Boxer major service extras??

Also retorque the heads, my 308 and boxer both needed it when checked. Also replace the carrier support O rings and axle seals, it also wouldnt hurt to yank the rear carrier and have it inspected for cracks around the welded end cap which could save you 20K in repairs down the road. This all drives the cost of the service up but saves you in the long run and gives peace of mind.

 

Lower cam drive bearings are a common problem on BB's. They do considerably more work but are the same parts as on a 308. All to often when I have replaced failed ones it was not long after someone did a belt service and we had to do it all over again. When the motor is out and the front apart it is an easy job.

Consider CV boots and take the distributor apart for a good cleaning and lubing.

 

I had the carbs rebuilt when we did mine. Of course, it needed the carb rebuild more than the major service!

 

I just completed a major on my BBi. I was told to seriously consider the differential upgrade by other local Boxer owners, as it is probably a matter of when, not if, the thing will fail. As I just bought my first Ferrari, this was initiation by fire. Both Rod Drew and Larry at Ferrari Tech (who completed the service) said they had never seen the diff fail on a Boxer, only the TR. While they are basically the same parts, the reason I was given is the Boxer just doesn't stress it enough with less hp and torque than the TR. Although I don't believe the diff failure is related to mileage, I decided against the diff upgrade. My car has 8300km on the original odometer, had never had an engine out service and had only been driven 300 miles in the past 9 years. Along with the normal engine out service items, mine included distributer rebuild, injectors, and CV boots. The inboard boots take a ton of heat just above the headers.
Probably jinxed myself, but I feel comfortable with the advice I got from Boxer experienced mechanics. I am climbing a steep learning curve familiarizing myself with my new Boxer, but what a thrill to own this car! I have owned it since Nov., so it will be nice to drive it now that it is finally in my garage.

Welcome to the club, you should consider adding your vin to the "just how many boxer owners" thread and show us some pics!

 

Welcome William and congrats on your car. I am also a relatively new Boxer owner and had the timing belts done along with carb rebuild etc. and chose to not have the differential upgrade. I learned about the possible differential failure after my car was done. I may have done it then, but chose to not have it done for now. I do drive the car often but with respect to it's age (1977 model year) meaning no smoky burnouts or snatching through the gears. I just wind it up progressively through the RPMs and the gears to give it a good running without thrashing the drivetrain. It seems to run much better the more it's driven. It takes a while for the car to warm so don't drive above 3000 RPM until the engine oil temp is up. At that engine speed, you can keep up with freeway traffic easily. The fast idle mechanism (if your car has one) will cut off when the water temp is about 80 or 90 degrees. Then you can enjoy it. You will have a great time learning how to drive it well. But the most important thing is to DRIVE IT!

 

all the things mentioned warrant a look . im doing a low mileage car and we pulled the water pump . i found the weep hole plugged and the start of much bigger problem . always check head torque and those cam drive bearings are becoming a very common service . check the dist to make sure advance is working . i tend to check mixture control plungers more these days on cars that have old/poor fuel . they stick and thats another oops ! . forza check for puffy coolant hoses

 

The rear differential / carrier. Its the thing that breaks without notice. Since the engine is out pulling the diff out isnt much more work and you dont have to seperate the engine/gearbox to do it. The axle seals should be done, the O rings that seal the carrier supports to the gearbox should be too. With them out you can see the carrier, remove the rear housing ahead of the flywheel and out comes the carrier. I would at least magnaflux it for peace of mind.

 

that's some nice peace of mind...records are nice!
