Knocking under hood and low oil pressure?
For the past week or so I have noticed a knocking sound coming from under the hood. It isn't always present. When I first start the van I hear nothing, then after about 5-10min I hear it occassionally. When it is present it gets faster when I accelerate and slower when I let off the gas. Also for the past 2 days I have been getting a low oil pressure notice as well. The van only has 67,500 miles on it so I am not sure what could be going on. I know I need an oil change, but am only 100 miles past due and plan on getting one this weekend. Any ideas? I am really stressing about this
Sorry, It is a 2008 Chevy Uplander

In order to have HARMONI within your engien, yhou must use oils with BETTER RATINGS! DO NOT belive in VISCOSITY RATINGS ALONE! Rely on ILSAC< JASO< ACEA and GL rtatings! Many of todays cars REQURIE SPECIAL ADDITIVES within the oil they use! These PROPER oils have SPOECIFICATION NUMBERS that you must look for! AUDI?VW, e.g. need oil with the 502 and 505 NUMBERS printed on the label! FORD prodcuts do EXCELLENTLY with FORD RATED MOBIL ONE 0W-30 oils! YOUR ISIUE is either NOISY CLOGGED LIFTERS< or a NOISY CLOGGED UP HYDRAULIC TIMING CHAIN TENSIONER! Since you have NOT fully described your car, it is IMPOSSIBLE to give better, more focused advice here! ALl you say here is VAN! WHO MADE IT? anyways, yhou wlil need a FULL MOTOR FLUSHIGN to rid the engien of BAKED IN SLUDGE that resricts OIL FLOW through your engine parts! THEN USE ONLY SYNTHETIC OIL that has YOUR VEHICLE SPECIFICATI*ON NUBMERS printed on the LABEL! Stay away from ALL VALVOLINE PRODCUTS! NO FACTORY anywhere uses it, and it is a WAX REDCUTION OIL! This means that with TIME it turns into HARDENED WAX from which it is DERIVED>! mOST CARS MADE AFTER 2000 requrie full synthetic oil! Otherwise the warranty will be voided out! If you ahve MORE QUESTIONS use my E-mail address firstname.lastname@example.org or CALL ME at 248-818-6747! FEEL FREE! I have repiared cars over the INTERNET all over the WORLD< made by many car makers! The ANSWERS are usually ALL THE SAME anyways. BAD OIL PRESSURE is ALSO caused by POOR OIL CHOICES! It is NOT just the OIL CHANGE INTERVALS but the OIL CHOICES that are plaguing uyou NOW! ALL CARS have an OIL PRESSURE RELIEF VALVE< and if you can IMAGINE TAR forming on this from CHEAP OIL< you wll understand things more clearly! Once TAR is made from CHEAP OIL< you will get LOTS of engine noises! I have seen SUPEB TOYOTA ENGINES fail from CHEAP OIL CHANGES! sAME FO honda! sAME FOR vw/audi AND more! power wash yoru engien WITH gunk orange TO REMOVE all road salt AND CLEAN UP wiring harnesses< BETTERY CABLES AND connectors! fOCUS ON THE space BEHIND THE RADIATOR! mANY TIMES THIS ARES GETS clogged up WITIH LEAVES, SEEDLLINGS, ANIMAL DROIPPINGS AND insects! This causes SLOW DETERIORATION of tghe cooling system and EVENTUALLY oil will get TOO HOT< and makes the hardened SLDUGE that wil eventaully ruin your engine! PLEASE RA|EAD YOUR OWNER's MANUAL and GET SMART! The PROEPR OIL specification numbers for YOUR CAER will be found THERE!<<<YOU CANNOT GO WRONG with MOBIL ONE "0" series oils! They are SUPERB and PREVENT THESE ISSUES from ever happening! The GOOD NEWS is that oNE OIL CHANGE EACH YEAR wil give you MAXIMUM protection, LOWER FRICTION and MORE engien life! PENNZOIL ULTRA EURO gives a 15 year 500k OIL WARRANTY if you can FIND IT! AMSOIL is ANOTHER superb oil for modern car engiens GOOD LUCK andf get that OIL FLUSHIGN DONE! B-G makes a GREAT engien cleaner, and so does AMSOIL! If you have ANY more issues, contact me DIRECTLY at email@example.com!

Yep; you are on the deathly edge of making the car engine totally unfixable. If it runs you still have hope. Once it seizes"that ultimate final hard knock" and the engine stops running right there. You got something like a solid piece of metal. At that point it is "too late to see the best mechanic in the country". You got nothing.
So you go now and pay now because they can fix now. They can give you and estimate of how much it is going to cost you before they even start. But figure with a grand.

When is the last time (if ever) that you actually opened the hood and physically checked your engine's oil level? The "Knocking" sound you hear is probably one of your main connecting rod bearings trying to tell you that your engine is TOAST.

Engine oil thickens when it is is cool and thins when it is warm. Pinging can come come from engine knock from the wrong octane fuel or carbon build up in your cylinders. It can also can come from your timing be off. But those symptoms happen right away. Oil problems happen when the car warms up. Try Lucas Oil stabilzer they make one for conventional or synthetic oil. It will set you back about $5.00 try it see if it works for you. You can get this just about everywhere. Any auto supply store will have big box retailers have it to. Hope it works for you.
