    Oil Pressure
    « on: February 11, 2002 - 09:35:29 PM »
    I know oil pressure is very important but exactly how important is good oil pressure. I did my oil pump this weekend, replaced the old  one, when i removed the old throat to screen piece that goes to the bottom of the pan, it was filled with crap, i mean loaded up with gasket material,pieces of plastic i dont where came from, i couldnt of been using 1/4 capacity of the screen it was that bad! but the car ran fine with no problems even though the screen was full of debris :-/ so my question is how much effect does oil pressure have ?

    Oil pressure is important, it is definatly not uncommon to find all kinds of junk in the pick up, at least it was doing it`s job & not letting all the garbage through!! :o If you are not revving the engine very high it won`t make a lot of difference but it only takes a split second with no oil & things will get hurt fast. the rule of thumb is 10 psi / 1000 rpm + you need adequate pan capacity & volume which is why high volume pumps are available ;)
    Maybe thats why you heard the ticking ???

    Usually there are the remains of the hardened valve seals that end up in there ;)

    The plastic pieces could also be from one of those POS plastic tooth timing gears too!

    Yeah, but a previous owner could have replaced the chain & gears when they went bad and not bothered to clean out the pan.

    This brings to mind when I bought a wrecked RamCharger. The guy said it was rolled, which visibly it was. No big deal cause I wanted the 400 engine for my newer RamCharger. He said the engine was newly rebuilt.  8)

    I pulled the engine and took the intake, valve covers, water pump, timing cover and oil pan off to check out the condition. Everthing sure enough looked brand new!  :P
    I just swapped the single roller timing chain for a double roller, painted the engine Hemi Orange, stuck some chrome valve covers on it, put everything back together and installed it in my truck.  ;D

    Well, that engine never, ever ran properly. It always used a lot of fuel, ran terribly hot, with different carbs, still couldn't tune it right and it kept melting the spark plug wire boots. Even Hi-Temp wire boots got toasted.  :o

    Finally after 2 years of this frustration, I bought a 383 from a friend and put it in instead. Problem solved.  ;)

    Never did find out what was wrong with that "new" 400!  >:(

    I know exactly what you are talking about,  I had a car when I was younger (Not a Mopar!) and I shreadded the plastic timeing gear and I had to have every thing replaced, the guy showed me the oil pan with all the oil and plastic in it!!!  Also as for Wedge's 400, I have never really heard good things about the 400!!!  But to each there own!!!  Good luck Dark Horse hope the new pump works out for you!!!

    400 is a good engine and will hold up well. On the one that ran hot, well if it was puched out to much that can cause it to run hot. Also if the water passage was clogged. There are a lot of thing's that can cause it but that is more than likely a build problem, not a 400 problem.
