Most likely future problems

Recommended Posts

Regular/known faults with the Mkiv are very few and far between.

 

Things that wear out like Crank pulleys, coil packs and wheel bearings are the few things that seem to be more talked about more than in years gone by.........

 

what other items/parts do you think will become an issue in the next few years. I'm thinking wishbones, engine mounts maybe anything else spring to mind?

Recently had the crank pulley literally break in two pieces as they do.

 

Also, power steering failed a few months ago. Fitted a second hand pump, didn't work! Sent my pump for refurb, didn't work! Sent rack for refurb, didn't work! Pump sent back, found was still faulty, re-refurbed and fitted, didn't work!

 

Turns out after all that, air was still in the system when parts refitted and took mechanic half an hour to work it out of there. In the end it wasn't exactly clear which component was faulty, but all works fine now and hopefully wont happen again for another 10 years!

 

Apart from that, runs like a dream.

Things that spring to mind:

 

Front crank pulley - rubber failure.

Turbo oil seals - leaking.

Valve seals - leaking.

Rear wheel bearings - replacement.

Sticky brake calipers/pins (J-spec) - refurb / replace.

Cracked brake calipers (around bleed nipple - J-spec???) - replace.

Boot rubbers - replace.

Front and rear anti roll bar drop links - replace.

PAS pump - replace.

Water pump, Bearings (big ends, Cam shaft, prop), Headgasket?, exhuast manifold gaskets, oil pump, valve Shims, Piston rings...

 

Depends on your millage/driving style and luck really lol

Erm, not exactly common faults on a 2JZ... In fact almost unheard of!!!

Yep, I think more often than not the pesky N/S rear wheel bearings are already showing a trend for the worse.

 

Bushes are getting crusty and droplinks will probably start to show their age, especially with everyone going with aftermarket wheels these days.

 

My dust boots have also disappeared without a trace...

 

And ceramic tubbies may become rarer by the day.

 

Still, 12 years and going strong despite all of these things! :)

Guys, there's weak points and then there's parts that suffer wear and tear. Please make sure you distiguish between them.

 

Lets face it on an upto 14year old car everything that moves, expands and contracts can fail.

 

and remember these cars will no doubt still have a following if a classic/modern classic one, in another 10 years of time - Hence my list of things that will go eventially on the engine and drive train that is over 25 yrs old..

A lot more that are plastic and rubber related are past their best and can lead to performance and aesthetic issues. A few examples would be coil pack clips disintegrating. Engine bay loom clips crumbling. Rocker breather hoses becoming fossilised. Door cards splitting on the lower seams. Dash splitting at the window edge. Boot plastic clips breaking when panels are removed. Rocker cover gaskets leaking. Valve stem seals worn out.

 

Then with rust the fuel tank breather pipe corroding away. Fuel tank guard corroding from the inside. The front to rear fuel and brake lines corroding. Back of diff to sub-frame mounts going soft potentially leading to transmission hop.
