#1987 of 4944 Re: rocker arms chrysler 300m [sel] by Mr_Shiftright HOST Sep 06, 2005 (6:08 am)
Replying to: sel (Sep 05, 2005 8:40 pm) Well that's a lot of miles and engines do wear out, but it would be good to know if the rockers arm bushing failed from their own natural wear (cheap materials maybe or not a great design or not frequent enough maintenance?) or if they failed from some type of oil starvation. I suppose the best you could do is repair the damage but not until you assess how good the oil pressure is for the engine in general. It is possible that the rockers failed due to you not being on a severe maintenance schedule, or maybe the engine is full of sludge, and these things have affected oil pressure. It's all hard to say why these things happen, but by all means have the engine's oil pressure checked with a numerical read-out before you repair anything and also have the engine carefully examined for sludge. My point is you don't want to end up just repairing the symptoms and not the disease.

Thanks Mr shiftright. I will ask the dealer to check the oil presure. The oil presure gauge still reads the same as it always has. As for as oil changes the car is driven mostly highway miles 70miles to and from work 6 days a week. I have had the oil changed every 3000mi and few times less than 3000. My chrysler dealer has done every oil change and all maintinence. It has been a good car other than this. Thanks again for you help. Replies to this message: Mr_Shiftright (Sep 06, 2005 6:33 am)

Replying to: sel (Sep 06, 2005 6:30 am) Well sounds like you did all the right things. It's too bad the dealer deflected the original complaint, You were probably right that something was wrong. Next time trust your intuition more and maybe get second opinions. You might even get a second opinion on this problem and the cost of repairs. You could also have a couple of bad valve lifters. Rocker arm failure is a bit odd.
#1990 of 4944 94 GMC Van Power Control Module by rembrandtstl Sep 06, 2005 (12:55 pm)
Having a no start problem. Replaced fuel pump & its wire harness, relay injectors & their wire harness. Engine cranks. But No power detected coming from OBD to injectors. Dealer suggested it was the power control module instead of the OBD and gave us a drawing showing the PCM on the pass. side of the engine inside the van. The Haynes book is of no help either. BUT, we can't identify it! Any help? Or other suggestions as to problem.

#1993 of 4944 Is my fuel pump bad??? by 2me Sep 09, 2005 (6:48 am)
it's a 95 neon 5 speed. A week ago it ran great. it will start and idle perfectly but as soon as you press the gas it "blub, blub, blubs" like a motorcycle with the choke left on. If you let off the gas it goes back to idle. I replaced the fuel pump and it was no better. If you pump the peddle quickly you can achieve the higher RPM's. There is no smoke coming out and the oil is clear and clean. There is the oft mentioned oil in the spark plug tube in one of the cylinders but it looks like it has been there for a while. The head was redone a year ago. Replies to this message: qbrozen (Sep 09, 2005 7:38 am) 2me (Sep 09, 2005 8:36 am) qbrozen (Sep 09, 2005 8:52 am) and 6 more...

Replying to: 2me (Sep 09, 2005 6:48 am) you replaced the pump? What about the fuel filter? Replies to this message: 2me (Sep 09, 2005 8:36 am) qbrozen (Sep 09, 2005 8:52 am) 2me (Sep 09, 2005 9:42 am) and 5 more...

Replying to: 2me (Sep 09, 2005 8:36 am) well, i'm sure someone else will have better info, but i think it could be any numbers of things. bad or clogged injectors or any one of many sensors has failed are just 2 thoughts.
