was looking under the truck today there was s very light coolant film on the oil filter and a drop of coolant on this ground cable at the front of the engine under the oil cooler. It was rebuilt w Ford parts 4 years 50k Miles’s ago. It is leaking at an extremely slow rate but wanted to see if anyone has had a similar issue////hoping its not something crazy that’s causing the leak.
Just over here trying to get my 2 front shocks, injector o rings billet plenums, diff and trans fluid swap, trans cooler, oil change, weird vibration solved to get to the starting line and now this.

Attached is the photo looking up from the front drivers side

Finally got to start round one of cleaning and what I found was RTV was used to seal the front housing of the oil cooler to the engine (from when I paid to have an oil cooler rebuild done) yet another reason I now refuse to pay others to work on this truck. About a 4 inch piece pulled off from the upper quadrant of the housing. I have a pretty new water pump and hoses I’m confident it is not leaking from there.

Does anyone know know if I can buy just the gasket? I really don’t want to spend 100 on a kit when I’m at 30k on the rebuild.

I feel comfortable they did the best they could and maybe something happened like the gasket was accidnetly not picked up. Still needs some more cleaning but it doesn’t even look the gasket was installed. The shop that did it only works on powerstrokes. Years ago the owner asked why I was bringing him my truck when I could work on it my self. That was the last time I brought it in lol. Still he has a lot of spare parts so I still see him every now and then.

Last time this happened was on my outboard at a local large marina they used a ton of gasket maker on the o ring for the mixing chamber when replacing the 800$ fuel pump....2 hrs of run time Later the engine was acting like a fuel pump was broken again. I saw the problem brought it back to the dealer and they told me the problem was water in the fuel I needed to give them 900 more and there is never a problem using RTV there. Of course zero water in the fuel I redid the job cleaned the glue covered screen and she’s been running strong since.

Thanks to everyone as always and Brian42 for the parts look up

Ohh I’m going to ask him alright after the repair; when it’s face to face negoiting the price on one of those parts. LoL

Oil cooler job went well save your self and drop the driver wheel well cover. The mechanic did use the gasket yet also used so much RTV it lost seal. Several thousand miles in no more leaks....coolant that is lol
