OT. Bad heads on Dodge P.U.

LOU from WI · Sep 27, 2011

Gonna let Victor explain the problem with SIL 2000 dodge with 360 CID.He (SIL) has been having problems with the engine missing out. Well Here is Victor with the right information on this truck.The truck has been hooked up to handheld diagnostic tool, No codes show up. This has been going on for over 1 year,that I know of. The fuel injectors have been changed to different port to check out the miss,(also checked with noid light) They are OK. All the sensors, according to him are good,O2-Crank,etc.The head on the passenger side had a crack in it, so he replaced the pass side with a rebuilt one(seems to be a defect from Dodge) The engine will surge really bad for a while, and then clear up but goes right back to surging again.Fuel pressure is good,so he don't think it's a delivery problem. SIL DID New tune up,plugs,wires, cap,rotor button,etc.Even new fuel filter.I've read that it could be a insufficient ground.
Any other suggestions,other than a new engine,which he can't afford.Taking it to the shop is too costly for them to take the hunt and peck system to correct the problem.So much for Dodge,that's why we own GMC.1 exception is our 79 Dodge,but that's simple,carburetor, elect ignition,ballast resistor and it's SIMPLE, to fix.Was wondering if you fellows have (or had) the same problem? Thanking you for any help. Regards LOU& VICTOR. P.S. No wood splitting today, finger is better, Rained all day long.

Lou, are all your vacuum lines connected? If so, you may want to start checking for leaks in the vacuum lines. How I usually do this is to take a can of starter fluid & spray a quick burst around each of the vacuum lines until the engine quickens slightly from the ethier. I would start around the mass air flow sensor & slowly check each line until you hear a quick racing of the engine.

Thanks Bob, we'll pass it along to the SIL, he's a truck driver on the road, so he won't be back till the weekend,but it sounds like something to try to find out. Thank you very much.

LOU

Lou,

Another thing might be worth looking at would be the fuel pressure regulator.

The other half's car (although not a dodge pickup) had a surging issue.. really bad upon startup, but eventually seemed to get better.. Never got a idiot light.. I checked the fuel pressure, but it was within spec at the time.. In hindsight, I should have checked the pressure with the car running and watched to see if it changed while the surging occurred.. But, I was always told to do the check with car not running, but ignition on.

Her dad took it somewhere a couple times and they changed this and that (on advice of one of her friend's husbands), but it still hunted and surged.. Last week, she was backing out of her driveway and it just quit. Took it to a shop.. they changed the regulator, and it's been fine since.. AND NO MORE SURGING..

May not be your problem, but could be.

Thanks Brad,
I will pass this and all other helpful suggestion along to him.Newer vehicles are hard to diagnose,not like the old ones.Seems they have sensors for every aspect on the vehicle,except the ones that tell you "what is wrong".Thanks again.

LOU

You said the truck was missing. Was it missing or surging or both? Some Dodge 360's around that year had head cracking issues between the valves on #7 and #8 cylinders, but those engines set misfire codes and didn't cause surging. When and how the engine surges are important pieces of information. Is it at idle or running down the highway? Hot or cold? Any other driveability issues? Lack of power? Gerard

Is it missing or is it surging?

Don't know of ANY shop that uses a "hunt and peck" method of diagnosing. That’s just plain silly.

A friend had dodge dealer install a rebuilt V-10 in his 2000 Dodge 3/4. It had a similar problem as yours. Had a fuel pump that seemed good, but didn't put out enough pressure. Replaced the fuel pump and problem went away.

Don't laugh but the aftermarket offers new beefier heads than don't crack at a better price.Summit Racing has always treated myself well as a customer.

They aren't that bad if you know what the stuff does. Its mostly pretty reliable. Wires, plugs, connectors, hoses, mechanical parts like fuel pumps and regulators are still the most common troubles.

LOU from WI · Sep 28, 2011

Thanks Buick&Deere,
Will pass it along to him, Seems to be a bad design by Dodge,but no recall on it.Normal I guess nowadays.Thanks again.

Allen,
It's Surging at low and high speeds,Missing at idle.
Just for your info,don't break down around here,cause that is the way the local garages do their job, you bring your truck in for a specific problem, they hunt and peck for week and tell you they can't find it, but you get a really nice parting gift of a huge bill for their trouble.
Regards,Victor

LOU from WI · Sep 28, 2011

Thanks Mark,
I'll have him recheck it with it running to see if that's it.Appreciate the reply.

LOU

Gerard,
His truck is missing and surging,He replaced the passenger side head,with a rebuilt on from O-really,Problem still there.Like I said, no codes with his diag tool.Engine does it both at idle, cold, and warm. Also going down the road it surges,poor mileage.Engine temp,oil pressure runs normal.No loss of coolant.Power isn't there,but that's to do with the surging problem.Timing is on.
Took a pressure test of all the cylinders,they check out within spec, according to him.Thanks for the reply.
Regards,
LOU

Dodge also had a problem with intake gaskets leaking and causing some of those symptoms.

Anonymous-0 · Sep 28, 2011

I had a 2000 dodge 2500 with the 360 that did that to me. It enden up throwing a crank bearing. The dealer told me that the intake gasket was bad on them and they seep. I never once noticed it using antifreeze. Just my experience.

oldtanker · Sep 28, 2011

Lou, I'd have to say that it's one of 3 problems. 1 Vac leak with could be lines or at the manifold but with that he should be getting a code for the MAP sensor. 2, Fuel Pressure Regulator. Will not give a code. 3 Plugged EGR but most of the time at speed symptoms go away and it should give a code.

ASEguy · Sep 28, 2011

First thing I would check is engine vacuum both at idle and then at 2000 rpm when it's warm to see if the catalytic converter is restricted. Stay at 2000 rpm for about a minute. If vacuum drops a little but stays high the converter is probably not the cause. I would then check fuel pressure with a guage taped to the windshield and see if the pressure drops when the problem appears. Fuel pressure is not directly monitored by the PCM. Hoped this helps.

It is common for Dodges of this vintage to have cracked heads. However, cracked heads would not display the symptoms you have described.

Whoever told you to replace the head is out to lunch.

LOU from WI · Sep 28, 2011

Hillybillyjack, no-one said( even in my original post) that we replaced the head for the fact of a cracked head would cause these symptoms.It was cracked... There was no compression on that valve,causing the engine to push unburnt fuel out the exhaust.Now that it is fixed,compression is where it's supposed to be, but have a bad miss and stumble at both warm and cold engine- stumble at speeds.Just trying to figure out why it is and maybe someone here has had the same problem.Thank you.

Victor

LOU from WI · Sep 28, 2011

Thanks Rick,
Your suggestions are really appreciated,I'll have him try them,maybe he can get the truck fixed.Nothing he done so far made any difference,so any ideas that come from here will be passed along.
Warmest regards,
LOU

LOU from WI · Sep 28, 2011

Dodgeit,
Thanks, if I'm not mistaken,I think he replaced those a few years ago, when a TSB came out,but I'll have him double check it. Appreciate the suggestion.
Regards,
LOU

LOU from WI · Sep 28, 2011

ASEguy,
Thanks again,
All suggestions are helpful,I'll have him try it.I've printed all the helpful ideas out so he can go thru them and try them out.When he finds out what it is,I'm sure he'll be happy.Has to have it running right before something else major would break,costing more money than he can afford now.Again thanks.
Regards,
LOU & VICTOR
