Engine oil leak....help!

[pro11]

97 f-250 psd has a slight engine oil leak on the rear. Is this a major problem or what needs to be done? How much would it cost? The truck has 140,000

that page was helpfull. but i noticed it was for 99-03. will the pictures on that page look the same for my 95?

[MacDougall]

mine is doing the same thing about 1 drip a day, does it look like its dripping from the passenger side of the engine from that rear bolt? (sorry if that made no since, but if it is leaking from there you will know what im talking about)

[Marty]

95 has same block and mostly the same setup. Yes, that page works for you too.

Guys... check on top - not the bottom. Most of the time the leak seeps down the back of the block all over the bellhousing and makes it look like your leak is on bottom when it's really now.

Remember - follow the leak forward and UP until it stops... then look all around. It will usually move down and backwards

My leak is coming from the rear main....now what?

[pipelayerjdh]

It may look like a rear main, but it is most likely a HPOP fitting or turbo o-ring. I learned this the hard way. Before I found this site, we had a '94.5 that was dripping oil out of the bellhousing. After replacing the rear main twice and new oil pan it still leaked. We tried dropping the pan and re sealing it countless times. I just never knew to look on top of the engine. It will be hard to see, but it is probably coming from the top. there is a drain hole in the valley that lets the oil run down to the rear of the engine.

I have a 97 F250, my problem was the oil plugs & o-rings on the plug in the head, Ford has revised the plug and oil rings to solve the problem, cheaper if bought at International

I know that many keep their trucks clean enough to notice this and that, even with the years listed it might not be relative. But I thought I'd post it as a friend of mine sent it to me and my brother's just found his Ranger oil pan rusting through(and he keeps it very clean, but is also in Ohio on salted roads).
At anyrate, just an FYI as a thought to check yours next time you're under it as some have been found to rust through to the point of leaking...
