I decided to create a new thread on the junk CVMS is putting out their door. I want make sure my post pops up when someone is looking at CVMS.
I waited to make this post as I wanted to have all of the facts before writing. It’s a long post but I wanted to give details to the unsatisfactory workmanship by CVMS on my 389.
I installed and ran my freshly rebuilt CVMS motor June – October putting 2,437 miles on the motor during this period. Throughout this time the engine would consume 1 qt. of oil every 150 -175 miles. While I would see wisps of smoke through the exhaust at times when accelerating, it wasn’t alarming. I did contact Jim L. and told him the motor was running great but I was concerned about the excessive oil consumption. Jim told me "to keep driving it as the rings weren’t seated". He also told me when driving "put the car in 2nd gear run the motor to 5,000 RPM’s, let off the accelerator and allow the engine to brake itself, this will put vacuum on the cylinders and help seat the rings". I did this many times seeing a little smoke during acceleration and lots of smoke during deceleration. Jim was informed of my observations and he stated to “keep on doing this as the vacuum would help seat the rings”.
As oil consumption was not improving Jim believed the valve stem seals were allowing oil to be sucked back into the exhaust valves (?) which was why the motor was smoking so much during deceleration. Jim told me to find a good engine builder in my area to replace the seals, which he would provide and pay for the labor (which he did).
During my summer driving I was able to meet many Pontiac enthusiasts who highly recommended Mueller Auto in Auburn MI. I contacted them and arranged to have the seals replaced on 10/14/2016. When I picked up the car Don Mueller told me that he didn’t believe that this would correct my problem as when adjusting the valves the guide plates didn’t look like they were setting at the same height. He also told me that when doing compression tests cylinders 1&5 had ~45% leak down. I contacted Jim on 10/19/2016 with this information which he didn’t believe and told me to keep “driving the car” which I did.
From 10/14/2016 – 10/27/2016 I put another 483 miles on the motor which was running good but still smoked and used 3 qts. of oil. I contacted Jim on 10/27/2016 and informed him of this again with the same reply, “keep driving the car”. I put another 218 miles on the car in 2 days using 1.5 qts of oil. As my wife and I were leaving for a 2 week vacation I contacted Don Mueller in the late afternoon on 10/28/2016 about dropping the car for repairs based on what he had discovered. I did not contact Jim prior to doing this. As I was going to be out of the USA for the next two weeks I asked Don to contact me VIA e-mail.
On 11/02/2016 I received this e-mail from Don Mueller:

Steve we have your Pontiac motor apart and it is not good the Pistons were installed backwards the valve job is terrible the camshaft is wiping out the block was shot blasted and never line honed or decked we need to replace the Pistons line hone the block and rehone it and reassemble it and do a valve job the crank needs to be reground that being said you will have about $4,200 to complete it. If you could call me that would be great. Don Mueller. I didn't expect to have to do a complete rebuild!”
I replied to continue with the rebuild as I needed the motor. I also forwarded this note to Jim on the same day with my comment:

As we're on vacation I took the GTO to Mueller Auto for engine work. They are a very reputable machine/auto shop in our area and I don't dispute what they have discovered. I'm very surprised and very disappointed.
I know what the CVMS warranty states, but are you willing to cover half of these expenses? Please let me know and I will give you a call when we get home to discuss.
When I picked up my car from Mueller’s on 11/25/2016 some additional hand written notes stated:
Pistons installed backwards.
Rings have heavy wear from incorrect side loading. Main bearings wiping hard, #4
grooved from debris, bead blast residue.
Block was not line honed after bead blasting.
Heli coils in head were holding guide plates up allowing oil into oil intake runners. (I had CVMS replace the pressed in studs with 7/16” screw in studs and 5/16" guide plates).
Crank needs regrinding.
On 11/26/2016 I e-mailed Jim copies of invoices with descriptions of work completed and the parts that were replaced. I told him I would contact him sometime this week.
I contacted Jim on 11/29/2016 to discuss the engine. Without going into too much detail Jim felt I overreacted to the issue, he felt insulted as he knows the engine was put together correctly (IE pistons), he has pictures to document this (as do I as he sent me pictures of my motor during the assembly process) and I just should have brought the motor back to him for repairs at no cost, (I didn’t tell him I wouldn’t spend another 24 hrs. on the road to deliver the motor and another 24 hrs. on the road when picking it up just to have another poor rebuild). He stated “The guy doing your work is probably a Chevy guy and doesn’t know anything about Pontiac motors. I suggest you go get all of your engine parts now before you have an engine that won’t last a year is completed”. I replied “the rebuild is complete and the motor is in the car and I’m not concerned as it is now under Mueller’s warranty”. I asked Jim if he would cover the rebuild under the CVMS warranty and he stated “no”. I ended the phone call with a “take care”.
I do not like to provide negative feedback about any individual/company unless it is warranted. Therefore, I cannot/will not recommend CVMS for any type of service. The quality of their product sucks and people who want a quality rebuilt Pontiac motor should NOT contact Central Virginia Machine Service. I paid CVMS $6,000 for a fresh motor, I paid Mueller’s Auto $4,300 for that same fresh motor, which included a dyno test. That’s a lot of $$$ for a stock 389 Pontiac.
It was suggested to me when my motor was at CVMS “go pick it up before they do any damage to it!”. It was too late at that time. It’s ironic, as Jim L. suggested the same thing to me.
