Ok here I have the intercooler removed on a S55 engine,,,,the customer complained that’s he is losing coolant for intercooler ,,,so I pressure tested the cooling system and found the intercooler is leaking internally.Here a picture inside the intercooler,,,you can see some coolant condensation on the walls of the cooler.

This was scary a F30 ,,,,,customer said the car got into a slight accident hit the curb and the insurance company fixed it,,,,they replaced the left front tire and wheel and had the car aligned and told the customer the car was fixed,,,customer took the vehicle and said it drives funny and making turns do not feel right,,,,I get the car and removed the lower engine panel and this is staring at me the EPS steering rack cracked in two,,,,lol,,,the insurance company had to buy a complete steering rack and eat the core charge because the old steering rack was not reuse able,,,,I can’t believe the guy the aligned the car didn’t see this or feel it when he drove it,,,,maybe he didn’t drive it after he aligned it.

Here a little video of the new Z4,,,,let me know what you think.

Here is the list of cars that have the 7/70 timing chain extension

Here’s a new type of starter for you,,,,this was on a X5 phev with a N20 engine,,,now we all know the starter has small drive teeth that spin the flywheel,,,,well we dint do that on this engine because the flywheel generates power for the battery’s Instead we use a belt that looks like a timing belt,,,it goes around the starter and the front lower crank pulley. Here is the lower front crankshaft pulley,,,it’s a different look for everyone

Here is the latest update you might find when you bring your car in for service on G12 and G30,,,turbo oil lines update. This is a picture of one of the old turbo oil lines as you can see the oil line is rubber and they have been known to start leaking oil.Here is a picture of both of the old oil lines removed,,,,one of the hoses was justed to weep oil.And here are the updated new turbo oil line that are now steel braided oil lines which will last a lot longer and take the heat better with the turbos.

Here’s a picture of the intake manifold off on a new B48 engine,,,customer came in car has no power and check engine light on,,,I checked faults and found coolant temp sensor and bank 1 knock sensor short circuit no signal,,,decided to look under the intake manifold. and thats where I saw the Rat damage which caused the customers problem.

Got this the other day,,,,E90 came in with check engine light on,,,,I could tell some kind of backyard mechanic has been working on this car and trying to fix the problem,,,,but they made the problem worse. The faults were lean mixture and airmass meter faults,,,,so I decided to smoke test the engine and found major leaks around the valve tropic motor and oil everywhere,,,,I removed the valvetronic motor and found it silconed in place with the whole gasket in 2 pieces and siliconed trying to seal it up with silicone,,,,,all they had to do is buy a new gasket and no more air leaks.

Here are pictures of the new B engines with a old style mechanical water pump,,,,as you can see some white dried up coolant leaking from the water pump. here are some more pictures of this fine new design water pump,,,,I don’t know why we went back to the old style water pump and go away from the newer style electric water pump.this new design gets better with a vacuum control flap,,,,this flap opens and closes off water going to and from the water pump,,,,we are seeing these water pump failing early this car had 15k miles.

Customer came in and said he ran over something,,,so I checked out the damage and saw customer tore away the lower fuel tank support bracket,,,the mounting bolts were tore away from the body,,,the customer is lucky no orange high voltage wiring were near by or damaged.
