Post/Pre Purchase Inspection

We love to see avid enthusiast and daily commuters alike get new cars. Being excited about the purchase, and having good knowledge their dream car is just that, not a nightmare.

For years, we have been doing PPIs (Pre-Purchase Inspections) to help buyer confidently put down healthy sums with confidence. With the desirability of some of the air-cooled Porsche makes we have see values climb at a staggering rate, and the number available shrink leaving the price to go up. With this elevation of desire and market value comes the wild claims of originality, and people trying to sell through dishonesty and misrepresentation. Recently, we had a vehicle come in to our shop that illustrates this very well.

We received a call from Texas to help a gentleman out who had found his dream Midnight Blue Porsche 993 Turbo here in the region. It really was a stunning car, and it’s no wonder why these beautiful cars continue to climb in value. At initial glance, it was a clean car that was not being sold as a salvage title or was sold as wrecked. No damage really to speak of, it was seemed to be an honest car. Clean Car Fax with no indication of collision.

With the PPI process we look over the vehicles with keen eye on the details, corners, any over-spray especially in the rocker panel regions or place where their are post-paint body plugs. These areas can tell many stories about the past of a car. The car was being listed at approximately $90,000 USD, and was high for the market. This was not being listed by a private owner, but a business.

This is what we found:

Rain Guards: Tack-welds the entire length when they should be smooth. This indicates that, at one point, the car had been split at the seam to allow a panel replacement.

Door/Door Sills: The sills had a bump/step in them likely from the replacement panel overlap. The door gap wasn’t uniform. Under the door sill was where shops will hide the welds… we found welds.

Back deck Rail: Where the rear quarter panel meets the trunk stamping it was not factory clean spot welds, but a smoothed over area with body filler to hide the repair. In addition, this area had paint cracking the entire length.

Tail Lights: The three lights that make up the rear didn’t align properly, and was a clear indicator that the angle of one panel in the replacement wan’t quite perfect. The passenger side rubber gasket wasn’t touching the body to seal this area. In stead the gap was too large, and not able to be rectified correctly.

Rocker Panels: The rockers revealed non-factory over-spray that had been sprayed over air-conditioning lines. These are installed after paint at the factory and should be clean, bare aluminum. There we found the primered replacement panel fresh edge that didn’t receive paint. This is a key indicator that this car was clearly wrecked.

After deliberation, we called the client to tell them the news. We advised to not perform a leak-down test on the engine after this gross misrepresentation. He was clearly disappointed with the findings, however, he saved money by not performing the leak-down test, and furthermore, tens of thousands of dollars in a car that is not worth the asking price.

The following day we performed a Post-Purchase Inspection for a young man that had purchased his first M3. The car was a great deal to begin with, and he needed and oil change. He had P3 Autokräfte inspect the car, and insure that he had a solid car to start with, and let him know if there was anything that needed addressing. He had found a quality car. Money well spend, and good peace-of-mind.

If you are looking at a used vehicle please let us know how we can help insure that you receiving the car of your dreams.

Mini Cooper – Chain Tensioner Troubles

P3 Autokrafte is primarily a Porsche and BMW facility which also services Audi and Volkswagen. We can’t forget the fantastic little brother under the BMW umbrella; Mini.  Without a Mini specific dealer in the Dayton Area, some Mini owners may feel a bit underserved. That’s where we come in to help.

If you are on the Mini forums, and are enthusiasts like we are, you know about the potential damage of a tensioner failure. With Mini Coopers, Clubmans, and Countrys on their second, third or even fourth owners, sometimes critical info doesn’t get passed down about the items in a recall or recommended dealer services. Not everyone in an enthusiast, so we want to spread the word. Preventative maintenance is key to trouble-free years of use, and ‘failure’ will not be in your future.

Depending on how you search or what part you believe to be the first to fail they are all interconnected; VANOS, cams, tensioner, vac pump, chain, pulleys, guides, etc. Each one of these can be affected with a catastrophic failure, and you can then throw in the valves, head, etc, etc. This is not a pretty picture to be painted, but we wanted to bring this to light before it’s the case for your Mini. There have been recalls on the chain and tensioner since the inception of the Mini, they have made a change to the tensioner and the chain to hopefully prevent this in the future. When it comes to Minis with the R56 motors we recommend changing the tensioner, and closer oil change intervals.

We see the chain, tensioner, and guides as a routine maintenance items that should be replaced (before 100k for the standard Mini and 60k for the S). Some recommend it sooner, but keeping a close ear to any rattling before these intervals; especially noises within the few seconds after start are good indicators that you should have it inspected. It’s a fairly inexpensive service, and should be considered like a water pump replacement or other long duration component in your service intervals. The Mini the tensioner, chain, and guides are relatively inexpensive parts. This can cost-effectively be added into your Inspection 2 services.

We recently received a Mini that had gone ‘a bit too long’ before addressing. The result was not pretty, and the service became a major overhaul. When the first component failed it caused the chain to break, the motor to skip timing, bend exhaust valves, fail the vac pump, etc, etc. It was a mess. After a re-machining on the head, full top-end re-build, new tensioner, VANOS actuator, vac pump, and a number of other affected items, and re-sync the cams, and VANOS sensors, it is back on the road like a champion.

We wanted to make this information as accessible as possible for Mini owners, so we can keep you on the road and out of the shop. Below is a breakdown for a widely accepted Mini Service descriptions  and intervals. Please feel free to call us to schedule and appointment, or discuss the details of your Mini.
