Classic Porsche Engine Repair in Pennington, NJ

The Porsche air-cooled engine is a piece of timeless automotive machinery. The Porsche 911 was powered by an air-cooled engine until 1998. Air-cooled engines, although very simple to tenured technicians, may be a headscratcher to the newer generation of technicians. Many Porsche dealerships have moved away from working on air-cooled 911 engines, leaving many people have been displaced. One of the important talking point to remember is that most owners of these types of classic Porsches look for a specialist and technician that has internal engine knowledge. The reason for this? Simple, the likelihood of having to remove the engine to do certain repairs is very high.

Most of these cars do not get driven a lot and are “nice weather vehicles.” They will typically sit in the garage for half of the year during the winter months and come out of hibernation for the summer. Most people do not think that this is problematic. The issue is that over time, lack of use causes gaskets to shrink. When this happens, after starting the engine, the gaskets will expand. When this happens repeatedly over time, fluid will leak and the gaskets will no longer serve their purpose. There are several common areas of leakage:

Valve cover gaskets leak which causes oil to burn onto the exhaust
Valve stem seals leak internally in the cylinder head
Cylinder head gaskets leak externally
The rear main seal will leak, filling up the bell housing of the transmission with fluid and then leak out from where the engine and transmission come together.

How to Inspect for Leaks

When your Porsche is serviced by a trained technician, a complete multi-point inspection is performed. Any underbody shields will be removed so that there is complete access to the underbody of the vehicle so it may be inspected for leaks. Any residual fluid will be cleaned and a fluorescent dye is administered to the fluid system. Then with ultra-violet light (similar to a CSI investigation), the areas may be inspected to find the source of the leak, that way the area of leakage can be determined and an accurate estimate may be provided for performing the repair. Photo documentation of the inspection is done as well to maintain a proper health record for the vehicle. A proper repair will include cleaning and degreasing the affected areas and make sure that there is no residual oil left anywhere.

In great condition, a classic base-model Porsche can fetch $30,000 and certain editions can bring over $70,000! Most Porsche enthusiasts think of them as a 401k that they can have fun with before cashing out.

Here are some reasons why these air-cooled 911’s are so great:

Air-cooled engines are light weight, attributing to the vehicle’s speed
A light weight car is more nimble and can be a lot of fun to drive, both on the track and on the street
The sound that an air-cooled engine makes is like no other engine, and at higher RPM’s can “Sooth the Soul”
It’s a timeless look when the bonnet is open
An air-cooled engine is far less expensive to maintain or repair than its successor
There is not a liquid cooling system that needs to be maintained or repaired
Always remember: Keep those tires spinnin’ and your face grinnin’!

Mini Cooper Intake Valves

January 3, 2025

Carbon Build-up Over the past few months we’ve seen a fluctuation of clients experiencing problems with their Mini Coopers due to carbon build-up in the intake valves. The cars that have this problem exhibit a range of symptoms from a rough idle or misfire condition to a check engine light. Though this problem can happen on some other BMW products, we’ve noticed it most recently on Minis with the 1.6 liter (4 cylinder) direct injection motor. Some people may describe the symptom they experience as a surging, jerking, hiccup, or misfire. Sometimes it happens when the car is started cold in the morning, sometimes it happens while driving the car. To remedy these symptoms, a carbon cleaning procedure must be performed where the intake valves are de-carboned with walnut blast media and in some cases would include replacement of the spark plugs and ignition coils, if necessary. A preventative measure we like to recommend is to replace the engine oil more frequently than what the manufacturer recommends. Doing an oil change every 7,500 miles is acceptable, but every 5,000 miles is ideal.

The Importance of Properly Inflated Tires

December 23, 2024

Why Should I Keep My Tires Properly Inflated? Your vehicle’s tires are among its most important safety features. You must keep all four tires properly inflated to stay safe and secure behind the wheel. This reduces your risk of an automotive accident, extends the life of your tires, and saves you more money in the long run. The PSI refers to the minimum air your car’s tires need. This number can be found on a sticker inside your owner’s manual or on the driver’s side door jam. Here at Union Line Garage in Pennington, New Jersey, we recommend checking your tire pressure weekly to ensure each tire is properly inflated. The Dangers of Under and Over Tire Inflation Your tires should always be inflated to exact specifications. If your tires are under-inflated, your car will experience: Premature tire wear and tear A 25% reduction in tire life Poor control and stability Poor fuel economy A higher risk of tire damage if you drive over debris or potholes On the other hand, over-inflated tires can cause: Poor handling and control An increased risk of blowouts because of the excessive pressure A higher risk of damage if you drive over potholes or road debris To prevent tire under- or over-inflation, check your tire pressure once a week. Always check the tire pressure before a long road trip. When checking the tire pressure, use a high-quality pressure gauge. These typically cost around $15 and can be purchased at any automotive store. Follow the tire pressure in your owner’s manual, not the pressure on the tire sidewall. It is best to check your tire pressure before driving your car, not when the tires are hot. This can increase the PSI. If your tire pressure is continuously low, it might indicate a leak.
