When I drive hard on the open road, I usually do a lot of engine braking ...from 3rd ...make the needle drop from 5k rpm...then 2nd....lastly apply the brakes. Of course I do this on long stretches which gives me time to downshift and all.

Question is... what are the usual wear and tear issues of this habit? clutch? camshafts?

Any pros and cons ?

 

If you are driving hard trust me you aren't doing anymore wear and tear by using you engine to slow you down. Don't just down shift, it's better to try to rev match.

I understand what you mean and I try to match the rev once in awhile. All am saying is, when you hear the engine roaring from engine braking, is it wearing or tearing something up?

IM not a big fan of clutch in/ heavy foot braking. I think its completely a waster of pads when you drive it for everyday use. (unless you drive an auto I guess)

 

you rather buy a valvetrain instead?
engine braking without revmatching is very bad to the valvetrain, specially the valvesprings

 

Of course, I try to rev match it. Thats my concern. I feather on the brakes, but gently downshift when i try to slow the car down. I also change the gears one at a time when I know its slowing down.

I don't downshift and make the needle fly to 5 or 6k.

I just want to know what part of engine gets most of the stress? Aside from the valvetrain, does the clutch have a chance of geting busted?

 

the clutch wears as well a lot.
But if you are revmatching and being gentle and not ''shocking'' the engine you should be ok.
