Car Forum / Dodge / Dodge Cars / November 2004Engine Question, 3.3, crossed to a.a.toyota
Because there are some sharp techs in .toyota (right, tegger,mdt?) Anyway, here's the deal: 1992 Plymouth Grand Voyager, 3.3 litre, AWD, all power, etc. Great body, AWD works, really good shape, 122,000 miles. Now, the problem. Makes a very loud ticking sound from the top of the cylinder bank nearest the firewall. If you listen to Car Talk, you know the sound (Click and Clack, but VERY loud). Guy says he's been driving it for 12,000 miles this way. Engine runs strong. My mechanic won't work on Chryslers, says this can be involved. Has anyone had this problem, can tell me what it is, and what I'm looking at to fix it. Other than this, the van is Very Good. Hopefully, it won't break the bank to fix it. Alternately: For Sale, 1992 Plymouth Gran Voyager, 122,000 miles good shape needs engine work, $800.... Well, it sounds like a bad lifter or the oil galley is stopped up and is getting ready to break the rocker arm mount, common problem with this engine if the oil changes are neglected Glenn beasley Chrysler Tech > Because there are some sharp techs in .toyota (right, tegger,mdt?) > [quoted text clipped - 10 lines] > Alternately: For Sale, 1992 Plymouth Gran Voyager, 122,000 miles good > shape needs engine work, $800.... > Well, it sounds like a bad lifter or the oil galley is stopped up and is > getting ready to break the rocker arm mount, common problem with this engine > if the oil changes are neglected First guess was a bad lifter. Nobody I know wants to have a look!(One tech just laffed at me, chuckling "Chrysler" as he did!) Is there a quick fix? Like I said the guy I got it from said it's been doing it for 12,000 miles! > Glenn beasley > Chrysler Tech [quoted text clipped - 12 lines] >> Alternately: For Sale, 1992 Plymouth Gran Voyager, 122,000 miles good >> shape needs engine work, $800.... Agree with maxpower. Valve lifter problem here. Ever had the valve covers off? How much sludge? It should be pretty easy to isolate the noise to one of the valve covers with a stethoscope. Pull it off and check it out. Don't know specifically this engine, but some engines carry oil to the valve train through tubular lines. If you have hydraulic lifters (a favorite of American manufacturers), similar problems. Sludge either of those up and your valve train is starved for oil. Only a matter of time then before something breaks. And you don't wanna know what that would cost to fix... --TeGGeR? > Well, it sounds like a bad lifter or the oil galley is stopped up and > is getting ready to break the rocker arm mount, common problem with [quoted text clipped - 13 lines] >> at to fix it.

[quoted text clipped - 10 lines] > > --TeGGeR® Oh, I don't need a stethoscope, you can hear it loud and clear; cylinder bank closest to the firewall, to the right of center. Ok, I'll ask you: any way to fix it easily, or at least hold of major damage for a few thousand miles? I'm only going to be driving it about 7,000 a year, would like to get a couple years out of it (although the body is SOLID! and it doesn't have the usual Chrysler tranny problems...) Of course, it's the cylinder bank that you have to remove the intake plenum for, it couldn't be the front... >> Well, it sounds like a bad lifter or the oil galley is stopped up and >> is getting ready to break the rocker arm mount, common problem with [quoted text clipped - 13 lines] >>> at to fix it.

Ok, > I'll ask you: any way to fix it easily, or at least hold of major > damage for a few thousand miles? Probably not. If the oil feed is impaired, your valve train will wreck itself in short order. Keep an eye on the oil. If is starts to show silvery streaks, major damage has already occurred. > I'm only going to be driving it about > 7,000 a year, would like to get a couple years out of it Won't get that if the valve train is starved of oil. > body is SOLID! and it doesn't have the usual Chrysler tranny > problems...) > > Of course, it's the cylinder bank that you have to remove the intake > plenum for, it couldn't be the front... Pull the front cover. If there's sludge in that, there's sludge in the other. Is this a pushrod or OHC motor? If it's OHC, it's possible there is an oil feed rail that can be unbolted and cleaned out. Again, I don't know if this engine has hydraulic lifters or not.  SignatureTeGGeR?

He'll find out. When somebody asks me, is it the good one or the bad one, it's *always* the bad one! Of course it's pushrod (hmmmm..interesting...I've been told the engine has a timing belt...) and that they are notorius for having bad rockers. Maybe I'll luck out and it'll just be a rocker going bad...but I doubt it. I called a guy I know who's a Chrysler guy, he has two of them I was scavaging parts off for the last one I had (gave it back to the guy who gave it to me, he decided he needed it after all...229,000 and ran like a watch :( ) The only 3.3 he had was flood damaged and seized, otherwise "...I'd just give it to you..." > Because there are some sharp techs in .toyota (right, tegger,mdt?) > [quoted text clipped - 7 lines] > it is, and what I'm looking at to fix it.

See: http://www.allpar.com/mopar/33.html Go toward the bottom of the page, "Rocker arms / rocker arm pedestal breakage." Fixing mine using the shortcut method described cost about $300 but that was on an LH car with excellent access, and included inspection of the other head for cracking in the same place, fortunately didn't find any; and replacing both banks' valve cover gaskets, which were leaking anyway. Doing it on the rear bank of a minivan could be awkward. -GP >> Because there are some sharp techs in .toyota (right, tegger,mdt?) >> [quoted text clipped - 26 lines] > > -GP Wow. I had actually found that page on my own but missed the relevance of the fix described. Thanks! |
