yes. So were the cam belts and seals changed on your Boxer last year on the cheap with the engine still in the car so the tensioner bearings were not changed and they have now failed? See my reponse to your other post.

 

Depends.......is the engine already out of the car?

 

That would tell you the previous tech did belts only without the tensioners......change vendors!

 

One year, no. I would make sure I did everything that was needed but I would leave all that more recent stuff alone. Replace that belt and tensioner and put it back. If when it was out last, if the lower cam drive bearings were not replaced I would do them. They are the same as 308 but due to the extra 4 cylinders do not last as long. Half of the BB motors I pull out are for that reason alone.

 

Actually, the belts were changed on my boxer last year, and the mech. says he removed the engine, but didn't do the seals b/c they looked fine and weren't leaking........a major had been done two years before I think "on the cheap".....what do you guys think of removing the engine and just doing the belts and bearings? I will withhold comment.........

 

And it actually was 3yrs since the cheap job.......does that change things?

 

Is there anything wrong with it now?

 

he has started simultaneous threads, he's had a tensioner fail.......

 

sorry, not fail, get loud..........

 

I took it to a different shop, and had three different mechanics tell me the engine had not been out of the car......lots of leaks, etc

 

that's a clue!

 

no failure......i will explain at the end

 

i first had my car done at shelton many yuears ago when I bought it. the car didnt run above 5000 rpm and the tensioners made noise from day one. It was not a cheap job either. I spent a fortune sorting their ineptitude bit by bit.

Nevertheless those noisy bearings lasted untill the next engine out 7 years later. That being said if its on your mind do the job properly and you will avoid that little voice of doubt each time you go out. There is a huge difference in the way boxers can run. If it hasent been sorted properly I'll bet the distributor weights are frozen too, and what about the water pump? are the fuel hoses new? . If you drive hard bite the bullet and do it right. It'll run as is but whats the point.

 

Ok.....so let's say it was not a cheapy job, a tensioner bearing goes south, no catastrophic failure, just a sound that's not right.....so three years after the service, you have the engine out.......what work should be performed for this service? And could the bearing/belt replacement be done with the engine in the car?

 

All this was happening on your car after a major service? How long after the service?

 

sheesh, glad i work on my stuff myself or with friends. scary thread, given i want a Boxer.

 

Amen

 

They can spring leaks like a screen door in a submarine, bro!

That's why if you are gonna touch 'em you throw the engine out on the floor and DO EVERYTHING!

....and know back to our story..

 

Do everything huh? Hey kgoose, you here this! Bigtex, so am I right in saying that for $12,000 my cam seals, water pump, etc should have been done in addition to belts and tensioners?

 

Am I in an arguement here????? I'm gonna move to Switzerland!

A service for a Ferrari should follow the printed regimen from the Manual, for best results.....it's clearly delineated there, what should be performed..

That said, the warranty on service on the cars lasts until the first turn of the steering wheel, at which time anything can go wrong, and sometimes does......

We've done post service diagnostics on cars where the $12K apparently covered a thin sheen of WD40........so beware!

The Boxers are big cars for big boys......faint of heart, or wallet, need not apply......
