It goes from bad to annoying

[D3ft0n3s]

So got my spark issue fixed, my mechanic mentioned that there is a leak in the main oil seal, and on the passengers side tappet cover.

Anyone wanna help me fix it for a box (or more than one) or piss? Timaru or close area

EVOWRX ill get you model numbers for seals

Follow up the lead I pmd yday.

[D3ft0n3s]

also now that firing issue is fixed it keeps cutting boost in every gear can hear bov engaging. any ideas?

its like it hits boost and goes booooooooooooost psh boooooooooooooost psh boooooooooost psh, all the way through rev range, (still goes like fuck!) what would cause this?

[D3ft0n3s]

Also, here is all the model related shit for th car :

Engine EJ205NM4BA

Model GDABK8D

Transmission TY754VN2AA

Got a boost gauge installed? Whats the max boost its hitting?

[rex-leggy]

gta be boost cut

[D3ft0n3s]

ok no boost guage on the car, its standard, only thing the guy has done to it is turbo timer and alarm, headunit change.

No engine mods.

If its a boost cut, what can i do? I dont think its fuel cause the engine still rev's up, Could it be air?

He did have the turbo re-cond, could it be possible the turbo is trying to boost too much?

Whats the best thing to do to try sort the problem? or am i best to take it to a garage the specilises in performance vehicles?

(i have searched the other posts on boost issues, but cant really find a solver, other than clean the MAF, clean air filter, test boost, but no boost guage)

[KwS]

id get a boost gauge on there ASAP and see how high its going. A good test would be to bypass the boost control system and run wastegate pressure, see if it still happens.

Remove line 3 from t-fitting on line 1/2, then block t-fitting to close the line. You could use an off-cut of vacuum hose with a bung/goof plug in one end and fit other end to the T. Just make sure the bung is tight and secure, if it pops out the wastegate actuator will not open properly causing the turbo to free boost, which will damage the turbo and/or engine.

[D3ft0n3s]

so put a piece of hose with bang on the t. but do what with the original pipe from t?

what can I expect to happen with various problems?

[D3ft0n3s]

update noticed it doesn't matter how hard I push the accelerator its still doing it to some degree

[KwS]

If its running wastegate pressure itll be running less boost than normal (around 7psi), so if it is hitting boost cut, it would cease to happen at WG pressure. If it still happens, its not boost cut.

... much more investigation took place, and, found that some B*stard, has put the air filter box back on and broken the hinge side of it (closest to the motor) so there is now a bit of a hole there. Also, IMO the filter needs replacing.

So the question is this, would that cause my issue? If i change to a POD will that fix the problem ? (i imagine that to be cheaper than trying to find an original air box and the other bits that arent there). Also, since it has the AFM right at the end of the intake pipe, is it hard to install a POD?

A mate suggested could be BOV not holding pressure enough (broken / worn spring) i dont know enough about them, but that sounds feesible.

[KwS]

Hole in airbox causing issue? Not likely.

[D3ft0n3s]

What bout the suggested bung BOV?

Whats the most likely?

[KwS]

get a boost gauge, run WG pressure. Eliminate one thing at a time, in this case id start with overboosting.

[D3ft0n3s]

K cheers mate

*trundles off to spend more money *

[D3ft0n3s]

k checked MAF looked black one side. that do it?

[D3ft0n3s]

If anyone cares...........

Took it to a specialist, tested everything, found MAF was leaning out car, swapped for new MAF, good, but charged turbo system with compressed air, found it to be leaking underintercooler.

so hopefully all fixed

What ever you do m8 dont install a POD!!!!!!! - will root your turbo

are you for real? that's the biggest crock of s*** on this forum.

show me any evidence of this . i run a pod and my turbos fine along with millions throughout the world and i dont see turbos imploding everywhere

sorry I may be wrong about stuffing turbos - people have told me that before thats all - but read this - quoted

Once upon a time they were used to replace stock airboxs and air filters as these were a restriction in the intake,with modern design and processes,the restriction is less in the stock item,so replacing it with a pod filter has become less of a performance gain and more of a "bling" factor,there is also a few other downsides to fitting of a pod filter,one being as mentioned vibration,and the damage it causes to your airflow metre,also if the pod in an oiled design,this has detrimental effect on the airflow metre if it is of hot-wire design, and lastly heat the original air box gets cold air routed to it from outside of the engine bay,so with out encapsulating the pod filter in a cold air box and running a cold air intake,you will end up sucking warmer air which will be detrimental to your performance

[rex-leggy]

seriously dont believe everything you read yes vibrations can stuff afm's but if they were installed correctly then there wouldn't be a problem .

99% sure that the whole oiled filter thing is a myth which was used as the blame for engines imploding. have you ever oiled a filter? not that much goes onto it
