Well, my '94 Ram 1500, 360 magnum, 213,000 miles, 4x4 has an ignition miss, is steaming out the exhaust and actually has anti-freeze dripping out of tailpipe. Do you think it's a blown head gasket or cracked head or what else would cause this? Also, milkshake oil.

If the engine never overheated, it should only be the head gasket. But you can't rule out the head. I would say it will be a 90% chance it will be the gasket. I've seen head gaskets blowing anti-freeze out back. Good luck.

When my small block did that, it was a cracked cylinder wall. Those cylinders are thin.

Personally, at 213,000 miles, a motor miss, steaming and antifreeze out of the exhaust, and milkshake oil, I'd say it is time for a motor. Nothing short of a major repair is going to fix it now. Sorry. Gene

Quite possible its a head gasket? Was it ever overheated? if so much more likely to be gasket....By no means does it mean you need an engine. At least not till you're sure what the problem is...


Take care,

Sure will need a rebuild though. Water in the lower end and run enough for anti freeze out the tail pipes means new bearings for a start.

a couple of questions first. how rusty is it, what else is wrong mechanically, and how much do you want to spend ? if it isn't rusty, and still mechanically sound, either a re-man or junkyard motor. if it is rusty and/or has other issues, may be best to think about a new rig. just my opinion, your mileage may vary.

Is that one of them with the eng buried inside? If so from your descrip I would pull the eng. If you do have easy access I would pull the heads but I'm sure (as said) it will need to be completely opened up. When the time comes holler how it turns out.

Just because you have milkshake oil doesn't mean you need new bearings.....I've fixed many engines w milkshake oil and never replaced bearings and they never came back w noisy bearings.

Absolutely agree with this because a headgasket can fail many different ways. If it's only seeping coolant into the combustion chamber. The bearings are in no danger.

This may not answer your question directly Stumpy340 but a 94 with over 200,000miles. Basic math on an average 25 year old truck. It might be more cost effective to move on to another truck or as Moparx said, just swap in another motor.

Since these motors usually outlast the trucks you can probably find a good replacement for a few hundred.

As much as you guys like to dispute everything, nearly everyone reached the same conclusion I stated very early.

A 94 Ram has the motor buried way back under the dash. Ever just changing head gaskets is a pita on them. Its faster and easier to pull the motor to change the heads/gaskets then it is to fight with them while still in the truck. Add milkshake oil and 213,000, and changing the motor for a lower miles motor in better shape just makes sense (if the truck is worthy of a motor), and may be cheaper then heads and gaskets. Gene

Anti freeze and bearings don't get along well. They are to cheap to not change after being contaminated. If you have gotten away without replacing them you have been real darn lucky.

The other possibility is that its just the intake manifold leaking coolant into the oil, and you might be able to reseal it and change the oil a couple of times.

I don't believe that's the case anymore not that it's a good idea to run antifreeze in your oil.

I remember in the late 70's 8v92 Detroit Diesel engines had an issue with liner seals. They would fail rather suddenly and if the low coolant light came on and you didn't shut it down immediately, the crank went flat very shortly after. Glycol would destroy the bearings.

Sometime shortly after that they either changed the formulation of the antifreeze or the bearing material or maybe both as glycol contamination just doesn't seem to be an issue anymore at least in the short term.

I seem to recall 3.8 GM v6's with plastic intakes that leaked antifreeze and all they did was fix the leak and send it down the road.

i bought my brother an oldsmobile at the auction with one of those engines. i don't remember how many miles it had, but he put a ton on it after purchase. he was in florida when the intake took a dump. he changed it out in the parking lot of a building that was under construction. i remember him saying the one crew was pretty bit$hy with him asking to borrow a few tools for the fix. biggrin
anyway, after the fix, he was stationed around the country and canada, finely arriving in california. after the intake fix, and several super close oil changes, the car had over 200k on it when he sold it.
the real problems with that car started after he sold it in california, and kept getting registered letters his car had been impounded. but that's a story for anouther time .....

Probably because new cars don't come with babbit bearings anymore, but aluminum. Antifreeze eats babbit


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

very good point on the bearing material. anyone around here old enough to have had the pleasure of re-babbiting rod and main bearings ? it is a [sorta] fun job ! biggrin

Yep, that's antifreeze coming out of your tailpipe.

As has been discussed here, it could be several different things. But the only way to know for sure the cause is to pull the valve covers and heads and find out.

I would definitely stop running it that way, though. you aren't doing the engine any favors, and it isn't going to fix itself.
