Recent UIM/LIM repair...since low oil pressure..now knocks?!
 

not too long ago i had UIM LIM failure. THat has since been repaired. After the repair i obviously changed the oil after a few hundered miles. Like an idiot i bought an engine oil additive i hadn't used before. It seemed that the additive i bought went in thick but came out runny. I have sinced changed that oil out and put regular in. BUT the oil pressure still drops when the car warms up. Now just today my engine started knocking and the oil pressure woes continue. I noticed my car seemed a lil underpowered then i noticed the knock. I checked all the plugs hoping i just fouled one but no. Please can someone help me!? is this possible result of the UIM repair? if so it will be covered but otherwise i can't figure this out and REALLY can't afford another large $$ repair.
please please help!

When water gets in your bearings bad things happen....speaking from first hand expierence.


what sorta oil pressure numbers are we talking about?

well when the engine is cold...norm about midway then when it heats up it starts dropping and for a while it hovers above the low line (just before the red) while idling then goes up when i motor. Then when the car heats up completely it goes into the red when i stop....although it still runs fine...well it did until now it started knocking...i was gonna change the oil again to see if that would help...maybe switch to 5w30 but the knocking started today so now im worried. but yeah when the car is warm the pressure goes LOW then fluxes back to midway

Change your oil again. NOW!!! If you're going to switch oil, rather than changing weight, switch to synthetic. The "better cleaning properties" might help some.

About 6 months after my UIM went, I lost the whole engine. Apparently, the repair was not done soon enough, and the coolant that got into the system had time to start it's evil rot trick. The engine basically ate itself due to internal rust for about 6 months, and finally blew (taking the tranny out with it)

Get some good clean oil in there quick! Not sure how much it will help, but it can't hurt to get out whatever left over contaminants might still be in there.

Good luck, mn. I hope I am over reacting based on my own bad luck.

If the engine is knocking, changing the oil is just more money spent on a losing battle. You are likely losing your engine.

The Gearheads are currently discussing the possibility of asking people to drop their oil pans after the failure, as the oil pan can hold over an inch of water below the drain plug and circulate it back through the engine.

Actually..w/o measuring it looks to be 1/4 to a 1/2 inch. In reality..any significant amount is potentially bad.

I'm up for that task! My oil pan gasket is leaking a tad bit. Will let ya all know about it sooner or later.

Mike..see my comments here about oil pan gaskets

ok ..but i cant afford a new engine...nor a car right now...any other suggestions? i can easily change the oil to synthetic..but what kind 10w30 synthetic? please i dont want to lose my car...my rear drive hub went last fall...thus rebuilt tranny...then UIM/LIM this spring...the last thing i need is a new engine. Please please help

Do you know of a reputable shop? If so ..stop on by and ask them about putting new bearings into the motor. Do this quickly. The best chance to do this is right away. No more running than necessary.

yeah i just called my tuffy near by...i hate to drive it now that the knocking has started. But they said they'd inspect and estimate me for free. So anything else i should watch for when i bring it in to them?

Orty, whether you can afford it or not, the fact is that you have a bottom end failure. No brand or type of oil in the world can help you at this point.

okay answer me this...could this have been because improper procedure by the shop that fixed my LIM/UIM failure?? if so then i am covered.

They likely did the procedure correctly. However, it wasn't detected until it was too late. Damage had already set in on those bearings.

Not necessarily. This is the result of the FIRST failure. Not the repair.

ugggh...well hopefully im crazy and its not as bad as i am making it sound...ill be driving to Tuffy now...ill post when i get back so you guys can no whether im going to shoot myself and my bonnie or not

Uhm...we would prefer you don't shoot either. We can psot pictures of rice if you Must shoot at a car to relieve your frustration. :)

But seriously, I wish you better luck than you've had so far.

Unfortunately, that's what I was told as well. The job was done properly, just not fast enough. That's the worst part of a UIM failure, it can be bad for quite a while before the symptoms become noticeable.

Again, tho, good luck! I really hope we are all over-reacting!!!

well the guy at tuffy only heard my car for about a second before he diagnosed. Yep lower end...thus bearing. He just picked up a used 3800 and said i can do that but...i dont have the money or the time. I'll prolly just end up driving it until it dies and then buy/use a friends old car he has until i can afford a new car. Unless a forum member will make me an offer i cant refuse for my 95 green SSE (sig car) but alas she is very sick

Orty, where are you located?

It's not that sick...

Did you ask about changing just the bearings?

grand haven / holland area in michigan

Sorry to hear about all of this.

How much are you looking to get out of it?

i really have no idea...but the more i find out about my friends cars the more i will know about what to do with my bonnie. If i could sell it to a club member still running i know that would help...but prices i have no idea as i dont know how much it will cost to fix/ buy put in a new motor.

bump

What information are you looking for?

idk you asked how much im looking for and i responded

I'm still not sure what you're getting at! :lol:

PM me and we'll take this offline.
