Unsure I recently brought my 93 Astro, 4.3ltr, into Lubex to get an oil change as it was overdue and I was heading out of town for a 800k trip. They recomended an power flush of the crankcase. After about 150k's out of town I started hearing a knock from the engine so I turned around and brought the vehicle into a mechanic to have it checked out. He said he found a lot of metal in the oil pan and that a crank bearing was excessively worn. He suggested that Lubex possibly was at fault. He sent some pics to the engine rebuilder, engine is still under warranty, and the rebuilder sent a GM notice back indicating not to power flush engines.
Bulletin No.: 02-06-01-028
Date: August, 2002
INFORMATION
Subject:
Engine Crankcase Flush
Models:
2003 and Prior GM Cars and Trucks
2003 HUMMER H2
2003 and Prior Isuzu Light and Medium Duty Trucks with Gasoline Engines
General Motors is aware that some companies are marketing tools and equipment to support engine crankcase flush procedures. GM does NOT endorse or recommend crankcase flushing for any of its gasoline engines. Analysis of some of the materials used for crankcase flushing procedures indicate incompatibility with GM engine components and the potential for damage to some engine seals and bearings. Damage to engine components resulting from crankcase flushing procedures is not covered under the terms of the New Vehicle Warranty
I wonder now if Lubex is at fault.
Has anyone had similar experience or can offer some advice?
Thanks

Re: Lubex Power Flush Sign In

I would go back to Lubex with the service bulletin along with all service information you have on this vehicle.
These engine flushes are an easy sell for them using peoples thinking that cleaner is always better. If you had that much sludge in your engine that it requires a cleaner to try and remove it then the damage was already done.
But just like the bulletin says the chemicals they used may have caused this damage, it’ll be up to you to prove it was, by taking oil samples into a lab and having it analyzed for contamination.
I think you’ll have a long road in front of you, stay calm, use a professional mature attitude towards everyone and if they see you are serious about this you may get some satisfaction.
