My D2 is cosmetically nearly perfect....I replaced all the usual suspects that cracked/faded.
Engine runs strong.....no infamous rattle, no 3 amigos lights. All good, until today.
190K miles
Mechanic just called to say it's basically leaking oil from every place it can leak from----valve cover, lower intake gasket, etc, etc, etc.
Please advise what I tell mechanic to do, what is priority to fix first, and so on.
Thx!

 

I would get the engine steam cleaned, and find the leaks more accurately. A VCG leak could be running down, disguising other leaks.

There is actually not that many places it could leak, not that big of a deal really.

 

Did you bring it to the mechanic for leaking oil, or did he discover this while in there for another issue? How much oil do you lose between changes?

 

With so many miles I would be surprised if it didn't leak at those places. When were the valve cover gaskets replaced last time? My valve covers started to leak again after 30k miles. This job is easy/DIY.

 

Perfect, thank you. Another thread suggested putting uv dye in oil after engine clean & tracking leak(s) w/ uv flashlight…do you concur & is there a preferred dye?
BEST part of your reply is that it’s not a big deal, I was sweating it.

 

Yes, saw oil on garage floor and dipstick showed very low / last oil change 2K miles ago.
FYI—I live in Rochester, NY and although this my 2nd disco have been unsuccessful finding a quality indy shop that knows these trucks.

 

Unless the oil leaks are bad, I wouldn’t bother fixing them until you need to tear into it for a bigger job (like Head Gaskets). Coolant leaks are another matter, they need to be fixed sooner than later.

 

I'd check the OEM baffle to make sure it's not the root cause for all the leaks. PCV mod certainly helps!!

 

PCV mod first. steam clean second.careful around electronics. do NOT use a garden hose. then replace any gaskets that need it. check the oil level every few days. Just make sure it's topped off and not getting into the coolant in the meantime.

 

I’m curious about no garden hose, we drive these vehicles through water…
