Huge problem with a 95 Dodge Ram 1500

That sucking sound could be a vacuum leak. See if you find out where it's coming from. A large vacuum hose goes to the brake booster.

Where did the oil go? Did you burn it? was it getting sucked into your vacuum leak and get burned? is there a bunch of oil drops where you park? Really need to use foamy engine brite and a hose to find the leaks~

momo probably needs an intake gasket~

Could there be engine damage in the form of being hydro-locked with oil, bending valves and blowin' out rings?...let's hope not~

The engine never overheated, temp remained steady throughout the week. Oil pressure dropped bad during last day before my check came in. Filled it up and did good for a few days, filled up the gas and the problems started two days later, usually stays under 1/4 of a tank 99.9% of the time. Could it be a clogged cat? I'm lost on this one.

You still runnin' okay? gettin' blue smoke? idles evenly?

clogged cat would throw up a CEL~

It idles good, shakes a little when you go to accelerate and evens out until you hit 45-55mph, then the shaking kicks in. It shakes so bad that it can get hard to keep straight on the road, but as soon as you hit 60+ it evens out with a skipping kind of sound and feel, but no bad vibes.

"shaking" frightens me. all I can think of is hydro-locking with oil what's leaking into the combustion chambers...not quite certain how this might happen short of cracks all along the belly of the oil jacket...course it could be a coolant leak...would have to keep an eye on the exhaust to see if it's blue or white~.....still this "shakes a little" makes me wonder why? too much something in the cylinders...but what now~?

mysteries abound~

is the check engine light on? if so what codes are on the obd?
