If you suspect an oil pressure issue, you can use a mechanical oil pressure gauge and get a true reading of your oil pressure while the vehicle is running.
Theres a few tests you can do to see if you have head gasket issues or coolant leaks. You can use a coolant pressure tester kit. That will tell you if you have a leak if the gauge is showing that the system will not hold pressure. A compression test also will give an indication of a possible head gasket issue if two companion cylinders have low compression readings.
This is all on the basis of you stating you over heated the engine at one time.
Do you notice is ‘drinking’ coolant or seeing any white smoke?
No, The vehicle does not smoke at all. I am kind of suspicious of it being a head gasket, The vehicle over-heated once, over 2 years ago. I am now just seeing problems. I take it you would not recommend the motor flush. Would using a quart of automatic tranny fluid be any safer?
I’m with checking the actual oil pressure first to see where you are at but if you find issue there I don’t think replacing the oil pump will help, you’ll probably need to replace the engine, here is a video to help illustrate my point. BTW don’t bother with a rebuild as it’s way more expensive than just replacing the engine.
Using a good brand oil should have the adequate detergents inside for it to ‘clean’ the engine. Im not a fan of a ‘mechanic in a can’ products.
Head gasket issues would also cause over heating. You need to do some testing and gather some evidence C8-)
Yeah, I’m just gonna see what the problem is. I have no intention of putting more money into this vehicle. I’m planning on joining a credit union to get that 212 Kia Forte EX finianced at around 6%. $300 a month and after I finish my automotive technology classes in early 2014 I’ll probably sell it for whatever else I own on it, and get a better vehicle.
I would look at used vehicles if I were you. In 2 years you won’t be able to sell the kia for what you owe because of the huge depreciation on it.
Well I took the buick to my mechanic. He says theres nothing wrong with it. The 3.1L engine has piston slap and also is well known for oil taking longer than usual to reach the valve train. He also said since my coolant overflow tank is the one that came with the vehicle, the dark coolant is from 17 years of build up. The vehicle isn’t overheating, and the coolant in my radiator looks just as fresh as it did after I had it flushed 5 months ago.
I am considering looking at a used Toyota or Nissan instead of the Kia.
Thanks for the update. Interesting that those problems are ‘normal’ as I’ve driven cars twice that age without those problems. You might consider shopping for a replacement as you suggest.
Well I just took your word for it Eric. I went out to my car about an hour ago and took off the oil filler cap. I aimed a flashlight down in the hole, and all I could see was brown. Looked like burnt brownie mix all over the friggin place. I also saw a few spots underneath the valve cover looked like there was water pooled in the recesses. Is there any inexpsensive and safe way to clean the sludge out of my engine or am I S.O.L?
Quoted From rice400:
dont flush it, you’ll do more harm than good.
Yeah I know. The only safe way to use gunk motor flush is to take the oil pan off after draining the oil and clean the motor from the inside out. Talked some guy out of using it yesteday as he was bringing his vehicle in for an oil change. 1992 Ford Explorer with 250xxx miles. He would’ve destroyed his engine.
Would using marvel mystery oil or seafoam help? Is there another oil I can switch to that would slowly remove the sludge?
I’ve had bad experiences trying to ‘clean’ engines out as you can often take all the gunk and just send it down into the pan where it clogs up the oil pick up and starves the engine for oil. It may be too late for that engine if it’s making noise, you might just change the oil more frequently and perhaps add a little automatic transmission fluid (about half a quart) to help clean the deposits on the inside but I’d be hesitant to do more than that.
The engine has been making this noise for 30k miles. I found a video on youtube that sounds exactly the same as my engine…. But I don’t know how to link.
