HOW OFTEN SHOULD YOU CHANGE YOUR 911 GT3 SPARK PLUGS?

After reviewing the above, you may wonder why Porsche mandates such frequent spark plug changes on the 911 GT3.

There have been three engine revisions to the MA1.75 engine, the first 785 cars built used the E revision but all were recalled and replaced with the second F revision engine. There should be no E engines left as far as we are aware.

Some owners, particularly those who frequent the track and spend a lot of time near the 9,000RPM limiter have noticed misfires in the F revision engines. We’ve found valve train rocker arm defects at the source of this issue. Porsche offers all 991.1 GT3 owners a generous, 10-year, 120,000-mile warranty. If you are still within the warranty period, high RPM misfire issues may be resolved by an engine replacement to the latest G revision.

It’s important to follow Porsche’s maintenance guidelines strictly and to maintain service records so that any possible engine issues during this generous warranty period are covered. Once these issues started to become widespread, we noticed that Porsche updated its service schedule to include spark plug replacement every 12,000 miles. We suspect Porsche made this change to ensure that the engine has the lowest chance of developing misfires. Still, an engine that does exhibit misfires despite frequent spark plugs changes would qualify for replacement.

To ensure warranty coverage is maintained, we service all 991.1 GT3s with Porsche A40 approved engine oils and the recommended 999-170-153-91 spark plugs. Service records are kept on file that owners can request or access online at any time.

HOW OFTEN SHOULD YOU CHANGE THE AIR FILTERS ON YOUR 991.1 GT3 RS?

The 991.1 GT3 RS engine air filters sit behind the rear wheels and are fed directly by the large side air intakes. Rocks and other debris will hit the air filter surface, especially if the car is driven close behind other cars at high speeds, and will start to tear through the air filter surface. Porsche recommends changing the RS air filters every 6,000 miles to ensure that they don’t get clogged by debris or tear, allowing unfiltered air into the engine.

IMS Bearing

Virtually everyone who owns a 996 or 997 (Carrera 2/4/S/4S), 986 or 987 (Boxster/S), or 987C (Cayman/S) has heard of the IMS Bearing failure and many fear it so much that they barely drive their cars.  While the bearing certainly can fail, based on my experience the rate of failure is far lower than many would think from their online research.  I can count on one hand the number of catastrophic failures that have been in my shop and still have a couple digits leftover.  I have actually seen more cracked cylinder heads than IMS Bearing failures.  It must be noted that we use high quality Porsche approved motor oils and the correct OEM oil filters in our servicing.  We perform complete services for our clients as opposed to blindly changing out a few parts.  We also encourage oil services at 5K mile intervals or at least once per year on these models.  Proper servicing of the cars may not eliminate all problems, but it sure seems to help minimize them.

The RMS issues are often confused with IMS issues, so let us clarify the difference.

RMS – is the Rear Main Seal or flywheel seal of the engine on the crankshaft.  Although many engines were replaced under warranty for leakage at the RMS area this is typically not a catastrophic failure.  The engines that were replaced under warranty for RMS leakage were measured for proper location of the crankshaft and cradle within the case.  If they failed the prevailing test of the day then the engine was replaced.  If they passed, then they got a new rear main seal of the day.  I do not have enough fingers and toes to count the number of revisions to the seal, seal installation tool, and accepted case measuring techniques there have been over the years.  After all that, they still have a tendency to seep on most engines.  We recommend replacement or updating of the RMS and case bolts at the time of clutch or IMS bearing replacement.

IMS – refers to the InterMediate Shaft Bearing on the flywheel side of the engine, behind the IMS flange, and inside the intermediate shaft.  This is a single or dual row ball bearing which supports the intermediate shaft on a centering journal in the IMS flange at the flywheel side of the engine.  The intermediate shaft is driven by the crankshaft via chain directly over the IMS bearing and the IMS drives the bank 1 camshafts via chain at this end too.  The intermediate shaft drives the bank 2 camshafts via chain and directly drives the oil pump at the opposite end.  When the IMS Bearing fails or its centering journal breaks off the result is often considered catastrophic. Generally you will not only have the failed bearing but collateral damage requiring complete disassembly of the engine to repair. The damage can vary but the debris, which has contaminated the engine from the failed bearing, in itself necessitates a complete teardown of the engine.

Eurofix Flatsix offers bearing kits and installation services for all 996 and 986 Boxster models.  The 997 and 987 series cars cannot be retrofit without complete teardown. We   only utilize the bearing kits from LN Engineering since they have done extensive research to develop their bearings and we have established history installing these bearings.  This is a critical part of the engine and we are not interested in experimenting on your car.  The following kits are available with installation:

• Double Row Retrofit
• Single Row Retrofit
• Single Row Pro Retrofit
• IMS Solution

All installations are done using the proper tooling, with great respect to cleanliness, and proper torquing of all critical fasteners. This consistently insures the best possible results.

We offer a full range of heating and cooling system diagnostics, as well as heating system and air conditioning repair and service. Our trained technicians are also masters of belt, compressor, and evaporator repair and replacement.

The health of your vehicle’s cooling system is the key to engine longevity, your comfort, and comfort of your passengers. The radiator is the heart of your vehicle’s cooling system as it is responsible for reducing the heat generated from the coolant circulating through your vehicle’s cooling system. The radiator must be clean, leak free, clear of blockages, and filled with coolant. Coolant that is not maintained becomes acidic over time and degrades the internals of your cooling system. This deterioration of the cooling system’s components could leave you in an awkward circumstance. Ensure reliable daily driving and have your cooling system inspected.

Vehicles without a properly functioning air conditioning can be an unpleasant and uncomfortable ride in hot weather.  Furthermore, a properly functioning air conditioning system will remove humidity from the cabin of the vehicle in damp and cold weather so that visibility is not compromised in these situations.  Air conditioning systems have components that need regular check-ups to ensure there are no leaks, blockages, or parts that are worn out.  Stay comfy – come to EuroFix!
