from where the bolt is, it sounds like its the mounting gasket thats leaking. But if you're gonna go that far, whats two orings.

When I get the new parts and get ready to switch this I am going to take pictures of the ones I just put on. In one corner I believe the silicone that comes on the gasket wasn't on part of it. I just figured it was part of the gasket design. Now that I am thinking about it I think that might be exactly where its leaking. They were fel-pro gaskets, all surfaces were extremely clean and dry. I got the gaskets from rockauto. There are some definite benefits to buying in person. I am not certain but I am thinking these gaskets were a "dud". The lower radiator hose that I bought brand new from rockauto was shorter also, it was a goodyear hose. I took pictures of it next to my old hose and its shorter, it wouldn't reach at all. I am starting to think the reason they have parts so much cheaper on certain things is they get parts really cheap that have been around for a long time or something or blems, etc. I am not saying I won't buy from them again, I did save alot of money getting most of my parts from there and these 2 things are cheap items. I don't have the money right now but I am going to order the orings from ford, possibly even the gaskets, then get a new lower hose from oreillys.

If its leaking from a mounting bolt, it it unlikely to be o rings.

The cooler/block gaskets are metallic with a silicone ring, if I remember correctly. Try snugging up the bolts just in case.

Another thing, if the drip is from a forward bolt, it may be a water pump or hose leak. Stuff in that area likes to run down and drip from the cooler. I ran into that problem.

The gaskets are paper with a sealer print on them. The ford ones anyway. get the orings from ford or IH, the black ones for the oil side that come in the gasket kits will get hard and leak in about 30k miles, I am going to do my cooler today because of that exact reason.

I just did my oil cooler a few months ago. Take your time. also you may need access to a press to get everything back together.

Pickup some assembly lube or something real slippery to put on the orings so they dont slid.

Another thing dont use any type of silicone on the gaskets.

Can the oil cooler be taken off in the truck? whats involved?

 

[94turboidi]

I am planning on removing fender well, exhaust manifold, steering shaft, hydroboost lines. I don't think its the orings but I am going to do them anyways. I am just about positive the gaskets are defective, I will show you what I am talking about when I get it apart.

Removing the exhaust manifold log will give you plenty of room to get the cooler out. Get some 3M weatherstrip cement and glue the gaskets to the cooler manifolds. The yellow stuff is the best. Just a tiny bit on both surfaces.... Let it get tacky and set the gasket in place. Using something on the block side of the gaskets is tricky. If the gasket isn't firmly stuck to the cooler header it can slip from the squeezing effect when its tightened down to the block. These are very thin gaskets without much body to them. Permatex avaition contact cement will work great on the block side....

I didn't know the gasket needed anything additional to seal. I don't think it slipped when installing it was on the stand and I had my wife help out. Do I need to drain the oil or is it all below the pan enough? I figured the filter has to come off ahead of time to have clearance and drain some oil from the cooler. I am slowly working on it but my two boys have other plans today. Probably get it off tomorrow. I was going to order the parts for the cooler online I doubt my local dealer has them in stock.

 

[icanfixall]

If the engine has been test run then yes... the cooler will be full of oil. It can be drained but not all of it will drain out. True... the filter needs to come off so the cooler has enough room to be removed. You might be able to just remove the exhaust manifold and have enough room for removel of the cooler... The menifold will be easy to remove if you had them off when you resealed the engine...

 

[94turboidi]

Yeah the manifold will come off easy. I am gonna try using some shop rags to catch some of the mess. I want to try and keep the engine clean.

Remove the block drain for the coolant and you can save all the coolant in the motor. Figure on draining around 7 gallons. start at the radiator. then the drivers side of the block... the passenger side will not need to be drained. It wont leak across the motor. The cooler has a coolant drain on it also. Its at the rear header....
