BMW 535 GT Repair | BMW 535 GT Maintenance

BMW repair many occasions requires an inside knowledge and decades of experience. Knowing what are the weak spots  of the BMW, comes whit knowledge and experience, hence we can prevent an expensive breakdown in the near future.

BMW 535-GT Front Propeller Shaft Failure

Here is a perfect example of a 535-GT front propeller shaft failure which is a typical issue on most BMW with accumulated kilometers on it.

This particular vehicle is maintained by its owner, we only see this vehicle when it’s broken. In this case not performing a preventative maintenance, cost almost an engine replacement, as the seized propeller shaft finally let go and punched a gigantic hole into the oil pan.

When We Service BMW 535 We Remove This Shafts

When we service BMW 535s we remove this shafts on the regular basis to check the U joint condition. In fact we even have replacement universal joint in house to repair this shafts as some of them cost some silly money from the manufacturer.

On this BMW we had a hard time to source a proper exact replacement oil pan and ditto for the front propeller shaft.

The owner got lucky, he managed to shut the engine down in a hurry, which saved his N55 engine. He said when the shaft broke he killed the engine instantly.

Either way we would not know if there is or has been any internal engine damage to the crankshaft or the bottom end bearings.

We had to come up with some clever solutions to test the engine, to be able to confirm the engine did survive the ordeal. Therefore we cleaned the broken oil pan with a de-greaser.  Let it dry and remove any oily residue, applied windshield glue to the open area around the hole and glued a heavy plastic sheet over on it, and let it cure overnight .

BMW N55  Engine Repair

Next day we removed the oil filter and filled up the channel with fresh motor oil quickly. When the engine had proper amount of oil in, we started her up instantly.

The engine run properly without any noise or sign of excessive wear. At this point we knew we can proceed with the proper repair and resurrect this vehicle to it’s former glory.

BMW N55 Engine Connecting Rod Bearings Replacement

Needless to say we will remove and replace the bottom end connecting rod bearings with new performance bearings,  just in case. Additionally the new performance bearings are superior design made with improved materials compared to the genuine bearings design.

It just makes perfect sense to replace them while we have the bottom end open. It’s a simple procedure at this occasion.

Motor Work On BMW

The right tool for the right job. Correct? This sentence apply for motor work on BMW Merced, Porsche, and on MINI to.

Motor work on BMW, Porsche, Audi, Mini.

Having the right tool for the right job is essential in most cases. No shiny toolbox will ever fix any BMW if doesn’t have the right tools within.

The another day we had a persistent tank ventilation system leak on a newly acquired 2011 BMW 3 series. First we had the vent test pump failed and the fault kept returning.  After pumping a lot of smoke into the system we found someone hammered on the tightening ring onto the fuel pump assembly.

Unfortunately there was a chunk of the pump housing missing so we had to replace the pump assembly with a new ring and secured it with the proper tool.

BMW X5 N55 Engine Repair

Today, one of our clients BMW with an N55 engine required a special repair. We had to fabricate a special tool to extract the seized, severely corroded fuel injector from the cylinder head.

In this case, the factory injector puller is not adequate to make the injectors budge from their hole. This is a common issue on BMW X5 trucks with the N55 engine. In this case I had to solve the issue by fabricating a custom puller to extract the fused injectors from the cylinder head, without the removal of the cylinder head assembly.

Needless to say we were successful to resolve the issue at hand, and we saved a lot of time and $$$$ for our client.

BMW 535ix low oil pressure warning

The perils of using the wrong method trying to correct the problem. We received this BMW 535ix with low oil pressure warning related to a known issue which started from a common oil leak the filter pedestal and cooler gaskets.

Maintenance on BMW N55 Engines

This considered a common “maintenance ” type of work on the BMW N55 engines. We charge $450.00 to replace both gaskets, and only viable part is the revised genuine gasket, it will hold up better in the future.

The technician working prior on this engine, (the vehicle has been towed from a another garage), had this “clever” idea to just apply silicone sealant.  Unfortunately in a futile attempt, that made the leak actually worse, which resulted in the classic usual result.

When the belt gets soaked long enough with motor oil, it will shred and gets grabbed by the crankshaft and whipped up into a ball or cord and rubber.  It gets pushed thru the front crankshaft seal,  the timing chain will grab it and the whole thing gets ingested by the engine.

You can imagine what happens with a bunch of cord and rubber, when it gets shredded internally by the timing chain, it creates a complete disaster. Now to fix this,  the entire bottom below the oil pan needs to be removed, like axles, differential, the steering rack control arms, the engine mounts and the sub-frame assembly to expose the oil pan.

BMW Gasket Replacement

Naturally the top engine cover, the valve cover has to come off as well, including all the high pressure fuel lines and rail and so forth. The rather mundane gasket replacement turned into a partial engine overhaul, where we have to remove the oil pump and must inspect the connecting rod bearings for excessive wear, due to oil pump suction pipe restriction by the belt pieces.

We went from a $450.00 dollar job to a 6 thousand dollar engine recovery and major resurrection. They tried to fix the oil leak, replaced the front seal the wrong way, as well as by removing the center bolt holding the timing chain sprocket in place by friction.

BMW Camshaft & Timing

Needless to say the camshaft timing was moved as the vehicle would need to be set up with a special jig to be precisely timed for proper operation. Worth to note, the center bolt must be replaced, as it’s a single use stretch bolt, or it could cause major engine damage.

We have documented all the problems, detailed with plenty of pictures.
